High Humidity and an Isolated T'Storm Threat this PM...

Posted: Updated:


The morning round of heavy rain and thunderstorms produced well over an inch in some spots (1.71 in Hartford!)… now, as of the Noon hour, it’s just warm and grossly humid with dew point values 70 or higher in many spots.

As we head through the afternoon and early evening hours, there is a chance for some isolated storms to pop-up, meaning the coverage should be limited.  Heavy rain will be the biggest threat, in addition to lightning with any that develop.  In a stronger storm, wind could be an issue.

Tomorrow, now looks to be a bit unsettled… isolated to scattered storms can’t be ruled out later in the day.  Regardless, it will be a hot day with temperatures inland approaching or perhaps exceeding 90!  The humidity will also remain up.

Thursday into Friday also continue to appear unsettled with an ongoing chance for rain/storms.  By Friday, high temperatures will likely be in the 70s.

There are some showers out there this morning, so please be careful driving around.  My ride is this morning was tough with very heavy rain and even some lightning in the sky.  There's some ponding on the roadways and you're going to have keep your speeds down.  This rain will come to an end by mid-morning, then most of the day should feature intervals of clouds and sun, along with relatively high humidity.  It will be warm as well, with highs reaching the middle to upper 80s in most of the state.

By later this afternoon and early this evening, the front will be moving through, and that will trigger some showers and thunderstorms across Connecticut.  While not everyone will get a storm, those that do develop could produce heavy rainfall and gusty winds.  For that reason, the Storm Prediction Center in Norman, Oklahoma has put us in the “Marginal Risk” category for severe weather.

Any showers and thunderstorms will come to an end after dinnertime tonight and skies will be partly cloudy.  Temperatures will fall back into the middle to upper 60s by late tonight.



Tomorrow will offer improving weather as the cold front will have cleared the state.  This will bring us partly sunny skies throughout the day.  There will not be much cool air behind the front though, so highs will still reach the upper 80s inland with still elevated levels of humidity.  A few normally warmer locations may even hit 90 degrees tomorrow!  Shoreline locations will be slightly cooler, with high temperatures in the middle 80s.


By Thursday, the front will attempt to return northward towards Connecticut as a warm front.  Eventually it will stall out near or just south of us.  That will bring more opportunities for showers and thunderstorms along with mostly cloudy skies and muggy conditions.  Just how warm we get on Thursday will depend on the progress of the front and how much sunshine we get.  Right now, we're expecting the front to remain to our south, holding high temperatures in the lower 80s in most places.  But if the front makes a little more progress, these temperatures could be several degrees warmer.

Regardless of what happens Thursday, an area of high pressure to our north will push the front back to the south Thursday night.  Then a wave of low pressure will develop along the front and track along it.  That will bring us easterly winds and periods of rain – some of which could be heavy – Thursday night and during the day on Friday.  The rain and onshore flow will keep highs on Friday below average, only reaching the middle and upper 70s!  The normal high at Bradley Airport for July 14th is 85 degrees.

While the models agree that Friday will be cloudy and damp, there is some uncertainty as to exactly how much rain will fall.  The European model is forecasting a soaking rain while the GFS has lighter amounts.  Be sure to stay tuned to Channel 3 Eyewitness News as we fine-tune this part of the forecast!


The high pressure system will build into Connecticut Friday night and Saturday, which will bring an end to the rain.  Partly sunny skies will take hold for Saturday, as temperatures rise from the lower and middle 60s in the morning to the lower and middle 80s by the afternoon.

By Sunday, the high will shift offshore and winds will turn to the south and southwest.  At the same time, a cold front will approach from the west.  This will bring very warm and humid air into Connecticut, with highs in the upper 80s inland and middle 80s at the shore.  It will also bring the chance of showers and thunderstorms for Sunday afternoon and evening.


The front will move off to our east by Monday, bringing mostly sunny skies and lower humidity levels.  Highs will be near seasonal averages, reaching the lower and middle 80s in most places.
