.DISCUSSION...
KEY MESSAGE 1... Mostly dry with above normal temperatures
continuing through the weekend with humidity on the decrease.
Temperatures remain in the upper 80s to low 90s through the
weekend as an unseasonably warm airmass remains draped over New
England. However, there will be a noticeable difference in the
"feels like" temperatures compared to the last few days as
dewpoints drop to the mid to upper 50s in the wake of a cold
front pushing offshore this morning. With a ridging pattern
moving into place aloft, expecting conditions to remain dry
through most of Sunday.
KEY MESSAGE 2...Expecting showers and thunderstorms Sunday
night with the risk for severe weather remaining low.
A cold front pushing into Southern New England Sunday night
will increase the risk for showers and thunderstorms.
Instability likely remains low heading into the overnight hours,
despite elevated shear magnitudes, which will help to mitigate
the risk for storms to turn severe. Uncertainty still remains in
rainfall totals, with the latest suite of guidance indicating
2.0"+ PWATs could stretch anywhere from DelMarVa to Portland,
ME. The ECMWF is the most aggressive, bringing 2.0-2.15" PWATs
along the entirety of the I-95 corridor, but the GFS and
Canadian guidance keep that deep moisture further south across
Long Island. The latest round of ensembles and AI ensembles
continue to keep the worst PWATs off our southern waters;
however, there is a noticeable northward trend from run-to-run.
Certainly something to keep an eye on as the day progresses.
KEY MESSAGE 3...Seasonable temperatures and lower humidity
returns through the first half of next week before a return to a
more active pattern late-week.
A cooler and much drier airmass then works into Southern New
England Monday into Tuesday. Latest guidance shows 850 mb temps
now dropping to around +8 to +10C, some 5-7C lower than we've
been seeing. Highs are likely to drop into the low 80s, with
dewpoints plummeting into the mid 40s to mid 50s, bringing about
much more comfortable "feels like" temperatures. Temperatures
will start to climb again heading into Wednesday, but are still
seasonable in the low to mid 80s with still tolerable humidity
levels.
More active weather looks to develop around Thursday or
Thursday night, as a stronger disturbance aloft moves in and
sweeps a cold front through Southern New England. This could
bring a better shot at showers/storms, although it's still too
early for specifics at this timeframe.
