For any Alerts in effect for CT, click: here.

THIS MORNING…

Temps have dropped quickly this morning. We’re 25 degrees colder in spots compared to yesterday at this time, brrrr. Under a clear sky, temps bottom out between 20 and 25 in most locations. For comparison, the normal low for the Hartford Area is 29. The usual colder spots of NW & NE CT could dip into the teens. And please don’t forget about the breeze. While much better than yesterday, it’s still out there to a degree, making temps feel even colder this morning, bundle up!

THE REST OF THIS WEEK…

Our Hump Day will be dry and chilly, but the wind will be calmer. Therefore, temps that peak below average – in the upper 30s – won’t feel notably colder. Tomorrow, temperatures head back to near-seasonable levels under a mix of sun and clouds. A weak disturbance brings the chance for isolated rain or snow showers at night. However, we’re not anticipating any impacts for the Friday AM commute. Speaking of Friday, astronomical spring begins with the vernal equinox occurring at 10:46 a.m. After a bright start… the afternoon will be milder, though cloudier, with temperatures near or above 50.

THE UPCOMING WEEKEND…

The weekend, as of now, could be bookended with showers. Meaning, showers early Saturday then late Sunday. In-between, plenty of dry time. Otherwise, both days will be breezy with temperatures peaking between 50 and 55.

NEXT WEEK…

In the wake of a cold front that clears CT early Monday, any lingering showers end and cloud cover gives way to sunshine. Temps peak in the mid-40s. Tuesday looks dry and bright with temps similar to Tuesday.

MARCH RECORD WARMTH…

Last Monday, the 9th, was one for the record books, at least in Bridgeport where the record high of 64 from 2021 was tied! Meanwhile, for the Hartford Area, it was mild but not warm enough to get remotely close to the March 9th record of 81. The temp managed to hit 70, the first time to do so since October 19th!

While Monday was notable for the shoreline, Tuesday, March 10th was record-shattering for the Hartford Area as the temperature reached June-like levels. The March 10th record high was 72 from 2016 – we hit 79! Wednesday was also unseasonably warm, with an official high temperature of 74… just *1* degree shy of the record of 75 (set in 1977).

METEOROLOGICAL WINTER…

Meteorological winter ran from 12.01 to 02.28, and it was both cold and snowy compared to average. The average temperature was 25.6°, a full 4.1° below average. During the season, 52.3″ of snow fell, 13.2″ more than normal. In Bridgeport, an impressive 55.9″ of snow fell, which is a whopping 31.2″ above average!

BLIZZARD CALVIN…

Three NWS sites met blizzard criteria in Connecticut: Bridgeport, New Haven and Groton/New London. The criteria? Visibility of 1/4 mile or less and wind speeds (sustained or frequent gusts) of 35 mph or higher… over at least a 3 hour period. Additionally, the snowfall reports were impressive. Shoreline towns, especially in southeastern Connecticut, received 20″ and higher, with an official report of 30.8″ in Stonington and 2 feet in Mystic. Wind gusts reached 55 mph along the shoreline.

We named this storm Blizzard Calvin, following our naming tradition that dates back to 1971. The last blizzard in our area was over a decade ago, Blizzard Charlotte, in February of 2013. While it dropped 22.3” in the Hartford area, the jackpot was in Hamden where 40″ was measured!

WINTER STORM BENJAMIN…

Winter Storm Benjamin was the biggest snowstorm CT has experienced in almost a decade. The Hartford Area received 17.3″, beating out the 16.2″ that fell between February 18-19 in 2017. It produced a widespread 12-20″ of snow with some locally higher amounts. The jackpot was in Falls Village, where 22.0″ fell! While there was a bit of sleet that mixed in along the shoreline, official observations still eclipsed the 12″ mark.

The snow ramped up on Sunday, January 25th, spreading across Connecticut around sunrise. Snowfall rates were increasing quickly, with observed rates of 1-2″ by the afternoon. With air temperatures in the single digits, there was certainly a fluff factor at play! This also meant it felt cold outside… with the breeze, wind chill values were below zero for most of the day. The snow came down steadily and heavily through the evening, tapering off at night.

