.DISCUSSION...
High pressure will build from the Great Lakes to the Northeast and
Mid-Atlantic today, then move offshore tonight as a warm front
approaches from the Ohio River Valley. The warm front will lift
across the area Sunday as low pressure moves from the Upper
Midwest to the Great Lakes and southeastern Canada. A trailing
cold front will cross the region Monday, then a secondary dry cold
front will cross the area Tuesday. High pressure will follow for
the middle of the week before another frontal system crosses
Thursday into Friday.
Northerly wind gusts of 15 to 20 mph are likely over the Blue
Ridge and Catoctin mountains, as well as near and east of
US-15 through early this afternoon. At the same time, abundant dry
air advecting into the region will drop relative humidity to 25 to
35 percent, locally 10 to 20 percent over 2000 feet elevation by
early to mid afternoon. A window of overlap between breezy and dry
conditions may exist for several hours around midday, resulting in
locally elevated fire weather conditions and the threat for rapid
fire spread.
Winds will turn to the southeast tonight, becoming light to calm
in the lower elevations while gusting 15 to 25 mph over the higher
elevations. RH recovery will be modest overnight, generally 60 to
80 percent by daybreak Sunday. Southerly wind gusts of 15 to 25
mph are anticipated Sunday, but RH will be rising during this time.
A widespread wetting rain ranging from a quarter to half inch is
likely Sunday into Monday as a cold front crosses the region.
