Area Forecast Discussion
National Weather Service Blacksburg VA
207 PM EDT Sun Mar 31 2024

.SYNOPSIS...
A frontal boundary will remain in the area, helping to keep
scattered showers and thunderstorms chances through midweek.
Widespread rain looks most likely Tuesday into Wednesday. Rain
and snow showers will linger over the mountains Wednesday night
possibly through Friday. We remain well above normal for
temperatures through Tuesday, with cooler weather the latter
half of the week.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 2 PM EDT Sunday...

Key Messages:

1. Low confidence in thunderstorm development this afternoon.

2. Greater chance for isolated strong to severe thunderstorms
Monday afternoon into evening.

Convective activity tracking ESEWD near and along a frontal
boundary slowly sagging southward has been overall lackluster
and has even lost most lightning activity as it crosses the
Appalachians. That being said, there is an axis of some
increased instability and there still remains an isolated threat
for some strong to severe development with decent deep layer
shear and cool thermal profile aloft. The northern half of the
CWA has largely been under a rather thick stratocu deck and with
a bit more stratiform precip currently tracking across from the
decaying previous approaching convection, the upstream
environment isn't the greatest for redevelopment.

Should see a lull in precip for this evening into overnight,
then Monday looks to have a bit greater destabilization with
still decent deep bulk shear near 50-70 kts. HRRR neural network
probs are also greater so am weighing in on the isolated strong
to severe threat higher Monday. SPC has most of the CWA in a Day
2 Marginal Risk as well. Max temps Monday afternoon mainly nudging
up a few degrees higher than today so expect generally near 80
in the Piedmont and low to mid 70s in the mountains.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
... As of 130 PM EDT Sunday...

Key Messages:

1. Thunderstorms expected, with some possibly severe, late Tuesday
into Tuesday night.

2. High confidence for above normal temperatures, with minimum
temperatures Tuesday morning near or above record high values.

3. Gusty winds, upslope snow showers Wednesday into Wednesday night.

The deterministic medium range models are in good agreement that
upper level heights rise in advance of an anomalously deep upper level
and leading shortwave trof.

A cluster of showers and storms may be ongoing at the start of
Tuesday in the northern portions of our area as a strong low level
jet advects higher theta-e air over a nearly east-west oriented
stationary front expected to be positioned north of I-64. The track
of this complex of storms and amount of debris clouds will have a
significant influence on highs Tuesday. With most indicators,
including the ECMWF extreme forecast index for QPF, showing the axis
of heaviest rain falling north of our area, leaned toward the warmer
MET temperatures for highs on Tuesday, especially in the southern
portion of our region.

During the rest of the day on Tuesday, forecast soundings agree that
a fairly robust cap will be place, and lowered POPS from mid morning
to late afternoon. Winds should be brisk, especially across those
favored locations for strong southwest winds (Mercer/Tazewell
counties, where the GEFS shows 30-40% chance of gust reaching or
exceeding 40 MPH). After 21Z, better upper dynamics and the approach
of a cold front from the west should allow storms to enter the
western part of our forecast area. While the best combination of
instability and shear will be just to our west, there should easily
be enough forcing to allow storms to move into our area with a few
possibility severe, with damaging winds the main hazard.

As the front sweeps through early Wednesday morning, the best
instability and deepest moisture will be shunted east of our area by
12Z Wednesday, but expect scattered showers and some mountain snow
showers to linger Wednesday in advance of a deep upper level low.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
...As of 120 PM EDT Sunday...

Key Messages:

1. Confidence remains high for gusty winds and below normal
temperatures late this week.

2. Accumulating upslope snow showers possible Wednesday into
potentially Friday.

An anomalously deep upper level low should continue to influence our
weather through the long term period with an omega block pattern
expected to be in place. This will keep temperatures below normal
and bring a prolonged period of upslope snow showers, with the GEFS
showing greater than a 90% chance of 3" or more of snow along the
western slopes of West Virginia through at least Friday.

In the wake of the upper level trof axis sweeping through early
Thursday, impressive pressure rises and a deep mixing layer should
bring strong winds that forecast soundings suggest could exceed
advisory criteria, or stronger for the southern Blue Ridge. Will
continue to highlight this hazard in the HWO.

Leaned toward the cooler guidance for temperatures during this
period and confidence is high these values will be blow normal with
perhaps some moderation by Sunday.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
As of 155 PM EDT Sunday...

Some showers and possible TSRA look to impact most sites this
afternoon except KDAN. This could bring reduced cigs/VSBYs near
MVFR and VRB gusts. Otherwise some cigs near 4-7 kft, then
overnight lower cigs near LIFR/IFR for KLYH, KROA, and possibly
KDAN. Precip chances increase during the day Monday with a bit
greater chance for showers and thunderstorms. Winds generally
west to SW today 8-12 kts gusting 16-20 kts, then decreasing
overnight and possibly light and VRB. Monday winds look to be
west to SW again with similar daytime magnitudes. Monday night
could have similar lowered cigs as well with continued shower
and thunderstorm chances.

EXTENDED AVIATION OUTLOOK...

Continued sub-VFR with showers and thunderstorms Tuesday and
Wednesday. Southwest winds will be gusty ahead of the front
Tuesday with even stronger northwest winds behind the system
Wednesday to Thursday.
