.SYNOPSIS...
Not as hot in southern New England today, those in far
northeast Massachusetts will have the most relief, while the
lower Connecticut River Valley remain warm. Temperatures will
continue to trend cooler on Thursday, before rebounding Friday
through the upcoming weekend. As we enter a summery pattern, a
daily chance for showers and storms remain a possibility today
through Friday, with signs of drier conditions for the upcoming
weekend, then followed by more unsettled conditions early next
week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Update: 435AM
Key Messages:
* Scattered showers particularly through mid-late morning north
of the MA/CT/RI borders
* Cooler across eastern and northeastern Massachusetts, though still
seasonably warm across interior southern New England.
* A few isolated thunderstorms are possible this afternoon.
Cluster of showers will impact many locations through mid-late
morning with the bulk of these north of the MA/CT/RI borders
with an abundance of moisture and some shortwave energy too.
This afternoon it`s noticeably cooler across northeast Massachusetts,
where highs struggle to hit the middle and upper 70s, this including
Boston. Moving inland and westward, away influence of the North
Atlantic Ocean, highs are seasonable reaching the lower 80s, while
the Connecticut River Valley stands the greatest chance of reaching
the upper 80s. Have opportunities for storms today, though not to the
extent experienced overnight. Forcing isn`t great, weak surface low
and a mid-level shortwave might be enough to pop isolated
thunderstorms. In addition, PWATs are still elevated, 1.8" to 2.0",
thus any storms could put down torrential downpours. Do have a
marginal risk of excessive rain, per WPC.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
Tonight: Unsettled conditions remain overnight, scattered showers
and thunder. Mainly cloudy skies will lead to a mild night with lows
in the middle to upper 60s, while urban areas hold steady around 70F.
Thursday: A quasi-stationary front settles over southern New England
and will be a source for showers and storms during the day. Timing
is early to mid-afternoon through the early evening hours, though
there is lower confidence in exact location of these storms given
the convective nature. SPC does have a Marginal Risk for severe
storms, but it was mentioned in their discussion, if confidence were
to increase in the areal coverage, part of the northeast could be
upgraded to a slight risk. Area at the greatest risk are western
areas of MA & CT, where daytime heating will be more robust, getting
into the low 80s, while eastern areas are in the low to middle 70s
due to the easterly flow off the cooler ocean. Also, there is still
a low risk for excessive rainfall per the WPC ERO, which kept the
region under a marginal risk ~ PWATs are roughly 1.5" to 2.0" thus
any storms could put down torrential downpours.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Not much change to the overall synoptic pattern into Friday. Still a
risk for some showers and thunderstorms Friday. It`s likely Saturday
is the day which features the lowest chance for showers. Even Sunday
should be dry most of the time, with the risk for some showers and
thunderstorms late in the day. Have low confidence in the forecast
details early next week. Too much uncertainty with the timing of
potential showers and thunderstorms.
