.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/...
As high pressure pushes offshore today, southerly winds will
gust up to 15 to 20 knots. Some isolated to scattered showers
may impact the terminals by Wednesday evening/night.
A cold front will approach the region on Thursday. A few strong
to severe storms are possible that afternoon/evening, with
gusty winds being the primary threat. There are even some indications
that a couple of rounds of storms are possible, one in the
early afternoon and one later in the evening.
As the front stalls nearby Thursday night, some MVFR to IFR
ceilings or visibilities may develop. Showers and storms could
even linger into Friday, but unsure if this would impact any of
the terminals at this time, as the front should stall east of
I-95 and focus that threat east of most of the terminals. Can't
completely rule out some restrictions though.
Prevailing VFR conditions are expected Saturday. Winds shift
out of the north to northeast on Saturday and are expected to
remain light.
