Area Forecast Discussion National Weather Service Charleston SC 1138 AM EDT Thu Jul 2 2020

SYNOPSIS. A stationary front will linger over or near the area into this weekend. A low pressure system could then impact the area early next week with drier weather to likely follow through Wednesday.

NEAR TERM /THROUGH TONIGHT/. Today: A small cluster of showers continues near the South Carolina and Georgia state line where h5 shortwave is advancing east- southeast and eventually shifting offshore. For the next few hours showers will continue in this area before shifting off the coast. As we enter the afternoon, the mid/upper levels will feature a trough of low pressure extending south along the Eastern Seaboard and strong ridging associated with high pressure across much of the Central United States. At the sfc, a weak/stationary front will remain draped across the area for the day. Subtle waves of energy will form along the front, which in combination with an afternoon seabreeze should provide the main focus of afternoon/evening convection. At this time, the severe weather threat will remain low across the area, but a few stronger thunderstorms and/or isolated severe thunderstorm can not be ruled out given MLCAPE approaching 1500-2000 J/kg as sfc temps peak in the upper 80s to lower 90s this afternoon and DCAPE approaching 1000-1200 J/kg as drier air begins to shift into the region aloft from the northwest. Should a strong and/or severe thunderstorm develop this afternoon into the evening, the main concern will be damaging wind gusts.

Tonight: A more pronounced surface low forms well offshore in response to short wave energy aloft, as high pressure noses in from the upper Midwest and upper Mississippi Valley regions. Isolated to scattered convection in the evening will fade quickly, ending no later than about 10 to 11 pm. Decreasing cloud cover, light or calm winds and wet grounds will promote the formation of patchy fog. The best chances of such occurring would be along our northwest tier of the South Carolina counties where the most favorable condensation pressure deficits will be found. There could actually be a few upper 60s in the Francis Marion National Forest, otherwise lower and middle 70s will be more common.

SHORT TERM /FRIDAY THROUGH SUNDAY/. Moderate confidence this period. Latest medium range guidance is in a bit better agreement compared to 24 hr ago. A weak low pressure system is likely to be well east of the area into the Atlantic Friday before pulling farther away while another weak low pressure system possibly develops inland Saturday night or Sunday. The deepest moisture will be south of the forecast area until possibly Sunday so rain chances look minimal until then, and even on Sunday should mainly be in GA. No significant severe/flash flood potential is expected through the period.

Temperatures should be above normal until possibly Sunday when they could drop below normal.

LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/. Low to moderate confidence this period with much depending on the evolution of weak low pressure over or near the area early in the period, mainly Monday and Tuesday. At this point we think the chance of severe weather/flash flooding will be low. The best risk for flash flooding is likely to be in coastal flood-prone areas like Downtown Charleston around times of high tide. High temperatures should be near to below normal, likely coolest on Monday, while low temperatures likely stay above normal.

AVIATION /15Z THURSDAY THROUGH MONDAY/. VFR will prevail at both KCHS and KSAV through 12Z Friday. However, since scattered SHRA/TSRA will form during the mid and late afternoon hours today, we have mention of VCTS from 19Z through to about 23-24Z. Should a direct impact from this convection occur, gusty winds and flight restrictions could briefly occur. There could be a little fog late tonight, especially if rain occurs prior to then. But not enough to justify including in the forecast at this time.

Extended Aviation Outlook: Moderate to high confidence in mostly VFR conditions at KCHS/KSAV through Tuesday. Periodic restrictions expected, mainly from afternoon/evening showers and thunderstorms starting Sunday.

MARINE. Today and Tonight: A broad area of low pressure will begin to shift off the Southeast coast near a stationary front today, favoring west winds at or below 10 kts becoming more south during the day. Further offshore, wind speeds should temporarily gust between 15-20 kt, before slowly weakening through the afternoon. Seas will generally range between 1-2 across nearshore waters and 2-3 across offshore Georgia waters. Overnight, an area of low pressure will form along the front to the east of the local waters as it heads further offshore with time. Outside of any isolated to scattered convection, there are no concerns regarding winds and seas.

Friday through Tuesday: Moderate to high confidence through Friday with low to moderate confidence thereafter as a low pressure system could move over or near the waters. At this time we are forecasting winds mostly 15 kt or less and seas mostly 3 ft or less, although much depends on the strength/track of the potential low pressure system.

TIDES/COASTAL FLOODING. Positive tidal departures will continue again today, leading to the risk for shallow salt water flooding with the 630-700 pm high tide over parts of the South Carolina coast, mainly in and near downtown Charleston. A Coastal Flood Advisory will likely be required at a later time.

Astronomical influences will make tides higher than normal into early next week and a potential low pressure system early next week could cause even higher tides. At this time we think the best chance of mainly minor coastal flooding will be along the South Carolina coast around the times of the evening high tides. Coastal Flood Advisories could be required. Furthermore, the risk for heavy rain will only add to any tidal flooding.
