The heat wave lasts one more day, then it ends with rain/storms!

Posted: Updated:

NOON UPDATE: 

We'll we're not quite at 90 degrees yet. The noon temperature at Bradley International was 87.  We only need three more degrees to get to that magic number, thus making it the seventh day in a row of 90+ degree heat. 

We've got a mixture of sun and clouds with us today, but once again it's the temperature and humidity that's making headlines.  

A Heat Advisory remains in place for much of Connecticut through the day today.

THE REST OF THE HOLIDAY WEEK…

We have one more day of high heat and high humidity.  Under a mix of sun and clouds, expect highs between 90 and 95 inland – this means our heat wave will last another (but final) day!  Heat Advisories have again been posted for today as we expect heat index values to reach or exceed the century mark inland, when factoring in the high humidity (dew point values in the 70s!).  Some relief can be found at the coastline where highs will be in the 80s. 

While today will be dry, tomorrow will feature rain and thunderstorms as a strong cold front moves into the region from the northwest.  This is going to end the heat wave.  It will be a humid close to the week; but highs will only be in the 80s, thanks to the clouds and unsettled weather.  With regard to timing, rain/storms will become likely by mid-morning and last into the early afternoon hours.  Given this is a bit earlier than once expected, the threat for severe weather is not *as* great.  Storms that do develop will produce heavy rain (given the atmosphere is loaded with moisture), in addition to frequent lightning and a gusty wind. 

THE WEEKEND…

Behind the cold front, a comfortable weekend is on tap!  Not only will the humidity be dramatically lower, it will be cooler.  We expect highs near 80 degrees on Saturday, then in the lower/mid-80s Sunday.  Both days will feature abundant sunshine with high pressure in control.

NEXT WEEK…

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, we can’t rule out an isolated shower or storm with highs near 90 inland.  Wednesday, as of now, appears to be partly to mostly sunny with highs in the mid-80s.

NOTABLE HEAT WAVES

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!
