...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 200 AM EDT MONDAY 
FOR NORTHERN ROCKINGHAM...SOUTHWESTERN PITTSYLVANIA AND SOUTHEASTERN 
HENRY COUNTIES...

At 110 AM EDT, gauge reports indicated that flooding continues 
across the warned area as a result of excessive rainfall late Sunday 
evening, with rainfall amounts of 4-6 inches across much of the 
Martinsville area. Roads, highways, and some property remain 
flooded. Flooding is now occurring on the Smith River from 
Martinsville southward to Eden North Carolina.

HAZARD...Flash flooding caused by heavy rain.

SOURCE...Automated gauges.

IMPACT...Flooding of small creeks and streams, urban areas, 
         highways, streets and underpasses as well as other drainage 
         and low lying areas.

Excessive rainfall over the warned area will cause mud slides near
steep terrain. The mud slide can consist of rock, mud, vegetation and
other loose materials.

Some locations that will experience flooding include...
Eden...
Stoneville...
Mayfield...
Oregon Hill...
Price...
Ruffin...
and Draper.

Flood waters are moving down the Smith River from Bassett to 
Martinsville to Eden North Carolina, then eventually into the Dan 
River at Wentworth. The flood crest should reach Eden early this 
morning.

Other creeks and streams that are likely in flood include the 
following streams and drainages... Mayo River, Hardys Creek, Surry 
Martin Branch, Marrowbone Creek and Machine Creek.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.

When it is safe to do so, please send your reports of flooding,
including mudslides or flooded roads, to the National Weather Service
by calling toll free at 1...8 6 6...2 1 5...4 3 2 4. Reports and
pictures can also be shared on the National Weather Service
Blacksburg Facebook page and on Twitter.

...THE FLASH FLOOD WARNING FOR 
NORTHERN ROCKINGHAM...SOUTHWESTERN PITTSYLVANIA AND SOUTHEASTERN
HENRY COUNTIES WILL EXPIRE AT 200 AM EDT MONDAY...

High water and flooding continue across much of southern Henry 
County and northern Rockingham County at this hour. However, as the 
rain has ended, the threat of flash flooding has diminished 
considerably.  Thus the Flash Flood Warning will be allowed to 
expire and will be replaced with an Areal Flood Warning for the 
remainder of the night.

Several roads remain closed across southern Henry County and rivers 
are rising, including the Smith River which has risen to flood 
during the last couple of hours at Bassett, Martinsville, and Eden. 
River rises can also be expected to near minor flood on the Dan 
River at Wentworth.

Avoid travel through this region if at all possible until water 
levels have receded.  It is very difficult to assess water and river 
levels at night.  Do not drive into areas where water covers the 
road and heed any road closures ordered by local officials and law 
enforcement.

Area Forecast Discussion
National Weather Service Blacksburg VA
742 PM EDT Sun May 24 2020

.SYNOPSIS...
A weak cold front will extend from Pennsylvania into the Carolinas
tonight and Monday. High pressure will cover the region Tuesday and
Wednesday with a continued daily chance of thunderstorms, especially
in the mountains. Another cold front crosses the area Friday
and Saturday with more precipitation.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 730 PM EDT Sunday...

Ongoing warnings, both severe and flash flood, at this time
with main convective activity shifting toward the NC border but
still scattered showers across the mountains.

Previous valid discussion
As of 250 PM EDT Sunday...

Upper ridging over the western Atlantic will lead to rising 500MB
heights over the Carolinas and Mid Atlantic states tonight and
Monday.  Surface winds have turned to the northeast behind a
backdoor cold front that had reached the Roanoke and New River
Valleys. Bufkit showed a shallow stable layer that stays below
850MB. A the leading edge of a layer of low cloud behind the front
had filled in over Buckingham and Appomattox counties and was
approaching Lynchburg. These clouds will continue to advance tonight
and fill in much of the area east of the Blue Ridge by morning.

Surface winds already easterly well out ahead of that stratus. So
the localized upslope along the Blue Ridge in combination with that
subtle short wave that is sparking the current thunderstorms in West
Virgina may lead to isolated thunderstorms, but expect better
coverage from BLF to TNB where the back door front is providing
more surface convergence and the environment is more unstable.

The low clouds in the foothills and piedmont will dissipate during
the morning. Expecting enough sun in the afternoon to bring
temperatures into the 70s. Isolated to scattered thunderstorms in
the afternoon will be confined to west of the wedge, mainly west and
south of Bluefield and Boone.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
As of 210 PM EDT Sunday...

An upper ridge will sit along the east coast and drive moisture into
the area, mostly in the mountains in the western section of the CWA.
Daily chances for thunderstorms in this period, with best potential
for formation in the mountains of NW NC and SW VA on Tuesday and
Wednesday. A small wave will track north from the Gulf along the
flow from the ridge, bringing wider chances at showers and storms
Thursday for the entire area.

It will feel quite springlike this period, with highs in the 70s and
lows in the 50s/60s. It will still feel humid as we still try to dry
out from last week's soak.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
As of 200 PM EDT Sunday...

The upper level ridge over the eastern part of the country combined
with a Bermuda high off the coast will keep a warm and moist flow of
air over the Appalachians and central mid Atlantic region through
the end of the week. With a good supply of deep moisture will have
to watch for the potential of heavy rainfall.

Ensemble guidance indicates that the upper ridge will be flattening
in time, which will allow a weak front to sag into the area and
continue our chances for showers/thunderstorms into the weekend.
High pressure will finally start to build down from the upper
midwest with the promise of some drier conditions heading into the
first part of next week.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
As of 730 PM EDT Sunday...

Scattered to numerous showers and a few thunderstorms this
evening but starting to diminish. Any airports that get
impacted by any of these storms will have MVFR ceilings and
visibility.

A weak backdoor cold front will push into the central
Appalachians tonight. This will allow for the leading edge of a
shield of stratus that was just east of KLYH to advance into
KROA/KBCB/KLWB and KDAN. Ceilings will lower to LIFR/LIFR
overnight with MVFR to IFR fog. Slight improvement is expected
in the afternoon.

Average confidence.

Extended Aviation Discussion...

Upper-level ridging will dominate the Mid-Atlantic region this week.
Showers and storms with MVFR conditions are possible mainly in
the afternoon/evening. No widespread or long term periods of
inclement weather are expected at this time. fog with IFR-LIFR
visibilities in the mornings with brief and isolated sub-VFR
ceilings/visibilities is expected each overnight.

A cold front comes through the area on Friday and Saturday
bringing a more widespread chance of precipitation and MVFR or
lower flight conditions.
