Area Forecast Discussion National Weather Service Charleston SC 748 PM EDT Fri May 29 2020

SYNOPSIS. A cold front will slowly approach the region from the west tonight and Saturday, moving offshore late Saturday night. High pressure will then build into the area and prevail through the middle of next week.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. This evening: the seabreeze has pushed generally west of I-95 over our SC zone, which is also where isolated to scattered showers and thunderstorms are located. However, further south, a large cluster of showers and isolated thunderstorms has moved northward into our southern GA area. Expect scattered to numerous showers and isolated thunderstorms to continue over our GA zones through the next hour or so, while scattered showers and thunderstorms continue to push slowly westward with the seabreeze over SC zones.

Tonight: Expect most convection will diminish after 10 pm this evening. However, later tonight, models indicate isolated showers to re-develop. Confidence with this is not very high, so have kept slight chance to chance PoPs most areas through the night. Feel the better chance for late night showers and isolated thunderstorms may be over coastal areas from roughly Beaufort northward to Charleston. This is where southerly low level flow may advect marine based showers over coastal regions between 4 am and sunrise. Temperatures will remain mild, generally in the upper 60s to lower 70s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/. Saturday and Saturday night: Aloft, the forecast area will sit within the broad trough and cyclonic flow around a large upper low well to the north. At the surface, a cold front will start the day stretching from the Florida panhandle across central Georgia and the western Carolinas. The front will slowly make eastward progress through the day, and is progged to push off the coast by sunrise Sunday. Ahead of the front during the day, we will remain in the warm moist southerly flow. We should see plenty of destabilization and one more day of numerous to widespread coverage of showers and thunderstorms. One notable difference from Friday will be drier air in the mid-levels, evident in model soundings. This will allow for DCAPE values to rise to around 1,000 J/kg in the afternoon and will yield a modestly higher severe weather threat, primarily for damaging wind gusts. Overall, there isn't much to help organize thunderstorms and development and evolution will largely be determined by boundary interactions. Prior to the start of convection, temperatures should be able to warm into the mid and upper 80s. Overnight as the front reaches the coast and then moves offshore, at least scattered showers and thunderstorms will continue. The forecast features rain chances varying in the 30-50 percent range, diminishing by sunrise Sunday as the front makes it offshore.

Sunday through Monday: Overall, much quieter conditions will arrive with lessening coverage of diurnal convection. Despite the front being offshore Sunday, high pressure will build in and help push a trailing surface trough southward along the coast. There should be enough low-level convergence to kick off isolated to scattered convection in the afternoon and we have maintained 20-30 percent rain chances. This activity should be focused along the coast. As the high more completely builds in Monday, a notable airmass change will take place. In addition to there being no convection expected, temperatures are expected to cool off nicely. Highs are forecast to range mainly in the low 80s which would be around 5 degrees below normal for early June.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/. High pressure will shift into the Atlantic on Tuesday and then remain the dominant feature into Thursday, although troughing will develop inland. Aloft, ridging will encompass much of the southern half of the country. Models are in good agreement showing a quiet period with minimal rain chances. Temperatures will gradually warm as return flow sets up and heights build aloft.

AVIATION /23Z FRIDAY THROUGH WEDNESDAY/. Tonight: Have not made any major changes to the previous TAFs for both CHS and SAV. Large area of light showers expected to spread over SAV, but flight restrictions are not anticipated. Expect generally VFR this evening, but then guidance indicated MVFR to IFR CIGS later tonight. Have kept MVFR for now due to uncertainty. Showers may redevelop later tonight, especially CHS with MVFR conditions possible.

Saturday: Models indicate that convection will again form as a surface trough moves toward the area in the afternoon. Have indicated VCTS for now at CHS, but left out of SAV due to higher uncertainty for timing and coverage at that location.

Extended Aviation Outlook: Thunderstorms could impact KCHS and KSAV Saturday afternoon and evening. Otherwise, VFR.

MARINE. Tonight: The coastal waters will be situated between high pressure in the Atlantic and troughing over land. No highlights are expected. Outside of scattered convection, sustained winds will average 10-15 kt. Seas will average 3-4 ft.

Saturday through Wednesday: Ahead of a cold front, conditions will remain below Small Craft Advisory thresholds through Saturday night. The front will move off the coast late Saturday night and high pressure will build in from the north into Monday. As the high builds in, winds will steadily strengthen and become northeasterly on Sunday. Winds and seas will both increase Sunday into Monday and Small Craft Advisories will likely be needed for at least portions of the local waters. Conditions will improve Monday evening and remain below advisory thresholds into the middle of next week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
