.DISCUSSION...
KEY MESSAGE 1...Dry with seasonable temperatures Saturday. Cooler 
temperatures for Sunday.

A mid-level ridge builds in from the west accompanied by surface 
high pressure which will bring dry conditions and seasonable 
temperatures for Saturday. Highs range in 30s this weekend with a 
spots potentially hitting 40 this afternoon. Saturday night, 
temperatures drop into the teens across the interior and 20s 
closer to the coast. 

Dry conditions continue into Sunday. Model guidance indicates a 
front pushing in overnight Saturday into Sunday from offshore 
shifting winds N/NNE. This will support a cooler day than Saturday 
overall. Cooler air from the coastal waters pushes onshore which may 
end up keeping the eastern coastal areas cooler than inland 
locations. These coastal areas may potentially struggle to get above 
30 degrees while temperatures rise into the low to mid 30s further 
west.

KEY MESSAGE 2...Snow showers remain possible Sunday night through 
the following morning, minor accumulations and little or no impacts. 

Those suffering from snow and/or winter fatigue might be pleased to 
know that a significant winter storm from Sunday night into Monday 
appears unlikely. Though a period of light snow remains possible, 
with limited impacts and accumulations. 

Positively tilted trough moves through the four corners region of 
the Desert Southwest this morning, before reaching the panhandle of 
Texas late this afternoon, developing an area of low pressure over 
the Red River Basin. Guidance remains in good consensus, the area of 
low pressure associated with the southern-stream shortwave traverses 
the deep south, producing locally severe storms, before exiting the 
Carolina coast late Sunday evening. 

As the low pressure system moves northeast over the ocean it likely 
is suppressed by a northern-stream shortwave that is coming out of 
the Great Lakes region. Consensus amongst guidances suggests these 
two features doesn't phase together until late Monday and by then 
the greatest forcing is offshore. With near normal PWATs, do think 
the most likely outcome is a period of snow showers between midnight 
and Monday midmorning. Snowfall and impacts are limited and come in 
two parts. The first part is associated with the northern-stream 
energy with scattered light snow across interior MA. And the second 
part is associated with the low pressure system offshore. Those snow 
showers should be a bit more uniform, though the greatest moisture 
does remain offshore. Again, snow accumulations are low. Perhaps a 
few tenths of an inch of snow, with up to half an inch along the 
south coast of RI/MA and the islands. The 75th percentile is roughly 
1.0" to 1.5" across the islands. There is less than a 25% chance for 
totals to exceed. Maintained 'slight chance' PoPs across interior 
and 'chance' PoPs near the south coast. 

Temperatures warm Monday afternoon into the upper-30s to low-40s 
which will help melt any minor accumulations of snow. 

Key Message 3...Dry and mild on Tuesday, unsettled mid to late week 
with seasonable temperatures. 

Given the prolong cold, it's hard to believe the climatological high 
is around 35F in the interior and 40F for the coastal plain for this 
time of year. Continue to anticipate a warming trend for the coming 
week, with Tuesday being the warmest day. With increasing mid-level 
heights and southwest flow, highs climb into the 40s. Not out of the 
question a few areas may reach 50F as winds shift to the southwest. 
Seasonable temperatures there after through Thursday. High pressure 
moves offshore Tuesday night as a frontal boundary develops across 
the region. Weak areas of low pressure ride this boundary and 
provide unsettled weather Wednesday to Friday. With marginal 
temperatures PType issues are a possibility. This will be something 
to monitor over the coming days.
