The Warm, Humid Weather Continues with the Threat for Storms!

Posted: Updated:


Today will be warm and muggy… while there will be a chance for storms again this afternoon, they’ll be more isolated (not as widespread) in nature when compared to yesterday.  Also, they may be confined to primarily the western half of the state.  Heavy rain will be the primary concern with any that develop.

Tomorrow, there will be a slight chance for an isolated afternoon storms… otherwise we just end the week on a warm and humid note.

For the weekend, the forecast is on track:  a chance for rain/storms (some could be strong) as a cold front approaches and moves through the region… behind it, we trend less humid and sunny for Sunday.

It was another warm and humid day across Connecticut today, as high temperatures were in the upper 80s away from the beaches along with dew point temperatures near 70 degrees!

But along with the warmth and humidity came quite a few thunderstorms, several of which have produced Severe Thunderstorm Warnings in northern and western Connecticut.  The main impacts from these storms have been hail the size of quarters and heavy downpours.  According to Doppler Radar, more than 5" of rain fell just to the east of Storrs.  More than 4" of rain fell in portions of Manchester and Tolland.  More than 4" of rain also fell near Cornwall and 2.5-3.0" of rain fell in and around Kent.  This was because of an unstable air mass, loaded with moisture... but there is very little “vertical shear,” meaning change in wind speed and/or direction with height.  Therefore, the storms that developed moved very slowly and largely rained themselves out over the same areas.  


The next couple of days will feature weather similar to what we have seen over the past couple of days.  Highs will rise into the upper 80s inland and middle 80s along the shore while dew points will once again near 70 degrees.  With the instability from the heat and high humidity, both days will feature more chances for showers and thunderstorms, though we do not think they will be as widespread as Wednesday.  The greatest threat will be in northern and western Connecticut tomorrow and Friday, away from the stabilizing influence of Long Island Sound.  Both Thursday night and Friday night will be mild and muggy, with low temperatures between 65 and 70 degrees.


By Saturday, a low pressure system will track into the Great Lakes and drag a cold front towards New England.  That will bring Connecticut more numerous showers and thunderstorms and thus more cloud cover.  There is the potential for some heavier rainfall with some of these showers and storms, but we are not expecting a washout everywhere.  High temperatures will be cooler on Saturday, only reaching the lower 80s in most places.


The front will pass east of us Saturday night and high pressure will build in Sunday.  That means Sunday will be the pick of the weekend, with mostly sunny skies and highs in the lower to middle 80s!  Plus the dew point temperatures will drop into the 50s during the day, so it will feel quite pleasant outside!  Sunday night should be quite comfortable for sleeping, with low temperatures bottoming out in the upper 50s!


The computer models have come into better agreement with regards to the low pressure system that will approach our area late Monday into Tuesday.  Both the GFS and the European model track it eastward towards us.  Monday will start out pleasant, but clouds will increase during the day and rain will likely develop by evening as the system’s warm front gets closer.  The clouds and onshore flow will cap highs in the upper 70s to lower 80s.

Rain may be heavy at times Monday night and will continue into Tuesday morning.  By Tuesday afternoon, most of the rain should taper off, though there will still be plenty of clouds.  Right now, we think that the warm front will get hung up to the south of Connecticut, which would keep us cloudy and hold temperatures in the 70s for Tuesday.  But if the front makes more progress than we are currently forecasting, we could see some breaks of sun and temperatures rising into the 80s.  Be sure to stay tuned to Channel 3 Eyewitness News as we continue to fine tune this part of the forecast!


By Wednesday, the storm will move off to our northeast, turning our winds to the northwest.  That will usher in a dry air mass and allow skies to clear out.  Highs will be quite seasonable, with lower to middle 80s expected.  The normal high at Bradley Airport in Windsor Locks for August 9th is 84 degrees.


This past Monday marked the end of July.  At Bradley Airport in Windsor Locks it was a cool month, with an average temperature of 72.9 degrees… 0.7 degrees cooler than normal.  In fact it was the coolest July at Bradley Airport since 2009, when the temperature averaged 70.2 degrees!  With regard to rainfall, 6.57” fell during the month at Windsor Locks … a surplus of 2.38 inches and the 10th wettest July in the Greater Hartford Area since records began in 1905!

The July weather stats were quite different at Sikorsky Airport in Bridgeport.  The temperature averaged 75.2 degrees… 0.9 degrees warmer than normal, but still the coolest July in Bridgeport since 2009.  The biggest difference between Sikorsky Airport and Bradley Airport in July was regarding rainfall.  Only 2.54” of rain was recorded at Sikorsky Airport, a deficit of 0.92 inches compared to a typical July!
