.AVIATION /01Z SUNDAY THROUGH THURSDAY/...
For the 00Z TAF period, flight restrictions will be possible due
to overnight fog (mainly across the Allegheny Front/Plateau for
KBFD/KJST/KAOO, with localized fog with lower coverage possible
around KMDT/KLNS downwind of the Chesapeake) and due to 
scattered showers/thunderstorms tomorrow afternoon (primarily 
along and downstream of a north-south oriented sfc trough 
situated near KUNV/KMDT/KLNS/KIPT tomorrow afternoon).

Spotty showers have developed along the sfc trough which will 
slowly continue eastward through tomorrow, with localized flight
restrictions possible (20-30% chance) but not prevailing.
Increasing moisture via light southerly flow will promote
overnight fog development across the Allegheny Front/Plateau
(mainly KBFD/KJST/KAOO), with lower confidence in fog
development at KUNV/KIPT. A secondary moisture axis around 
KMDT/KLNS, where southerly flow may bring enhanced moisture 
from the Chesapeake Bay, may result in localized overnight fog
in this area as well, with lower confidence in visibility
restrictions at the terminals.

Overnight fog will mix out during the morning hours on Sunday,
with prevailing VFR expected regionwide outside of any
afternoon/evening showers/storms. Garden-variety, isolated 
instability showers are possible across the area, though
shower/storm activity will mainly be focused around the north-
south sfc trough over central PA, around KUNV/KMDT/KLNS/KIPT.
Visibility restrictions from heavy rain would be the primary
impact, though gusty winds primarily around 15-20 kts with
variable wind direction may occur as well.

Outlook...

Mon...Restrictions likely in afternoon -SHRA/-TSRA. Patchy
overnight fog possible.

Tue...Restrictions likely with scattered -SHRA/-TSRA.

Wed-Thu...Restrictions possible as -SHRA/-TSRA becomes less 
numerous. Patchy overnight fog possible.
