September was yet another non-typical weather month for Norfolk. It did not feel that warm or wet all month, but the final monthly totals told a different story. In just a period of about three days, remnants of a Gulf Coast landing hurricane and then three weeks later a strong cold front combined to produce a vast majority of the month’s rainfall. Without these two relatively short duration rain making events, September would have come in as one of Norfolk’s driest Septembers on record. It was a poor foliage season for the area’s sugar maples, a casualty of our wet summer and fall, but there was fall coloring and it began to be quite noticeable by the middle of the month. By the end of the month, local swamps were all showing off their beautiful classic red glory. It is debatable, but some say the foliage change this fall was a little later than usual.
September’s high temperature of 81 degrees was observed on September 15 and the low of 43 degrees was observed on September 29. The month’s average mean temperature was 61.5 degrees, 2.5 degrees above normal. This month was tied with 1946 and 1971 as Norfolk’s 11th warmest September. Norfolk’s warmest September was in 2015 with a mean temperature of 64.7 degrees. The coolest was in 1963 with 53.6 degrees. There were no daily temperature records set this month and there was no frost anywhere to be found in Connecticut. Last year the first frost came to some Norfolk locations by September 15, with the first widespread frost occurring on September 21. It is fairly normal for some parts of Norfolk to see a few frosts in September. This September was just too warm for that. It did extend the growing season though.
The month’s rainfall total was 8.80 inches, 4.13 inches above normal. Nearly 90% of September’s monthly rainfall came from two relatively short duration rain events. That seems wild, but it actually is not all that uncommon. This September came in as Norfolk’s 9th wettest September. Norfolk’s wettest September was in 1938 with 13.40 inches and the driest was in 2014 with just 1.16 inches.
Through September this year, the total yearly precipitation amount was 48.58 inches. This was 9.56 inches above normal through the third quarter of 2021. A very interesting fact is that after September of 2020 Norfolk’s precipitation total was just 29.18 inches. That was 9.96 inches below normal and 19.40 inches less than this year’s running total. Talk about a complete switch from one year to another. The year of 2020 ended up being Norfolk’s 18th driest year on record. With still three months to go in 2021, if our above average monthly precipitation continues to occur, Norfolk could be flirting with a Top Ten wet year.
In a preview of October’s weather, through October 21, it was much warmer than normal. It is very likely that this October will rank very high for warm Octobers. There were a few reports of very light frost in some lower elevation valley locations on October 7 and 19, but still no widespread frost and just a few days with that typical October chill in the air. Rainfall was about normal with most of the month’s current total of 2.71 inches coming during a rain event on October 3-5. Norfolk’s foliage season “number one” (maple and ash) was about over by October 21, with foliage season “number two” (oak and beech) yet to come. The peak day for foliage this year was hard to pinpoint. The forecast is for weather patterns to change during the final week of the month. Winter is (slowly) approaching.
August’s weather for Norfolk was greatly affected by hurricanes and tropical storms. Not storms that made Connecticut landfalls, but storms that struck in the Gulf Coast region and just to our east in Rhode Island. The remnants of these once dangerous storms mostly lost their punch by the time they made it to our state, but they still brought considerable rain to the region. There was little wind damage here, but the rain seemed relentless and there were flooding concerns. August had an abundance of cloudy, but also humid days. No record high temperatures were set this month. Overall, it was warmer than normal and like July was wetter than normal.
August’s low temperature of 49 degrees was observed on August 1 and the high of 89 degrees was observed on August 12. The monthly mean temperature of 69.8 degrees was 3.4 degrees above normal. It did not seem like it was that warm, but this August was Norfolk’s 6th warmest August over the last ninety years. Norfolk’s warmest August on record was in 2001 with a temperature of 71.0 degrees. The coolest August on record was in 1964 with 61.5 degrees.
The total precipitation recorded for the month was 6.33 inches, 1.73 inches above normal. This August was Norfolk’s 11th wettest August on record. Norfolk’s wettest August, and wettest month of any month, was in 1955 with 23.67 inches. One cannot write about August rainfall totals without mentioning The Flood of ’55 that hit this area so hard back in August 1955. Norfolk’s driest August was in 1953 with just 0.65 inch, which was also Norfolk’s fifth driest month of any month. The month of August can have big swings for precipitation amounts. What we experienced this summer was that not only can hurricanes and tropical storms (or the lack of them) really affect our summer rainfall totals, but the remnants of these storms can also play a large role.