DID YOU FEEL IT, HEAR IT?

At 5:36 pm Wednesday, January 7th, the seismometer at the East Haddam Historical Society Museum measured a small earthquake. According to the USGS, it was located 1 miles south of Moodus, 5.6 miles deep and measured 1.9 magnitude. These quakes/tremors lead to the commonly known “Moodus Noises” that historically occur near/around Moodus, hence the name.

2025…

The numbers are in, and 2025 did not have big departures from average. The average temperature was 51.5°, 0.5° above normal. August, November and December were cooler than normal, but the rest of the year was warmer. Total precipitation (rain and the liquid equivalent of anything frozen) was a little below average with a total of 46.63″. This is only 0.42″ shy of average (the Hartford Area averages 47.05″). Snow for the calendar year was below average, too. Only 27.2″ fell, while average is 51.7″. There were *0* confirmed tornadoes in Connecticut, the first time since 2017.

WINTER STORM ABRAHAM…

An area of low pressure moving just to our south brought the first significant snowfall of the season – and our first named storm of winter – to Connecticut. Snow began on the evening of Friday, December 26th and continued overnight through the morning of Saturday, December 27th before dissipating.

Bands of heavy snow brought observed snowfall rates of 1-3″ per hour at times Friday evening. Winter Storm Abraham produced over 6″ of snowfall in many areas. Some of the highest reports were across central and western CT: New Milford – 10.5″, New Preston – 9.9″, Meriden – 9.0″, Naugatuck – 8.5″, Higganum – 8.0″ & Bristol- 8.0″.

DECEMBER 19 RECORD WARMTH, WIND AND RAIN…

A potent storm system moved through the Great Lakes on Friday, December 19. Ahead of the cold front, southerly winds across Connecticut gusted up to and over 60 miles per hour! Some notable gusts: 67 mph in Groton, 64 mph in Willimantic, 63 mph in Middletown, 60 mph in Berlin. Scattered power outages were reported across Connecticut. Also, about an inch of rain fell throughout Connecticut.

That strong southerly wind brought record warmth to Connecticut. For Bradley, where the Hartford Area records are kept, the temperature peaked at 58… beating the old record of 54 (set in 1949) by several degrees. In Bridgeport, the temperature climbed to 57, tying the record of 57 set in 1967.

DECEMBER 5 RECORD COLD…

High pressure moved in behind an Arctic front on December 5. Low temperatures were in the single digits and teens.

The Hartford Area fell to 5 degrees. The record is 3, set in 1976.

DECEMBER 2 SNOW, ICY MIX AND RAIN…

On December 2, a coastal storm brought a mix of snow, freezing rain, sleet and rain to Connecticut. It began in the morning and wrapped up in the evening. Snow accumulated along and northwest of I-84, with the highest totals close to the Massachusetts border (5.0″ in Canaan, 4.0″ in Simsbury).

OCTOBER 10th COLD WEATHER…

With dry air and a calm wind under a clear sky… the temperature dropped to 29 degrees at Bradley thus tying the record set back in 1989! This is also notable since the last time the temp (for the Hartford Area) was below 40 was back on May 12th, the last time it was lower than 35 was on April 21st! Bridgeport got down to 40, nowhere near the record of 33 set back in 1979.

AUGUST ‘25 & METEOROLOGICAL SUMMER…

August 2025 finished with an average temperature of 69.6°, and impressive 2.9° below normal. This is also noteworthy as it is the first month since November ‘23 to finish below normal, ending a stretch of 21 consecutive months warmer than normal! A total of 2.45″ fell for the Hartford Area (as measured at Bradley International Airport), 1.76″ below normal.

Meteorological summer ran from 06.01 to 08.31, and it was pretty close to normal for the Hartford Area. The average temperature was 72.2°, just 0.3° above normal. During the season, 12.39″ of rain fell, only 0.27° below normal. In Bridgeport, however, it was quite dry… only 3.85″ of rain fell during the entire season!

