.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
As sfc winds diminish this evening, LLWS will become a concern 
again at MDT and LNS with winds between 1500 and 2000 feet
remaining in the 40 to 45 knot range for much of the night. 
Expect ceilings to lower from northwest to southeast through the
night and into Wednesday morning as rain expands southeastward 
along a cold front. IFR ceilings will first develop at BFD 
before expanding to JST and AOO by mid- morning. Both the LAMP 
and the NBM would indicate that IFR ceilings will develop across
the rest of Central PA as well, but model RH profiles from both
the RAP and HRRR suggest that MVFR ceilings are more likely. 
This is supported by the HREF as well, which only shows a 20 to 
50 percent chance IFR ceilings impacting any other TAF sites. 
Visibility will likely drop to MVFR as rain moves in, with 
periods of IFR visibility possible. 

Steady rain will begin to taper off from west to east during the
morning and afternoon hours, though showers could linger into 
the early evening in the southeast. Much of the day will bring 
MVFR or IFR ceilings. The cold frontal passage will take place 
as early as 12z at BFD, and then the front will very slowly 
slide southeastward, finally making it to LNS around/after 00z 
Thu. 

Outlook...

Thu-Fri...-SHRA possible, but trending drier.

Sat...Restrictions possible in rain.

Sun...Showers and thunderstorms in the afternoon with
restrictions possible.