Through August, the total precipitation amount for the year was 39.78 inches, 5.43 inches above normal. By comparison, this was 15.27 inches more than last year’s total through August. The summer of 2020 was a dry one. The summer of 2021 has been the opposite. Last summer the talk was all about the drought, this year it is all about the excessive rainfall.
September brought more of the same for weather in Northwest Connecticut. Remnants of another hurricane that made landfall in the Gulf Coast dumped 4.34 inches of rain on Norfolk during the first two days of the month. It was then fairly dry for a few weeks until a slow moving cold front produced 3.28 inches of rain in a short period of time. Both measurements were 24-hour rainfall totals. That is impressive. By September 25, the monthly rainfall total of 8.52 inches was already 3.85 inches above normal. Another wetter than normal month for Norfolk. Through two-thirds of the month, temperatures were running on the warm side and there was no talk of frost. Yes, frost can occur in September in the Norfolk area. Fall foliage was quite noticeable by mid-September. The sugar maples seem to be having an off year, likely due to the excessive rainfall. The leaves have begun their color change and it will not be long before the weather finally follows suit and turns more fall like.
On average, July is Norfolk’s warmest month of the year. July of last year was the warmest July, and also the warmest month of any month, on record for Norfolk. July of this year might technically end up being the warmest month of 2021, but it sure did not feel like it. The month started out cool and rainy and the rain did not stop for the rest of the month. Norfolk’s weather for its Independence Day Weekend was about as nice as its Memorial Day Weekend. Neither had particularly nice weather. The high temperature of 58 degrees on July 3 was the same as the high temperature recorded last Christmas. Both dates do not typically hit 58 degrees, at least in Norfolk. The big storyline for July’s weather this year was not temperatures, it was rainfall.
July’s high temperature of 86 was observed on July 7 and the low of 48 was observed on July 31. The average monthly mean temperature of 67.6 degrees was 0.7 degrees below normal. Not high ranking for cool months of July, but it was the first month of 2021 that came in below average for monthly temperature. The warmest July was in 2020 with 73.1 degrees and the coolest was in 1962 with 63.9 degrees. This July’s persistent cloudy and rainy weather definitely had an effect on its temperatures.
The total precipitation recorded for the month was 13.05 inches, a whopping 8.72 inches above normal. Norfolk’s average July total is 4.33 inches. Rainfall was observed during the first fifteen days of the month. A dreary start. At month’s end, twenty two of the month’s thirty one days had observed rainfall during part or all of them. Perhaps fortunately, there were no direct hit huge storm events like a hurricane or tropical storm. The rainfall was just persistent and often reached two to four inches over a few day span several times during the month. As a result, there were no major local flooding issues. There were, however, some issues caused by the excessive and persistent amount of rainfall that occurred all month. With no dry out period, streams and rivers stayed fairly full and the ground stayed saturated for most of the month.
On the plus side, the running yearly precipitation deficit of 5.02 inches after June was transformed into a surplus of 3.70 inches after July. There should be no talk of drought conditions around Norfolk, or the Northeast U.S. for that matter, for quite a while. Perhaps all of the “we need rain comments” from earlier in the year came back to haunt us during July. Through July, the 2021 total precipitation amount of 33.45 inches was 3.70 inches above normal. The average yearly total precipitation amount for Norfolk is 52.53 inches. Total precipitation includes rain, snow and sleet.
An early look at August’s weather through mid-month showed a continuation of July’s mostly cloudy conditions. Norfolk fortunately saw a bit of a dry out period during August’s first two weeks. There were a few days with typical hot and humid summer weather, but all in all, temperatures and rainfall were running about average for the first half of the month. Looking ahead, there were some tropical storms and hurricanes brewing in the Atlantic, as usually occurs during August. The latter half of the month could get interesting weather-wise.
