SYNOPSIS. High pressure will build across the region today, then prevail this weekend through the middle of next week.

NEAR TERM /THROUGH TONIGHT/. Deep dry air continues to move into the region in wake of a cold front. PWat from the 12z KCHS RAOB around 1.15 inches has since dropped below 0.75 inches per SPC mesoanalysis. Lower humidity values and full sunshine will make for a pleasant early fall day. High temperatures are forecast to reach the upper 70s to around 80 across most locations. Ongoing forecast was on track, so no notable changes were made with the early afternoon update.

Tonight: Temperatures should cool off steadily this evening, with 60s inland by sunset. The center of sfc high pressure is expected to build over the southern Appalachians by late tonight, spreading across the CWA. The combination of a clear sky and light north winds will yield steadily cooling temperatures tonight. Using a blend of MOS, low temperatures are forecast to range from the low 50s inland to around 60 degrees along the coast.

SHORT TERM /FRIDAY THROUGH SUNDAY/. High pressure will spread across the region this weekend along the southern edge of a broad mid-lvl trough extending across the Midwest and Northeast regions. Given the pattern, considerably drier and slightly cooler conditions are expected across the Southeast United States to start off the weekend. Despite sunny conditions, a northerly wind will keep highs around 5 degrees below normal initially on Friday, generally in the upper 70s-lower 80s. Friday night lows should also remain considerably cooler than normal with a favorable radiational cooling in place. In general, many locations will dip into the low-mid 50s inland to low-mid 60s at the beaches. A gradual warming trend is then anticipated as a light northwest wind develops along the southern edge of the sfc high on Saturday, followed by a more favorable downsloping wind setup across the region heading into Sunday. In general, highs should range in the lower 80s Saturday afternoon, then low-mid 80s Sunday afternoon. Low temps will be a few degrees warmer as well, but still averaging in the mid-upper 50s inland to mid 60s near the beaches.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. An extended period of quiet weather is expected through the middle of next week as a large area of high pressure remains centered across the Mid-Atlantic and Southeast regions. Dry conditions are expected for the next several days, but temps should gradually warm through the period under mostly sunny skies and a downslope wind component across the region early week, followed by mid-lvl ridging by the middle of the week. In general, highs will range in the mid/upper 80s each day, warmest across southeast Georgia away from the coast. Lows should initially range in the upper 50s inland to mid-upper 60s near the coast Sunday night, then gradually warm to the low-mid 60s inland to upper 60s/lower 70s as light sfc winds turn onshore midweek.

AVIATION /18Z THURSDAY THROUGH TUESDAY/. VFR will prevail through 18z Friday.

Extended Aviation Outlook: VFR conditions are expected at CHS/JZI/SAV terminals through Sunday.

MARINE. High pressure will build over the marine zones today through tonight. Surface winds are forecast to remain from the northwest today, averaging 10-15 knots. Winds will veer to the northeast tonight, speeds ranging between 10 to 15 kts. Seas this morning should range between 3 to 5 ft, highest beyond 20 nm.

Friday through Tuesday: High pressure will spread across region this weekend and prevail through early next week. The pattern will result in quiet weather conditions across local waters with winds/seas remaining well below small craft advisory levels. In general, north- northeast winds peaking around 15 kt Friday will weaken and turn more west-northwest Saturday into Sunday as sfc high pressure becomes centered just inland and north of the area. Light onshore winds should then develop as the center of the high begins to shift off the Mid-Atlantic Coast. Seas will average between 2-4 ft to start off the weekend, then gradually subside to 1-3 ft late weekend and persist through early next week.
