Aviation Forecasts and Information Page - NWS State College PA

.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
Periods of rain and showers will continue primarily across the 
southern 2/3rds of the Commonwealth through Tuesday night, with
areas of -RA/RA this morning trending towards -SHRA in the 
afternoon/evening as high pressure gradually builds in across 
the Northeastern US. 

A period of prevailing MVFR restrictions is
likely across all terminals, especially through 18Z Tuesday, as 925
mb RH values approach 100% along a NW-SE gradient. Periods of 
IFR to briefly LIFR are most favored across the south-central 
mountains (KJST/KAOO/KUNV) where easterly sfc flow across 
terrain + steadiest rainfall look to overlap. 

The quickest improvements to VFR are most likely at KIPT around
18Z Tuesday as drier air filters in from the northeast, with 
improvements to VFR occurring elsewhere Tuesday night and 
perhaps into Wednesday morning (mainly KJST/KAOO, farthest from
the moisture gradient, and perhaps KMDT/KLNS as well).


Outlook...

Wed-Thu...Trending VFR across central PA, with slower 
improvements possible over the Laurels and Lower Susquehanna
Valley where -SHRA/BR and low cloud ceilings may linger.

Fri-Sat...VFR favored as a developing coastal low looks to 
bring subsidence overhead, though -RA and lower cloud ceilings 
associated with this system may reach our eastern terminals.
