.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/...
A cold front is moving through the area this morning with gusty
northwest winds in its wake. Ahead of this front (the metro
areas as of 330 AM), there may be some marginal low level wind
shear with light southerly or calm winds beneath an inversion,
with 30-40 kt NW winds at 2000 ft. Lingering stratocumulus
clouds are beginning to depart. Expect the stronger
northwesterly winds to mix down across the rest of the area near
to a couple hours after sunrise. 15-25 kt gusts are possible
through the morning before winds start to decline this
afternoon. Winds will be light and variable most of tonight as
high pressure moves across the area with increasing mid and high
level clouds.
A wave of low pressure may bring some light rain showers late
tonight through Thursday morning, with the highest chance at
CHO. The main impact will come from ceilings though, which will
lower to MVFR at times Thursday morning. Conditions may improve
Thursday afternoon. A cold front will cross by Thursday evening,
and northerly winds may be gusty for a time.
A low pressure system will affect the area Friday into Friday
night. The most likely time frame for precipitation is Friday
afternoon and evening. BWI, MTN, and MRB likely see sleet and
freezing rain and possibly a little snow to start. Wintry
precipitation is a bit more uncertain for IAD/DCA. CHO is likely
mostly rain. IFR conditions likely develop which last through
Friday night.
CIG restrictions could continue into portions of Saturday with
moisture overrunning a boundary over the Carolinas, especially
across northern and eastern terminals. By Sunday, rain overspreads
the region ahead of a strong cold front. Thus, expect additional
periods of sub-VFR conditions across the terminals.
