Good afternoon folks, while we’ve seen severe thunderstorms form in westernmost CT a little earlier this afternoon with wind damage reported in Litchfield County, we’ll be mostly hot, humid and rain-free for the rest of the evening until about midnight when a shortwave will likely push another round of showers and night-time thunderstorms into our region.

Lows will only hang around 60s with continued humidity, so it will be a muggy, summery night, even after overnight showers/storms are cleared to the east.

For Friday, another frontal boundary will some drier air behind it will approach the region late in the afternoon and evening with some scattered showers and thunderstorms, some of which may be strong well west of the I-91 corridor like today’s were in northwest CT.

Highs will soar into the mid 80s to mid 90s and with dewpoints well into the 60s to low 70s, heat indices will push into the mid 90s to low 100s, and Heat Advisories have correspondingly expanded throughout much of the greater WMass region except for perhaps the northern Berkshires and western Windham County in VT where the higher mountains will keep us cool-er enough in those locations.

Lows Friday night will dip into the mid 50s to low 60s behind the front, and humidity will start to decrease into Saturday which looks quite nice, but still very warm with highs in the upper 70s to upper 80s under mostly sunny skies, with lows in the 55-60º range.

For Sunday, a southwest flow will keep us very warm to hot with highs well into the 80s to low 90s for some in the valley as humidity tries to creep up a bit.

By late in the afternoon and evening, we’ll see a stronger cold front approaching the region. Unlike our high-instability, low wind-shear setup today/Thursday (which will be similar tomorrow/Friday), Sunday evening’s set up will feature higher wind shear and a bit less instability, with the higher shear helping to better organized broken lines of thunderstorms.

Some of these storms would produce localized straight line wind damage with the incoming forcing of the cold front (cold fronts bulldoze through warm, muggy air and send it skyward, creating thunderstorms if enough moisture is present).

The timeframe is subject to change, but right now it looks to be about 4-9pm, but I will update my channels over the weekend.

Lows Sunday night behind the front will drop to about the low to mid 50s, which will be followed by a more seasonable and tolerable early-Summer pattern which looks to last into the following weekend, based on current upper-level guidance and charts.

Highs on Monday will hang in the upper 60s to upper 70s under mostly sunny skies with lows in the upper 40s to mid 50s for a chilly morning dog walk early on Tuesday!

The Tuesday through Thursday timeframe should rebound a bit, but mostly hang in the mid 70s to low 80s for highs with some showers possible by Wednesday, with no big washouts or severe weather outbreaks anticipated.

I will update again in the morning, and hope you have a great evening, Dave.
