Good morning folks, we’re starting out with some patchy dense fog out there, notably in the Berkshires, eastern Franklin County at Orange and parts of southwest NH, to name a few.

We’ll be dealing with heat and humidity through at least Tuesday at this point, and possibly Wednesday with afternoon isolated shower/storm chances, a bigger rainfall potentially as the cold front comes through mid week, and cooler, more refreshing Canadian air by late week, but before we dive into all of the weather details below, let’s check a note from our new local weekend sponsor, Yankee Mattress Factory based in Agawam, MA.

***DHTWN DAILY WEATHER REPORT***
——————————————-
Good morning everybody, our Bermuda High pressure system is still in place over the western Atlantic Ocean, and with clockwise flow around it, you can imagine it driving hot and humid air up along its western flank, into New England.

The flow direction is southwesterly (meaning southwest to northeast directionally), and over land, which helps keep the heat quite humid and, well, hot.

So for at least the next three days, we’re going to be soaking in it, as Madge from the 70s & 80s Palmolive TV commercials used to say.

Beyond that, we have to resolve the timing and impacts from a slow-moving yet steadily incoming cold front which will eventually change out this soupy air mass for a much drier and comparatively cooler one by late next week.

It’s that Tuesday to Thursday timeframe that carries high uncertainty for now, so it’ll be tough for me to answer many questions about that period, as we just don’t know yet about how a Canadian trough well north along with the Bermuda high way south will ebb and flow, and ultimately determine how the cold front develops and tracks.

So for now, let’s get into the dailies!

For today, it’ll be hot and humid, with Heat Advisories hoisted for SVT (except western Windham County VT), the southern Berkshires, and northwest CT (Litchfield County) with heat indices into the mid 90s or so expected.

High air temps will reach the upper 80s to low 90s for most of us, with a few mid 80s up in the southern Green Mountains, and some mid 90s possible in the southern CT River Valley.

Isolated afternoon showers or thunderstorms will flare up, drift slowly, and wax and wane until sunset, when they will die down and abate. Lows tonight will be in the upper 60s to low 70s with patchy fog late. Most will remain dry.

For Sunday, it’s rinse and repeat.

However, it may be a touch hotter, but you get the idea. Heat indices each day push into the mid to upper 90s to near 100º with air temps in the upper 80s to low 90s with a few spots a tad cooler and a tad hotter.

Mostly sunny skies are expected for the weekend, with more isolated showers/storms Sunday afternoon, which will flare down at night and beget patchy fog late, with lows either side of 70º #BrokenRecord

As of now, Monday looks like it could be the last day of this prolonged heat wave with similar highs to this weekend (mid 80s to low 90s or so, and afternoon isolated showers/storms that die off at night).

However, there’s a chance that this heat may last into Tuesday, depending on the timing of an incoming cold front.

This front will be moving slowly by the Tuesday/Wednesday timeframe, and should help to focus more numerous showers and thunderstorms across the region by mid-week #HeresHoping

But by as early as Tuesday, and as late as Wednesday, heat should break while humidity remains, with highs in the low to mid 80s both of those days.

By Thursday into Friday, that front should be through the region, with deliciously-lowered dew points into the 50s arriving as dry air pushes the Bermuda High out to sea, and is replaced by Canadian high pressure to our northwest.

Highs would likely be in the upper 70s to low/mid 80s with lows either side of 60º.

A NOTE ABOUT RAIN IN THIS PATTERN: Folks, most people are going to be dry through this period.

This not a drought-denting pattern, it’s a summer convective pattern that produces these small-area showers and storms, so if you get some rain, it’s a bonus, because many will not, unfortunately.

There could be a coastal storm by late next week, though it may be an out-to-sea tease, bringing beneficial rains to Nova Scotia but not New England.

I will update you on all of it as it comes, because if you haven’t noticed lately, we’ve always got weather floating through our lives (both outer and inner, for that matter).

Have a great day and stay hydrated through this stretch!
