PWWhat forecasters said that day
The local office's own words before this severe thunderstorm warning 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 severe thunderstorm warning went out at Apr 15, 3:51 PM EDT, 17 minutes earlier.
Area forecast discussion, Apr 15, 3:51 PM EDT, 17 minutes before
Area Forecast Discussion
National Weather Service Blacksburg VA
351 PM EDT Sun Apr 15 2018
.SYNOPSIS...
A strong cold front will continue to progres across the region
this evening, and offshore by early Monday. A line of showers
and thunderstorms will precede the boundary this afternoon into
tonight before drier air arrives overnight. Storms may be strong
to locally severe. Much colder air on strong northwest winds
including mountain snow or rain showers follows the front for
early next week.
&&
.NEAR TERM /THROUGH MONDAY/...
As of 349 PM EDT Sunday...
Issued Tornado Watch 53 which includes the Piedmont of VA/NC, Blue
Ridge foothills, New River and Roanoke Valleys until 03z/11pm. I've
removed Ashe and Watauga Counties from Tornado Watch 52, which
remains in effect until 7 PM. Flash Flood Watch were expanded with
the afternoon package northward, per collaboration with NWS
Sterling, into Bath, Rockbridge, Botetourt and Alleghany Counties in
VA.
Ongoing QLCS with several kinks embedded in the line extended from
Mercer County WV southward into eastern SC; we are also carefully
monitoring cluster of multicells moving north from the Triad into a
somewhat more unstable environment in the VA Piedmont/Southside. Air
mass remains highly sheared owing to strong low and mid-level wind
fields. No change to prior thinking that the main threats will be
damaging winds and perhaps short-lived/brief tornadoes, with hail
being a secondary concern associated with supercell structures.
Reported rain rates have been torrential at times and it will take
training to produce flash flooding. Urban areas as well as in the
western mountains where 1-hrly flash flood guidance is between 1.5-2
inches would be areas most vulnerable to flash flooding. Squall line
will pivot northeast until late this evening. Threat of severe and
localized hydro will continue through that period before FROPA
results in more rapid SW->NE clearing. Exception will be in the
mountains of southeast West Virginia where upslope rain will begin
to transition/mix with wet snow overnight as temperatures begin to
cool aloft. Northwest winds will be on the increase during the
evening/overnight and become gusty but likely sub-Advisory, at
least until early Monday morning.
Cold advection, good mixing and strong pressure rises will continued
to lead to an increase in northwest wind gusts. Could envision a
need for a Wind Advisory for southern Blue Ridge for Monday from
Roanoke to Boone. Given active weather in the first 12 hrs and that
it is a late second period/early third period headline, will defer
to later guidance before considering this attm. Precip will continue
to fall in upslope areas as mainly a rain/snow mix with little
accumulation; somewhat better chance for light accumulations of snow
become more likely in western Greenbrier through Tazewell and the
mountains of NW NC after this period. Highs 40s to lower 50s.
&&
.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
As of 349 PM EDT Sunday...
Ongoing mountain -SHSN will continue to affect our western mountains
counties Monday night into Tuesday, in the favored upslope areas in
western Greenbrier County down into the mountains of northwest NC.
Factoring in forecast snow amounts from Monday leads to forecast
snow accumulations from a coating to up to 2 inches with the
greatest in the western hillsides in western Greenbrier County.
Present accumulations are below Advisory thresholds and are also
over a long stretch of time, essentially a long-duration light snow
event where any modest accumulation confined to the evening. Will
also continue to have gusty northwest winds, but general trend will
be for slow abatement into Tuesday. Low temperatures in the upper
20s to mid 30s Monday night, with highs into the 40s. Quieter
weather anticipated for Tuesday night into Wednesday with beginning
of modest warming trend into Wednesday. Lows upper 30s to mid 40s
Tuesday night, while temperatures rebound in the 60s to lower 70s
Wednesday
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 510 AM 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 /20Z SUNDAY THROUGH FRIDAY/...
As of 115 PM EDT Sunday...
Poor flying conditions expected through the 18z TAF period,
especially from 18 to 03z due to the potential for
thunderstorms. Storms will be capable of damaging convective
outflow and low-level turbulence/microbursts. Indicated +SHRA
through the aforementioned period when showers and/or
thunderstorms are most likely. See specific TAFs for timing. Best
chance for severe thunderstorms is along and east of the Blue
Ridge, especially for Danville and potentially into Roanoke and
Lynchburg. Storms expected to take shape in a linear fashion and
bring potentially heavy rainfall. Indicated MVFR ceilings with
MVFR-IFR visbility. Winds will be east-southeast to southeast
10-15 kts with gusts to 20-25 kts.
Powerful cold front will move east between 03-06z with skies
beginning to clear in the Piedmont to VFR but remain MVFR with
lingering upslope showers. Expect a gusty wind shift to west
with FROPA and an eventual continued veer to northwest. Off and
on showers will continue until 18z in the far west, with
northwest wind gusts increasing with mixing very late in the TAF
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 349 PM EDT Sunday...
Have added Flash Flood Watch further north, which now includes
all counties west of Amherst, Bedford, Pittsylvania and Caswell
Counties line.
Main concern with possible training of multiple convective bands
over the mountains this afternoon and early evening where
guidance has between 1 to as much as 4 inches of rain in a 6-8
hour window. Rainfall rates could also be better than a couple
inches per hour if convection does indeed deepen enough
especially to the south. This similar scenario has lead to flash
flooding with past events. Some concern for convection to
perhaps limit moisture transport early on before the system
negatively tilts allowing for deepening south/southeast flow to
win out. However this only supported by limited number of
solutions with the latest GFS/ECMWF more in support of the
heaviest rain near the watch area. This could lead to some river
flooding as well into early next week so something to watch
pending locations of heavy rainfall and overall totals at this
point.
