Area Forecast Discussion
National Weather Service Columbia SC
626 PM EDT Fri Sep 20 2019

.SYNOPSIS...
High pressure at the surface and aloft will dominate through the
weekend into early next week. A weak cold front with little
moisture will move through the area Monday night.

&&

.NEAR TERM /THROUGH TONIGHT/...
High pressure both aloft and at the surface will result in dry
conditions through tonight due to large scale subsidence.
Calm winds coupled with mostly clear skies overnight should
lead to excellent radiational cooling conditions. Lowered
overnight low temperatures a couple of degrees resulting in
expected lows in the middle to upper 50s.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/...
Ridging will remain across the region, both at the surface and
aloft, through the early part of next week. A weak cold front
will then approach the area by Monday night. Moisture will be
limited this weekend, and the forecast is expected to remain
dry, with pops near zero. Ahead of the front on Monday and
Monday night, limited moisture once again, with any light rain
they may develop along the central Appalachians diminishing as
the airmass pushes east of the mountains. Kept the forecast with
the front dry.

Temperatures begin climbing back up above normal, with highs
during the weekend in the mid to upper 80s, then by Monday
temperatures will reach back into the lower 90s once again. Lows
expected in the lower to middle 60s.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
As the front becomes diffuse and dissipates, ridging builds
back into the area for the remainder of the week. Rainfall
chances remain low, and dry forecast will continue for now.
Temperatures will begin to climb well above normal, with the
potential for near record afternoon high temperatures by the end
of the period.

&&

.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
High confidence in VFR conditions through the 24-hr period
except for a few hours of fog at AGS and possibly OGB.

High pressure combined with a dry airmass will provide VFR
conditions through the forecast period with little in the way of
cloud cover. The one potential concern is fog at AGS and
possibly OGB during the predawn hours. Dewpoints have come up
nearly 10 degrees from yesterday and with strong radiational
cooling expected overnight think temperatures could reach the
crossover temps at AGS and therefore think MVFR and brief IFR
vsbys possible so will include in the forecast. Less confidence
at other terminals but will include a tempo group at fog prone
OGB. Otherwise, mainly clear skies throughout with light and
variable to calm winds overnight becoming light from the east on
Saturday around 5 knots or less.

EXTENDED AVIATION OUTLOOK...Brief periods of shallow fog
possible at fog prone AGS and OGB through the extended period.

&&

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