.AVIATION /19Z MONDAY THROUGH SATURDAY/...
The remainder of today will stay generally VFR across the
region. High clouds remain present and will continue to stream
in and lower ahead of the system expected to arrive tonight. A 
widespread snowfall will arrive Monday night into Tuesday as 
low pressure develops and moves up the New England coast Tuesday
afternoon. Confidence in high in visibility restrictions and low
cigs due to snowfall as it spreads from west to eat. Impacts
will begin as early as 05-06Z across the western terminals. All
airfields will likely experience IFR or lower conditions by 12Z
Tuesday morning. This will be a quick hitting storm system, and
precipitation should taper off sometime shortly after 18Z. 

There is a some uncertainty as to where the snow-rain line will
set up late Tuesday morning as temperatures warm up to just
above freezing in the southeast. Currently the only site
expecting to see a rain snow mix will be LNS after 15Z. However,
that transition zone could drift a little further north and some
mixed precipitation could reach MDT before the system moves off.

Outlook... 

Tue...Snow likely with widespread restrictions, before a 
possible mix later in the day across the south. Restrictions 
possible.

Wed-Fri...Trending drier, lingering snow across NW PA.
