Area Forecast Discussion
National Weather Service Blacksburg VA
215 PM EST Fri Mar 3 2023
.SYNOPSIS...
A cold front will cross the Appalachian Mountains tonight to
bring gusty winds and rain. The gusty winds will persist into
Saturday but fade by Saturday night as high pressure arrives.
Milder and drier conditions are expected for Sunday and Monday,
but the next chance of rain may come by Monday night.
&&
.NEAR TERM /THROUGH SATURDAY/...
As of 215 PM EST Friday...
Confidence is high for gusty winds tonight into Saturday.
The atmosphere remains stable with high pressure wedged against
the eastern slopes of the Appalachian Mountains. A cool
easterly flow and widespread cloud cover will limit any warming
for the remainder of this afternoon. Low clouds with some
occasional rain or drizzle should persist during this time. High
temperatures were kept well below most of the model guidance as
they are not handling the wedge at all. Only the cooler MET
guidance appears to have any idea about this situation.
Temperatures may start to creep up along the North Carolina and
Virginia border late this evening as the cool wedge starts to
weaken in response to an approaching cold front. A line of
showers just ahead of the front should approach the western
mountains by 6 PM EST and exit east of Route 29 around 11 PM
EST. The wind shear is extremely impressive, but the question
remains about getting any kind of CAPE at all to allow mixing of
the stronger winds aloft down toward the surface and to promote
enough convective growth to spark isolated rumbles of thunder.
If the storms get strong enough west of the Blue Ridge, then
there remains a risk of damaging winds and an isolated tornado.
Winds will increase from the southeast this evening as the cold
front approaches. A strong low-level jet reaching 60 knots will
pass overhead tonight. After the frontal passage, winds should
swing around to the west. Model soundings show strong gusts
overnight and into Saturday morning, so no changes have been
made to the wind headlines. A few upslope showers or snow
flurries may occur across western Greenbrier County on Saturday
morning, but all locations should see clearing skies as drier
air arrives in the afternoon. Dewpoints were decreased across
the Piedmont due to the expected downsloping and mixing. There
should be a notable gradient in high temperatures with 40s in
southeast West Virginia and 60s east of the Blue Ridge.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 130 PM EST Friday...
Dry through most of the period, with mountain showers
associated with a cold front on Monday night...
Looking to Saturday night, high pressure will gradually drift
eastward, settling across the central Appalachians by dawn
Sunday. Wind speeds will have diminished significantly by this
point, becoming near-calm for most locations. Combine the light
winds with clear skies, and we can expect strong radiational
cooling that will allow temperatures to fall to near or below
freezing areawide, with deeper valleys likely to dip into the
20s. This will be the coldest night of this 3-day period.
High pressure will then continue east, allowing winds to
eventually switch from a southerly direction to make for a
gradual warmup into Monday night. Sunshine will be abundant on
Sunday as high pressure passes overhead, with increasing clouds
on Monday as another cold front approaches from the west. With
polar air locked well to the north of our area and modest upper
level ridging developing early next week, temperatures will
remain 6-10 degrees above normal for Sunday and anywhere from 8
to 14 degrees above normal for Monday.
A cold front will arrive Monday night, bringing rain showers
mainly to the mountains, which are expected to diminish due to
downsloping as they pass east toward the Piedmont. As such, the
higher terrain from southeast West Virginia through the North
Carolina High Country can expect the highest rainfall amounts,
though no more than a quarter inch seems likely at this point.
Forecast confidence is high.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 145 PM EST Friday...
Temperatures return to near-normal, mainly dry through the
period...
With the passage of a cold front before dawn on Tuesday,
Canadian high pressure will build across the lower Mid-Atlantic
through the day, resulting in gusty northwest winds. May see
rain showers linger into early afternoon across southeast West
Virginia, however these will diminish as drier air builds in.
Clouds will linger longer into the day across the mountains, but
will break up further east to allow for afternoon sunshine
across the Piedmont in the downslope windflow, which will make
for a wide gradient in afternoon high temperatures.
Cool high pressure will then maintain control of the weather
pattern for Wednesday and Thursday, with temperatures returning
closer to normal for what will be the second week of March. This
will include the likelihood of freezing overnight temperatures
across the region, which may impact vegetation which is
sensitive to the cold that may have already begun sprouting.
Weather forecast models have all backed off on precipitation
chances for Wednesday and Thursday with a low pressure system
developing across the Mid-Mississippi River Valley, with the
brunt of the energy remaining to our west. Have lowered rain
chances for the middle of next week with this latest forecast
package, but opted not to remove them outright until consistency
develops within the consecutive updates of the model data.
Forecast confidence is average, but remains low regarding the
midweek system.

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
As of 120 PM EST Friday...
Conditions have deteriorated to LIFR at BCB, BLF, and DAN at
this hour. ROA has reached IFR, while LWB and LYH have worsened
to MVFR. Confidence is high that all of these terminals will
fall to IFR/LIFR during the remainder of this afternoon due to
a cool easterly flow and substantial cloud cover. BLF will have
a low-level wind shear threat for the rest of today due to a
strong low-level jet approaching from the west.
The poor aviation conditions will not improve until after a
cold front arrives later tonight. A gusty line of showers could
reach BLF and LWB by 00Z/7 PM EST and exit east of LYH and DAN
toward 04Z/11 PM EST. There is a slight threat of thunder
embedded within this line, but confidence remains too low to
mention in the TAFs. However, winds will increase considerably
as they shift from the southeast ahead of the line toward the
west behind it. Low-level wind shear has been inserted into all
terminals to accompany the timeframe for the passage of this
line of showers and possible thunderstorms.
Winds will gust even higher after the frontal passage during
late tonight into Saturday morning. Surface gusts could reach
30-40 knots for all terminals. Some locations along the higher
elevations may see higher values such as in the northwest North
Carolina mountains where surface gusts of 40-50 knots may be
possible. Conditions will improve to VFR east of the Blue Ridge
during Saturday morning, but it may take until Saturday
afternoon for locations west of the Blue Ridge to exit MVFR/IFR
due to low clouds. Winds should gradually diminish toward
Saturday evening as high pressure approaches.
Extended Aviation Outlook...
High pressure should build across the Mid Atlantic on Saturday
night, so good flying weather is expected for Sunday and
Monday. Clouds should increase by late Monday as a cold front
approaches to provide showers and potential MVFR conditions for
Monday night into Tuesday west of the Blue Ridge. However, the
moisture may struggle to reach the Piedmont and not cause much
impact. Gusty winds and an improvement to VFR is anticipated for
Wednesday as high pressure returns.
