.AVIATION /09Z MONDAY THROUGH FRIDAY/...
Light rain continues to push eastward across Central PA, with
the back edge of the steady precipitation approaching BFD and 
JST as of 06Z. A wide range of conditions have been reported as 
the rain moves through ranging from VFR to LIFR. While most 
guidance would suggest that IFR will be most likely through the 
rest of the night, continued fluctuations in ceilings and 
visibility are expected. 

Dense fog has started developing over Ohio and western 
Pennsylvania behind the rain, and this will likely expand into 
at least some of the forecast area over the next few hours as 
the rain begins to exit to the east. The best chance for fog
appears to be at BFD and JST, though it is certainly possible
that visibility could drop lower than what is currently shown in
the TAFs for the other sites as well.

Expect gradual improvement from northwest to southeast during 
the late morning and afternoon as flow becomes northwesterly,
ushering in a drier airmass. VFR conditions should return area-
wide by 20Z. A few showers are possible during the afternoon,
but we will keep any mentions of rain out of the TAFs for now.

There is some signal for fog to develop across parts of the 
area Monday night, but confidence is low on restrictions at any 
TAF sites. There is also a low chance (around 30 percent) that 
low clouds move into southeastern PA as a quasi-stationary 
boundary attempts to lift northward. This would most likely 
impact MDT and LNS.

Outlook...

Tue...Possible morning fog, then VFR.

Wed...Mainly VFR, some scattered SHRA could bring restrictions.

Thu-Fri...Mainly VFR, skies mostly clear
