SYNOPSIS
High pressure will extend across the region today. A tropical wave will impact the Southeast U.S coast tonight into Friday.
High pressure will return over the weekend.

NEAR TERM /THROUGH TONIGHT/
High pressure will continue to maintain control over the area today.
Meanwhile, a tropical wave northeast of the Bahamas will track west-northwestward towards the Southeast coast. Still seeing a few showers moving onshore on latest radar imagery, but they have been very light and short-lived. The 12z KCHS RAOB showed mid level dry air and a notable subsidence inversion around 800 mb. This environment will act to limit the chance of measurable rainfall. Otherwise, the ridge of high pressure inland and the approaching wave will drive gusty east- northeast winds, especially along the coast where gusts up to 25-30 mph will be possible. High temperatures will peak in the upper 80s to around 90.

Tonight: The ridging aloft continues to hold firm, and steers the tropical wave to a position offshore the Florida northeast coast between Cape Canaveral and Jacksonville. Moisture continues to increase, with PWat reaching 1.5 to 2 inches over eastern sections late. Low level convergence also intensifies with a 25-35 kt just offshore, and there is a slight decrease in heights aloft. This will allow for an increasing chance of convection through the night as the tropical wave draws a little closer. By morning we show scattered showers over the coastal corridor, with slight chance PoPs further inland. There is even MLCAPE in excess of 1000 J/kg near the coast, so we do have slight chance of t-storms. At this point the QPF for tonight is mainly 1/4 inch or less. So no flooding concerns.

Winds remain elevated along and close to the coast, but they do diminish inland from what they were during the daylight hours.
There's still enough dry air holding on far inland to allow for lows in the upper 60s. But with the increase in moisture further east, lows will only drop to the lower and middle 70s.

SHORT TERM /FRIDAY THROUGH SUNDAY/
Aloft, an anticyclone will be positioned over the Mid-Atlantic to start Friday. While at the surface Friday morning will begin with an inverted trough impacting the southeast coastline. This trough will bring a plume of tropical moisture into the region, with PWATs hovering around 2 inches through the daytime. Scattered to numerous showers and thunderstorms will be possible, with the greatest chances across southeast Georgia. Overall, rainfall amounts look to amount to 0.25-0.5 inches across the forecast area, so there are no rainfall/flooding concerns at this juncture. Highs will be right around normal, reaching into the low 90s inland with upper 80s elsewhere. Overnight lows will dip into the low 70s inland with mid to upper 70s along the coastal counties.

Broad mid-level ridging will develop on Saturday and persist into Sunday, while at the surface the aforementioned inverted trough will likely linger in the vicinity of the Florida/Georgia border. With the lingering trough will also be lingering moisture, with PWATs remaining near 1.8 inches through the weekend. Showers and thunderstorms will be possible each afternoon, especially across southeast GA where the moisture will be greatest. Temperatures will gradually warm through the weekend, with highs in the low to mid 90s on Saturday and mid to upper 90s on Sunday. Overnight temperatures will be in the mid to upper 70s.

LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/
A broad trough will progress from the Great Lakes into New England early in the week. At the surface a cold front will approach the region, however it will likely be in a weakening state and will most likely not make a clear passage through the region. Through the rest of the period conditions will return to a summertime pattern of afternoon showers and thunderstorms. Temperatures on Monday are forecast to reach into the mid to upper 90s, with little mixing out of dew points. Heat index values are forecast to reach around 105F across most areas, with some locations seeing values around 108F.
Heat Advisories may be required. It is worth noting that potential convection could disrupt the temperatures.

AVIATION /18Z THURSDAY THROUGH TUESDAY/
VFR will prevail through at least the first half of the night.
A tropical wave is expected to approach the Southeast coast tonight and move onshore near the Georgia/Florida border on Friday. This will bring a potential for a period of MVFR ceilings and showers in the morning. Otherwise, gusty east winds this afternoon will subside after sunset.

Extended Aviation Outlook: Flight restrictions will be possible at all terminals Friday through the weekend with showers and thunderstorms moving onshore.

MARINE
Today and tonight: A strong high pressure ridge will remain anchored to the north of the local waters, steering a tropical wave from northeast of the Bahamas this morning to offshore the northeast Florida coast by daybreak Friday. The gradient between these two features will produce solid Small Craft Advisories over the Atlantic, and also a Small Craft Advisory in Charleston Harbor. ENE winds will be as high as average 20-25 kt with some higher gusts in the Atlantic, and winds will eventually reach similar speeds in Charleston Harbor into early this evening. The favorable fetch will allow for seas as high as 6 and 7 feet within 20 nm, and 8 or 9 feet on the outer Georgia waters. Waves in Charleston Harbor will be up to 2 feet.
Marines can expect isolated t-storms moving tonight in response to the tropical wave.

Friday through Monday: An inverted trough will impact the marine zones Friday, likely lingering into the weekend. Thereafter high pressure will build into the region. Winds Friday will be out of the ENE, around 10 to 15 knots. Winds will shift to the SE around 10 knots by Saturday night. Seas are forecast to average 5 to 6 ft until Friday afternoon across the nearshore waters. Small Craft Advisories are in effect until Friday afternoon. Across the 20-60 nm offshore GA waters seas will take a little longer to subside, with 5 to 6 ft persisting into early Friday night. All Small Craft Advisory conditions should be clear of the forecast area to start Saturday, with conditions remaining below criteria through the remainder of the period.

Rip Currents: Conditions at the beaches today is very similar to the past few days, where we have had several dozen rip currents (many of them strong) at Tybee Island. So we expect additional frequent and strong rip currents again today at all beaches, with the greatest coverage at Tybee.

A High Risk for rip currents has been maintained for Friday across all area beaches. An enhanced risk of rip currents could persist into Saturday as long period swell impacts the region.

High Surf: While there can be some occasional 5 foot breakers in the surf zone today, most breakers will be 3 or 4 feet, so no High Surf Advisory is required. Even so, some coastal areas will experience erosion.

TIDES/COASTAL FLOODING
Tides continue running near or even greater than a foot above astronomical levels, and with a continued moderate to strong east and northeast wind, and the Full Moon to occur Friday evening, those departures could grow even more. With a slightly higher astronomical tide, it is possible minor coastal flooding could occur over the coastal sections of Charleston and Colleton Counties with the high tide this evening. Tides elsewhere are forecast to remain below minor flood stage.
