What forecasters said that day

The local office's own words before this wind advisory went out, 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 this wind advisory went out at Apr 16, 3:29 AM EDT, 7 minutes earlier.

Area forecast discussion, Apr 16, 3:29 AM EDT, 7 minutes before
Area Forecast Discussion
National Weather Service Blacksburg VA
329 AM EDT Mon Apr 16 2018

.SYNOPSIS...
A strong cold front will continue to progress east of the region
this morning and offshore by afternoon. Much colder air on
strong northwest winds including mountain snow or rain showers
follows the front today into Tuesday. Weak high pressure builds
in on Wednesday with warmer and drier weather expected.
&&

.NEAR TERM /THROUGH TONIGHT/...
As of 300 AM EDT Monday...

Surface cold front will continue to push east of the region early
this morning followed by the actual 850 mb boundary that should
cross the Blue Ridge around 12z if not sooner. This looks to bring
about a prolonged period of cold advection into tonight as the large
upper low also pivots across including embedded shortwave energy.
Resulting lift with these impulses along with upslope flow should
keep periods of upslope rain/snow showers going with more
significant bands of snow showers possible northwest this evening
when the boundary layer cools more. However thinking any
accumulation during the daylight hours will be mainly confined to
the higher ridges with perhaps 1-3 inches overnight but not enough
for an advisory at this point. Otherwise the combination of cold
advection and subsidence within a 30-40 kt 850 mb jet likely enough
to warrant a wind advisory along the southern Blue Ridge today. This
may be limited by cloud cover but given wet ground and potential
surge in speeds this morning will hoist a headline for ROA to TNB
through 00z. Otherwise blustery and much colder mountains where
expect more clouds, while the east bumps well into the 50s per
downslope flow and more sunshine.

Strong pressure gradient remains in place tonight with deep
northwest flow aiding continued upslope along with gusty northwest
winds espcly mountains. Thus will maintain going high pops northwest
and clouds out to the Blue Ridge with mainly clear skies east. This
of concern with possible frost/freeze conditions out east although
given large temp/dewpoint spread not expecting much frost with lows
enough above freezing to preclude a freeze espcly given some light
mixing. Also winds may again ramp up late along the ridges behind
another passing wave as the 850 mb jet again cranks up to 40 kts
overnight. Lows mostly 30s east to 25-32 west.
&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
As of 315 AM EDT Monday...

Heights to rebound Tuesday into Wednesday as the upper low exits and
shortwave ridging develops between the two. This along with
increasing warm advection should make for warmer temps starting
Tuesday with highs ranging from the upper 40s northwest to mid 50s
Blue Ridge to mid 60s southeast. Will also see some increase in
mid/high clouds within the deepening warm advection Tuesday
night/Wednesday which will hold lows up a bit more Tuesday night
with only the far northwest going below freezing. Should be a
warm/breezy day Wednesday under rebounding temps aloft and enough
mixing to support highs mostly 70s under some sunshine.
&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 510 PM EDT Sunday...

With active weather in the near-term period, didn't spend as much
time with this forecast period with the forecast basis being from
the overnight 00z and 06z model suite, along with early 12z
guidance.

Warming trend to temperatures continues early in the period (thru
Thursday) before a cold front associated with a low pressure
area/clipper system passes to our north. Chances for showers appear
limited in this period. Brief cool down Friday into first part of
Saturday with below-normal temps indicated. Temperatures than begin
to warm along with moisture values as we await a progged strong
southern stream disturbance moving out of the mid-Mississippi Valley
to impact the region Sunday into Monday. This may bring another shot
of decent rainfall to the region.

&&

.AVIATION /08Z MONDAY THROUGH FRIDAY/...
As of 100 AM EDT Monday...

Showers/rain should continue to push slowly east overnight
before exiting the region over the next few hours. Still
looking at poor flying conditions with IFR cigs and at times IFR
vsbys.

Winds will shift from the south to west as the front moves
through overnight, reaching KROA 07z, and LYH/DAN 09-10z. Winds
will pick up behind the front especially after 12z, but should
expect sub-VFR cigs at least in the mountains through most of
the period.

Extended Aviation Discussion...

Gusty northwest winds will continue Monday night through Tuesday
along with mountain sub-VFR in low cigs espcly KBLF/KLWB.

Finally looking at a return to overall VFR on Wednesday with a
gusty southwest wind likely ahead of yet another approaching
cold front.

Next front arrives Wed night-Thu with chance of showers, with
gusty winds and sub-VFR cigs again Thursday in the mountains.

&&

.HYDROLOGY...
As of 100 AM EDT Monday...

Main concern overnight into Monday will be with runoff of heavy
rainfall from earlier causing rapid rises along creeks and
streams. This in conjunction with 1-4+ inches of rain that fell
during Sunday with the heaviest over the mountains where larger
mainstem rivers will likely rise into action stage or higher.
