Area Forecast Discussion National Weather Service Charleston SC 833 PM EDT Wed Jul 5 2017 .SYNOPSIS... Atlantic high pressure will prevail through late week. A weak cold front will then approach the area this weekend. Atlantic high pressure will return early next week. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... Another update has been issued to increase PoP coverage into the high end chance/likely range based on clusters of merging storms over parts of interior GA. Plenty of lightning and possible severe on the storm in Liberty County. We also adjusted the diurnal curve to account for diabatic cooling where scattered-likely coverage occurs prior to midnight. The combination of the sea breeze and various meso-scale boundaries interacting with one another this evening will result in scattered convection across parts of interior GA through mid to late evening. We raised the coverage of showers/t-storms to as high as 30-40%, and also extended the ending time by about 2 hours. DCAPE as high as 1300-1400 J/kg and MLCAPE pushing 2000 J/kg supports a risk of strong or marginally severe winds in one or two storms. Based on some of the DVIL and LRM cores on storms there is also a risk of moderate to large hail. During the late evening and early post-midnight hours look to be quiet with little to no risk of convection, before a slight chance of showers/t-storms develops near or just off the Charleston County coast due to low level moisture convergence. The warm synoptic flow and the hot temps to start the night will hold temps above 80F through 04-05Z for most communities, with some coastal sites not even dropping below 80F the entire night. We'll be close to record high minimums for July 5th and 6th for all three climate sites. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... Thursday and Friday: Atlantic high pressure will extend across the region through late week, providing a summertime type pattern over much of the area Thursday. By Friday, high pressure will gradually retreat over the western Atlantic while a piedmont trough is slightly enhanced by an area of low pressure shifting over the Mid- Atlantic states. The overall trend will favor warm conditions and increasing chances of showers/thunderstorms, particularly over inland areas of Southeast South Carolina Friday afternoon/evening. Temps should peak in the mid/upper 90s on Thursday, then mid 90s on Friday with a slight increase in clouds and convective coverage. Overnight lows will be mild, ranging in the mid/upper 70s. Saturday: A weak cold front will attempt to push into the region late, but could stall and/or dissipate near the area this weekend. Given a slight uptick in forcing along with PWATs between 1.5 to 1.75 inches and SBCAPE around 2500 J/kg over Southeast Georgia and coastal areas, a slight chance to chance of showers/thunderstorms will be possible. Greatest chances appear to be in Southeast Georgia along the coast. High temps will be warm, peaking in the low/mid 90s. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... Bermuda high pressure will remain in place through the middle of next week. Weak upper troughing to our west may support greater coverage of showers and tstms. Temperatures will be near normal. && .AVIATION /01Z THURSDAY THROUGH MONDAY/... Scattered SHRA/TSRA near the KSAV terminal could still become a problem with sub-VFR conditions and potential impacts. We will continue to carefully monitor. The next chance of convection occurs Thursday afternoon/evening near both KSAV and KCHS. But probabilities are low enough where no mention of SHRA/TSRA is required at this time. Thus VFR will prevail. Extended Aviation Outlook: Brief flight restrictions are possible during showers/thunderstorms at both KSAV and KCHS, mainly in the afternoon and evening hours this weekend. && .MARINE... Tonight: The axis of an elongated surface high will remain south of the coastal waters. The pressure pattern will yield S-SW winds as high as 13-018 kt throughout the night, veering slowly with time. Seas will hold around 2-3 ft. Thursday through Monday: Winds/seas are expected to remain below Small Craft Advisory levels through the period while Atlantic high pressure dominates the coastal waters. However, a slight pinching of the gradient could support wind gusts as high as 20-25 kts over northern SC waters Friday night. A weak front could approach the waters late weekend, but Atlantic high pressure will likely prevail early next week. In general, south/southwest winds will peak near 15- 20 kts over most waters. Seas will range between 1-3 ft through Thursday, then slowly build to 2-4 ft this weekend. Seas should slowly subside to 1-3 ft early next week. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None.
