.SYNOPSIS...
Low pressure over southeastern Virginia will move off the Mid-
Atlantic coast tonight. High pressure will extend over the area
through late week.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 132 PM Wednesday...
* Patchy fog development possible tonight
Surface analysis and satellite imagery reveal the slow-moving area
of low pressure is still rotating counterclockwise over southeastern
VA. A large area of stratus remains around the system, with the
western edge of the low clouds from Alamance to southern Wake to
southern Wayne Counties. As a result, a quite variable range in
temperatures are present, with low to mid 60s in the NE, to as warm
as the low 80s near Wadesboro. Highs should top out in the low 80s
in the W and SW to upper 60s in the far NE. Radar continues to show
some lingering light rain or drizzle across the northeast Piedmont
and northern Coastal Plain with the wrap around moisture. These
light rain or sprinkles can be expected off and on over the next few
hours in the NE before the low departs off the VA coast.
Tonight, the aforementioned low should exit of the Mid-Atlantic
coast, leading to gradual clearing of the low cloud deck. Lingering
low-level moisture and some patchy mist should then favor the
development of patchy fog, primarily for areas along and north of US-
64 of the Piedmont and Coastal Plain. Areas that saw rain as well
this morning over the northern Piedmont may be more susceptible to
fog development overnight to early Thu morning. Lows should drop
into the upper 50s to low 60s.

.SHORT TERM /THURSDAY AND THURSDAY NIGHT/...
As of 132 PM Wednesday...
* Warmer with 80s area-wide
Weak high pressure will be centered over the region in the wake of
the departing low, beneath broad troughing at mid-levels over
northern GA/SC. The airmass warms significantly from Wed, with
conditions typical for late June. Highs should return above normal
area-wide with low 80s NE to upper 80s SW. Clear skies and light
winds Thu night should favor lows in the upper 50s to low/mid 60s.
&&
.LONG TERM /FRIDAY THROUGH TUESDAY/...
As of 104 AM Wednesday...
Very warm to hot Friday and Saturday.
No significant rain expected.
Upper ridging will be in place bringing dry and warm weather Friday
and Saturday. A weak upper level trough is expected to develop well
west of the central Appalachians Sunday lingering into Tuesday.
However, other than a small chance of showers close to the coast
Sunday and Monday, central NC is expecting none. As for
temperatures, the warmest temperatures will likely be on Friday and
Saturday when mid to upper 80s are forecast. Lows will be in the
60s. Slightly cooler air will arrive Sunday with a backdoor front.
Highs Sunday through Tuesday should be in the upper 70s to mid 80s
north-central to south. Lows in the mid 50s to lower 60s.

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
As of 132 PM Wednesday...
A mixture of VFR and MVFR conditions will start the TAF period. An
area of low pressure over southeastern VA is continuing to promote
lingering MVFR ceilings at RWI and partially at RDU. This area of
low pressure will gradually shift off the Mid-Atlantic coast
tonight. This should favor MVFR ceilings gradually improving at RWI
by early this evening, though cannot rule out that these MVFR
ceilings linger longer than expected in the latest forecast.
Otherwise, VFR should largely take over until later tonight.
Lingering low-level moisture in the wake of the departing low
combined with winds becoming calm will favor areas of low stratus
and possible fog Thu morning. As of now, the best chance of fog
appears at RDU, GSO, and possibly RWI. Confidence was not high
enough to show prevailing fog at any terminal, however. Fog would be
more favored at RWI if the low ceilings can clear out. Conditions
should return to VFR at all terminals by mid-morning Thu, though may
linger a tad longer than currently expected at RWI. West to
northwest winds today will become light tonight and Thu.
Outlook: Largely VFR conditions are expected through Monday.
