The heat wave lasts several more days but not without the chance for storms!

Posted: Updated:


We're just one degree away from hitting 90 at the noon hour!  When it does get to 90 degrees this afternoon, it will be the 5th consecutive day of 90 plus degree heat here in CT, and we're not quite done with the heat yet.  Read on for more details.

A Heat Advisory is in place for much of Connecticut through the day today. Additionally, an Air Quality Alert is in effect for portions of the state.


The brutal combination of heat and humidity will continue for several more days.  In fact, Heat Advisories and an Air Quality Alert have again been posted for today as we're experiencing similar conditions to what we experienced Yesterday.  Inland, expect highs between 90 and 95… but factor in the humidity, the heat index will top out between 100 and 105.  Some relief can be found at the coastline where highs will be in the 80s. 

While it has been a dry stretch so far, that's expected to change later today.  A cold front that generated thunderstorms well west of Connecticut during the day yesterday is heading in our direction.  While it is weakening considerably as it moves towards us, we still run the risk for afternoon and evening showers and t'storms.  While many towns will remain dry, where storms do pop up, rain could be heavy and accompanied by frequent lightning. 

For Wednesday, the 4th of July, we expect more of the same:  heat and humidity, but an even lesser chance for an isolated storm.

Thursday will likely be our last day 90 or higher, making it a 7day heat wave! 

Friday, a stronger cold front will move into the region bringing the chance for rain and thunderstorms – especially during the afternoon and evening.  As of now, storms that develop could be potent, potentially strong to severe… we’ll keep you updated as we get closer in time.  Highs will likely be held into the 80s.


Behind the cold front that will bring unsettled weather Friday, a comfortable weekend is on tap!  We’re currently forecasting lower humidity and dry, bright weather both days.  It will also be cooler, more seasonable with highs in the lower 80s!

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!