As it was last year, June was a very pleasant summer month for weather in Norfolk. Temperatures were on the warm side and there were many clear, sunny days without too much humidity. There was rain scattered throughout the month, but Norfolk didn’t see much for rainfall totals even when it did rain. Parts of the state, and the Northeast in general, did get a decent amount of rainfall in June. The storms producing higher rainfall totals just kept missing Norfolk this month. It was on the dry side, but not dry enough to cause browning of lawns or dried out gardens.
June’s low temperature of 41 degrees was observed on June 1 and the high of 91 was observed on June 29. An impressive fifty degree temperature differential. With an average monthly mean temperature of 66.8 degrees it was 3.4 degrees above normal. This June was tied with June 1999 as the fourth warmest June over the last 90 years. There were two days this month that reached 90 degrees or higher; June 29 recorded 91 and June 30 recorded 90. Norfolk gets to 90 or above on average about two or three times a year. There were two days with daily record high temperatures this month; June 6 with 87 degrees (was 85 in 1934) and June 7 with 88 (tied the 2008 record). Norfolk was close to daily record highs on June 5, 8, 27, 28 and 30. The highest temperature ever recorded at this weather station was 101 degrees, it occurred on June 29, 1933. Norfolk’s warmest June was in 1943 with 68.3 degrees, the coolest was in 1958 with 58.8 degrees.
The total precipitation recorded for the month was just 2.01 inches, 2.80 inches below normal. It was Norfolk’s ninth driest June over the last 90 years. The driest June was in 1988 when only 0.61 inch was recorded. The wettest June was in 2013 with 13.38 inches. There were four relatively small thunderstorms this month, occurring on three days. The largest storm rainfall total was 1.12 inches, occurring during the morning of June 14.
For the first half of 2021, Norfolk’s total precipitation amount was 20.40 inches. This was 5.02 inches below normal though the month of June. A five inch deficit is not too bad yet and fortunately there currently are no widespread drought concerns here in the Northeast. Let us hope that things turn around a little for Norfolk and we pick up more beneficial rainfall in the coming months. A few summer thunderstorms can help bring up the total in a hurry.
An early look at July showed that we most certainly made huge gains towards reducing our yearly precipitation deficit. In fact, during the first three weeks of the month our deficit was changed to a surplus. The normal monthly rainfall amount for July is 4.33 inches. By July 22 this year the total was already a whopping 11.74 inches. With a week and a half yet to go, July 2021 was already the second wettest July over the last 90 years. Another inch or so will make this July the wettest on record.
For the first nineteen days of July, rainfall occurred on eighteen of them. Not surprisingly with all of the rainy weather, temperatures were running a little below normal for the first three weeks of the month. July 2020 was the warmest on record, could July 2021 be the wettest? Stay tuned.
May started out cooler than normal and through mid-month was very much on the cool, cloudy and rainy side. The raw feel made many people wonder where early summer was. Conditions changed towards the middle of the month with warmer temperatures and sunnier skies. That was right up until Memorial Day Weekend, the unofficial start of summer. It was a very cool and wet weekend, perhaps some of the worst weather we have seen here for Memorial Day Weekend in a long time. A wind chill of 30 degrees and nearly two inches of rain on May 29 put a damper on many planned outdoor activities. But, we needed the rain, right?
May’s low temperature of 33 degrees was observed on May 1 and the high of 86 degrees was observed on May 26. With an average monthly mean temperature of 55.0 degrees, it was just 0.1 degree above normal. There were no record daily temperatures this month. Norfolk’s warmest May occurred in 2015 with a temperature of 61.8 degrees, the coldest was in 1967 with 46.8.
The total precipitation recorded for the month was 7.75 inches, 3.41 inches above normal. This was the first month of 2021 that was above average for total precipitation. This May had reached its normal amount for precipitation by about May 26, then we received nearly another four inches during the following several days. It ended up being tied with 1940 as Norfolk’s fourth wettest May over the last 90 years. It took a big bite out of 2021’s precipitation deficit. Through May, the total precipitation for 2021 was 18.39 inches, now just 2.22 inches below normal for the year. Norfolk’s wettest May was in 1984 with 12.34 inches, the driest was in 1980 with 1.31 inches.
