Area Forecast Discussion National Weather Service Charleston SC 334 PM EDT Wed Apr 24 2024

SYNOPSIS
A weak trough will drop into the region tonight into Thursday.
High pressure builds back into the region late week through the early part of next week.

NEAR TERM /THROUGH TONIGHT/
Upper level trough and associated surface low is swinging through New England this afternoon with a trailing boundary/ surface trough arcing down into the mid-Atlantic and Appalachia and further into northern Georgia. Modest moisture ribbon is stretched out ahead of the trough with PWAT values around one inch and a band of cloud cover with bases mainly above 5K feet.
There is some light precip moving through parts of North Carolina and spotty radar returns in northern Georgia. But otherwise, relatively benign conditions exist across the region.

Tonight: Surface trough/wind shift line will be sliding down through the region late this evening through early Thursday morning. As noted in previous discussions, model guidance and forecast soundings remain very unimpressive from a precip potential standpoint, showing a layer of cloud cover (2-3K feet thick) passing through the region superimposed along a corridor of weak lower level QG-forcing for ascent, but fairly dry layers above and below. Thus, it's difficult to imagine that we will get much in the way of measurable precip. That said, high- resolution guidance sources continue to show spotty showers/ sprinkles along the trough dipping into the northern part of the forecast area before dissipating. So, we have opted to retain low end (isolated) precip chances largely in the 03Z to 09Z timeframe and for just across the far northern part of the forecast area.

Lows Thursday morning will range from the mid-upper 50s inland to the lower-mid 60s at the beaches and Downtown Charleston.

SHORT TERM /THURSDAY THROUGH SATURDAY/
A weak front/trough will push offshore as a wedge of high pressure builds south Thursday. Aloft, a large omega block will begin to set up with amplifying troughs over the Western Atlantic and Western U.S. A ridge axis over the Central U.S will gradually shift toward the Eastern Seaboard, and settle in place through at least the first half of the weekend. Overall, quiet weather is expected with little to no forcing; however models generate a few light showers at times with onshore flow. Slight chance PoPs are in place for Friday afternoon across inland southeast Georgia where there has been some persistence, but otherwise the chance for measurable rainfall was low enough to preclude mention in the forecast.

High temperatures remain within a few degrees of normal, generally in the upper 70s to lower 80s each day. Lows both nights range from the mid/upper 50s inland to the mid 60s along the immediate coast.

LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/
The pattern remains largely unchanged through the early week with the omega block and deep high pressure in place. This favors increasing temperatures and virtually zero rain chances. The upper ridge axis will finally begin to shift offshore Tuesday as a weakening trough and accompanying weak cold front moves into the eastern U.S. It should be another dry day across much of the area, however a few showers could impact inland areas during the latter half of the day. Temperatures will start the period in the upper 70s/low 80s and will rise to the upper 80s/near 90F by the middle of the next week.

AVIATION /18Z WEDNESDAY THROUGH MONDAY/
24/18z TAF Discussion: KCHS/KJZI/KSAV: Solid VFR conditions will prevail through the period.

There is a touch of smoke across the region that will cycle through today along with a few afternoon clouds. Weak southward moving surface trough will bring a band of thicker VFR cloud cover down into the region tonight. Some very spotty showers or sprinkles are possible along the trough, mainly across parts of southeast South Carolina. We continue to carry VCSH for both KCHS and KJZI later this evening to highlight this. No impacts are expected.

Winds veer into the north behind the trough for Thursday.

Extended Aviation Outlook: Prevailing VFR.

MARINE
Southwest winds will diminish to near 10 kt overnight as a surface trough slips south into the local marine areas. A few showers could impact mainly the South Santee-Edisto Beach nearshore leg and Charleston Harbor during the overnight hours, although the overall precip potential is very low. Seas will average 2-3 ft in the nearshore waters out to 20 NM and the 3-4 ft over the Georgia offshore leg out 20-60 NM.

Thursday through Monday: Winds will shift ENE Thursday and then persist through late week 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 2-4 ft across the nearshore waters out to 20 nm and 5-6 feet across the outer Georgia waters. A Small Craft Advisory could be needed for that particular marine zone for a brief period overnight Friday. Winds veer more southerly early next week with no additional marine concerns.

Rip Currents: Lingering swell, onshore winds and lunar influences will continue to support a moderate risk for rip currents for all beaches through early evening.

EQUIPMENT
The KCLX radar is undergoing electrical maintenance and is tentatively scheduled to return to service April 26th.
