.AVIATION /04Z FRIDAY THROUGH TUESDAY/...
Showers (and even a few low-topped TSRA near and to the south of
a KTHV to KLNS line early tonight) will evolve into a more
extensive shield of light to moderate rain over about the SE
half of PA late tonight and Friday as an area of sfc low 
pressure over Central Virginia gradually strengthens as it moves
NE along a stalling sfc front. 

A 5-10 kt north to northeast flow across Central PA and the Susq
Valley will transport cooler/moist air into the region and lead
to gradually lowering cloud bases overnight and Fri AM. Bases
will fall through the MVFR range and dip into the IFR Category
for numerous locations Friday morning, before slowly improving
(but still staying MVFR for the bulk of the airfields Friday
afternoon). 

Later tonight and Friday morning, there is high confidence 
(80-90%) in the development of widespread lower clouds and rain.
Ultimately, fuel alternate-IFR restrictions are anticipated. 

Any improvement Fri afternoon would favor the western terminal 
sites (KBFD and KJST), but this won't take place until after 
18z. 


Outlook...
Sat-Mon...Mainly VFR.
