Area Forecast Discussion
National Weather Service Columbia SC
131 PM EST Mon Jan 16 2017

.SYNOPSIS...
High pressure along the mid Atlantic Coast will keep partly to
mostly cloudy skies and a little cooler air over the forecast
area through tonight. The high will move away from the region on
Tuesday with southerly flow on the backside of the high bringing
warmer weather back to the area. A cold front and associated
moisture will be in the area Tuesday night and Wednesday.
Unsettled weather will close out the week into the weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
Although conditions have improved slightly...wedge conditions
remain entrenched across the Midlands with the CSRA just
outside the wedge enjoying sunny skies. With the clouds
temperatures across the Midlands remain in the mid 50s to around
60...however in the CSRA where skies are mostly clear
temperatures are in the upper 60s to mid 70s. Current satellite
imagery shows breaks in the clouds in the Midlands so expect
the wedge to continue slowly eroding through the afternoon with
temperatures across the Midlands warming several more degrees.
Clouds will return early tonight as an inversion develops and
light southeasterly flow keeps plenty of moisture in place.
Expect another round of low clouds and fog to develop early
tonight and continue through the sunrise hours Tuesday morning.
With the extensive lower clouds overnight lows tonight will
generally be in the upper 40s to lower 50s.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
High pressure aloft over the Eastern Gulf of Mexico reasserts itself
over The Midlands and CSRA during the middle of the week for the
middle of the week for temperatures 15 to 20 degrees above
climatology.  We can expect areas of late night and early morning
fog and a chance of showers in the northern Midlands Tuesday Night
near a stationary front.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
A very active southern branch of jet stream will push two systems
into the Southeast U.S. late this week into early next week.  The
first system arrives Thursday Night into Friday with the second
system forecast for Sunday into Monday.  Expect unsettled weather
and for the most part above normal temperatures during this time
period.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Restrictions expected to dominate much of the TAF period for
CAE/CUB/OGB...with restrictions expect tonight at AGS/DNL.

Wedge conditions remain over CAE/CUB/OGB with VFR conditions at
AGS/DNL. With the wedge solidly in place expect restrictions to
continue into the mid to late afternoon hours at CAE/CUB/OGB
before lifting to VFR. Main concern for the period will be the
overnight hours as an inversion will develop and with low level
moisture in place and light southeasterly flow again confidence
is high for fog and stratus redeveloping. Expect conditions to
return to IFR/LIFR at all sites during the early morning and
sunrise hours. Winds will be southeasterly at 5 knots or less
through tonight...then become southerly around 5 knots by mid
morning.

EXTENDED AVIATION OUTLOOK...Significant CIG/VSBY restrictions
expected Tuesday morning. Showers and associated restrictions
possible Tuesday night through Friday.

&&

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