.SYNOPSIS...
A dry, cool airmass remains over the region. The dry weather
continues through weekend, with slowly rebounding temperatures
across the area. Cooler temperatures and chances for rain return
toward the second half of the week due to an approaching system
from the west.

&&

.NEAR TERM /THROUGH TONIGHT/...
Key Message(s):

- Continued dry and cool.

Early this morning: Another clear, dry, and cold morning on tap
across the area with morning lows in the low to middle 30s
expected. Airmass remains dry enough with some weak surface
winds to keep frost formation patchy at best.

Today and Tonight: Much of the same, with dry airmass keeping
skies mostly clear. Temperatures may be only slightly warmer
this afternoon than yesterday, with highs closer to 60 degrees
over much of the area. Tonight will see temperatures dropping
back into the 30s. As to how low they drop, the blend seems to
have trended slightly warmer. However, with excellent radiational
cooling conditions, do expect readings below the 50th
percentile. Actually went much closer to the 25th percentile for
lows, but even that keeps lows above the freezing mark for the
majority of the forecast area. Either way, another cold night
expected.  Patch frost remains a possibility.

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
Key Message(s):

- Dry with temperatures continuing to moderate through Monday.

High pressure will be centered over the southeastern US Sunday with
weak upper ridging centered to the west of the forecast area
allowing temperatures to continue to moderate to near seasonal
average with highs in the mid to upper 60s. High pressure will
slowly shift offshore Sunday night, although favorable radiational
cooling conditions expected with the center of the high still near
the area. Lows also expected to moderate, even with the favorable
radiational cooling, in the upper 30s to around 40.

Upper level pattern becomes more amplified Monday with a digging
trough into the Northern Plains that will strengthen a surface low
over the Great Lakes. A downstream strengthening of the upper ridge
and warm advection ahead of a cold front will lead to warmer
temperatures Monday with highs mainly in the low 70s. Cold front
expected to remain northwest of the area Monday night with winds
remaining elevated and increasing cloudiness keeping lows mild, in
the mid-50s.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
Key Message(s):

- Warm Tuesday with temperatures near normal mid to late week.
- More unsettled weather towards the end of the forecast period,
  including Thanksgiving.

Continued trending towards better agreement among deterministic and
ensemble members in the cold front moving through the area during
the day Tuesday. As the trough becomes negativity tilted and
ensemble means indicate cut off upper low develops near the
Great Lakes, the surface low will be steered northeast, with
the cold front becoming more diffuse over the southeastern US.
With moisture and forcing over the area marginal, blended
guidance indicates low pops Tuesday. Have introduced slight
chance, however, with deterministic and enough ensemble member
support of receiving measurable rainfall, although amounts will
be light. Cooler airmass pushes in for midweek behind the
front, bringing temperatures to near average. Ensemble members
show a more substantial moisture increase towards the end of the
period for Thanksgiving with higher rain chances and ensemble
means indicating stronger upper forcing to support more
widespread rainfall.

&&

.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/...
VFR conditions for the entire period.

Light westerly winds early this morning, then speeds increase to
around 5 knots through the day. A return to light and variable
then occurs by sunset. Aside from that, clear skies and dry air
keep things completely VFR.

EXTENDED AVIATION OUTLOOK...No significant aviation impacts
expected.

&&

.CAE WATCHES/WARNINGS/ADVISORIES...
SC...None.
GA...None.
