Area Forecast Discussion National Weather Service Charleston SC 741 PM EDT Mon Jun 1 2020

SYNOPSIS. High pressure will prevail with dry weather through Wednesday before more unsettled weather returns into early next week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Early this evening: No change to the forecast through the overnight. Previous discussion continues below.

The region will remain pinned between a large subtropical ridge centered over the southern Mississippi Valley and a sharp upper trough offshore off New England. At the surface, modified Canadian high pressure will hold its influence on the region tonight as it slowly propagates to a position southeast of the North Carolina Outer Banks by daybreak Tuesday. Diurnal cumulus will quickly dissipate after sunset with the loss of insolation, but some thin cirrus could traverse portions of mainly Southeast Georgia overnight. The boundary layer should decouple across the interior later this evening while east/southeast winds of 5-10 mph should persist across the coastal counties. This will result in a large temperature gradient with lows ranging from the upper 50s/lower 60s inland to the mid-upper 60s at the coast with lower 70s at the beaches and Downtown Charleston.

SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/. Moderate to high confidence this period. Atlantic high pressure will remain centered east of the area while the region stays positioned between an upper trough to the northeast and upper ridge to the southwest on Tuesday into Wednesday, then the upper trough will take over into Thursday. We do not expect any rainfall until possibly Wednesday night, mainly across southeast GA, as deeper tropical moisture starts to shift northward into the area. On Thursday, most locales will see some rain chances, however the most rain is likely close to the Savannah River and points south where the deeper moisture is likely to be. There does not appear to be any appreciable severe weather and/or flooding threat at this time. Temperatures should be near to below normal through the period.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. The pattern will become a bit more unsettled late week into the weekend. Models hint at a weak wave of low pressure and a slug of moisture lifting up the coast Thursday night into Friday. A cold front will then slowly approach from the northwest on Saturday, before pushing into the area on Sunday. Plenty of moisture and convergence along the front/trough axis will maintain mention of showers and thunderstorms. Rain chances will peak during the day when instability is maximized. Temperatures will be near or slightly above normal.

AVIATION /00Z TUESDAY THROUGH SATURDAY/. VFR conditions will prevail at KCHS and KSAV through 00z Wednesday.

Extended Aviation Outlook: Periodic restrictions from low clouds, showers and possible thunderstorms at KCHS/KSAV starting Thursday.

MARINE. Tonight: Seas look to remain 6 ft or higher across the Georgia offshore waters through tonight, so flags will remain in force for that area through sunrise Tuesday. Otherwise, east to southeast winds will settle into the 10-15 kt range overnight, possibly a bit lighter across the South Carolina waters which will be closer to the center of the surface high after midnight.

Tuesday through Saturday: Moderate to high confidence through the period. The area will remain on the western periphery of Atlantic high pressure with southerly winds prevailing. Conditions will stay below Small Craft Advisory levels for the most part, although can't completely rule out marginal SCA conditions, especially in Charleston Harbor Tuesday and Wednesday afternoon.

Rip Currents: Depending on how much swell energy remains over the Atlantic waters Tuesday there could still be an elevated risk for rip currents, especially along the SC coast.

TIDES/COASTAL FLOODING. The upcoming lunar perigee, full moon, persistent onshore winds and some lingering swells will result in elevated tide cycles this week and into the weekend. Minor coastal flooding will be possible during the evening high tides, mainly along the South Carolina coast. There is even a low risk for moderate coastal flooding along the SC coast starting mid week.

CHS WATCHES/WARNINGS/ADVISORIES. GA . None. SC . None. MARINE . Small Craft Advisory until 8 AM EDT Tuesday for AMZ374.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
