Area forecast discussion, May 22, 2:12 PM EDT, 29 minutes before

Area Forecast Discussion
National Weather Service Charleston WV
212 PM EDT SUN MAY 22 2016

.SYNOPSIS...
Upper level low lingers above mid Atlantic states through Monday
night. High pressure over Ohio/Tennessee Valleys Monday into
Tuesday. Warmer for mid and late week with afternoon showers and
thunderstorms.

&&

.NEAR TERM /THROUGH MONDAY/...
Upper low moving overhead today sliding down the eastern side of
the Appalachians providing instability for some afternoon and
early evening showers and tstorms. Precipitable water around 0.75
inch...so showers should not be very heavy.

Showers on the retreat overnight but some chance remains overnight
across the mountain counties closer to the upper level low.

May see some patchy fog overnight with saturated lower atmosphere.
Monday afternoon may see another round of showers, but think these
will be even more widely scattered than this afternoons round as
upper level forcing moves off to the east and CAPE minimizes.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
Not too much going on in the short term with high pressure
building into the region. Temperatures will start to rise as
ridging and southwesterly return flow starts to bring warm
tropical air mass overhead. Although...moisture will be on the
increase on...with dew points starting to climb into the low 60s
by the afternoon...it appears that showers and thunderstorms may
hold off. For now I went with a model consensus and bring slight
chance to low chance PoP into the Ohio Valley by late Wednesday
afternoon. However...the greater influx of moisture will take
place during the long term period starting on Thursday.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
Get ready for summer! Bermuda High to our Southeast will bring
warm tropical air into the region with southwesterly return flow
off the Gulf pumping northward across the Eastern U.S.
Temperatures will soar into the upper 80s by the end of the week
with Dew Points possibly getting close 70F. Diurnal showers and
thunderstorms will be possible each day...as we maximize daytime
heating in the afternoon hours. Flow aloft will be weak with high
Cape values...so pulse air mass storms could bring localized heavy
rainfall. With already moist ground in place...any storms that can
develop over more flash flood prone areas will have to be
monitored closely.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
Vfr with a little potential for mvfr showers/thunderstorms this
afternoon. High low level moisture overnight may lead to another
round of fog early monday. Another round of showers monday
afternoon, but more scattered in extent.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY...

FORECAST CONFIDENCE: Medium.

ALTERNATE SCENARIOS: Conditions may go to mvfr more often than
