.DISCUSSION...
As of 135 AM Thursday...

KEY MESSAGE 1... Frost Advisory remains in effect until 9 AM this
morning. Patchy frost is possible again Fri morning over the
northern Coastal Plain, where areas of fog may also develop

The Frost Advisory remains in effect for the Piedmont, western
Sandhills, and portions of the northern Coastal Plain until 9 am
this morning. Temperatures over these areas are expected to hover in
the low to middle 30s by daybreak, promoting potential frost
formation. Currently, areas of stratus and light stirring has kept
most central NC in the 40s. But these high clouds should become less
widespread into early this morning, allowing good radiational
cooling by sunrise.

For tonight into early Fri, guidance, specifically the HRRR, HREF,
and RAP, is starting to pick up on the potential for fog over the
northeast Piedmont and northern Coastal Plain. The setup features
overall clear skies compared to the past few days, calm winds, and
rising dewpoints into the low 40s. These conditions will promote
radiation fog via more favorable crossover temperatures. In
addition, we cannot rule out some patchy frost over the typical
cooler spots of the Piedmont (Siler City, Roxboro) and northern
Coastal Plain. Another Frost Advisory may be needed for a portion of
the area tonight into early Fri as a result.


KEY MESSAGE 2... Fire weather concerns will remain elevated through
early next week 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 at least the middle of next week.  A weak cold will try to
slip south through the Mid-Atlantic states on Saturday but will will
most likely not make it into central NC as the aforementioned ridge
will build across the southern US.  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. A cold front is
forecast to move into the central US by the middle of next week,
which will cause  winds will gradually become southwesterly and a
little stronger.  However, there will also better moisture return
and higher RH to potentially offset any potential fire weather
issues.


KEY MESSAGE 3... Near record warm temperatures expected Tue/Wed.

Low-level thicknesses are forecast to exceed 1400m by the middle of
next week, some 40-45m above normal.  This would result in highs as
much as 15-20 degrees above normal, approaching record levels
Mon/Tue. This level of early-season heat could be dangerous,
especially to those vulnerable to heat.

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
As of 600 AM Thursday...

There is high confidence in VFR conditions to start the TAF period.
High clouds will be the main story today and this evening with an
east to northeasterly flow of 5-8 kt. Overnight tonight, dewpoints
are expected to rise, in an environment with calm winds and clear
skies. This will promote the potential for radiation fog as
crossover temperatures rise to the upper 30s to lower 40s. The best
chance for fog (40-50 percent) is at RWI, but this cannot be ruled
out at RDU/FAY (30 percent). For now, the highest confidence of IFR
is at RWI.

Outlook: After some potential fog Fri morning, VFR should prevail
through early next week.
