.DISCUSSION...
KEY MESSAGE 1...Snow gradually exits the region early this morning. 
Mainly dry for rest of today and Thursday with the exception of a 
few light snow showers. 

The clipper system is expected to exit the region early this 
morning, ending the bulk of the snow/wintry precipitation generally 
from west to east between 1-7 AM. Dry air moves into the upper and 
mid-levels (DZG) tapering off snow rates while the system shifts 
offshore. Still can't rule out patchy freezing drizzle/snizzle for a 
brief period early this morning if moisture ends up lingering in the 
low levels.

Mainly dry conditions expected for the rest of today. Drier air and 
cold advection will allow for mixing of gusty NW winds to the 
surface today with gusts 20-30 mph. We'll tap into some mid-level 
moisture off the Great Lakes toward the afternoon which will bring 
in cloud cover. NW winds may favor some upslope for the Berkshires 
for light snow showers. A few showers may make it over on the east 
side with a coating at most.

Thursday AM, an inverted trough tied to a departed surface low 
shifts south across the southern New England coastal waters. This 
will provide a brief period of ascent to support light snow showers 
mainly for the outer Cape, but potentially brushing Cape Ann. Model 
guidance continues to show more of an offshore brush with higher 
probabilities for a light accumulation of snow confined to the outer 
Cape. Model soundings show a period of modest lift/moisture within 
the DGZ. Enough to support a light accumulation (< 1") of snow 
Thursday morning. 

KEY MESSAGE 2...Quiet pattern overall with periods of nuisance light 
snow and minimal impacts. Temperatures moderate to near seasonable 
norms. Attention turns to the late weekend for a potential coastal 
storm, but forecast confidence remains low due track uncertainty. 

Surface high pressure builds across the eastern CONUS into the end 
of the week, maintaining seasonable temperatures. An upper-level low 
and northern-stream shortwave cross New England Friday night into 
early Saturday, bringing a low (<30%) probability of snow showers to 
southern New England. This remains a moisture-starved system with 
PWATs below climatological normals, though minor accumulations are 
possible across the higher terrain of northern and western 
Massachusetts. Tranquil and seasonable conditions are expected for 
the upcoming weekend as high pressure remains dominant. 

Looking ahead, guidance continues to signal for a robust mid-level 
shortwave to cross the Texas panhandle with development of an area of 
low pressure across the Red River Basin by Saturday afternoon. Where 
this feature moves toward is uncertain. The last couple of days, the 
models have suggested it moves off the Carolina coast, strengthens, 
and possibly becomes a significant coastal storm for our region. As 
mentioned last night, predictability remains low at this range. 00z 
ensemble guidance depicts a wide variety of solutions, GFS ENS would 
have this surface low move towards the Gulf Coast. ECMWF ENS depicts 
a large clustering off the Carolina coast, many of the members are 
out to sea and south of the bench mark. Though a small number of the 
members pass very close to the bench mark. Similar, but not as 
robust is the CMC ENS. UKMET has backed off, with a shift towards an 
track out to sea. And for good measure, the deterministic AI runs of 
the GFS and ECMWF have a solution of out to sea. Opt'd for low-end 
POPs Sunday night into Monday due to uncertainties. At this time, 
confidence in any impacts remains low, though the system bears 
monitoring.
