AREA FORECAST DISCUSSION
National Weather Service Charleston WV
233 PM EDT Fri Jun 14 2024

.SYNOPSIS...
A chance for showers and storms this afternoon and evening with
a cold front. An extended stretch of hot and dry weather will
begin Sunday and last much of next week.

&&

.NEAR TERM /THROUGH SATURDAY/...
-- Changed Discussion --
As of 230 PM Friday...

After coordinating with SPC, a severe thunderstorm watch has
been issued for northern counties in southeast OH, and northern
WV until 9 PM this evening. Plenty of sunshine and available
moisture will continue to destabilize the atmosphere this
afternoon providing descent bouyancy. Strong to severe
thunderstorm are expected.

As of 130 PM Friday...

Cold front exits east of the Appalachians late this evening, with
lingering light showers ending by midnight. Surface high pressure
builds from the north tonight into Sunday providing light to calm
flow and mostly clear skies. This set up will allow for river valley
fog to develop along river valleys and over areas that received
rainfall today and tonight. Any fog or low stratus that manage to
develop will quickly dissipate by 9 AM Saturday.

Lows tonight will generally be in the lower 60s across NE KY, SW VA
and southern WV, ranging into the 50s northern sections and
northeast mountains. Plenty of sunshine and light winds will prevail
on Saturday providing a warm afternoon, with temperatures ranging
from the mid 80s lowlands, into the lower 70s higher elevations.

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 1207 PM Friday...

Upper-level high pressure will be centered over the Deep South
Sunday, slowly moving northeastward throughout the day. Temperatures
will start to heat up across the lowlands with afternoon highs
expected to be in the lower 90s by Sunday afternoon. Winds will
become southerly, leading to the return of more humidity. Expect
heat indices to reach the lower and middle 90s across the
lowlands Sunday afternoon. This will just be the start of an
extended stretch of hot and dry weather on the way. The cooler
spots will be the higher elevations of the West Virginia
mountains, where temperatures will remain in the 70s and lower
80s during the hottest parts of the day.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
As of 1207 PM Friday...

Confidence in the potential of a heat wave over the region next week
is increasing. Models seem to be coming into better agreement
regarding the placement of the upper-level ridge axis, which seems
to be right over or slightly east of the Appalachian mountains for
much of next week. This would provide support for an extended
stretch of very hot and dry weather across most of the region, with
the exception of the higher elevations, where temperatures will be
cooler and isolated thunderstorms may develop. Rain chances next
week look minimal at this time, but if the upper-level ridge ends up
being farther to the east than what models are currently predicting,
then our region could end up cloudier and cooler with more
convection. That will be one thing to watch over the coming days
with subsequent model runs. However, if our current forecast of
largely dry weather pans out, many places will likely see worsening
drought conditions throughout the week.

From Monday through next Thursday, highs are projected to reach the
upper 90s across the lowlands with heat index values approaching 100
degrees each afternoon. It will be very important to put heat safety
into practice next week. This includes drinking plenty of fluids,
taking frequent breaks in the air conditioning or the shade whenever
possible, checking on the elderly and sensitive groups, and using
plenty of sunscreen. Stay tuned for updates as the potential heat
wave approaches.

.AVIATION /17Z FRIDAY THROUGH TUESDAY/...
-- Changed Discussion --
As of 130 PM Friday...

A weak cold front crosses the area this afternoon and evening
spreading mainly clouds and showers. Satellite imagery shows
clear skies across most parts of the area early this afternoon.
Clouds will increase in coverage while a few showers and storms
develop under the afternoon heat. The heat and humidity will
provide bouyancy and weak convection for the most part. Few
storms may become strong to severe across the northern sections,
possible affecting PKB and CKB where dynamics are stronger.

Convective activity is expected to subside before or during
sunset. Few light showers may linger across the mountains into
the evening, but all will dissipate early tonight leading to
mostly clear skies for many overnight. If the clearing
materializes, dense fog will develop over those wet areas
overnight into Saturday morning, affecting mainly the northern
terminals such as EKN and PKB and other river valleys.

Outside of any t-storms, winds should remain on the lighter
side - generally SW-W`ly ahead of the front, and N`ly once it
pushes through.

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

FORECAST CONFIDENCE: Medium on timing and coverage of storms
this afternoon and evening. As well as for coverage of dense fog
overnight into Saturday morning.

ALTERNATE SCENARIOS: Thunderstorms could wind up a bit more
widespread than expected. Fog extent and timing tonight may
differ from the forecast.
