.SYNOPSIS... A cold front moves south of the forecast area tonight, bringing cooler and drier air by Monday. Mainly dry conditions are expected during the upcoming work week, with below normal temperatures to start, gradually warming as the week goes on.
&&
.NEAR TERM /UNTIL 8 AM MONDAY MORNING/... Key Message(s):
- Cold front is moving through the southern Midlands. - Isolated showers and storms remain possible along and south of the front.
Cold front has pushed through the central Midlands of SC, and is moving through the southern Midlands and into the CSRA this evening. The drier air associated with the front is still lingering slightly, but has moved into the Pee Dee and the northern Midlands. Dewpoints in the lower 60s and upper 50s along the SC/NC border will continue moving southward overnight and should setting into the central Midlands by morning. Areas along and near the front however will still see moisture overnight, and can not rule out isolated to scattered showers and storms in those locations. Winds gusty north of the front at times overnight. Low temperatures drop into the low to mid 60s by morning.
&&
.SHORT TERM /8 AM MONDAY MORNING THROUGH TUESDAY NIGHT/... Key message(s):
- Cooler and dry conditions expected early this week with high pressure building into the region.
- Breezy conditions expected on Monday
Anomalous surface high pressure will continue to build into the region early this week with persistent northeasterly flow. This will continue to filter drier and cooler air into the forecast area on Monday. The frontal boundary will remain stalled along the coast and deeper moisture should stay to our east with PWATs ranging from less than inch in the western Midlands to 1.2-1.3 inches in the eastern Midlands. An inverted trough is expected to develop on Tuesday in response to an approaching upper trough which should tighten the moisture gradient across the Coastal Plain and while we are keeping a dry forecast at this time, it is possible if that gradient shifts inland a bit more for some showers to possibly impact the eastern Midlands Tuesday and Tuesday night.
NAEFS has low level temperatures in the 10th percentile which should support below normal temperatures during this period with highs in the upper 70s to lower 80s and lows ranging from the upper 50s to lower to mid 60s.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/... Key message(s):
- Continued dry weather expected
- A warming trend is expected mid to late week
A generally dry and warming forecast is expected through the extended period. Ensemble guidance shows the upper pattern remaining fairly unchanged with a mean trough across the eastern part of the country with a reinforcing shortwave trough moving from the Ohio Valley to the east coast on Thursday. This will push another reinforcing dry frontal boundary through the region to the coast with another surface high pressure reinforcing the dry air mass. Ensemble PWATs remain below normal through the period and this should support the continued dry forecast. Temperatures are expected to be warming back to near normal through the end of the week with highs in the 80s and lows in the 60s. There are hints of lowering upper heights next weekend which could signal a slight cooldown again.
&&
.AVIATION /00Z MONDAY THROUGH FRIDAY/... VFR conditions this afternoon with some scattered showers, mainly east of TAF sites.
A cold front has moved through cae/cub, and is situated just south of OGB, but north of ags/dnl. This front will continue to push southward through the night, clearing all locations by morning. Winds will become gusty at times behind the front as it moves through, and eventually the drier air will filter across the entire forecast area. Guidance trending more towards vfr conditions at cae/cub/ags/dnl overnight and into Monday, and confidence is higher in those locations due to the drier air moving in. Lower confidence at ogb where moisture may linger, especially just east of ogb along the coastal plain tonight. Guidance does show a higher probability of seeing a period of mvfr/ifr ceilings for a period overnight there beginning around 04z and lasting through the night. All sited vfr on Monday. Winds will become gusty through the day behind the front Monday.
EXTENDED AVIATION OUTLOOK...A cooler and drier air mass will settle over the region early this week behind the front.

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