Although it felt cold and raw enough for snow on many days, there was no snowfall recorded this May. This was 0.4 inch below normal, but there have been many Mays without any snowfall. Norfolk’s winter season snowfall total for 2020-2021 ended up being 77.6 inches, 11.5 inches below normal. Norfolk’s 2021 snowfall total through May was 53.5 inches, 11.3 inches below normal. February’s snowfall of 35.0 inches makes up a majority of these snow totals. Norfolk’s (and Connecticut’s) snowiest May on record (by far) was in 1977 when an amazing 20.0 inches was recorded.
An early look at June’s weather through mid-month shows that temperatures were running about two degrees above normal. Precipitation was below normal, but a good thunderstorm or two can go a long ways towards increasing monthly and yearly totals. By June 15, Norfolk had observed three June thunderstorms. Two thunderstorms occurred on June 14, and while short in duration, they both came with some wind, numerous lightning strikes and some brief heavy rainfall. Summer has arrived in Norfolk.
April can have traits of both winter and spring. March was unusually pleasant with hardly any snow. April followed that with some warmer temperature, as would be expected, but April also had more snowfall, more rainfall, and more cloudy days than March. Even with some snow and many cloudy days, spring did arrive in Norfolk as it usually does in April.
One day this April stood out for being quite wild for weather. On April 21 it was 34 degrees in the morning, by early afternoon it was 63 degrees. Then a strong cold front with a tornado warning label came through at about 3:00 pm. Norfolk only recorded 0.16 inch for rainfall, but there was brief pea-sized hail. This cold front did produce two small tornados in Kent, CT and Amenia, NY. In Norfolk the temperature dropped 21 degrees in 25 minutes and by 5:00 pm with temperatures in the low 30’s there were snow flurries in the air. Overnight into the next morning Norfolk was blanketed with nearly an inch of snow.
April’s low temperature of 17 degrees was observed on April 3. This tied the 1978 record daily low for that date. The high of 77 degrees was observed on April 28. There were no daily record high temperature in April. With an average monthly temperature of 45.4 degrees, it was 2.3 degrees above normal. This April was tied with 2012 and 2019 as Norfolk’s 20th warmest April over the last 90 years. Norfolk’s warmest April was in 2010 with 49.4 degrees and the coldest was in 1943 with 36.8 degrees.
With 90 years of weather observing for the month of April, over the last 20 years there have been five April’s ranked in the top ten for warmest Aprils. Over the last 20 years there has been one April ranked in the top ten for coldest.
The total precipitation recorded for the month was 2.87 inches, 1.41 inches below normal. Through April, the total precipitation for the year was 10.64 inches, 5.63 inches below normal. Norfolk’s wettest April was in 1983 with 10.79 inches, the driest was in 1941 with 1.15 inches. April’s snowfall total was 6.0 inches, just 0.1 inch below normal. Although it seemed to be a snowy April, it really was near normal. There have been many Aprils with no snowfall or just a trace of snow, the snowiest April was in 1997 with 31.1 inches.
Through April, the 2021 calendar year snowfall amount of 53.5 inches was 10.9 inches below normal. The 2020-2021 winter season (October-April) snowfall total of 77.6 inches was 11.1 inches below normal, about in the middle of the pack for seasonal snowfall over the last 90 years. Norfolk’s snowiest season was in 1955-1956 with 177.4 inches, the least was in 2015-2016 with just 35.5 inches.
A look ahead at May’s weather through mid-month showed that temperatures were running about six degrees colder than normal. It was a cool and cloudy first half of May. By the third week of the month it did warm up and a few days with temperatures in the 80’s helped bring the monthly average up to near normal. There was no snowfall, but there was a decent amount of rain for a change. As usual, this may carried Norfolk from a brown spring look to a green summer look in the span of a few weeks.
An accurate description of March’s weather would certainly be unusual. March weather was high ranking for temperature, lack of precipitation and it topped the rankings for least snowfall. If you were looking for sunny skies, warm temperatures and hardly any snow, then March was your month. March is not typically described in this way. After a very traditional cold and very snowy February, it was quite the rebound for March to come in so pleasant. As can happen in March though, there were many windy days. This March had more than its fair share of wind. Nothing too dramatic, just an abundance of windy days (and nights).
