VFR conditions with SCT-BKN CU and AC deck this aftrn. Shwrs and
tstrms dvlpng along and east of I95 where lcl CIGS will drop to
MVFR with psbl IFR VSBYS in hvy rain. Gusty wind in excess of 30
kts psbl with any storm. Sea-breeze influence has shifted the winds
to the ESE along the coast this aftrn. Otw, S wind blo 10 kts.
Given current radar trends, have started off the forecast with
VCTS at RIC. Tried to time the thunder at sern TAF sites based
off the latest high res data.

Convection continues into the eve ivof the Ches Bay then weakens
and dissipates by midnite. Some ptchy fog psbl once again at SBY
tonight and where it ends up raining today.

Outlook...
Additional convection expected both Wed and Thurs ahead of an

&&

.MARINE...
As of 230 PM EDT Monday...

Southeast flow this afternoon has increased to 10 to 15 kt
across the lower Bay and coastal waters south of Cape Charles.
Winds were a little lighter over the middle and upper Bay.
Expect winds to persist this afternoon and evening near 15 kt at
times. Some strong gusty winds are possible this evening from
storm outflow as storms approach the rivers and Bay from the
west. Waves in the Bay/Sound/Rivers ~1-2 ft, seas generally 2 ft
(3 ft offshore) through this evening and tonight.

Similar conditions for Tuesday with surface ridging along the
coast from the Bermuda high as a low moves northeast across the
Ohio River Valley. This will result in continued south to
southwest winds ~15kt by Tuesday aftn. Waves in the bay will
persist closer to 2 ft with seas up to 3 ft on the ocean Tue-
Wed. A weak front tries to push into the area Wednesday, but
looks to stall and wash out resulting in showers and storms,
but no significant winds. Winds could briefly turn around to
the W-NW (< 15 kt) over northern waters, but quickly back to the
W-SW 10-15 kt later Thu and through next weekend. Expect
conditions will stay below SCA thresholds.

Looking ahead, do not anticipate any marine issues or headlines
as the bermuda high remains in control of the southeast US. The
Pressure gradient may tighten some for Saturday and Sunday
resulting in a southwest wind around 15 kt.
