Area Forecast Discussion
National Weather Service Blacksburg VA
752 PM EDT Mon Sep 17 2018

.SYNOPSIS...
The remnants of Florence will pass east across the Ohio Valley
by this evening before exiting to the northeast of the area
overnight into Tuesday. High pressure builds in midweek with
another front working in from the north toward the weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 735 PM EDT Monday...

The flash flood watch remains for Caswell County North
Carolina and Halifax County Virginia this evening. A few bands
of showers and thunderstorms to the south of the remnant low
could bring isolated heavy rains in the east. Adjusted
temperatures with latest surface obs, their trends and shaped
towards GLAMP. Modified pops and weather with latest radar
trends and blended in HRRR. More changes later this evening.

As of 245 PM EDT Monday...

Florence remnant now passing through the lower Ohio Valley will
slide east and become entangled with a northern stream upper low
that looks to arrive from the west overnight. Residual leftover
bands to the southeast of the Florence low likely to linger over
eastern sections into late afternoon with perhaps additional showers
and isolated storms developing mountains before heading into
eastern sections after sunset despite loss of heating. These again
could produce locally heavy rainfall which may again cause an
isolated flash flood threat into this evening. Since uncertain as to
coverage later on and given saturated ground will just keep the
watch going for now and allow the evening shift to cancel early if
needed. Once these showers exit/fade will see developing northwest
flow take shape western mountains overnight behind the departing
upper system, so keeping in some higher pops northwest overnight
with less out east. Lows mostly in the 60s overall with some fog
around.

Upper trough shifts east through the region on Tuesday with
deepening northwest flow taking shape in the wake of this feature.
Forecast soundings also show quite a bit of drying aloft in the
afternoon with mainly lingering low level moisture west and across
the northeast closer to an embedded shortwave. Guidance also
indicating enough downsloping to limit instability except over the
far northeast where the latest HREF has enough coverage to warrant
at least chance pops. Elsewhere appears increasing weak subsidence
to help limit added convection with a breezy and slightly drier
afternoon in store after morning low clouds. Highs mid/upper 70s
mountains to downslope aided low/mid 80s east.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
As of 115 PM EDT Monday...

The remnants of Florence will be exiting, or will have just exited,
the region Tuesday evening. At best, there may be some isolated
showers early in the evening across the far eastern portion of the
forecast area. By Wednesday morning, high pressure will start to
work its way into the region, and become centered over the area by
Thursday afternoon. The result will be a drying period across the
area with temperatures averaging five to ten degrees above normal.

Forecast confidence in the above portion of the forecast is high.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 1225 PM EDT Monday...

A broad area of upper level high pressure will be situated over the
southeast U.S. Thursday night. This will keep the area in a
precipitation-free pattern. However, this will change heading into
Friday and Friday night as a cold front heads southeast into the
Ohio River Valley and the upper high shifts southeast into the far
western Atlantic. The result will the development of isolated to
scattered showers across southeast West Virginia Friday afternoon.
These will continue into Friday night across the same general region.

During the weekend, the cold front will continue its push south and
become stalled, and centered over our region along a west-east
orientation. Showers will increase in coverage during this portion
of the forecast. By Monday, the cold front is expected to only
make small progress south.

Temperatures during this part of the forecast will average ten to
fifteen degrees above normal through Sunday morning, then drop to
slightly above normal Monday morning. High temperatures will average
five degrees above normal through Saturday, then a few degrees below
normal Saturday and Sunday.

Forecast confidence in the above portion of the forecast is moderate.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
As of 752 PM EDT Monday...

SCT to BKN clouds this evening into tonight with convection.
One area of deeper convection is exiting our eastern counties.
Sct showers and thunderstorms have developed across the west
this evening and these will travel eastward tonight.

Winds mainly south at 10 to 15 kts this evening will
diminish overnight into Tuesday morning.

Models are favoring most areas west of the Blue Ridge to sink
back to MVFR to IFR with fog/cigs this evening into tonight with
showers around.

Upper trough crosses the region from the west on Tuesday as the
remnants of Florence shift to the northeast. Still potential to
see a few showers beneath this passing feature, otherwise
looking at slow improving conditions as drier west to northwest
trajectory develops.

Medium confidence in ceilings,visibilities and winds during the
taf period.

Extended Discussion...

VFR conditions are then expected for Wednesday through Friday
with high pressure over the area. scattered MVFR showers will
develop on saturday.

Confidence gradually transitions to above average by Tuesday
night into the end of this week.

&&

.HYDROLOGY...
As of 1250 PM Monday...

Main concerns continue with added rainfall within bands of
showers and storms into this evening and with river
flooding into at least midweek.

However latest guidance suggests that any added heavy rain this
into this evening will be rather isolated, mainly over the
mountains and far southeast before sliding east into this
evening. This could again cause added flooding where any
heavier cores or bands develop tonight.

Otherwise major river flooding still forecast for the Dan River
from Danville east to South Boston, and minor flooding is
forecast along the Roanoke (Staunton) River at Roanoke and
Randolph. Flooding is also expected on the New River.
