AREA FORECAST DISCUSSION
National Weather Service Raleigh NC
150 AM EDT Sun Mar 28 2021

.SYNOPSIS...
A warm front will lift northward across central NC this morning. A
strong cold front will surge east across the state this afternoon
and early evening. Cool and dry high pressure for Sunday night and
Monday. Yet, another storm system will affect the region mid-week,
followed by the potential for freezing overnight lows by Friday and
Saturday.

&&

.NEAR TERM /TODAY THROUGH TONIGHT/...
As of 138 AM Sunday...

...Windy and warm ahead of a strong cold front with S-SW winds at 20-
30 mph with gusts to over 40 mph...

...An organized line of severe thunderstorms expected to cross the
region during the afternoon and early evening Sunday...

...Damaging wind gusts is the main severe threat, but large hail and
isolated tornadoes are also possible...

The primary forecast challenges today are timing of the main line of
thunderstorms and the severe threat.

WAA showers/thunderstorms were already developing and overspreading
upstate SC into our western Piedmont of NC. This convection is
elevated above the stable near surface layer extending over the
western Piedmont of NC into upstate SC. Note the light NE flow over
much of western NC into SC, where the low level in-situ CAD
conditions were in place. The warm front extended the developing low
pressure over the Mid-Mississippi Valley region eastward across
southern TN, northern GA, SC, and southeastern NC. This front is
expected to slowly lift northward this morning as the first round of
convection remains elevated. This initial round of showers/storms
should move from the Charlotte area NE into the Triad and Triangle
Areas between 06z and 10z, or so. Then, this round should lift on
into VA toward sunrise. Again, this convection will be tame in
comparison to the potential convective event later today.

Even the hi-res models have timing differences for the expected pre-
frontal or frontal convection later this morning into the afternoon.
The HRRR is the quickest to bring a line eastward out of the
Mountains and through much of the Piedmont by early to mid
afternoon. Other guidance including the GFS and old run of the EC
are slower and more intense with our convection during peak heating.

Given the intense thunderstorms upstream over much of northern
Tennessee (moving rapidly ENE) now, with additional strong to severe
storms back along the new low pressure and cold front extending near
Memphis to west of Nashville, there is the potential for either of
these solutions to verify at the current time.

It appears for now that the most likely scenario is for an intense
line of thunderstorms will push east across our region (from early
afternoon NW and late afternoon in the east). Since the initial
convection this morning should have moved north, the warm advection
and mixing in the warm sector should overtake most of central NC by
late morning. The low level winds just above the surface will
increase to 50-60 knots. The best heating should occur in the south
and east where 70s to lower 80s will again be expected. If the
heating is realized, with the projected surface dew points in the
lower to mid 60s, the resultant MLCapes would reach or exceed 1500
J/kg. The fast moving front/line of convection would be able to tap
into some of the very strong winds to potentially produce surface
gusts in the stronger storms to 60+ mph. If the in-situ CAD
conditions remain in place over the NW-N Piedmont longer and/or if
the convection arrives late morning or more quickly per the latest
HRRR, then this would reduce the severity of the damaging wind
threat there.

Otherwise, the line should quickly exit the I-95 corridor by early
evening. This will be followed by breezy NW winds this evening,
clearing skies, and cooling temperatures into the mid 30s to mid
40s by early Monday morning.

&&

.SHORT TERM /MONDAY AND MONDAY NIGHT/...

Surface high pressure will quickly move across the area on Monday,
with a much cooler and dryer air mass filtering into the area. This
will result in a return to dry weather, with high temperatures in
the 60s.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
As of 640 PM Saturday...

Tuesday through Wednesday: Surface high pressure will quickly move
across the area on Monday, with a much cooler and dryer airmass
filtering into the area. This will result in a return to dry weather
for the start of next week, with high temps back in the 60s. As the
surface high shifts further offshore Monday night into Tuesday a mid
level disturbance will lift northeastward from the northern Gulf of
Mexico spreading showers back across the area Tuesday morning into
Wednesday. However, confidence on the track of the system and timing
and where the surface front will be remain low, along with when we
will see precip spread back into our area. The 00Z and 12z/27 medium
range guidance continues to trend slower with spreading precip back
into the area from the south. Have delayed PoPs till late Tuesday
and into Wednesday. Will need to keep an eye on this system as we
will likely see some sort of in-situ CAD develop, and possibly
storms (possibly strong to severe). Temps during this period will be
challenging as well, largely driven by the precip and actual track
of the system. For now will go with highs generally in the 60s for
Tuesday, with mid 60s to mid 70s on Wednesday (low confidence
though). Low are expected to be in the 40s and 50s.

Wednesday night through Friday: The mid/upper level flow pattern
will amplify mid week as a deepening trough drives another strong
cold front through the area Wednesday evening and into early
Thursday, along with band of showers and thunderstorms, some of
these storms could be severe depending on the amount of instability
we have (poor diurnal timing). Dry weather is expected to return by
Thursday afternoon with much colder air will filtering in behind the
cold front to end the work week, with some freezing temperatures
possible Friday and possibly Saturday mornings.

&&

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
As of 150 AM Sunday...

Areas of IFR to LIFR conditions with low clouds and fog can
be expected through 12z-14z. Scattered showers and thunderstorms
are also expected through 12z. A strong and gusty SW wind at 20-25kt
will gust to near 40kt this afternoon out ahead of a cold front. The
front should be accompanied by a line of convection, timing of which
should be early afternoon in the Triad, mid afternoon around KRDU,
then late afternoon KFAY to KRWI. This could change.

After the front passes, NW winds at 20kt will gust to 25kt for a
time this evening. A return to VFR conditions are otherwise
expected.

Outlook: VFR conditions in high pressure will follow until the next
frontal system and cold air damming --with rain and LIFR-IFR
conditions-- affects cntl NC Tue-Wed.
