SYNOPSIS. High pressure will remain the dominant feature through next weekend.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. For information concerning the 3 earthquakes that impacted the Charleston Tri-County area today, including the magnitude 3.3 that struck around 621 PM EDT, refer to earthquake.usgs.gov.

The forecast is on track and did not require any major updates.

Sprawling high pressure centered offshore the Carolinas will hold its influence tonight. KCLX reflectivity data and surface observations show the sea breeze is a bit stronger and more defined than yesterday, so it will likely take a bit longer to decay after sunset compared to previous evenings. Still, the boundary layer should decouple later this evening with winds going calm across the interior with light southwest winds holding across the coastal counties inland from the Intracoastal Waterway. What is left of the diurnal cumulus field will quickly dissipate after sunset. Some high clouds will pass through overnight, but these look to remain very thin. Radiational cooling should prevail once again although possibly not as strong as the past few nights. Early fall-like temperatures will persist with lows dropping into the lower 60s inland to around 70 at the beaches and Downtown Charleston. A few upper 50s are likely in some of the normally cooler, more sheltered inland locations.

SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/. Tuesday through Thursday: High pressure will prevail Tuesday, then weaken and get replaced by a inland surface trough Wednesday. By Thursday, a backdoor cold front will likely approach and hang up just to the north of the forecast area. Plentiful dry air will prevail through the period, and the forecast remains dry. The most notable forecast issue will be temperatures. Highs will gradually warm each day, peaking in the upper 80s to low 90s by Thursday. Such values would be on the order of 5 degrees above normal for late September.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. There continues to be some model disagreement regarding the backdoor cold front and its southward progress Thursday night and Friday. The ECMWF (27/12z) still allows the front to completely clear the area by Friday afternoon while the GFS (27/12z) keeps it just north of the area. The forecast follows WPC and NBM guidance which is more like the ECMWF and brings the front through. With that in mind, there continues to be some risk of isolated showers and thunderstorms Friday afternoon and the forecast depicts 20 percent chances for most of coastal southeast South Carolina. Also, a modest cool down is anticipated behind the front with temperatures returning to near-normal values for the weekend and into early next week. Overall, a very quiet weather pattern continues.

AVIATION /01Z TUESDAY THROUGH SATURDAY/. VFR conditions will continue through 00z Wednesday.

Extended Aviation Outlook: VFR conditions will prevail.

MARINE. Tonight: South to southeast will will veer southwest overnight with speeds 10 kt or less. Seas will average 1-2 ft nearshore waters with 2-3 ft offshore waters.

Tuesday through Saturday: Quiet conditions will prevail across the local waters through Thursday with modest south to southwest surging expected each afternoon and evening. Wind speeds should generally top out in the 10-15 knot range. A backdoor cold front should then pass through from the north Friday and usher in a period of northeast flow into the weekend. For now, the forecast only features winds up to around 15 knots, but depending on the gradient speeds could be higher. For seas, swell energy from distant Hurricane Sam is expected to arrive beginning Friday and seas will steadily increase into the first half of the weekend. Small Craft Advisory seas will be possible in at least portions of the waters during this time.
