.DISCUSSION...
As of 225 PM Sunday...

KEY MESSAGE 1...Another round of fog and low clouds during the
Monday morning commute.

Similar to this morning, and thanks to ongoing light wind, high
dwpts and minimal dwpt depressions, much of central NC will see a
few hours of locally dense fog and low clouds during the Monday
morning rush hour commute.  The highest dwpts and thus best chance
for said fog will be east, so look for best coverage of dense fog
mainly to the south and east of Raleigh. Similar to this morning,
the fog should burn off by 9:30 AM.

KEY MESSAGE 2... High heat and humidity return quickly this week,
beginning Monday and peaking Wednesday through Friday.

Aloft, the ~595 dam mid-level anticyclone will build eastward into
and settle over the region through at least mid-week. Disturbances
in the northern stream may help push the ridge south and west toward
the end of the week, with the trough amplifying across the East
Coast over the weekend. At the surface, a lee trough may remain in
place across the area, while Bermuda high pressure ridges wwd across
the region, with a sly component to the wind across much of the area
through at least mid-week. The trough may amplify across the region
late-week. Low level thicknesses of 1440+ m expected across the area
Wed-Fri. Temperatures should moderate through mid-week, with highs
in the mid/upr 90s for Wed-Fri (10+ degrees above normal). Some
locations could reach 100 degrees Wed and Thu. Lows in the 70s
expected through much of the week. Heat index values of 100-110 are
possible across much of the area Tue-Fri, highest Wed and Thu. Given
the prolonged period of heat with little relief overnight, the WPC
Experimental Heat Risk continues to show Major to Extreme risk of
heat-related impacts across central NC Tue-Fri. Heat advisories may
be needed should the forecast hold. Expect largely dry weather
through Thu, though a stray shower/storm during the aft/eve cannot
be completely ruled out. Chances for storms increase toward the
weekend as the mid/upr trough amplifies over the region.

.AVIATION /10Z MONDAY THROUGH FRIDAY/...
As of 730 PM Sunday...

Through 00Z Tuesday: Fog is possible again late tonight through
Monday morning, especially from RDU to FAY and RWI given no change in
the airmass over central NC since last night.  Confidence in fog is
lower at GSO and INT where model guidance keeps skies clear.

VFR is then expected areawide by mid-morning.

Outlook: Mainly dry weather and VFR conditions through mid-week.
Afternoon and evening thunderstorms may return during the latter
half of the week.
