Area Forecast Discussion National Weather Service Charleston SC 1201 AM EDT Fri Apr 26 2024

SYNOPSIS
High pressure will build into the region through early next week. A weak cold front could approach around the middle of next week.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/
Quiet conditions will linger tonight. A large area of clouds with bases of 1500-2000 ft over portions of coastal North Carolina into parts of the Pee Dee will drift southwest and penetrate into parts of the Charleston Tri-County into interior Southeast South Carolina through daybreak. This will result in a period of mostly cloudy skies. Elsewhere, mostly clear to partly cloudy skies will prevail. Lows from the mid-upper 50s inland to the mid-upper 60s at the beaches, warmest along the Georgia beaches, look on track.

SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/
Aloft, a large omega block will set up with amplifying troughs over the Western Atlantic and Western U.S. A ridge axis will settle over the Eastern Seaboard. This pattern favors quiet weather with little to no forcing. An isolated shower is possible mainly Friday along the southeast Georgia coast or far inland, where weak llvl convergence and presence of mid-level moisture co-exist. However, no mentionable POPs have been included in the forecast due to dry lower levels. Otherwise partly cloudy skies will prevail nearly each day.

High temperatures remain within a few degrees of normal, generally in the upper 70s to lower 80s each day through the weekend. Lows both Friday and Saturday night will range from the upper 50s inland to the mid 60s along the immediate coast.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
The pattern remains largely unchanged into early next week with the omega block and deep high pressure in place. This favors increasing temperatures and virtually zero rain chances Monday and Tuesday. The upper ridge axis will begin to shift offshore Tuesday as a weakening trough and accompanying weak cold front moves toward the eastern U.S. The front will be positioned inland late Tuesday/early Wednesday, however guidance depicts a weak or stalled boundary at that point. Showers will remain dependent on how quickly the upper trough driving the front lifts north. The forecast currently mentions slight chance POPs Wednesday afternoon which are limited to the inland locations.
Temperatures will start the period in the low 80s and will rise to the upper 80s/near 90F by the middle of the next week.

AVIATION /04Z FRIDAY THROUGH TUESDAY/
26/06z TAF Discussion: KCHS/KJZI: An area of MVFR cigs moving across coastal North Carolina and into the Pee Dee is on target to impact both the Charleston terminals by daybreak. While the bulk of these clouds look to move west of KCHS, their proximity to terminal necessitates the introduction of prevailing MVFR cigs, roughly 09-13z. For KJZI, the terminal will be on the southern periphery of these clouds, so a TEMPO group for MVFR cigs was highlighted for same time period. MVFR cigs should mix out to VFR by 14z and persist through 27/06z Saturday. Gusty winds with gusts 20-22 kt will impact both terminals as the sea breeze moves inland this afternoon.

KSAV: VFR through 267/06z Saturday. An area of MVFR cigs should remain north of the terminal this morning. Wind gusts near 20 kt will be common this afternoon as the sea breeze moves inland.

Extended Aviation Outlook: Prevailing VFR.

MARINE
Tonight: Surface high pressure will build across the eastern Great Lakes and down into the southeast. Easterly winds will slowly increase overnight in response, particularly across the South Carolina coastal waters. Speeds will average 10 kt from Edisto Beach and points south with 10-15 kt over the South Santee-Edisto Beach out 20 NM leg. Seas will average 2-4 ft.

Friday through Tuesday: Winds will shift NE Friday and then out of the east Saturday as high pressure builds from the north.
Brief surge will bring winds to the 15-20 kt range Friday afternoon/evening. Seas in turn will build to 3-5 ft across the nearshore waters out 20 nm and 5-6 feet across the outer Georgia waters from 20-60 nm. A Small Craft Advisory could be needed for the offshore Georgia waters overnight Friday into Saturday.
Winds around 10 kt or less will veer more southerly, and seas will decrease to 2- 4 ft Monday into Tuesday.

Rip Currents: Persistent onshore flow combined with moderate swell energy will enhance the rip current risk this weekend.
There is currently a Moderate risk of rip currents for all area beaches Saturday.
