Area Forecast Discussion
National Weather Service Columbia SC
125 AM EDT Sun Mar 24 2024

.SYNOPSIS...
Upper ridging builds over the area today into Monday. A slow-
moving cold front is expected move through the area during the
mid- week period with the next chance of showers. Temperatures
will begin below normal today, gradually warming to near to
above normal values through Wednesday.

&&

.NEAR TERM /THROUGH TONIGHT/...
Early this morning low pressure continues to deepen as it
gradually pulls away into the Atlantic. At the same time, a high
pressure ridge with modified polar air is building into the
southeast from the Great Lakes area, providing cool and dry
weather today and tonight. Winds are a little bit stronger than
they usually are overnight due to the tightening pressure
gradient, strong enough to necessitate a Lake Wind advisory for
the overnight hours. Winds should come down below advisory
criteria after sunrise, but it will still be a bit breezy
during the morning hours.

Skies will be mostly clear through tomorrow afternoon, but then
some high clouds will approach the CSRA by late in the day.
They should generally be on the thin side, however.

Watching the possibility of some patchy frost in the usual cold
spots as overnight temps will get down into the mid 30s. The
biggest threat would be over the northern an northeastern
sections of the CWA. Not enough confidence that the winds will
die down for a frost advisory, but this will need to be watched
during the next shift as it is not far away.

&&

.SHORT TERM /MONDAY THROUGH MONDAY NIGHT/...
After a cool start, fair with slightly warmer max temps Monday.
Upper and surface ridge axes to shift to our east. Expect
increasing high level cloud cover. Return low level flow to
provide some increasing lower cloud cover late Mon/Mon nt,
especially CSRA and S Midlands. Cloud cover to provide warmer
min temps Mon nt.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
Upper and surface ridge axes offshore Tuesday, with a front
approaching from the west. Mean upper trough to develop over the
central CONUS with SW flow aloft over our region, leading to
slow frontal movement. Low pressure also expected to develop
near the coast Wed nt/Thu. Guidance indicating a chance of
precipitation late Tuesday through Thursday night. Upper trough
to push to our east by Friday, with drier air and high pressure
moving in under a dry NW flow aloft, providing fair conditions
into next weekend.

&&

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
VFR Conditions expected to persist through the TAF period.

Northerly to northeasterly winds will continue to gust up to
around 20kts through Sunday morning before decreasing the second
half of the day Sunday as the pressure gradient weakens. winds
will also veer to a more easterly direction by late today into
tonight. Some thin high clouds are expected to move in from the
west late today and tonight as well, but they should cause no
aviation issues at the terminals.

EXTENDED AVIATION OUTLOOK...Restrictions associated with
rainfall are possible Tuesday.
