A deepening area of low pressure departed off the New England coast, while high pressure moved eastward from the Plains. This pressure gradient caused gusty northwest winds that began during the day on March 10 and persisted into the early morning hours of March 11.

The episode as NWS RNK wrote it up.
A deepening area of low pressure departed off the New England coast, while high pressure moved eastward from the Plains. This pressure gradient caused gusty northwest winds that began during the day on March 10 and persisted into the early morning hours of March 11. The wet ground from rainfall on March 9 made trees and power lines more vulnerable to being blown down from these high wind gusts, which resulted in notable power outages.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Mar 10, 2:35 AM EST, 2 hours 25 minutes earlier.
Area Forecast Discussion
National Weather Service Blacksburg VA
335 AM EDT Sun Mar 10 2024

Monday with the passage of a cold front. A few upslope snow
showers are possible for the mountains. Dry conditions are
expected Monday through Thursday under high pressure with
warmer weather returning.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 315 AM EDT Sunday...
Key Messages:
1. Very gusty winds today and tonight, with Wind Advisories and
High Wind Warnings in effect.
2. Light rain and snow showers for the mountains ending later
today. Low snow accumulations for Western Greenbrier County.
3. Very cold tonight...bring your pets in!
Strong winds and chilly temperatures will produce wind chills
in the teens and 20s today, making it a good day to stay in,
read a book, and change your clocks.
A cold front has crossed most of the forecast area this morning.
Upslope snow and rain showers were ongoing over the mountains
and foothills in strong NW flow. A 55 knot LLJ over the area
will keep the pressure gradient piling up on the west side of
the Blue Ridge. This, in addition to moderate CAA, will help to
keep NW winds very gusty through today and tonight. Winds were
gusting to 25 to 35 mph at many sites, with a 47 mph gust
already recorded at Boone. While a Wind Advisory remains in
effect from the Blue Ridge westward, Watauga, Ashe, Alleghany,
and Grayson Counties have been upgraded to a High Wind Warning,
with gusts to 50-60 mph possible at our highest elevations.
Occasional rain and snow showers will continue for southeastern
WV and parts of VA today. Flurries or sprinkles may be carried
well downstream and even reach the I-81 corridor. Little to no
snow accumulation is expected outside of Western Greenbrier
County, WV, where 1 to 3 inches will be possible.
Tonight will be very chilly with winds decreasing some but still
gusting to 15 to 25 mph. Continued CAA and clearing skies will
allow for lows in the 20s and 30s, with wind chills in the
single digits and teens for the mountains. Temperatures in the
Piedmont will not be quite as chilly with the mountains holding
back the brunt of the colder air.
Confidence in the near term forecast is high.
&&
.SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/...
As of 300 AM EDT Sunday...
Key Messages:
1) Confidence is high for dry weather throughout this period.
2) Gusty winds on Monday should subside by Monday evening, and
warmer air will arrive for Tuesday and Wednesday.
The gusty northwest winds will continue into Monday but should
gradually fade by the afternoon as high pressure builds across
the Southeast. The winds will finally relax on Monday night, and
a much quieter weather pattern will ensue. Dry conditions
should persist through Tuesday and Wednesday. Because the center
of high pressure will stay to the south and exit offshore
during late Tuesday into Wednesday, the flow across the Mid
Atlantic will turn towards the southwest and provide warm air
advection. Temperatures should jump into the 60s on Tuesday in
the Piedmont, and a few lower 70s are possible by Wednesday.
&&
.LONG TERM /THURSDAY THROUGH SATURDAY/...
As of 300 AM EDT Sunday...
Key Messages:
1) Confidence is increasing for the next chance of rain arriving
by Friday and lingering into Saturday.
2) Temperatures should stay well above normal with Thursday
being the warmest day.
Even warmer air will arrive on Thursday as a broad upper level
ridge builds across the eastern United States. Temperatures
could reach the mid 70s in the Piedmont by Thursday afternoon,
which is between fifteen and twenty degrees above normal for
this time of year. Clouds will increase during Thursday night
into Friday as a cold front moves eastward. Rain chances have
been increased for Friday. The cold front will weaken and stall
across North Carolina during Friday night. This stalled frontal
boundary may keep more clouds and rain chances into Saturday
across the Appalachian Mountains, but the models vary
considerably by this point to give any further details.

.AVIATION /07Z SUNDAY THROUGH THURSDAY/...
As of 245 AM EDT Sunday...
A cold front has crossed most of the forecast area this morning.
Upslope snow and rain showers were ongoing over the mountains in
strong NW flow. Winds were gusting to 15 to 25 knots already in
strong CAA. 55 knot LLJ was over the area as well and will help
to keep winds gusty through today, tonight, and Monday. Gusts
as high as 40 kts possible at ROA/BLF. Pressure gradient finally
relaxes tomorrow afternoon allowing for winds to decrease but
they remain breezy even after that.
Seeing a mix of VFR and MVFR behind the cold front, with BLF
still IFR. We will see improvement everywhere as the day goes on,
with areas east of the mountains scattering out, and MVFR to
VFR for the mountains. -SHRA/-SHSN may briefly reduce vsby below
2SM. These showers diminish through the day.
.EXTENDED AVIATION OUTLOOK...
High pressure with dry VFR conditions are expected Monday
through Thursday.