August 20th was a chilly, raw day in Connecticut.

HEAT & SEVERE STORMS FRIDAY, 07.25…

Temperatures soared into the 90s ahead of a cold front on Friday. When you factor in the high humidity, it felt more like the low 100s across much of the state! The high for the Hartford Area was 95. For Bridgeport, the high was 94, breaking the old record of 93 from 2001. A cold front moving into this hot, humid air mass led to strong and severe thunderstorms. There were multiple trees down across the state, especially through Litchfield and New Haven counties.

——————

2nd HEAT WAVE OF ‘25…

The temperature hit 90 at Bradley Airport Tuesday, July 15th, then 93 Wednesday, and 90 Thursday. With 3 consecutive days 90 or higher, we achieved our 2nd heat wave of ’25.

——————

WET WEEKEND STRETCH…

Connecticut’s 18-weekend streak of precipitation at Bradley International Airport (BDL) came to an end on the weekend of July 5/6. This remarkable stretch began on February 22/23, and was defined by at least a trace of precipitation falling on either a Saturday or a Sunday.

During this extended period, rain was the typical culprit, the wettest weekend day being Saturday, May 31 when 1.45” of rain fell. But it also included a late-season snow event on Saturday, April 12th when 1.5” of snow was recorded at Bradley; a notable contribution to the precipitation record.

——————

JULY 3rd SEVERE STORMS…

A cold front on Thursday, July 3rd sparked severe thunderstorms across Connecticut. Wind gusts were quite strong with a 49 mph gust measured at Bradley International Airport. Many towns reported downed trees, leading to power outages. In fact, over 27,500 people lost power! Unfortunately, a tree fell onto a car in Trumbull and injured one person. The storms also brought hail, particularly in parts of NW and NE CT. Hail covered roadways in Danielson. The largest was golfball size (1.75″ diameter) reported in Sterling, CT.

1st HEAT WAVE OF ‘25…

We need 3 consecutive days 90 or higher to qualify for a heat wave, our 1st one of the year lasted 4 days. Sunday (06.22), at Bradley Airport the temp topped out at 92. Monday’s high of 98 set a record in the Hartford Area for June 23rd (prior record was 97 from 1965). Tuesday, the temp reached 90 in the 10a hour (making the heat wave official) then peaked at 99 which also was record-setting (previously 94 from 2013). Tuesday (06.24) also joined the ranks of hottest June days since 1905: 100 has been achieved twice (in 1952 and 1964), previously 99 was only achieved once (on the 29th in 2021, also the last time it was *this* hot!). Wednesday (06.25), the high of 95 tied the 1943 record.

For Sunday, Monday, and Tuesday… Bridgeport hit 93, 94, and 95 – respectively, all setting daily record highs. Wednesday, the high of 97 not only set a new record for June 25th, but also tied June 9th, 2008 for warmest June temperature since 1948!

On June 24th, the heat also broke records for “warmest low” temperature both in the Hartford Area (a 116 year old record) and in Bridgeport. For the 25th, records were again broken for “warmest low” at both locations.

——————

90° HEAT…

Thursday, 06.05, was our first 90° day of the year (and since August of last year), with a high of 93 at Bradley Airport (where official records are kept for the Hartford Area). For Bridgeport, the high of 87 broke the prior June 5th record by 1° set in 2021.

——————

MAY 22nd NOR’EASTER…

The nor’easter produced over 3.0″ of rain across SE CT! In the same area, wind gusts eclipsed 30 mph. To add insult to injury, it was unseasonably cool — statewide — with highs in the upper 40s and lower 50s (closer to our normal overnight low for this time of year)! And get this, we have tied the over 100 year old May 22nd record of 49 (from 1909) for lowest or ‘coolest’ high temperature in the Hartford Area! For Bridgeport, the high was 52… breaking the record lowest high of 54 from 2005!
