.SYNOPSIS...
Sub-tropical high pressure will extend from near Bermuda to the
Carolinas throughout the week.

&&

.NEAR TERM /TODAY THROUGH TONIGHT/...
As of 155 AM Wednesday...

Lower chance of PM storms, but remaining hot and humid.

The highest moisture levels will gradually shift a bit west and
north today with the upper ridge building in the southeast U.S. from
off the SW Atlantic. This should limit the convection to widely
scattered PM activity. The highest probabilities will be along the
SE Coastal Plain (sea breeze) and tucked up along the Blue Ridge.
Highs will be in the upper 80s to lower 90s with partly to mostly
sunny afternoon skies. Lows generally in the lower 70s west and mid
70s east.

&&

.SHORT TERM /THURSDAY AND THURSDAY NIGHT/...
As of 310 AM Wednesday...

Hotter and humid weather continues...

Widely scattered PM thunderstorms.

The westward extension of the Bermuda high will extend over NC on
Thursday. There will be a bit of a suppression of convection
chances. However, widely scattered thunderstorms are still expected
during the late afternoon through mid-evening mainly over the
Piedmont. Highs will warm into the lower to mid 90s. Lows will be in
the mid to upper 70s.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
As of 1245 PM Wednesday...

* Another stretch of hot weather with heat indices peaking in the
  100-109 range across central NC, highest across the Sandhills and
  Coastal Plain.

The center of the mid-level anti-cyclone will gradually migrate
westward across the Southeast US, Deep South, and Lower MS Valley
through the middle of next week. Central NC will generally remain
under the high or the nrn periphery of it through the extended
forecast period. A mid level s/w trough will pass to the north Sat
night/Sun, with a trailing disturbance Sun night/Mon. At the
surface, W-E elongated high pressure will stretch from the ern Gulf,
across FL and east over the Atlantic toward Bermuda through the
weekend. To the north, a lee trough will linger over central NC.
This trough may finally shift ewd as a cold front tries to move in
from the north early-mid next week. A weak low may develop within
the trough and lift newd across the area over the weekend, somewhat
coincident with the s/w aloft passing to the north. The best chances
and greatest coverage of showers and storms will be over the weekend
with the s/w passage and ahead of the approaching front from the
north. Otherwise, cannot rule out diurnally driven convection,
especially along the VA border, through the end of the week. The
bigger concern will be the extended period of hot, humid weather,
with little overnight relief, through at least the weekend. Highs
will range from low 90s NW to mid/upper 90s south and east, with
heat index values in the 100 to 109 range along and east of US-1.
Overnight lows in that area may only dip into the mid 70s, further
exacerbating the heat risk, especially over the Sandhills and srn
Coastal Plain. Some relief is possible next week if the front moves
into the area and high pressure is able to build in.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
As of 130 PM Wednesday...

Scattered showers and a few storms are developing across the
Sandhills and southern/central coastal plain counties and will
persist into the early evening before gradually dissipating. Brief
periods of MVFR to IFR restrictions are most likely at KRWI and
KFAY, with possible impact at KRDU. KGSO and KINT terminals should
remain dry.

Compare to recent nights and mornings, model guidance indicates a
lower potential for sub-VFR restrictions from stratus overnight into
Thursday morning. However, favoring persistence, a tempo group for
MVFR ceilings will be included at all TAF sites between 10-14z Thurs.

Ceilings will lift to VFR by mid to late morning Thursday as daytime
heating lifts and mixes out any low ceilings. SWLY winds will
increase by the afternoon, with occasional gustiness of 15 to 20 kts.

Scattered showers and storms to redevelop Thursday afternoon and
lingering into the evening hours, with the highest coverage expected
across the western terminals (KINT and KGSO).

Outlook: Sub-tropical high pressure over the western Atlantic will
support a typical summertime pattern of isolated to scattered
afternoon and evening thunderstorms, along with patchy late night
and early morning fog and stratus through the weekend.
