Thunderstorms will end tonight and the heat wave is over!



Rain and storms moving through the state in association with a cold front will end from northwest to southeast this afternoon. Clouds will clear as well, with humidity dropping during the afternoon from northwest to southeast, as drier air filters into the state. This will set the stage for a gorgeous Friday evening!

The weekend forecast is on track, read below for more!

With a high of 92 degrees at Bradley, July 5th marks the 7th day of this first heat wave of 2018; it’s also the 13th 90° day for the year.

Here’s a breakdown of the heat wave, with high temperature by day:

Fri, 06.29: 90… Sat, 06.30: 93… Sun, 07.01: 98… Mon, 07.02: 95… Tue, 07.03: 95… Wed, 07.04: 94… Thu, 07.05: 92.


The week ends with wet, unsettled and initially humid weather. Rain and thunderstorms will be likely from this morning into the early afternoon hours as a cold front pushes into Southern New England. Given this timing, the threat for severe weather is not high (as opposed to if the front were to arrive later in the day). The primary concern with storms will be heavy rain that could lead to localized, poor drainage flooding. There's a FLASH FLOOD WATCH in effect for Southern Fairfield, Southern New Haven, all of Middlesex and all of New London Counties through 5pm. With any thunderstorm there could be lightning, also a gusty wind could accompany stronger ones that develop. The front will move offshore by 5pm today with clearing taking place in its wake. As it moves away, the wind switches to the west and northwest, filtering drier and cooler air into the state. You will certainly notice a difference if you’re out and about Friday evening!


Behind today’s cold front, we are in for a comfortable/amazing/spectacular weekend of weather! Not only will the humidity be dramatically lower, it will be cooler. We expect highs in the lower 80s tomorrow (a few degrees below average for a change). Then Sunday, we start out in the 50s… YES, 50s (!), then warm into the mid-80s during the afternoon. Both days will feature abundant sunshine with high pressure in control.


Temperatures will start heating up, again. Monday looks to be dry and seasonably warm with highs in the mid to upper 80s under a mostly sunny sky. Then Tuesday, inland, we close in on the 90 degree mark! Wednesday, as of now, appears to feature a mix of sun and clouds with just a slight chance for a shower or storm. Highs through the middle of next week look to be a tad above average, between 85 and 90.

The longest heat waves on record in Connecticut lasted a total of 10 days. There was a 10-day heat wave in the summer of 1995 from July 24th through August 2nd. There was another 10-day heat wave in the summer of 2016 that lasted from July 21st through July 30th.

The most intense heat wave was in July of 1991 when we had 3 consecutive days of 100-degree heat! It was 100 on the 19th, 100 on the 20th, and 101 on the 21st!
