.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
Have removed the fog mention for MRB and CHO this morning as
conditions have trended less favorable. Patchy mid level clouds
are across the area and these should expand into a cumulus field
with daytime heating. An isolated shower could develop near MRB
today, but the low coverage and light nature of any such
activity precludes a TAF mention. Northeast winds should remain
less than 10 kt. There are mixed signals for fog and/or low
clouds for tonight, so will keep those out of the forecast for
now.
High pressure continues to provide VFR conditions Wednesday and
Wednesday night, although winds shift to southerly. Any sparse
convective activity likely remains west of MRB and CHO
Wednesday. A cold front will approach Thursday, and southerly
winds ahead of it may gust to 20 kt. A line of showers and
thunderstorms will likely approach from the west during the
afternoon or early evening. MRB has the highest chance of
thunderstorms, which could be gusty. The line may tend to weaken
or break up as it moves east of the Blue Ridge during the
evening.
Minimal risk for significant weather Friday. Scattered showers
and thunderstorms are possible Saturday.
