Good morning everybody, as Ringo Starr says in the new Beatles: Get Back trailer, “another bright day”, except it’s not super bright for many of us this morning, thanks to weak low pressure to our south east of the Jersey coastline.
This has thrown some lighter showers northeast into northern CT and parts of southern WMass and CMass, and a few more possible through the morning, though we’ll see that activity lessen with time.
It’s mild with temps in the upper 60s to mid 70s, and highs today will reach the mid 70s to mid 80s from high terrain to the valley floor, and humidity will be present with dewpoints in the 60s.
By afternoon, we’re going to see what is called a differential heating boundary form, due to the cloud deck over a good portion of WMass and especially east of I-91 in NH, MA and CT with more partly sunny skies west of there (Litchfield County is already seeing sunshine break through at 8:30am for example).
This will focus an area of rising air, and with generally lower than average pressure aloft slowly pushing east and into the region, both of those factors will allow for the development of scattered showers and thunderstorms this afternoon, especially along and north of the Rt. 2 corridor in northern MA, southern VT and southwest NH.
There is very little wind shear or wind to speak of today, so any storms that do form will tend to produce heavy rainfall with very localized street flooding potential, but no strong wind is anticipated. Perhaps some small hail will be seen in one or two cells.
This activity will wane tonight with low temps in the low to mid 60s, but the upper low to our south will spread some lighter showers north and into parts of our region overnight and into early Monday morning.
For Monday, one more warm (but not hot) day arrives, with highs in the upper 70s to low 80s as the low to our south delivers its final waning influence on our skies, with mixed clouds and sun, and a spot shower possible. Lows will dip into the mid 60s as clouds increase and a warm front approaches.
For Tuesday, the humidity surges (see attached dewpoint animation chart), with dewpoints cresting 70º for some of us, and highs rising into the 85-90º range with an isolated shower or thunderstorm in the afternoon possible. Lows will be warmer, holding in the mid to upper 60s with a storm possible at night as well, but nothing severe expected.
Wednesday through Friday is when the Bermuda high setting up over the western Atlantic, along with a trough to our northwest both combine to pump heat and humidity into the region for a resurgence of Summah!!

Hot and humid, with highs in the mid 80s to mid 90s from the high terrain to the valley floor will prompt Heat Advisories for part of our region, and a heat wave will result for some by week’s end.
Dewpoint temps will rise into the upper 60s to mid 70s, so it will be oppressively humid during this timeframe.
Each afternoon will feature potential for scattered showers and thunderstorms, with torrential rain in some.
Finally, I will be watching for Air Quality issues, and fine particulate smoke impacts from western wild fires.
In general, between the heat, humidity, and smoke potential, those with respiratory or other health issues, or those who work outside, should prepare in advance for the Wed-Fri period as it could combine to be the most impactful period on the body weather-wise in a while (save for that super smoky day which was horrendous).
By Friday evening, a cold front moves through the region, and that is when we have to watch for strong to severe thunderstorms with wind potential, or hail.
By next weekend, we will dry out and cool down and this should last through at least Monday, and likely into Tuesday as well.
