.DISCUSSION...
KEY MESSAGE 1...Gradual warmup brings high temperatures from the 50s
to the 60s and 70s Thursday and Friday as the prolonged dry stretch
continues. Windy conditions arrive Friday ahead of a weak cold
front.
Cold start to the day today as efficient radiational cooling has
brought some of the coldest air of the season to the region. Lows
have ranged from the lower 40s across urban areas to the lower 20s
in the valleys of northern Massachusetts. Should see temperatures
rebound fairly quickly by the early morning under full sun. Still,
it will be somewhat cool today with high temperatures in the mid 50s
in the interior and near 60 across the lower CT River Valley. Warmer
lows Wednesday night as mid and high clouds overspread the region
during the first half of the night. A more narrow window of clearing
through the second half of the night will likely result in lows
running about 5-10 degrees warmer.
Expecting a rebound in higher temperatures Thursday as a surge of
warm advection ahead of a cold front warms 925 mb temperatures to
between +11 and +15C.This will yield high temperatures in the mid-
60s on Thursday with a few isolated readings near 70 in the
Connecticut and Merrimack River Valleys. Despite the mid-level
zonal flow Friday (ahead of our next weak wave), the westerly flow
will support efficient mixing in the boundary layer. This will
result in a gusty/windier day and likely the warmest day of the week
with high temperatures in the upper 60s to low 70s. Some of the
strongest gusts will likely be found downwind of the Berkshires with
a favorable wind direction for downsloping and thus locally
higher gusts. NBM continues to highlight probabilities 50-75%+
for temperatures 70F or greater with the highest probabilities
for the valleys and I-95 metros. This is reasonable given the
added factor of the warming downslope flow. A mild late-October
day is looking likely.
Another moisture-starved shortwave and cold front moves overnight
Friday. This will shift temperatures back into the lower 60s this
weekend, which is seasonable for late October.
KEY MESSAGE 2...Transition to a more unsettled weather pattern by
early next week bringing periodic chances for rain. Confidence
in specific timing remains low.
Looking ahead to next week, ensemble continues to show a rather
chaotic upper level pattern unfolding across the CONUS. A deep
trough digs over the western US as a series of embedded shortwaves
eject into the plains and track E. Guidance shows a wide range of
solutions with the eventual tracks of these systems as they approach
the region early next week. Many factors, namely the extent and
magnitude of upper level confluence will govern the strength and
track of any eventual storms. At the moment, think the NBM has a
good handle on POPs Sunday night into Tuesday with probabilities
increasing to between 20 and 45 percent.
