.AVIATION /07Z THURSDAY THROUGH MONDAY/...
Some fog is beginning to develop across northern PA and IFR
ceilings have developed at IPT. Expect continued expansion of
the fog through the rest of the night, with BFD and UNV having
the next highest chance of seeing IFR cigs/vsby at some point
tonight. Confidence in fog formation is lower at the other TAF
sites.
A swath of steady rainfall will overspread central PA this
morning, with KUNV/KIPT looking to be within the core of this
swath (meaning higher confidence in MVFR-IFR visibility
restrictions), with KBFD/KJST/KAOO more-so on the periphery
(more intermittent MVFR-IFR restrictions, especially where rain
is more showery). Rain at KMDT/KLNS looks to be more
showery/convective in nature, with a few strong to severe
thunderstorms possible in the afternoon. Rumbles of thunder may
occur in the steadier, more stratiform swath of rain where
MUCAPE may rise to 100-250 J/kg (primarily KUNV/KJST/KAOO).
Winds will tend to be variable near the system's track over
southern PA, with winds generally N/NE north of the system &
S/SE to its south. Cloud ceilings lower to MVFR-IFR later
during the afternoon and evening in the vicinity of the low
pressure center, with low stratus and/or fog possible overnight
as low-level moisture persists while mid/high clouds clear out
and winds lighten.
Outlook...
Fri...AM fog, otherwise trending VFR.
Sat-Sun...Scattered to numerous showers/t-storms likely. Breezy.
Mon...VFR returns for early next week.
