Area Forecast Discussion
National Weather Service Columbia SC
836 PM EDT Fri Jun 19 2020

.SYNOPSIS...
An upper trough and daytime heating expected to provide
scattered showers and thunderstorms today. Upper level ridging
and warmer temperatures will be over the region for much of the
weekend along with chances of mainly afternoon and evening
showers and thunderstorms. Increasing chances of convection will
return Tuesday onward as moisture and the next frontal boundary
move into the region.

&&

.NEAR TERM /UNTIL 7 AM SATURDAY MORNING/...
Mid level shortwave moving into the CWA this evening clearly
evident on water vapor loops. Given a modestly unstable low
level environment, the forcing from the shortwave has aided
convective initiation, with widespread pulse thunderstorms,
which have evolved into a linear complex north of Columbia. The
mean west southwest flow should continue to carry the storms
off to the east and northeast for the remainder of the evening,
with convection winding down after midnight due to both diurnal
forces and the moving away of best mid to upper level support.

&&

.SHORT TERM /7 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/...
Upper level trough axis will be moving offshore during the late
morning with the upper level ridge building in Saturday
afternoon and Sunday. Although the axis will be offshore there
will still be instability and a couple weak short waves rotating
through the region so potential for mainly diurnal convection is
possible with the highest pops in the northern and eastern
Midlands where instability will be greatest and closest to the
departing trough. Thunderstorm chances will be lower Sunday as
the ridge axis moves over the region and suppresses most of the
potential. With the ridge building in temperatures will
continue rising with highs Saturday afternoon in the mid 80s to
around 90 and the low 90s Sunday. Overnight lows will be in the
upper 60s to low 70s.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
Upper level ridge will be moving east of the area and offshore
Monday evening as the next low pressure and frontal boundary
move through the central MS River Valley. Tuesday the upper
level trough will continue digging through the central US as the
surface low moves into the eastern Great Lakes and a cold front
strengthens. With southerly flow over the forecast area Tuesday
chances of convection will be increasing and the front will move
into the area on Wednesday. The front will stall over the
region Wednesday night and remain a focus for convection through
Friday. Models differ with the handling of the stalled boundary
Thursday through Friday however with the proximity to the area
expect convection to develop and have made only minor
adjustments to the forecast. Temperatures will be near to
slightly above normal through the long term.

&&

.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/...
VFR conditions are expected through the evening hours outside of
scattered thunderstorms. Some fog/stratus may develop during the
predawn hours Saturday.

Radar shows scattered convection ongoing at issuance with storms
near CAE/CUB/OGB but not much around AGS/DNL currently. Expect
storms to impact the terminals through 03z with possible IFR
vsby restrictions in thunderstorms. Convection should wane
through the late evening hours as atmosphere stabilizes.
Abundant low level moisture overnight combining with some
clearing of clouds overnight may favor another morning of
fog/stratus. Will include mention of MVFR cigs/vsbys 08z-12z
time frame but could see some IFR cigs at OGB/AGS which would be
in line with persistence and higher resolution NAM guidance.
Restrictions should lift mid morning with mixing and return to
VFR with a westerly wind developing around 5 to 8 knots.
Isolated convection again possible Saturday afternoon but
coverage is uncertain so not included in this forecast.

EXTENDED AVIATION OUTLOOK...No significant impacts to aviation
expected Sun/Mon. Increased precip chances Tue.

&&

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