River Flood Warning 10, NWS Raleigh, NC

AREA FORECAST DISCUSSION
National Weather Service Raleigh NC
405 PM EST Thu Feb 6 2020

.SYNOPSIS...
A stationary front remains along the Virginia-North Carolina border
and will be swept out as a cold front tracks across the Carolinas
tonight. A secondary cold front will follow and cross the region
Friday morning, bringing strong winds. The weekend should be mostly
dry.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 320 PM Thursday...

A line of severe thunderstorms has traveled across most of the
forecast area. Hail reports have been isolated, with most of the
damage that's been reported coming from straight-line winds. The
portion of the line that is east of Raleigh is still severe, with
severe thunderstorm warnings in effect. Meanwhile, the part of the
line extending southwest of Raleigh is not quite as strong, with
winds "only" in the 40-50 mph range. There is still plenty of rain
to come, although much of the severe threat should be gone at this
point. Synoptic and high-resolution models had the line coming
through during the mid-afternoon and evening hours, not during the
late morning and early afternoon. The models still have not caught
up to the timing of the line, so confidence is low in how long rain
will persist. Have gone with a slow trend decreasing showers through
the evening into the overnight hours. Overnight lows will be in the
50s, with lowest values to the west behind the cold front.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
As of 320 PM Thursday...

A secondary cold front will swing through the region early in the
morning, bringing at least a slight chance of showers to most
locations. Showers should be east of the region by the afternoon
hours. Behind the secondary cold front winds will really be on the
increase considering strong mixing and a tight pressure gradient.
The GFS is a bit more aggressive with higher wind values, with the
BUFKIT momentum transfer algorithm showing winds just above advisory
criteria, around 45-50 mph, while the NAM momentum transfer
algorithm shows winds just below advisory criteria, between 35-45
mph. With today's weather, did not get as much of a chance as normal
to interrogate model data, and have decided to hold off with any
sort of wind advisory at this time. Counties to the east are under a
wind advisory, and cannot rule out that a wind advisory may need to
be issued later. Winds will come down by sunset, and skies will
clear out overnight. Temperatures will only rise a few degrees
during the day with highs remaining in the 50s, while lows will
plunge to the freezing mark Friday night.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
As of 440 AM Thursday...

An upper level shortwave should will approach and cross the area on
Saturday and Saturday night bringing a small threat of some spotty
light rain on Saturday afternoon across the Triad and much of the
area Saturday night. The system is moisture starved and only light,
scattered precipitation is expected. The thermal profile is cold
enough such that snow is not out of the question toward the daybreak
hours, but have kept the forecast all rain for now given the
marginal temperatures. This is supported by SREF forecasts of
partial thicknesses near the snow/indeterminate location on the
nomogram. Highs on Saturday will range in the upper 40s to lower 50s
with lows in the lower to mid 30s on Saturday night.

Fair weather is expected for Sunday through early Monday as high
pressure extends into the region. A slow moving cold front will
approach on Monday and move into the region on Tuesday before a
northern stream trough moves across the OH Valley and Mid Atlantic
on Wednesday. The result will be a chance of light rain or showers
on Tuesday and Wednesday. Highs on Monday will range in the lower to
mid 60s and moderate into the 60s to around 70 for Tuesday and
Wednesday. -Blaes

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
As of 1250 PM Thursday...

A line of strong to severe thunderstorms has moved east of INT/GSO
and is expected to affect other terminals in the next 6 hours. Winds
to 50 kt are possible and the line of thunderstorms has a history of
producing tornadoes. As of 18Z, all terminals are under a tornado
watch. The storms are expected to bring a brief period of LIFR
conditions, with baseline MVFR/IFR conditions ahead of and behind
the line. In fact, INT/GSO will likely remain under LIFR conditions
with lots of low level moisture and northeasterly winds. Elsewhere,
conditions will gradually improve through the evening and overnight
hours, with VFR conditions expected by morning.

Outlook: A secondary cold front will cross the region with scattered
showers, a scouring of any preceding low clouds and fog, and
following very strong and gusty southwesterly surface winds Fri
morning. A passing mid to upper level disturbance and related
surface frontal system will cross the region with an associated
chance of light rain and MVFR conditions late Sat into early Sun.

&&

.HYDROLOGY...
As of 405 PM Thursday...

Area of moderate to heavy rainfall will continue this evening,
particularly over the southern and eastern Piedmont, Sandhills and
southern coastal plain. As much as of 2-4" of rain have fallen in
the Piedmont, and an additional inch is possible this evening.  1-3"
will be possible for area south and east of the Triangle. This
rainfall over the headwaters of expansive basins will push many
mainstem rivers near or over flood stage, including parts of the
Yadkin, Haw, Cape Fear, and Neuse.  Points along the Haw River are
already seeing a rapid response this afternoon and will reach minor
to moderate flood stages. River flooding may extend well into the
weekend over eastern sections, as this rainwater flows through the
tributaries and downriver.

...A STRONG THUNDERSTORM WILL AFFECT EDGECOMBE AND WILSON COUNTIES
UNTIL 715 PM EST...

At 612 PM EST, Doppler radar was tracking a strong thunderstorm near
Wilson, or 17 miles west of Farmville, moving northeast at 55 mph.

Half inch hail and wind gusts up to 40 mph will be possible with this
storm.

Locations impacted include...
Rocky Mount, Tarboro, Wilson, Elm City, Princeville, Sharpsburg,
Pinetops, Stantonsburg, Black Creek and Macclesfield.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Seek shelter in a nearby building or vehicle. Wind gusts as high as
40 mph are capable of knocking down tree limbs and blowing around
trash cans, potted plants, lawn furniture and other light outdoor
objects.

Locally heavy rain will quickly reduce visibility and result in
ponding of water on roadways, standing water in low lying areas, and
minor flooding of creeks, streams, and areas of poor drainage.
Drivers are urged to slow down and use extra caution to avoid
hydroplaning, especially in urban areas where prolonged heavy rain
can quickly lead to flooding.

A Tornado Watch remains in effect until 700 PM EST for central North
Carolina.
