AREA FORECAST DISCUSSION
National Weather Service Charleston WV
1055 PM EDT Fri Mar 27 2020

.SYNOPSIS...
A warm front drifts north tonight with showers and thunderstorms
riding along the front. A cold front crosses Sunday morning.
Another system Tuesday into Wednesday.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 1055 PM Friday...

No changes needed at this time.

As of 730 PM Friday...

Latest surface analysis depicts warm front has largely remained
in place over the past several hours. Showers have shifted into
far northeastern counties with not much going on upstream in
the OH Valley currently. Latest hi res models keep the bulk of
anticipated renewed activity overnight skirting our northern
forecast area as the warm front slowly moves north. In the warm
sector it will remain very mild overnight with temperatures
likely to remain north of 60 degrees.

As of 145 PM Friday...

As of writing, an effective warm front was located from just
south of KHTS extending eastward to between KCRW/K6L4 and just
about on top of KBKW. Some isentropic upglide over this boundary
is resulting in persistent rain across the far northern CWA
where temps are in the 50s...compared to temps in the 70s south
of the front.

All-in-all, primary forecast challenge continues to be timing
and placement of convection. The aforementioned boundary is
expected to gradually shift northward this afternoon and
tonight...and should stall across the northern third of the CWA.
Rounds of convection are prog to develop later today and
tonight across the Mid MS Valley and ride east along the
boundary...primarily affecting our CWA during the overnight
hours. How far north this boundary makes it will ultimately
determine how much of the CWA will experience convection
tonight.

Overall, I have included 20 POPs for most of the southern half
of the CWA this afternoon and evening just in case convective
temps are reached. Farther north, a pretty sharp gradient of
POPs exists from south to north where overnight convection is
expected. For now, the heaviest rain is expected to remain just
north of our CWA, but any training overnight could lead to
isolated high water issues. An isolated strong storm may also
occur tonight closer to the boundary where elevated convection
could result in some hail development.

Drier conditions are expected during the day Saturday as
southwest flow strengthens in the lower and mid levels and mixes
out the higher moisture values.

Temps tonight will be strongly dependent on how far north the
boundary moves, with some areas experiencing warming temps
overnight. Very warm H85 temps of 14 to 16 C on Saturday, along
with some notable diurnal mixing, should result in near record
to record highs in the afternoon.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
As of 235 PM Friday...

The short term opens up with the center of a strong low
pressure system migrating into the Great Lakes region Saturday
night, sending a cold front through the Ohio Valley. Storms
ahead of the front will have the capability of reaching severe
strength, leading to the threat of damaging wind gusts and hail
as well as a lesser threat for tornadoes. Antecedent conditions
from previous rainfall on Friday and Saturday may impose
localized flooding issues in flood prone and low lying areas,
especially in heavier rain bands.

POPs taper off from west to east Sunday as the moisture and
energy source associated with the frontal boundary exits into
New England. However, strong winds aloft in response to
strengthening jet stream dynamics will mix down during the day
and inflict strong wind gusts on the upwards of 30 to 35 mph
areawide. These winds will fester until Sunday night once
daytime mixing has concluded and the jet charges eastward.

Monday looks to be the driest day of the short term period with
high pressure parked across the Tennessee Valley. Temperatures
will be on the cooler side in the wake of the front, returning
to more seasonable values for this time of year.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 245 PM Friday...

Active weather commences once again early on in the period as a
result of low pressure ejecting out of the Central Plains. The
area of heaviest rain will be more focused south of the forecast
area, but I do carry likely POPs as far north as the Charleston
metro for Tuesday night into Wednesday. Lingering showers
Wednesday will trail off over the mountains as high pressure
takes dominance for the end of the work week. Elected to
undercut central guidance POPs for the end of the period as it
was holding on to rain when drier air will begin to overpower
the region.

Temperatures remain around normal for the daytime hours through
the second half of the week. A few more disturbances look to be
on the horizon for the end of the period and into the start of
next weekend.

&&

.AVIATION /03Z SATURDAY THROUGH WEDNESDAY/...
As of 734 PM Friday...

Warm front will slowly lift north overnight with a wind shift to
the south and southwest. Showers and perhaps some elevated
convection may skirt northern terminals late which could result
in restrictions, otherwise VFR conditions are anticipated.

Warm front will lift well north of the area Saturday with VFR
conditions in broad southwest flow, gusting to 20 kts by midday.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z SUNDAY...

FORECAST CONFIDENCE: High.

ALTERNATE SCENARIOS: Convection overnight may stay just north
of KPKB/KCKB/KEKN.
