Area Forecast Discussion
National Weather Service Columbia SC
142 PM EDT Wed Sep 19 2018

.SYNOPSIS...
High pressure will build in from the west through Friday
bringing dry and warm conditions. Moisture will return early
next week as an onshore flow develops.

&&

.NEAR TERM /THROUGH TONIGHT/...
High pressure centered over the TN Valley will build into the
region through tonight. Subsidence associated with the ridge
will provide sunny skies and above normal temperatures this
afternoon. Dewpoint temperatures this afternoon have dropped
into the lower to middle 60s in most locations across the area.
Low temperatures tonight will fall into the mid and upper 60s
under mainly clear skies.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
High pressure at the surface and aloft will control our weather
for the end of the work week. Increasing H5 heights and overall
atmospheric subsidence will lead to mostly clear skies and
continued above normal temperatures.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
High pressure aloft moves off the Southeast U.S. coast this
weekend which allows for an onshore flow into the Carolinas and
Georgia. The region may see diurnal showers and thunderstorms
early next week. Above normal temperatures will continue through
Tuesday.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
High confidence in VFR conditions through the 24-hour TAF
period outside of possible patchy early morning fog.

Surface high pressure building into the region from the west
will promote dry conditions through Thursday. Visible satellite
imagery this afternoon shows few to scattered cumulus
development. Skies should clear around sunset. Surface winds
will be out of the north at around 6 knots or less through
sunset becoming calm overnight. Cannot rule out brief patchy
fog early Thursday morning mainly at the fog prone terminals,
AGS and OGB, although confidence is too low to include at this
time. Winds will pick up by late morning on Thursday out of the
east at 5 to 8 knots.

EXTENDED AVIATION OUTLOOK...An onshore flow should bring
increased low-level moisture with an increased chance of late
night and early morning stratus and fog beginning Friday.

&&

.HYDROLOGY...
Record rainfall fell across the Pee Dee basin, with over 20
inches in parts of Chesterfield County. Flooding is occurring
along the Great Pee Dee River at Cheraw and will continue
through Thursday night.the low 70s.

&&

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