All local ponds and lakes lost their ice by the third to fourth week of the month. Tobey Pond and Wangum Lake both went out during the day on March 26. The ice-out dates this year were about average for the last twenty years. The lack of a real January thaw and February’s cold and snow helped make the ice thicker this year than it has been in recent years. The thicker ice also likely contributed to it staying longer this year than in recent years. Smaller ponds formed ice, and kept it, by December 15 (about average), the larger water bodies did not ice over until January 10-12 (a little later than average).
March’s low temperature of 7 degrees was observed on March 2 and the high of 72 degrees was observed on March 26. Two new record daily high temperatures were set this month; a high of 71 on March 25 (was 66 in 1987) and a high of 72 on March 26 (was 68 in 1945). With an average monthly temperature of 34.2 degrees, it was 3.5 degrees above normal. This March was tied with March 1991 as Norfolk’s sixteenth warmest March over the last 90 years. Norfolk’s warmest March was in 2012 with 41.8 degrees, the coldest was in 1960 with 21.2 degrees.
The total precipitation recorded for the month was 2.24 inches. This was 2.10 inches below normal. It was Norfolk’s tenth driest March and makes for the third month of 2021 that was below normal for total precipitation. Norfolk’s driest March was in 1981 with 0.64 inch, the wettest was in 1953 with 10.37 inches. Through the first quarter of 2021, the total precipitation amount was 7.77, 4.22 inches below normal. Once again, a deficit is slowly growing.
The lack of snowfall was this month’s big surprise. March’s snowfall total of just 0.1 inch was 17.4 inches below normal and ranks this March as the least snowy March on record. The old record was 0.5 inch from March 1946. The March with the most snowfall, also the snowiest month of any month on record for Norfolk, was in 1956 with 73.6 inches.
Through the first quarter of 2021, the total snowfall amount was 47.5 inches, 10.8 inches below normal. The 2020-2021 winter season (October-March) snowfall total through March was 71.6 inches. This was 11.0 inches below normal. February’s snowfall contribution of 35.0 inches produced nearly half of this season’s snowfall.
Through April 20, April was looking fairly normal for temperature, precipitation and snowfall. A 4.6 inch snowfall on April 15-16 was a surprise, but April’s average monthly snowfall amount is 6.1 inches, so spring snow does happen regularly here in Norfolk. Snow can also happen in May here in the Icebox of Connecticut and because of this, the season snowfall total will not be finalized until the end of May.
February was a snowy month. After several years of rather soft winter weather in what is typically wintertime, it seemed as if this February was so much colder and so much more snowy than normal. In fact, it was rather normal temperature-wise, but there was more snowfall than average. Not record setting snowfall by any means, just more than average. Plus, with the more normal wintertime February temperatures, what snow we got, stayed on the ground for the entire month. It was a good old fashioned winter month. This made for happy people looking to ski, skate or go ice fishing and generally anyone else that enjoys snow and typical Norfolk winter weather.
The month’s low temperature of 4 degrees was observed on February 12. There were five days this month with single digit temperatures, but no days recording zero or below zero. The high temperature of 46 degrees was observed on February 24. There were no daily record high or low temperatures this month. The average monthly temperature was 22.8 degrees, just 0.6 degree above normal. It was the coldest February in Norfolk since 2015. February 2015’s average temperature of 10.9 degrees was Norfolk’s second coldest month of any month since 1932. The warmest February on record was in 2002 with 30.7 degrees. The coldest was in 1934 with 9.0 degrees, making that also the coldest month of any month as recorded at this weather station.
Total precipitation recorded for the month was 3.42 inches, just 0.21 inch below normal. A vast majority of February’s precipitation was in the form of snow, with a small portion coming as freezing rain. Obviously, the month’s cold temperatures played a role in this predominately frozen winter precipitation. The 2021 calendar year (January and February) total precipitation amount of 5.53 inches was 2.12 inches below normal. The record for most February total precipitation is 11.70 inches from 1981, the least amount is 0.60 inch from 1987.
