SYNOPSIS. High pressure will prevail through the end of the week. A few cold fronts could move through early next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/. IR satellite images shows a patch of cirrus and contrails approaching from the Deep South. The cloud cover should increase through the rest of the night, especially over SE GA. The cloud cover may slow cooling rates slightly late tonight. However, temperatures appear on pace to cool to the mid-30s inland to around 40 along the coast.

High pressure will remain near the Florida-Georgia border overnight as a weak lee-side trough forms across the western Carolinas. The boundary layer is quickly decoupling early this evening with some spots across interior already reporting calm winds. Calm/light winds will eventually work into the coastal counties over the next few hours. Temperatures will drop quickly this evening within a strong radiational cooling regime. High clouds will begin to move into the area after midnight, but it is unclear exactly how thick these will be. However, some tempering of the radiative process is likely and this will have to be watched closely. Most statistical guidance members have been running a bit too warm over the past several nights and this will likely be the case again tonight. Generally favored the cooler ECMWF-MOS numbers as they tend to verify the best in radiational cooling regimes. Lows will range from the mid-upper 30s inland to the upper 40s/lower 50s near the coast and Downtown Charleston.

SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY/. At the sfc, high pressure will become centered across the Southeast United States Wednesday, then persist through Friday. Aloft, a zonal flow will generally prevail with a weak h5 shortwave quickly shifting across the region Wednesday, followed by slight ridging heading into early weekend. The overall pattern will support dry and warming conditions as southwest sfc winds prevail under a downsloping wind component. In general, afternoon highs should reach the upper 60s/lower 70s Wednesday, lower-middle 70s Thursday, then middle-upper 70s (warmest well inland) Friday. Overnight lows will also trend warmer, even with clear skies in place. In general, low temps should range in the low-mid 40s inland to upper 40s/lower 50s near the beaches Wednesday night, then mid-upper 40s inland to low- mid 50s at the beaches Thursday night.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/. Dry high pressure will likely prevail into Saturday before a cold front moves through the local area Saturday night. However, limited moisture/forcing should preclude rain chances. High pressure should then return briefly until another cold front possibly moves through the area Monday/Monday night. Once again, moisture supply will be limited, favoring dry conditions across land, but a few showers can't be ruled out along coastal South Carolina. Temps should be above normal through at least the first half of the weekend with highs peaking in the low-mid 70s Saturday, before returning to near normal post fropa Monday and Tuesday.

AVIATION /06Z WEDNESDAY THROUGH SUNDAY/. VFR conditions expected through the 6Z TAF period.

Extended Aviation Outlook: VFR conditions are expected at KCHS/KJZI/KSAV terminals into Friday, while a low chance of sub- VFR conditions are possible Saturday night as moisture increases with a passing cold front. VFR conditions should then prevail to start off next week.

MARINE. Tonight: High pressure will prevail across the Southeastern U.S. Southwest winds in the evening will veer to the west by daybreak Wednesday. Sustained winds should generally average 5-10 kt. Seas will average 1-2 ft within 20 nm and 2-3 ft for the GA waters beyond 20 nm.

Wednesday through Sunday: Conditions will remain well below small craft advisory levels through Saturday with west/southwest winds in place, but a slight uptick in wind speeds (15-20 kt) is expected Saturday night into Sunday with a passing cold front. Southerly flow should return early next week with gradually building seas (3-5 ft) ahead of an approaching cold front.

FIRE WEATHER. Relative humidity values are expected to fall to 25-30% across inland southeast Georgia Wednesday afternoon. However, southwest winds will be relatively light, peaking around 10 mph for these locations. Given the lack of significant wind, a Fire Danger Statement is not needed.

TIDES/COASTAL FLOODING. Tides will be elevated later this week due to astronomical influences from the New Moon. Minor coastal flooding will be possible during the morning high tides as early as Friday, mainly around Charleston.
