.DISCUSSION...
As of 205 PM Monday...

KEY MESSAGE 1... Minimal rain for for the remainder of today. Areas
of dense fog possible tonight/early Tuesday morning.

The sfc cold front has slid south of central NC this morning, with a
surge of cool nely flow pushing south across the southern Piedmont,
Sandhills, and southern Coastal Plain. Expect temperatures to
continue to drop through the remainder of today and into this
evening.  Rain chances have come down considerably as the stratiform
rain shield remains mostly up into VA. Can`t rule out a few Trace to
a few hundreds of an inch across the NC/VA border, but overall QPF
will be quite limited.  Any convection down in SC should remain
south of central NC at this point.

The main concern is the potential for areas of dense fog tonight.
The most consistent signal has been for areas in the northern
Piedmont and Coastal Plain, but some guidance extends this down to
RDU or even further south and east.  Regardless, those across the
NC/VA border should be prepared for possible slower travel for
tomorrow`s morning commute.

KEY MESSAGE 2...  A chance of showers/isolated thunderstorms
Wednesday afternoon and evening.

A weak cold front will move through the region Wednesday night.
Ahead of the front, a band of showers and possibly a few embedded
thunderstorms are expected. Rain is expected to start late Wednesday
afternoon and last into Wednesday night. With most of the rain
expected around or just after sunset, instability should be weak,
which will lessen the risk of stronger or severe storms. However,
adequate shear parameters may allow for a few embedded stronger
cells. This will especially be true in the Triad where the front
will approach first as there will be a better chance for more
instability. In terms of rainfall, the latest LREF, which includes
the European and Canadian ensembles and the GEFS, is suggesting
around 0.25 to 0.5 in of rain over central NC. If any stronger
storms develop, a few deterministic models are suggesting there
could be a few swaths of up to 1 inch of rain.

KEY MESSAGE 3... Hot and dry weather returns this weekend into next
week.

After Wednesday`s frontal passage, surface high pressure will build
into the region through the end of the week and then shift offshore
on Saturday. At the same time, a mid-level ridge will be in place
over the region. Once the high shifts off the southeast coast and
the ridge is centered over the region, southerly flow will prevail
and allow for increasing temperatures. Saturday, central NC will
have maximum temperatures in the mid-to-upper 80s, increasing to the
upper 80s to low 90s on Sunday and Monday. This pattern is expected
to continue into at least mid-week, leading to an extended period of
warm to hot temperatures expected.

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
As of 150 AM Tuesday...

24 hour TAF period: Fairly high confidence shallow IFR/LIFR fog will
develop in the next couple hours, mainly across the north, the
question is how far south and east it will occur. Highest confidence
at KINT/KGSO, lowest at KFAY. Any fog that does develop should
quickly burn off with sunrise, with a return to VFR by 13Z expected.
Calm to light nly to nnely winds expected through daybreak,
increasing and becoming sly, first at KINT/KGSO this morning and
gradually veering to sly elsewhere through the aft/eve.

Outlook: VFR conditions will prevail through Wed, with additional
flight restrictions and rain expected with the passage of another
frontal system from Wed aft into Thu morn. VFR conditions should
return Thu, albeit with gusty winds, and remain VFR through Sat.
