.DISCUSSION...
As of 200 PM Friday...

KEY MESSAGE 1... Dangerous heat will persist and intensify across
central North Carolina through the holiday weekend.

Under a building 596dm upper ridge that has shifted east over the
heart of NC, heat has ramped up significantly today with 2pm temps
already in the mid and upper 90s.  Dewpoints are hovering in the
upper 60s and lower 70s, resulting in heat indices in the 100-106F
range at most observing sites, although some NC ECONet sites and
other non-official weather stations report values up to 110F,
especially across the Northern Piedmont and northern Coastal Plain.
The Heat Advisory and Extreme Heat Warning remain unchanged for the
rest of the day and tomorrow for the moment.  We contemplated
expanding the Extreme Heat Warning south of HWY 64, which is the
current rough delineation between advisory and warning, but we will
wait to see how high the heat indices end up this afternoon.
Tomorrow is expected to be hotter across the board, but models
indicate some drier 925mb air (evident on this mornings RNK roab)
that settles over the Piedmont and keeps heat indices at least
similar today.

Heat indices may not be as high on Sunday or even into Monday, as
the upper ridge begins a slow weakening and low-level thicknesses
nudge lower, but the cumulative impacts of multi-day highs around
100F and humid conditions will likely warrant additional Heat
Advisories.

Other heat-related points:

- Overnight lows will generally remain in the mid to upper 70s,
providing limited nocturnal recovery, allowing cumulative heat
stress to increase as the event progresses.

- The greatest concern continues to be the prolonged duration of the
heat rather than any single exceptionally hot day. Consecutive days
of excessive heat and warm nights compound impacts.

- The experimental NWS Heat Risk product indicates Major to Extreme
Heat Risk today through Monday. (wpc.ncep.noaa.gov/heatrisk)

- While isolated afternoon convection (particularly from Sunday on)
may provide localized and temporary relief, coverage appears
insufficient to significantly mitigate the overall heat hazard.

- Additional Heat Advisories will likely be needed on Sunday and
Monday.

- Finally, the highest risk will be for those without effective
cooling, individuals working or recreating outdoors, and other heat-
sensitive populations as the prolonged stretch of above-normal
temperatures continues into next week.


KEY MESSAGE 2... Mostly dry weather will persist through the
weekend, then better rain chances return to start the work week.

Apart from perhaps an isolated cell or two, the anomalously strong
blocking ridge sitting over the region through the weekend will keep
us dry and largely insulated from deep moisture flux, as bulk shear
remains very low. This ridge will finally weaken, flatten, and drift
south late in the weekend, allowing the westerlies to dip southward
as ridging builds over the Desert Southwest. One very weak mid level
trough develops from the lower Miss Valley over TN and the Mid South
Sat night, but the more prominent shortwave trough is expected to
dig over the Upper Midwest late Sat before slowly drifting over the
Great Lakes through Mon and into the Northeast Tue. The still-weak
but improving (and increasingly cyclonic) mid level flow by late Sun
into Mon should allow late-day convection over the NC mountains to
drift E into the sharpening in situ Piedmont trough, while old
outflows from anticipated convective complexes over the Midwest,
lower Great Lakes, and Ohio Valley may also push SE into the NC
Piedmont and provide a focus for convection. Shower/storm chances
appear greatest Mon/Tue, each afternoon through evening, with PW
150% of normal. Severe chances appear modest, given that mid level
flow remains under 25 kts with mostly sub-1500 J/kg SBCAPE, although
DCAPE could be significant with these expected thermal-moisture
profiles. Then, as the surface cold front affiliated with the
Northeast shortwave trough potentially dips into NC by Wed, we may
see a drop in pops back toward more climatological coverage, or at
least a push in higher pops to our southern half, but confidence in
timing of driving features within this otherwise still-weak
summertime steering flow is low.

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
As of 100 PM Friday...

TAF period: VFR conditions are expected through the 24 hour period.
Isolated storms are possible near the NC/VA border Saturday
afternoon but should remain north of TAF sites.

Outlook: Dry VFR conditions remain in the forecast through Sunday.
a cold front will approach from the northwest early next week and
bring unsettled weather.
