What forecasters said that day

The local office's own words before this flash flood 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 flash flood warning went out at Oct 10, 4:32 PM EDT, 1 hour 57 minutes earlier.

Area forecast discussion, Oct 10, 4:32 PM EDT, 1 hour 57 minutes before
Area Forecast Discussion
National Weather Service Blacksburg VA
432 PM EDT Wed Oct 10 2018

.SYNOPSIS...
Wet weather is expected tonight and especially Thursday as Hurricane
Michael moves through the southeast U.S. A cold front will cross the
area by Thursday evening and shift Michael well offshore. A period
of gusty northwest winds is expected in the mountains and foothills
Thursday afternoon and evening. Cooler high pressure builds in to
start the weekend.

&&

.NEAR TERM /THROUGH THURSDAY NIGHT/...
As of 330 PM EDT Wednesday...

Most significant change in terms of headlines with the afternoon
forecast package was with the expansion of the Flash Flood Watch
north and west, to now encompass an area from the I-81 corridor
eastward. Portion of the Watch which now includes the NW NC
mountains, Wilkes County, Grayson, Smith and Wythe Counties is in
effect until Thursday early evening. The portion of the Watch which
previously included just the NC Piedmont, foothills and Southside
now adds the the New River Valley and Roanoke County is in effect
from 8 AM Thursday until late Thursday night. Finally, the final
segment of the Watch includes the southern Shenandoah Valley
eastward to include the central VA counties north of the Roanoke
River. This part of the Watch begins Thursday morning and ends late
Thursday night. This was done to better time when heavy rainfall is
expected to begin.

We still are contending with periods of moderate to at times heavy
rain showers associated with tropical moisture infusion forced
upslope in regime of southeast low-level flow. While not reaching
overly excessive totals, nonetheless rainfall amounts to this point
have proven to overproduce given highly efficient tropical warm rain
processes, as regional radar shows this rain axis extending from
central WV southeastward into northern SC, with greatest radar
returns across northern SC. High resolution guidance continues to
pivot this axis north to northeast over the next 3-5 hours, so the
threat for heavy rain at times will still continue especially for
areas along or east of the Blue Ridge. Couldn't rule out minor flood
issues through mid-evening, but at the least this rain will only
serve to prime the ground for the bigger slug of heavy rain which
comes Thursday associated with Michael. Later tonight though, model
guidance agrees that we'll begin to get into a relative minimum in
rain chances and rain amounts, as we await the heavy rain associated
with Michael's closest approach.

For the latest on Michael's intensity and forecast track
information, please refer to the latest advisories from the National
Hurricane Center. Michael is forecast to eventually turn northeast
across the central Carolinas into southeast Virginia and the
Tidewater area on Thursday, its northeast turn aided by a strong
cold front which is now working its way through the Mississippi
River Valley. Michael's interaction with this cold front is expected
to lead to an expected westward spatial expansion of Michael's heavy
rain shield Thursday, and this has essentially played out in today's
12z NWP guidance. Expected local impacts for the region include the
following:

(1) Heavy rain, potential flash flooding and rises along smaller
streams and creeks to mainstem rivers. Heaviest rains should occur
through Thursday before clearing west-east Thursday late afternoon
into Thursday evening in the east.

(2) Post-Michael gusty to potentially damaging northwest winds
Thursday afternoon into early morning Friday from the Blue Ridge,
the immediate foothills counties and back westward to include the I-
81 corridor.

Heavy rains should begin to progress northeastward starting earliest
in the mountains of NW NC and the mountain empire around early
Thursday morning, and then continue north and northeast the NC/VA
Piedmont, Southside starting Thursday mid-morning and continuing
into central VA by late morning. Area averaged rain forecast ranges
from an inch to inch and a quarter in southeast WV and Tazewell
County, 1.5-2 inches across the I-81 corridor into central VA, and
then 2 to 5 inches across the southern Blue Ridge, the NC
Piedmont/foothills and into Southside. These values closely resemble
WPC's latest rain outlook. Localized higher amounts are possible,
particularly the further south/east one goes. Overall confidence on
rain totals is moderate to high on where the greatest rain totals
will be observed, but is lower on exact magnitudes. See the Hydro
section for more detail.

As heavy rain begins to skirt eastward Thursday late afternoon into
early Friday, focus will then shift toward strong and gusty
northwest winds across the NC/VA mountains and into the immediate
foothills areas. Of concern is that saturated ground in conjunction
with this rain will lead to an environment which will make weak/dead
trees easier to be felled. Very strong pressure rises and north-
northwesterly 850 mb jet of 40-50 kts off the GFS will likely
support a period of 45-50 mph wind gusts Thursday late afternoon
into evening in these areas. To avoid any potential concern with
confusing messaging with what really is more of a non-tropical wind
hazard, haven't issued any wind headlines as yet in collaboration
with NWS GSP, but it's quite likely that at least impact-based wind
headlines will be needed at some point for the potential for
tree/powerline damage and hazardous travel through mountain passes
such as I-77/Fancy Gap. Have opted to message in the HWO for now.
May also need to consider such headlines for the Piedmont as well
but have highest confidence in the mountains.

Forecast confidence is overall moderate on the heavy rain and flood
threat, and is moderate to high on the post-Michael wind threat.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY/...
As of 330 PM EDT Wednesday...

Focus Friday will be on post tropical storm conditions with
rush of wind and cooler temperatures in the wake of Michael.
Primary wind flow will be out of the northwest with dewpoints
tanking into the 30s/40s as cool/dry October airmass finally
makes an entrance.

