.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
Not much change for the 00Z TAF set.

There could be isolated tiny snowflakes at times overnight, 
some indication of this on the radar returns on the MD/PA 
border as of 5 PM. MVFR to IFR CIGS across the entire area
as of 5 PM as well, not seeing much change in conditions
overnight. CIGS will trend to lower with time, before 
improving later on Sat.

See earlier information below on the potential for very light
freezing drizzle with the lower CIGS over the higher terrain.

Earlier information below.

Widespread MVFR to low end VFR stratus covers all of the 
Central PA the mid afternoon hour. Ceilings will lower to 
IFR across most of central PA during the evening and overnight.

Once IFR ceilings develop, they will likely persist at BFD, 
JST, and LNS through 12Z Sat. The other sites may see ceilings 
rise to MVFR before sunrise Sat.

Some patchy light freezing drizzle is possible late today
through early Sat where cloud bases lower to within 500 feet or
so of the ground (which will occur mainly on the ridge tops). 

Outlook... 
Sat...Restrictions possible, chance of snow showers in the NW 

Sun...A compact but more amplified upper level trough with a 
preceding low level south to southwesterly wind max will likely 
bring a 4 to 6 hour period of mainly light snow with IFR vsbys 
and MVFR to IFR CIGS (targeting mainly central and northern PA) 
late Sunday/Sunday night. 

Mon...Mainly VFR

Tue...Snow/restrictions possible mostly in the second half of 
the day
