Mid-Atlantic states as the lingering effects of Issac dominate the
forecast. Lingering tropical moisture will keep the threat for
scattered afternoon showers/storms over West Virginia this afternoon
as highs reach the mid 80s. Any thunderstorms that creep up this
afternoon could produce locally heavy rainfall & minor high water
problems in spots. Our overnight will remain muggy & mostly cloudy
with a chance for leftover rain/thunder into early Wednesday. Lows
will stay in the upper 60s. Eventual clearing is forecast by Wednesday
afternoon as high pressure provides a brief break from the wet weather
into Wednesday night & for much of the day on Thursday.
A weak disturbance will cross our area Thursday night with little
moisture to work with. So we can expect just a few passing clouds and
perhaps some isolated drizzle in the eastern mountain counties
Thursday/Friday. Another upper level disturbance is timed to bring
rain & slightly cooler temperatures Friday night into the coming
weekend.
Pictured, we still have warm, moist air lifting steadily northward. We
can also make out the next weak cold front timed for Thursday night.
