AREA FORECAST DISCUSSION
National Weather Service Charleston WV
238 PM EDT Fri Jun 19 2020

.SYNOPSIS...
Upper low travels east away from the area through tomorrow.
Shower/storm chances diminish by end of Saturday. Upper ridge
builds for the weekend with heat and humidity returning.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 215 PM Friday...

Our old friend the upper low is finally going to depart the area.
With upper level flow picking up at slightly faster than what
the models have displayed will be all we need to send this low
out to the east by late evening taking shower and thunderstorm
chances with it. Clouds will clear out fairly well although
this will cause the area to be susceptible to fog for the early
morning. It shouldn't be too bad where it would make driving
difficult, however it may be bad enough for flying by closing
down an airport or two for several hours. This fog should mainly
be dense river valley fog which may spill over into other
locations. Other than that, relatively quiet weather as high
pressure builds in both aloft and at the surface for Saturday.
Expect right around average temperatures and there may even be a
chance for some afternoon pop-up showers or thunderstorms
although I don't think we will have to worry too much about
them. I believe if anything those pop-ups will be confined along
the eastern mountains in the extreme eastern portions of our
CWA. A somewhat light flow at the surface overnight will pick up
slightly out of the west late Saturday morning.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
As of 237 PM Thursday...

Models indicate an upper low should be centered over MD/DE at the
beginning of this period.  The upper low will finally opens up into
a trough and push off the eastern seaboard by late Sunday. An upper
level ridge is then expected to build over the area on Sunday with a
weak shortwave traversing the area by the end of the period.

With the upper low moving away, expect any showers and thunderstorms
will be diurnal in nature with chances decreasing Saturday night and
returning on Sunday.  However, the weak shortwave should result in
shower and thunderstorm chances continuing Sunday night into Monday.

Highs each day will be quite warm with readings generally in the
upper 80s across the lowlands and 70s across the higher elevations.
The combination of these temperatures and low level moisture will
make it feel a few degrees warmer.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 237 PM Thursday...

A broad upper level trough is expected to build over the area and
then basically remain in place through much of the period.  Several
shortwaves moving through the trough will impact the weather across
the region.  In addition, a cold front will push southeast Tuesday
night into Wednesday.

Expect daily chances for showers and storms with the greatest areal
coverage Tuesday night into Wednesday as the front pushes east.

Temperatures should be above normal on Tuesday. There should then be
a slight cool down behind the front for Wednesday and Thursday.
However, temperatures should rebound on Friday with readings
returning to normal values.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
As of 140 PM Friday...

Currently, showers are spreading across the eastern mountains
with some starting off in the lowlands. This will be the main
story for the next several hours until that upper low causing
this slides further east. The good news is upper level flow has
picked up a little faster than the models anticipated so the
low should exit sooner than later ending showers and chances for
thunderstorms in the early evening. At that point, clouds will
clear out fairly well leaving the area susceptible to fog later
on. With weak flow and saturate soils under mostly clear skies
fog will have potential to develop for early morning. Have
coded up some IFR fog in low stratus starting at around 5am
going until sunrise at virtually all sites except for BKW. They
may be able to fight it off, however they do go IFR for a few
hours before sunrise. Weak flow overnight will stir up out of
the west by late morning around 5KT+. For Saturday, expect high
pressure to build in and suppress a lot of shower and
thunderstorm chances for the day.

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

FORECAST CONFIDENCE: Medium to high.

ALTERNATE SCENARIOS: The duration of fog and stratus may vary in
teh morning and also could even become a lot worse at a site or
two (BKW in particular).
