.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
VFR conditions had returned to most of the TAF sites as of 18Z
as a warm front lifts passed and a cold front quickly follows.
This is shifting winds around to the west, with gusts of 15-20
kts. Iso TS possible mainly SE of DCA. SHRA activity should
diminish into this evening, though some iso light activity could
linger until a little after sunset. Wind gusts will subside this
evening, as well.
VFR conditions and gusty NW winds are expected Friday. Gusts
could exceed 30 kts at times. A couple of pop up showers are
possible. Winds will become lighter Friday night, then gusts
resume during the day Saturday but at slightly lower speeds as
high pressure passes to the north. Winds slacken again after
dark Saturday night while remaining NW.
Sub-VFR conditions will be possible at times if the region
experiences showers and thunderstorms Sun-Mon. The best chance
for aviation restrictions in the long term will be Tue-Wed.
