Area Forecast Discussion
National Weather Service Raleigh NC
345 PM EDT Tue Sep 5 2017

.SYNOPSIS...
A cold front and pre-frontal surface trough will approach from the
west tonight, and move across central NC on Wednesday. High pressure
will follow and build from the mid MS Valley east to the middle
Atlantic states Thu and Fri.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 345 PM Tuesday...

Little change to the near term forecast. Still appears that
scattered convection will occur across central NC late this
afternoon through this evening with a few showers persisting into
the overnight. The atmosphere has become slight-moderately unstable
with sfc based CAPE values 3000-3500 J/kg over the coastal plain and
Sandhills. While instability is presence, effective bulk shear is
marginal, and mainly across the northern counties. Thus, appears
most of the convection will remain pulse type in nature. Downdraft
CAPE values hovering around 1000 J/kg, so isolated strong/damaging
wind gusts possible with the stringer convection. In addition, other
parameters hint that the storms may produce frequent lightning.

Bulk of convection will occur in the 5 PM-9 PM time frame with
gradually weakening trend expected thereafter. However, the approach
of a mid level s/w and attendant sfc front will sustain a few
showers overnight, especially across the west. Shower coverage will
likely increase by daybreak across the western Piedmont as the sfc
front gets closer. A warm and muggy night expected with minimum
temperatures in the upper 60s nw to the low-mid 70s east-se.

&&

.SHORT TERM /WEDNESDAY AND WEDNESDAY NIGHT/...
As of 345 PM Tuesday...

A mid level s/w and attendant sfc cold front will enter the western
Piedmont Wednesday morning, then drift slowly east through the day.
This feature will be the focus for scattered-numerous showers and
storms. Potential will exists for a strong or severe storm or two,
primarily along and east of highway 1 as MLCAPE values between 900-
1200 J/kg and bulk shear a respectable 35-45 kts by afternoon. Model
CAPE may be overdone, however, as expecting considerable cloudiness
and showers Wednesday morning across the region, inhibiting
insolation. This should limit the ability of the lower half of the
atmosphere to destabilize, and prevent storms from reaching severe
criteria. If this is the case, then will need to lower the severe
storm threat Wednesday morning.

The passage of the front Wednesday morning may cause temperatures to
cool Wednesday afternoon across the Triad region. Elsewhere, high
temperatures will likely be achieved by early afternoon when
scattered convection will begin to affect most places.

The front will exit the region by early Wednesday evening with a
notable decrease in shower coverage west-to-east. Cooler drier air
will infiltrate behind the boundary, leading to partial clearing
across the Piedmont overnight. May see some fog develop but
confidence not high enough to mention in the forecast at this time.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
As of 150 PM Tuesday...

Thursday through Saturday: Expect a relatively dry period through
Saturday night with the surface front off the Mid-Atlantic coast and
high pressure over the region. Highs should remain in the mid 70s to
around 80 degrees, while lows will range from mid 50s NW to low 60s
SE.

Sunday through Tuesday: The forecast gets a bit more exciting toward
the end of the weekend with the approach of Irma, however detail on
the track and resultant impacts are still uncertain and will likely
remain so for at least a couple more days. That being said, it's
never too early to review your hurricane action plan and to be
prepared should Irma impact NC. Expect gradually increasing cloud
cover, winds and chances for convection Sunday through Tuesday,
regardless of the track Irma takes. As the confidence in the track
increases, so will confidence on timing and location of the heaviest
rain and strongest winds. Temperatures will also be impacted by
Irma, but for now expect highs generally in the 70s and lows ranging
from upper 50s NW to mid 60s SE.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
As of 140 PM Tuesday...

Scattered convection and associated MVFR parameters will develop in
vicinity of the TAF sites across central NC this afternoon through
early evening. Otherwise, expect VFR conditions away from the
convection. Aviation conditions will begin to deteriorate after
midnight as the atmosphere moistens in advance of an approaching
cold front. Scattered showers and a few thunderstorms may occur
overnight, though the probability of scattered convection will
increase Wednesday as the fronts gets closer to central NC. After
06z Wed, expect periods of MVFR ceilings across central NC, and more
so after 15Z Wednesday. Shower and thunderstorm coverage and
intensity will increase Wednesday afternoon as the front drifts east
across the region.

The adverse aviation ceilings will gradually improve west-to-east
Wednesday night, especially after 03Z Thursday. VFR parameters
expected areawide Thursday morning, lasting through the weekend.
