A few showers before the week is over, then a heatwave!

Posted: Updated:
HARTFORD, CT (WFSB) -

AFTERNOON UPDATE...

Today will feature at times filtered sunshine due to some scattered high level cloudiness.  Temperatures should be a bit milder than yesterday, reaching well into the mid if not upper 70s inland.

Tonight, the well discussed coastal storm likely clips southeastern New England… there could be showers that work into eastern CT around daybreak Friday.  The storm then lifts away and we should see a mix of sun and clouds before a disturbance from the west moves through during the afternoon that could trigger some isolated showers or thunderstorms.

For the weekend, the warming trend remains on track that brings us to July or August-like levels.  Saturday, while primarily dry, isolated thunderstorms will be possible late in the day.  Temperatures work into the 80s away from the Sound and the humidity starts creeping up.  Sunday will likely be our first 90 degree day of the month and also will kick off what should be our 2nd heatwave of the year.  Monday and Tuesday, as of now, look to be quite hot with temperatures perhaps reaching into the mid-90s!  Records could be in jeopardy, will need to monitor as we get closer in time as it may come down to a degree or two.  We need 3 consecutive days 90 or higher to have a heatwave, this one could last 4… it will be all about the timing/arrival of a cold front.

TODAY & TOMORROW …

Today will feature a mostly sunny sky with mild temps in the mid to upper 70s inland, and in the lower 70s along the coast.  Later today, scattered mid and high level clouds will be on the increase – at times filtering the sunshine.  This is due to a developing coastal storm to our south.  It appears that the storm is going to clip Southeastern New England late tonight, specifically eastern/southeastern Connecticut.  In those locations we could get some showers very late tonight and early tomorrow morning, but the bulk of the rain will remain well to our east.

With the coastal storm passing by to our east, a northeasterly breezy will be noticeable as we close out the week tomorrow.  During the afternoon, we’ll see another chance for isolated showers or even thunderstorms as a trough moves through the region from the west.  Since there will be more clouds than sun combined with the northeasterly wind, temperatures won’t be as warm as they will be today.  Look for numbers to remain in the low 70s.   

THE WEEKEND AND BEYOND…

The well-advertised pattern change is still on track starting Saturday.  A large “Bermuda High” will develop and create a southwesterly flow, transporting warmer and muggier air into the state. This will bring summer-like weather and even 90 degree heat through early next week. 

On Saturday, a weak boundary may trigger an isolated shower or thunderstorm in the afternoon, but we think most of the day will be dry. Temperatures will reach the mid-80s inland and the upper 70s at the beaches.

Sunday through Tuesday will feature mostly sunny skies along with hot temperatures. We are currently forecasting highs in the lower to middle 90s away from the Sound each day. If this pans out, we will have our second heat wave of the year at Bradley Airport – the first one occurred May 17-19th. Temperatures will be somewhat cooler near the coast, in the mid to upper 80s each day.

A cold front may move through the region late Tuesday, triggering some rain or thunderstorms.  In its wake, temperatures will drop back into the 80s by next Wednesday.
