Area Forecast Discussion National Weather Service Charleston SC 335 AM EDT Sat Apr 19 2025
SYNOPSIS
High pressure will persist into early next week. A front will approach the region by the middle of next week then stall over or near the forecast area through late week.
NEAR TERM /UNTIL 6 AM THIS MORNING/
Sharp subtropical upper level ridge spans the southeast CONUS over top surface high pressure that extends well into the Atlantic. Synoptic pattern changes very little through tonight, with larger scale subsidence continuing to dominate across the southeast region. A somewhat deep mixed layer this afternoon might support some Cu development. Otherwise, our stretch of dry weather continues under sunny skies. Daytime highs will warm into the lower to middle 80s most areas, with some upper 80s possible well inland in Georgia. Cooler temperatures along the coast.
Tonight: Subtropical ridge and surface high pressure continue to dominate with dry weather continuing. Model RH forecasts and soundings do suggest sct-bkn high level cloud cover gradually edging into the region through the night, possibly leading to partly cloudy conditions. But quiet overall with lows in the middle to upper 50s inland, lower to middle 60s along the coastal corridor.
SHORT TERM /6 AM THIS MORNING THROUGH MONDAY/
Deep layered ridging will persist over the Southeast U.S. coast through the period. Strong subsidence will be prevalent as noted in model soundings via an 850mb capping inversion. Dry conditions are forecast with warming temperatures through the period. Some cirrus/high clouds will begin to move in Sunday night with a potentially thick layer aloft in place by Monday. This will limit the amount of heating; however, we still anticipate an overall daily temperature increase by a degree or so. Sunday will top out in the low to mid 80s. Monday, mid to upper 80s will be common everywhere except the beaches where it will stay in the mid to upper 70s. By Tuesday, some locations could peak around 90 degrees. Low temperatures will start off in the upper 50s/lower 60s Sunday night and warm into the low/mid 60s Monday night.
LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
A cold front will approach from the northwest Tuesday night, slowly sagging into the forecast area and then stalling across the forecast area Wednesday and Thursday. This will bring diurnally-driven showers and thunderstorms both days, enhanced by the afternoon sea breeze. The greatest POPs (30-40%) are focused across the southeast South Carolina interior, closer to where boundary interactions would occur. This location, however, will greatly depend on the location of the stalled front. By Friday, the front will retreat north, thereby decreasing rain chances. Temperatures will remain above normal through the rest of the week.
AVIATION /07Z SATURDAY THROUGH WEDNESDAY/
KCHS/KJZI/KSAV: VFR with the 06Z TAF cycle. No more than a little ground fog an hour or so around daybreak. Due to deep mixing heights and the sea breeze influences, southerly winds increase Saturday afternoon, peaking winds close to 20 kt at times.
Extended Aviation Outlook: Gusty winds are possible each afternoon at all terminals with the passage of the sea breeze. There are no other concerns.
MARINE
Southerly flow continues across the coastal waters through tonight, with afternoon sea breeze enhancement across Charleston Harbor and along the coast. Seas will run 2 to 3 feet today, increasing to near 4 feet in the Georgia outer waters.
Sunday through Thursday: High pressure will prevail in the Atlantic through the weekend and into early next week, yielding benign conditions and southerly flow. Expect higher winds near the coast and across the Charleston Harbor with the afternoon sea breeze. Seas should average 2-3 ft within 20 nm and 3-4 ft for the GA waters beyond 20 nm. No marine headlines are expected.
