.DISCUSSION...
KEY MESSAGE 1...Dry & seasonable weather continues through mid-week
with a good amount sunshine. Temperatures range from the the 30s-
lower 40s overnight to upper 50s in the afternoons.
Dry westerly flow continues through the middle of the week under
zonal flow at the mid levels, sandwiched between a surface low over
eastern Canada and high pressure over the southeast U.S. Not much
change in the airmass overhead with 925 mb temps in the 6-8C range
Tue/Wed. Some lingering moisture in the mid/upper levels moves
through early leading to increased cloudcover this morning, but
drying out/clearing up by the afternoon with plenty of sun. This
continues Wednesday though we'll start to see some
moisture/increasing cloudcover filtering in later in the day
Wednesday. Altogether, should see high temperatures each day topping
out in the mid to upper 50s.
KEY MESSAGE 2...Monitoring another storm Friday, although there
remains high uncertainty in exact timing and storm track.
The latest round of ensemble guidance continues to show large
uncertainty in the development of a potential storm as we head into
the late week/weekend, especially within the track of the low. While
all guidance continues to indicate paths anywhere from Maryland to
Nova Scotia, the ECMWF and Canadian ensembles (and their AI
ensembles) have trended towards the 40N/70W benchmark or slightly
south while the GFS ensemble shows tracks closer towards the
southern New England coast. Despite the uncertainty in track, most
guidance has indicated the low deepening into the mid 990mbs by
early Friday morning as well as 850mb temperatures dropping to below
freezing across southern New England by Friday evening, supporting
chances for some snow to mix into the region Friday and Friday
night across the higher elevation regions.
Probabilities continue to indicate only a 30-50% chance for 1"+ of
snow in the higher terrain, with the highest chances along the
eastern slopes of the Berkshires, and less than 20% probability for
3" or more. As mentioned by previous forecasters, those probabilites
assume a 10:1 snow to liquid ratio, and unless we get really heavy
precipitation rates (highly unlikely), those 10:1 SLR accumulations
would likely be lower with wetter snow characterization being more
favored. Any winter weather impacts in the higher elevations are
likely to be very limited to nil, and this is reflected by low
probabilities of Minor winter storm impacts in the Probabilistic
Winter Storm Severity Index.
Heading into the second half the weekend, the low will push further
into Atlantic Canada and high pressure begins to build over the Mid-
Atlantic region, bringing a return to blustery and dry conditions to
southern New England for the start of the next work week.
