Area Forecast Discussion
National Weather Service Columbia SC
654 PM EST Sat Mar 6 2021

By Sunday, strong high pressure will begin building into the
area, keeping the area dry and bringing warm temperatures to the
region through next weekend.


As the upper shortwave pushes further off the coast, skies will
continue to clear through the night across the southern half of
the forecast area. Cold air advection will continue as the
center of the surface high behind the front remains west of the
area through daybreak. In addition, a low-level jet will help to
keep boundary layer winds up a bit, keeping ideal radiational
cooling conditions from developing. Kept overnight lows in the
upper 20s and lower 30s.


A positively tilted upper trough along the East Coast will move
offshore on Sunday. High pressure aloft over Western Gulf of
Mexico will gradually build into the Southeast U.S. by the
middle of next week. Temperatures will start off below normal
for early March on Sunday with colder air behind the upper
trough, but warm to near or above normal levels by mid week. Dry
weather will persist across the region.


High pressure aloft will remain over the Southeast U.S. through the
end of next week. Expect much above normal temperatures for mid
March. The ensembles diverge on the timing of breaking down the
high aloft as strong upper trough moves into the Mid
Mississippi River Valley next weekend, but for now warm and dry
weather appears to persist through Saturday.


VFR conditions likely through the 24 hour TAF period.

Expect clear or mostly clear skies through the period. Dry air
will hinder fog formation overnight. Slight concern at fog prone
AGS due to higher dewpoints in the CSRA. It still seems
unlikely that fog will cause significant aviation impacts at AGS
but we can`t rule out shallow ground fog developing early Sunday

An upper level trough will move over the region tomorrow with a
tightening pressure gradient. North winds should pick up in the
morning around 10 kts, becoming NW in the afternoon with gusts
from 15 to 20 kts possible. As surface high pressure moves into
the Deep South late in the day, the pressure gradient will
weaken and gusts should subside.

EXTENDED AVIATION OUTLOOK...Significant impacts unlikely
through Thursday.
