.SYNOPSIS...
High pressure over the southeast will bring moderating
temperatures to the area through Thursday. A strong front will
approach from the west on Thursday, resulting in the next chance
of precipitation for the region. A brief cool down behind the
front on Friday, will be followed by warmer conditions into the
weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1206 AM EST Tuesday...

Key Message:

1) Dry with moderating temperatures.

High pressure over the southeast will bring a southwest flow
into our area through tonight. This will allow for temperatures
to rebound from the arctic chill of the past couple of days, and
we will start to see any snow cover melt off.

With mainly sunny skies today, temperatures will be closer to
normal for mid December, with 40s areawide, except some upper
30s in the mountains, and possibly reaching 50 in portions of
the NC Piedmont.

Warm front aloft and piece of shortwave energy bring increasing
clouds late tonight into the mountains. Will have lows in the
mid 20s to lower 30s, with some of the warmer lows in the
mountains.

&&

.SHORT TERM /WEDNESDAY THROUGH FRIDAY/...
As of 100 AM EST Tuesday...

Key Messages:

1) Warmer for Wednesday through Thursday, much colder Friday for
the mountains.

2) Precipitation expected areawide with a frontal system.

For mid week, weak troughing aloft remains in place initially,
but is replaced with a deeper trough developing Thursday night
into Friday. While the triple point low remains well north of
the area, a number of fronts will affect our region beginning
Thursday. We will be in the the warm sector Thursday, but plenty
of cloud cover and precipitation will result in highs in the
40s and 50s. A pre- frontal trough and cold front push through
Friday, allowing for a few snowflakes to mix in for the
mountains, with quite chilly weather/gusty winds expected
Friday. Most spots should get around a third to a half inch of
rain, with light snow possible for the western mountains, but
generally less than an inch mixing in with rain.

Confidence in the above weather scenario is moderate.

&&

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
As of 100 AM EST Tuesday...

Key Messages:

1) Warmer for the weekend into early next week.

2) Chance of showers for the weekend.

High pressure builds in from the west for Saturday, and a warm
front lifting to the north should bring warmer temperatures
for the mountains, with the entire area seeing highs in the mid
40s to low 50s again. A cold front swings through late Saturday
into Sunday bringing some light rain to mainly the mountains.
Given additional CAA and colder overnight temperatures, some
freezing drizzle is possible in the higher peaks late Sunday
night into Monday morning. This is more likely than freezing
rain as the dendritic growth zone dries out. Tuesday should be
another moderate temperature day, with some possible mountain
showers due to a passing upper level system.

Confidence in the long term is moderate.

&&

.AVIATION /05Z TUESDAY THROUGH SATURDAY/...
As of 1211 AM EST Tuesday...

VFR expected throughout the entire 24 hour TAF period.

Low level wind shear is expected during the early morning 06-10z
across parts of the mountains as a strong westerly low level
jet increases across the region, with surface wind speeds
trending lighter.

Confidence in the above aviation scenario is high.

.EXTENDED AVIATON OUTLOOK...

VFR expected through Wednesday. Rain chances increase areawide
Thursday which could bring sub- VFR cigs/vsbys, with rain/snow
showers Thu night. Lingering sub-VFR Friday in the mountains
with VFR east, becoming VFR Saturday areawide.
