.KEY MESSAGES...

- Cloudy and unsettled start to this workweek as multiple weak
  disturbances pass by.

- Cloudy through midweek with more seasonable temperatures.

- Unsettled weather may return late this week.

.DISCUSSION...
KEY MESSAGE 1...Cloudy and unsettled start to this workweek as 
multiple weak disturbances pass by.

We remain under WNW flow with another upper level trough clearing 
the region later tonight, and with it cooler temperatures
prevail aloft. Add in a passing mid level shortwave as well, 
and there is a risk for isolated to scattered light showers 
today, especially from late morning in to this afternoon. The 
risk for showers diminishes towards sunset. The greatest risk
will be towards the higher terrain of western MA.

Breezy west to northwest winds into Tuesday as colder air moves
into southern New England.

Drier weather should prevail tonight and Tuesday. Temperatures
expected to be closer to normal as well.

KEY MESSAGE 2...Cloudy through midweek with more seasonable 
temperatures.

Another trough passes over the region Tuesday night into
Wednesday morning, along with an associated surface low to our
northeast, continuing the WNW to NW flow expected for the start 
of the week. 850 mb temperatures return to just below 0C for
most of the region as well before improving slightly once more
Thursday ahead an approaching strong closed low. 925 mb
temperatures generally remain around 4-6C during this midweek
period. These conditions will continue supporting more
seasonable temperatures with highs in the 50s and lows in the 
30s and 40s.

KEY MESSAGE 3...Unsettled weather may return late this week.

Towards the second half of next week, guidance has continued to 
indicate possible development of another low pressure
originating from just to the south of the region along/just off 
the mid- Atlantic coast. This looks to be driven by a multitude 
of factors, starting with a trough developing off the Rockies by
sometime Tuesday night/evening that will track eastward. As it
does, ridging amplifies over the western CONUS and sets up over 
the Rockies by sometime Wednesday. The trough from the Rockies 
then may end up phasing with trough energy from the Canadian
Prairies, which then tracks southeast, deepening into the Ohio
Valley. This solution has started to become the main consensus
even among the deterministic global guidance. Surface low
pressure develops over the mid- Atlantic, then tracks northeast. 
Past this point midweek though and closer to the surface,
details become more uncertain.

A lot of spread remains this far out regarding its track and
what the potential impacts to southern New England could look
like. 00Z GFS and GEFS guidance continues to favor a warmer,
wetter solution as the low would track moreso directly over the 
region, with the colder air aloft not coming in until sometime 
Saturday morning. This would keep precip over much of the region
as mostly rain, with a changeover to gloppy, wet snow possible 
towards the eastern slopes of the Berkshires and over the higher
elevations of the Worcester Hills. At this time, this is not 
expected to be greatly impactful if this scenario is what pans 
out. Other guidance (ECMWF, Canadian suites) indicates a decent 
bit of colder air aloft, notably 850 mb temperatures below 0C, 
approaching the region a bit earlier, but the center of the low 
tracks closer to the 40N/70W benchmark, which would keep the 
region drier. Given the multiple facets associated with this 
potential system, more should become clearer as the details 
developing earlier this week come into focus.

Once this potential system pulls away, we're left with cyclonic
flow aloft, leading to cloudy skies and cooler temperatures
(especially as 850 mb temperatures look to fall to around -4C). 
Breezy NW winds look to take hold as well as more northerly to 
NW flow sets up over the region.

gusting to 20-25 kt, especially for the higher elevations. Winds
W becoming more NW through this afternoon. Gusts briefly
diminish tonight, before increasing once more Tuesday morning.
