.AVIATION /06Z THURSDAY THROUGH MONDAY/...
Prevailing VFR conditions are expected at all TAF sites through
Saturday. There's a small chance for some patchy fog prior to
daybreak today, with MRB and CHO standing the greatest chance
for a brief period with fog. If any fog were to form, it would
quickly burn off after daybreak. There's also a very small
chance for a brief shower or storms late this afternoon or
evening. MRB would have the greatest chance, followed by MTN and
BWI, but chances are still to low to mention in the TAFs. Winds
will become northwesterly after sunrise today, turn westerly
toward the middle of the day, and then north to northwest just
prior to midnight as a cold front moves through. Light
northerly winds are expected tomorrow, with light southerly
winds on Saturday.
High pressure remains over the region over the weekend which will
favor VFR conditions across the area terminals. Thunderstorm chances
(20-30 percent) return by Monday which could lead to brief
restrictions during the afternoon/evening hours. Winds should be out
of the south through Monday with gusts increasing to around 10 knots
each afternoon.
