.AVIATION /09Z SUNDAY THROUGH THURSDAY/...
Given ample low level moisture beneath a thermal inversion, low
cigs have developed across the northern Alleghenies and Laurel 
Highlands. BFD dropped to IFR shortly after 06z, and will likely
remain IFR through sunrise. Farther to the east, restrictions
have generally been limited to the higher elevation airfields 
north of MDT. High clouds blowing off of convection to our south
has kept fog development to a minimum, but fog may expand if
higher clouds become thinner towards daybreak.

Much of Sunday will be mostly cloudy with MVFR cigs persisting
across central and western airfields through early afternoon. 
A cold front will slide south through the day. Scattered 
SHRA/TSRA are expected along and ahead of this boundary mainly 
during the afternoon and early evening hours, with MDT and LNS 
having the highest chance of seeing vsby restrictions in brief
downpours.

Conditions are expected to improve later Sunday, as the winds 
shift to the northwest and much less humid air moves into the 
area. The HREF does suggest MVFR cigs are possible at BFD into 
Sunday night given upslope flow off Lake Erie. 

Monday and Tuesday look dry at this point with VFR conditions, 
as high pressure builds into the area. Some valley fog is 
possible in the north both mornings.

Outlook...
Wed...PM TSRA moving across from W-E.

Thu...A chance of showers and storms.
