Area Forecast Discussion National Weather Service Columbia SC 131 AM EDT Wed Oct 4 2023

SYNOPSIS
Dry high pressure and upper ridging continue through Thursday.
Expect clear to mostly clear skies, light northeast winds, and near normal temperatures over the area during this time. The pattern breaks down on Friday as a trough sets up over the eastern CONUS. Near to above normal temperatures this week fall to below normal values this weekend following a frontal passage.

NEAR TERM /UNTIL 6 AM THIS MORNING/
The upper ridge begins to slowly inch eastward over night while the surface high remains stationary, keeping the dry air mass in place. The HRRR smoke model does show the periodic smoke to continue overnight, which may cause some haziness at times. Lows are forecast to be a couple degrees warmer tonight than the past couple nights, with temperatures dipping down to the mid 50s to around 60s.

SHORT TERM /6 AM THIS MORNING THROUGH THURSDAY NIGHT/
Another benign day Wednesday with an almost carbon copy of Tuesday's discernible weather. The high pressure ridge will nudge east and broaden over the Mid Atlantic and southern New England. Surface high pressure will be shifting away from the area but will continue to be broadly across the eastern US.
Enough moisture in the lower levels for some fair weather cumulus, otherwise clear. Temperatures will be similar, perhaps a degree warmer, to those on Tuesday. On Thursday, the pressure gradient at the surface will tighten over the southeast and onshore moisture transport will slowly increase. The upper low centered well east of the Florida coastline will struggle to move even as the upper trough starts to near the Appalachians.
The shallow moisture and lack of forcing will keep the area dry once again, though perhaps less sunshine in the late afternoon.

LONG TERM /FRIDAY THROUGH TUESDAY/
The cold front will set up over the eastern CONUS and guidance continues to keep the passage mostly dry with the exception of maybe a few showers in the CSRA Friday night and in the north and west on Saturday. Any rainfall amounts should be minimal.
ECMWF and GFS are still in quite a bit of disagreement on the timing of the front and the GFS pushes drier air into our northwest counties Saturday morning. The timing of the front will greatly impact not only highs on Saturday but also lows Sunday morning. The NBM seems to be a good consensus between the to major global models and shows the stark gradient in highs that day; however, given the cooler trend seen in ensembles, may see temperatures in the low 40s both Sunday and Monday morning.

AVIATION /06Z WEDNESDAY THROUGH SUNDAY/
Pressure ridge extending into the area from the Mid Atlantic.
The air mass remains dry although near surface moisture has increased a bit. With clear skies and light winds, fog may develop toward 12z at OGB and AGS although nocturnal cooling may be more limited tonight. Some mixing noted in the boundary layer which may limit fog development. The cross-over temp is low at AGS. Large dew point depression at OGB at the moment. But forecast soundings suggest a threat along with persistence so will continue tempo MVFR/IFR fog at those sites 08z-12z.
Cumulus developing by early afternoon and winds northeast 5 to 10 knots becoming light around 00z Thursday.

EXTENDED AVIATION OUTLOOK...Late night/early morning fog possible at ags and ogb through the period.

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