.AVIATION /02Z THURSDAY THROUGH MONDAY/...
A strong cold front approaching the I-95 corridor will move east
overnight and across the Chesapeake Bay. Winds have or will
shift to a west-northwest to northwest direction and gust over
40 knots. Heavy rain and embedded thunder will lower ceilings to
LIFR or IFR but visibility should be MVFR to VFR. Showers may
linger for a few hours behind the front before conditions dry
out during the second half of the night. Low level wind shear
will also be possible immediately in the wake of the front this
evening.

Prevailing VFR conditions are expected tomorrow. A few mixed
rain/snow/graupel showers may be possible tomorrow afternoon,
but the vast majority of the time should remain dry. Winds will
remain out of the west. Mixed rain and snow may potentially
impact some of the terminals Friday morning. Any precipitation
would change over to plain rain by Friday afternoon.
Gusty WNW winds around 20 to 30 kts will be the main threat to the
terminals on Saturday at the terminals. Otherwise, VFR conditions
are expected as we transition into a period of high pressure that
will then continue into Sunday. Winds turn more westerly on Sunday
and will be around 10 to 20 kts.
