HEAT ADVISORIES HAVE REPLACED EXTREME HEAT WARNINGS FOR MUCH OF OUR REGION… HEAT INDICES PUSH 100º IN THE VALLEY TODAY… SCATTERED SHOWERS/STORMS POSSIBLE LATE AFTERNOON TO EVENING
Good morning everybody, I hope you have a Happy 4th of July today and would just say that while plans shouldn’t be cancelled, but you should have a contingency in case a shower or storm does roll over your neighborhood today or this evening.
The most likely to get any more numerous showers or stronger storms is southwest MA and northwest CT, meaning central/southern Berkshires, western Hamsphire, western/central Hampden Counties down into Litchfield and Hartford counties in CT.
In terms of timing, anybody anywhere could see an isolated shower or t-storm generally from late morning through dinner time, but the timing related to the cold front and most activity would be around 6pm to midnight or so, tracking west-northwest to east-southeast.
Again, Heat Advisories have replaced earlier Extreme Heat Warnings as more clouds will develop into the region today, despite our very warm and humid start with temps in the 70s to low 80s already, and dewpoints in the 60s to mid 70s.
These clouds should help keep temps from spiking to the levels of the past 3 days, rising into the mid 80s to mid 90s with lows in the 60s.
We’ll start to clear out late tonight into Sunday morning with a partly sunny day expected tomorrow with highs in the low to mid 80s with less humidity, so for my money, Sunday is the weekend pick, because yours truly is quite sick of these weather conditions – something to look forward to!
Clouds will be building late Sunday, and if trends continue as they have been, I expect a storm system to develop down near the eastern Ohio Valley and track east along the slowing front into the northern Mid-Atlantic region and off the coast to our south for early this coming week.
Assuming that takes place, we could see a beneficial, soaking rainfall push into the greater WMass region, with heavier rainfall totals along and south of the Rt. 2 corridor.
Showers should start Sunday night, and become more numerous and fill in with some embedded thunder on Monday, likely by mid-day through Monday night and into a part of Tuesday.
Lows Sunday night will drop into the upper 50s to mid 60s, and then if this rainstorm does come to pass, highs would only be in the 70s both Monday and Tuesday with lows in the 50s, which means I will be outside in the back lawn (I don’t want to scare anybody in town) and do rain angels for hours as I get drenched, and probably Lyme Disease as well, but these are the sacrifices a Weather Nut has to make, folks, I don’t make the rules!
By mid to late week, we should see that storm clear to the east with warming temps into the 80s for highs, with a few folks hitting 90º by Thursday, along with a few instability showers by Thursday afternoon.
Have a great holiday!

YOUR NUTSHELL:
–Happy 4th of July to everybody
–Extreme Heat Warnings have been cancelled
–Heat Advisories have replaced the Heat Warnings for much of the southern / valley terrain areas of the greater WMass region
–Highs today reach the mid 80s to mid 90s, as the heat wave breaks
–An isolated shower or storm is possible anywhere by late morning through dinner time
–Better chance of scattered showers and thunderstorms, which could produce localized wind damage especially in southwest MA (central/southern Berkshires, western Hampshire, and Hampden County) or northern CT
–Lows tonight dip into the 60s with a few leftover showers or a storm
–Sunday becomes drier behind the cold front
–Highs in the low to mid 80s under partly sunny skies
–Clouds increase late and during Sunday evening as a storm tracks east along the stalling cold front somewhere near the southern New England coast
–Scattered showers push in later Sunday night into Monday morning
–Lows dip into the upper 50s to mid 60s
–Rain is more likely than not to develop, especially south of the Rt. 2 corridor during Monday into Monday night
–Should this storm come close enough, many of us would get a soaking, beneficial rainfall through to Tuesday afternoon
–Highs would only reach the 70s both days with lows in the 50s, which would be quite welcome relief after this heat wave
–Fair weather returns second half of the week with a few instability showers possible by Thursday afternoon with highs in the 80s to near 90º and lows in the 60s
