.DISCUSSION...

Cold and blustery conditions, with gusts of 30-35 mph, are
expected today. Afternoon RH values will drop to around 30 to 40
percent, especially across central Virginia from the Shenandoah
Valley through the Piedmont.

Arctic high pressure centered over the Great Plains will approach
from the west Saturday before settling near the Tennessee Valley
by Sunday. A gradual warming trend ensues during the weekend into
the first half of next week. Afternoon RH values will drop into
the 25 to 40 percent range, but winds do not look hazardous during
this time.

A weak frontal system may impact portions of the area early next
week. Chance for wetting rain is pretty low at this point, with
the best chance up along the Maryland and Pennsylvania border. For
Central VA, much less chance for rain with this system. Winds are
expected to be light out of the SW, becoming more W/NW in the
evening. We don`t usually forecast this far out for mixing height,
transport winds and smoke dispersal, so feel free to request another
forecast with the most up to date information in a few days.