Temperatures Friday and into the weekend will resemble something
closer to the climatological norm...a change that will stun
folks into making an about-face for a jacket for outdoor
activities. Weekend as a whole looks relatively dry with a
couple of disturbances moving up through the Ohio Valley
promising to cast a few clouds and possible showers to the WV
mountains.

In general, the upper air pattern will begin to shift into a
Fall pattern, with broad troughing over the eastern 2/3rds of
the country this weekend, trending toward a much deeper long
wave trough by the middle of next week. During the transition,
first in a series of short waves will pass through the base of
the trough, the first wave being the remnants of the Pacific
Hurricane Sergio which will pass through the Ohio Valley Sunday.
The wave that follows Monday will be of Canadian origin.

&&

.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
As of 400 PM EDT Wednesday...

October finally feels like, October.

A large scale upper trough is forecast to reside over the
eastern 2/3rds of the country the entire week, amplifying by
mid-week as series of short waves digging south from Canada
resulting in a fairly extensive cold intrusion to much of the
central and eastern CONUS. Model concensus is for some
unseasonably cold air (yep summer to winter) to overtake areas
which were basking in unseasonable warmth, and in some cases
extreme enough to permit the frozen form of precipitation across
the upper Mid-West and Great Lakes into parts of New England
where 850 mb temps plunge low enough to support snow.

For the central Mid-Atlantic it will certainly feel like
October, if not favor some November sort of temperatures which
would be permissible for frost formation for parts of the
forecast area...especially the mountain valleys. Precipitation
chances appear somewhat limited, but there will be opportunities
for showers associated with each passing shortwave trough,
Monday favoring a day for showers, and then again toward mid
week. Monday might actually turn out to be a little wetter than
forecast, models trending toward some over-running associated
with a frontal passage.

&&

.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
As of 213 PM EDT Wednesday...

Poor flying conditions generally will predominate the 18z TAF
period, but especially for the Thursday portion of the TAF as
the circulation associated with Michael makes its closest
approach.

Current MVFR/IFR cigs/visbys will remain relatively stable with
periods of 2-6 SM SHRA through the afternoon and early evening
as tropical moisture is lifted upslope. Toward the evening
hours (after 02z), steady rain showers should taper off to
intermittent unrestricted showers, but lingering MVFR-IFR
ceilings will likely continue across the TAFs. Southeast winds
6-8 kts should predominate from the afternoon into the evening.

Heavy rains associated with Michael's northern circulation then
begin to progress north/northeast toward the pre-dawn hrs of
Thursday morning in the NC mountains, and through the rest of
the 18z TAF period across the remainder of the airspace. Look
for initial VFR visbys to decrease to MVFR-IFR most everywhere
as these rain bands move northeast, and may at times be
LIFR vsby at Danville. Ceilings likely to be in the IFR range.
In addition, while surface winds should be east to northeast
around 4-8 kts, very late in the TAF period northwest winds
along mountaintops will increase rather sharply as Michael
passes, lead to a likely period of mechanical turbulence
especially within and just downslope of the Blue Ridge.

Confidence is above average for sub-VFR most of the period, but
lower on timing heaviest rains Thursday and how low ceilings go
tonight into Thursday.

Extended Discussion...

Heavy rains associated with Michael will begin to shift
eastward late Thursday afternoon, but northwest winds will
continue to increase Thursday night into midday Friday leading
to gusty northwest surface wind conditions and areas of
mountain turbulence.

Conditions will improve back to VFR on Friday behind the front,
then VFR over the weekend.

&&

.HYDROLOGY...
As of 300 PM Wednesday...

An inflow of deep tropical moisture will introduce the possibility
of both flash flooding and later river flooding in the Wednesday
afternoon through Friday time frame.

A first round of heavy rain not directly associated with Hurricane
Michael has been very impressive across northwestern North Carolina,
especially parts of Watauga County today. Radar is grossly
underestimating the rainfall in this area due to a combination of
beam overshooting and tropical air mass characteristics. Some rain
gages In Watauga are showing up to 5 inches during the day today,
much of it falling in about 6 hours. The Watauga River and upper New
River stream gages are rising very rapidly this afternoon and will
be rising above flood stage shortly. The area remains under a Flood
Advisory and a Flash Food Watch has already been issued for this
region. Flood Warnings may be required

After a lull in rainfall the tonight, the coverage and intensity is
expected to increase again on Thursday late morning/early afternoon
with the approach of what is expected to be (by that time) Tropical
Storm Michael. Weather forecast models are still indicating some
variability in rainfall amounts depending on the track and speed at
which the storm pushes across the Carolinas, but the most likely
scenario still indicates QPF of 2 to 5 inches across the Southside
of Virginia and the Piedmont of North Carolina, where the flash
flood watch continues. The highest end of this range falls in the
Dan River basin where guidance already suggests moderate flooding is
the most likely occurrence. But shifts in QPF will heavily affect
forthcoming river forecasts and both minor or major are also
possible depending on how much and where it falls. 1 to 2 inches of
rain seems most likely across the upper Roanoke, James, Greenbrier
and middle New river basins where river flooding will likely be
minor if any. Again, modest shifts in the rainfall pattern could
substantially affect these river forecasts, so remain attentive.

Convective bands with high rates of rainfall within a tropical
environment will obviously present an enhanced flash flood threat,
with the Weather Prediction Center calling for a slight to moderate
risk of excessive rainfall during the Thursday to early Friday
timeframe, mainly across the southeast one-third of our forecast
area.
