.DISCUSSION...
As of 300 AM Sunday...

KEY MESSAGE 1... Locally dense fog and probably widespread low
overcast this morning, then showers and isolated storms focused over
the Piedmont and Sandhills this afternoon

Cyclonic, nnwly flow aloft will prevail across the Middle and South
Atlantic states through tonight, between a slow-moving cyclone over
the Canadian Maritimes and a ridge over the srn High Plains. Within
that nnwly flow regime, at least a couple of impulses over the mid
and upr MS Valley will progress across the Southeast.

At the surface, a synoptic front was analyzed at 06Z from far nern
NC nwwd across srn VA, then generally wwd through KY and srn MO.
This boundary will continue to settle swwd, in backdoor fashion,
though NC today.

Light wind, initially clear skies, and abundant near surface and
soil moisture will favor the development of areas of low stratus and
fog/mist this morning. While related ceilings and visibility
restrictions will lift and disperse through midday, an area of
deeper, 850-700 mb centered moisture stretching across the Virginias
and lwr Oh Valley will progress ssewd into cntl NC through the
afternoon. This area of moisture will coincide with the progression
of the backdoor surface cold front and result in the development and
deepening of showers and isolated storms, focused over the Piedmont
and adjacent Sandhills, where diurnal timing will allow for
relatively stronger heating and destabilization. An isolated strong
to severe storm or two will be possible over the far wrn/srn
Piedmont during the afternoon, before the front and moisture and
instability axes continue wswwd into the Upstate of SC and far swrn
NC tonight.


KEY MESSAGE 2... Several days of near normal temperatures starting
today, followed by an increase back above normal mid/late week

Temperatures today through Tuesday should remain near normal as a
mid/upper level longwave trough slowly shifts off the east coast.
Cooler and drier air should filter into the region from the north
through the day today, allowing high temperatures this afternoon to
rise into the low 80s north to the upper 80s south. Temperatures
should remain in the 80s through at least Tuesday. As ridging starts
to build over the region mid-week, highs should return to the 90s on
Wednesday or Thursday. The chance of rain early this week after
today will be generally low each day, with an isolated diurnal
thunderstorm possible each afternoon/evening especially late week as
warming is occurring and moisture is returning to the region. It
looks like another cold front may pass through central NC Thursday
night which brings the next best chance of showers to the region.
Temperatures may then cool off a few degrees, potentially back into
the 80s, for next weekend.

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
As of 100 PM Sunday...

MVFR conditions linger at this hour across portions of central NC,
mainly western and southern areas, and isolated IFR cigs are found
in and near a cluster of storms now just ENE and E of the CLT metro
area and tracking southeastward. This activity is along a frontal
zone stretching WNW-to-ESE across W and S NC, and while it should
stay largely SW of our TAF sites, these storms may pass near FAY
this afternoon, and a second round of scattered storms now over the
N mountains of NC may skirt just W and S of INT/GSO toward early
evening. Regardless, a shower is possible prior to 00z at any TAF
site. These sct-bkn MVFR cloud bases should continue to slowly lift
through the afternoon, however INT/GSO/RDU/FAY could see a few more
hours of MVFR cigs. As the surface frontal zone settles further to
our S and SW, with drier air slowly moving in from the N and NE,
shower/storm chances will push to our S and SW. This will result in
prevailing VFR conditions late tonight through Mon, although our far
SW may see a period of MVFR cigs tonight 09z-13z. Surface winds will
stay mainly from the NE through Mon.

Looking beyond 18z Mon, VFR conditions should prevail across central
NC through much of Thu with generally dry weather. Shower/storm
chances start to ramp back up late Thu, and stay elevated through
Fri, as a cold front approaches from the NW.
