.DISCUSSION...
As of 125 AM Wednesday...

KEY MESSAGE 1...  Patchy frost remains possible for portions of
central North Carolina late tonight into Thursday morning.

The anomalous ~1040mb surface high is expected to shift eastward off
the New England coast by tonight, allowing the ridge axis to settle
more over the Carolinas. Unlike earlier in the week, this
positioning will favor a more optimal radiational cooling
environment as the pressure gradient relaxes, potentially allowing
surface winds to fully decouple and become nearly calm across most
of Central NC overnight. While low-level thicknesses are expected to
rise, the lack of wind will allow surface temperatures to drop
quickly, with lows ranging from the low-to-mid 30s across the
northern Piedmont and Coastal Plain to the upper 30s south of the
Triangle. Adding to the frost potential is a gradual increase in low-
level moisture. Dewpoints are expected to climb from the 20s into
the mid-30s overnight from east to west, providing the necessary
moisture for ice crystal development on vegetation, especially
across the Piedmont. The primary forecast uncertainty for Thursday
morning remains the coverage and thickness of the high clouds. While
the potential for high cirrus could act as a light blanket and limit
cooling, any clearing would likely result in widespread patchy
frost. Given these conditions, a Frost Advisory may be necessary for
northern and western portions of the CWA.

KEY MESSAGE 2... Fire weather concerns will remain elevated through
this weekend owing to dry conditions, low relative humidity and no
rainfall forecast in the next 7 days.

Dry westerly flow will persist across the region between a broad
upper trough over the northern US and strengthening ridge over the
gulf, limiting moisture return and resulting in a dry forecast
through early next week.  The aforementioned ridge will build across
the southern US, yielding a strong low-level anti-cyclone over the
Southeast and a favorable pattern for well-above-normal temperatures
by Saturday when forecast highs reach the mid 80s. These warm and
dry conditions, with daily afternoon RH is in the 20 percent range
will not help recent fire concerns and the statewide burn ban,
mitigated only by relatively weak winds each day under high
pressure. Winds will gradually become southwesterly and a little
stronger by early next week, but there will also better moisture
return and higher RH.

.AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
As of 620 AM Wednesday...

High confidence VFR conditions will continue across all of central
NC. The primary aviation concern is brisk northeasterly flow as a
dry air mass remains in place. Expect clear skies or thin high
cirrus and no restricted visibilities for the 24 hour TAF period.

Surface winds will remain around 10kts through the morning, then
increasing and becoming gusty mid morning as daytime mixing deepens.
Expect NE winds of 10-15kts with gusts up to 20kts, especially in
the afternoon hours. The strongest gusts are expected mainly at KFAY
and KRWI. Gusts will subside around sunset, with winds diminishing
into a more light easterly flow overnight.

Outlook: Dry weather and VFR conditions are expected to persist
through the upcoming weekend.
