.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
A mix of MVFR and IFR restrictions are being observed this
morning across Central PA. While ceilings have been slow to
lower across the region, the expectation is still that IFR
conditions will develop at all airfields within the next few
hours. Once they do, most guidance suggests that IFR will
persist through the end of the TAF period. The exception will be
at JST and maybe AOO where a period of MVFR ceilings will be
possible this afternoon. There is even a low (less than 30
percent) chance that JST sees a brief period of VFR conditions.
Any improvements will be short lived as ceilings will return to
IFR/LIFR across the entire forecast area tonight.
A relative minimum in shower activity is expected this morning
and into the afternoon, but rain becomes more widespread once
again this evening over western PA. This shower activity will
spread eastward into the overnight hours, eventually reaching
all TAF sites. Some weak elevated instability will be present
as these showers move in, so a few rumbles of thunder cannot be
completely ruled out.
Outlook...
Mon...IFR/MVFR early, then MVFR in light rain showers
Tue...Possible morning fog/low visibility, then VFR.
Wed-Thu...Mainly VFR, some scattered SHRA could bring
restrictions.