February’s monthly snowfall total of 35.0 inches was 14.7 inches above normal. Snow on ground depth during the month ranged from 9 inches to 21 inches, with an average snow on ground of over 17 inches during the month. This month ranked as Norfolk’s eleventh snowiest February over the last 90 years. It was the snowiest February since 2014, then 2010 before that, then 1972 before that. Norfolk’s top seven snowiest February’s occurred between 1940 and 1972. The record for most snowfall in February is 52.4 inches from 1969, the least is 4.8 inches from 1998.
The 2021 calendar year snowfall total through February was 47.4 inches, 6.6 inches above normal. This is over 33 inches more snowfall than the same period last winter. The snowfall total for this winter season, October through February, was 71.5 inches, 6.1 inches above normal for this time period. This is over 31 inches more than last winter season for this time period. Hence, the happiness of the area’s snow loving crowd, from those that try to make a living from snow to those that just play in it.
March is often Norfolk’s transition month between winter and spring. March is a fickle weather month and can throw a wild mix of weather conditions at us. This March through mid-month was much colder than normal with minimal precipitation and minimal snow. It was certainly cold enough for snowfall, but the storms just did not form. The cold kept February’s snow on the ground in most places at least through mid-month. Many local maple syrup producers have reported that this season has been slow due to the cold temperatures. That may change as the forecast for the last quarter of March is for temperatures to increase. Precipitation is needed, so hopefully the warmer conditions also bring some beneficial early spring moisture.
The year of 2020 was Norfolk’s fourth warmest year on record and October through December were all above normal for temperature. Snowfall for the current winter season, however, was about normal through December. What would this mean for January? As it turned out, January was a little warmer than normal and snowfall was below normal, but there was frequent wintry precipitation and there were some cold temperatures. Winter had arrived, perhaps a little soft, but it arrived.
January’s average temperature of 22.9 degrees was 2.1 degrees above normal. It was five degrees colder than January 2020. There were no daily record temperatures this month, but there were four days with single digit temperatures and one day recorded a low of 2 below zero. January’s warmest temperature was a high of 39 degrees on January 2. In all of 2020 there were seven days with single digit temperatures and the low all year was zero. Winter just might have found its way back to Norfolk. Norfolk’s warmest January on record was in 2002 with an average temperature of 31.7 degrees and the coldest was in 1982 with 11.7 degrees.
January’s total precipitation of 2.11 inches was 1.93 inches below normal. The wettest January occurred in 1979 with a total of 11.77 inches and the driest was in 1970 with just 0.74 inch. The monthly snowfall total of 12.4 inches was 8.3 inches below normal. Of January’s thirty-one days, there was some sort of precipitation that fell during sixteen of those days. Only a small portion of the precipitation was plain rain, most was in the form of snow. There was at least three inches of snow on the ground for twenty-eight days during January, with depths ranging from three to eight inches. The snowiest January occurred in 1987 with 50.5 inches. Coming in at second snowiest was January 2011 with 50.0 inches. The least snowy was in 1980 with just 2.6 inches.
The 2020-2021 (October-January) winter season snowfall total through January was 36.5 inches, 8.5 inches below normal. It has not been super winter-like, but it has seemed like a more normal winter than we have experienced in Norfolk for the last few years.
A look at February’s weather through mid-month showed that snowfall and cold temperatures were the norm. Norfolk was seeing a good old fashioned winter. By February 9, we had already exceeded our average snowfall amount for the entire month. By February 16, temperatures were running about two degrees below normal and we were nearly 3.5 inches above normal for snowfall, with more snow in the forecast for later in the month. Unlike previous years when the winter storms seemed to skirt the region, this winter we are getting the storms and on a fairly regular basis. We are not breaking any snow or cold records so far this winter, it is just normal winter for Northwestern Connecticut. Snow lovers had lost their faith over the last two years. It seems that their faith may be restored, as of February anyway.
January 2021 begins the 90th consecutive year of daily weather observing from the Norfolk 2SW weather station. Stay tuned for future weather narratives. While this website is undergoing some improvements, please see below for the weather narratives from the year 2020. Enjoy the weather look back. -Russell
