SYNOPSIS
A stationary front will meander near or just off the coast through the end of the week. A weak cold front will drop into the forecast area early this weekend before high pressure spreads in from the north.

NEAR TERM /THROUGH TONIGHT/
Early this morning, IR satellite indicated that most of the Carolinas and Georgia was under a broken deck of mid and high clouds. These clouds should persist through the rest of this morning with the passage of broad H5 trough. The primary sfc feature is an area of developing low pressure over the Gulf Stream, off the coast of GA/SC. Near term guidance indicates that low will drift NNE today, gradually moving further off the coast. However, it appears that the forecast area will remain under the circulation associated with the system, producing gusty ENE winds over the beaches. By early this afternoon, a sea breeze should develop and move briskly inland through the rest of the afternoon, producing gusty winds inland. High resolution guidance indicates that sfc dewpoints in the wake of the sea breeze will surge into the low to mid 70s.
Temperatures should peak along and west of the sea breeze, ranging for the low to mid 90s across SE GA to the mid to upper 80s across the coastal counties.

As the sea breeze advances inland this afternoon, sfc conditions should feature temperatures in the mid to upper 80s with dewpoints peaking in the mid 70s in some locations. SBCAPE values are forecast to exceed 1500 J/kg, primarily along and east of the I-95 corridor.
Recent runs of the HRRR and HRRR indicate that isolated to scattered thunderstorms will develop in this environment. Shear should remain weak, convective activity should be limited to pulse-like thunderstorms.

Tonight, the sfc low over the western Atlantic is expected to accelerate to the NE. As the low departs, dry high pressure will be drawn east across the forecast area. PoPs will end over land this evening, then decreasing across the marine zones through tonight.
Low temperatures are forecast to range from the upper 60s across the inland counties and low 70s along the coast.

SHORT TERM /FRIDAY THROUGH SUNDAY/
Friday: An upper trough, largely limited to the Mid-Atlantic, will push a cold front toward the area from the northwest Friday/Friday night. Drier high pressure inland will keep showers and thunderstorms largely limited to the coastal waters in proximity to a weak surface low. Mostly sunny skies are forecast with dew points mixing out into the low to mid 60s away from the coast. Highs will reach the low/mid 90s with lows in the lower/middle 70s.

Saturday: As the weakening cold front pushes across the area Saturday, the coastal low will quickly push out into the Atlantic. Weak flow aloft will become replaced by a building ridge from the southwest. As a result, Saturday features rain- free conditions with mostly clear skies as subsidence over the area strengthens. A rogue shower or storm could occur with the FROPA, but for now we have POPs 15% or less across the area. An increase in temperatures will occur due to compressional heating. Highs will likely reach the upper 90s most places, while some places could top out at 100 degrees. The beaches will remain a bit "cooler", peaking near 90 degrees. Strong subsidence will allow surface dew points to mix out into the low/mid 60s for areas away from the coast heading into peak diurnal heating. Therefore, heat indices should stay shy of Heat Advisory criteria; ranging between 100-104 degrees.

Sunday: A deep layered ridge will center nearly overhead as surface high pressure sets up across the Northeast. Return flow helping to wrap the deeper Gulf moisture around the backside of the high could provide enough moisture/instability to support isolated to scattered showers and thunderstorms, mainly during the afternoon and evening hours when the sea breeze is active. However, a strong subsidence cap around H6 should limit deep convection/thunderstorm chances. Highs are expected to reach the low to mid 90s away from the immediate coast.

LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/
Anticyclonic flow aloft, mainly across the Southeastern U.S., will prevail through early next week. Surface high pressure located along the New England coast will advect modestly dry air into the area despite the onshore flow, although some Atlantic moisture could move in far south into Southeast Georgia. The forecast features isolated showers in the afternoon/evening each day through early next week. Thunderstorms chances look slim at this juncture with little instability to work with and little to no forcing with a fairly strong capping inversion in place.
Convection chances could increase if additional moisture advection occurs, which for this time of year, is pretty easy to have happen. Temperatures should sit around normal or slightly above normal due to increased insolation.

AVIATION /08Z THURSDAY THROUGH MONDAY/
6Z TAFs: An area of low pressure will develop well off the GA and SC coast through the TAF period. Circulation around the low will provide the terminals with steady NE winds through this morning. A sea breeze is forecast to develop early this afternoon and advance quickly inland across KCHS/KJZI/KSAV by 17Z, yielding ENE winds gusting near 20 kts. Instability will increase across the coastal counties in the wake of the sea breeze. Isolated showers and thunderstorms may develop near the terminals this afternoon. Each TAF will feature a mention of VCSH. Winds will settle to 5 to 10 kts by 0Z.

Extended Aviation Outlook: Mostly VFR conditions expected through Saturday. Flight restriction chances return Sunday with greater coverage of showers/thunderstorms, followed by brief flight restriction possibilities early next week within afternoon showers/thunderstorms.

MARINE
Today, the coastal waters of SE GA/SC will be positioned between a developing area of low pressure over the Gulf Stream and weak ridge across the Carolinas. This pattern should result in a tightening pressure gradient today, especially after the sea breeze develops early this afternoon. ENE winds are forecast to range from 10-15 kts with gusts exceeding 20 kts. Some locations across the coastal waters may approach Small Craft Advisory criteria winds this afternoon. Seas should build through the day, reaching 3-5 ft this afternoon.

Tonight, the low should accelerate to the northeast, gradually relaxing the pressure gradient across the nearshore waters. By late tonight, winds are expected to favor a northeast direction, speeds decreasing to 10 to 15 kts. Seas should decrease to 2-4 ft late tonight.

Rip Currents: Gusty east-northeast winds will remain along the beaches today. The winds should result in a moderate to strong longshore current. In addition, breaker heights may exceed 2 ft, especially along the SC coast, at 7 second periods. There is some potential that wind gusts could approach 25 mph, especially if the area of low pressure over the Gulf Stream deepens faster than anticipated. Given the combination of stronger longshore current, gusty winds, and larger breakers, and recent rip current activity; the rip risk will be moderate today.

Friday through Tuesday: A weak area of low pressure will reside off the Carolina coast Friday. Broad high pressure inland will result in winds initially out of the north/northeast. But with the low quickly departing into the Atlantic Friday night, winds will briefly veer out of the southwest Saturday with speeds dropping to 5-10 kt.
Easterly winds will return Sunday as high pressure builds in from the north. Wind speeds will average 10-15 kt with seas 2 to 4 feet through early next week.
