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/
Today: A large mid and upper anticyclone ans its associated ridge will be situated from off the Delmarva in the Atlantic into the central states. Meanwhile, a surface and low level ridge is generally in the same locations, while to the south a tropical wave to the northeast of the Bahamas will move west- northwest. By evening that feature will be north of the Bahamas and well east of Cape Canaveral, with central pressures down to just near 1015 millibars. NHC has designated this system as AL92, and is showing just a 30% chance of any tropical cyclone formation.

The large scale subsidence associated with the ridging both surface and aloft, poor thermodynamics, and considerable dry air above a capping inversion around 800-850 millibars will only allow for isolated to scattered low-topped showers. The best chances are this morning, when the strongest frictional convergence occurs over the coastal counties. This will also be yet another day without any t-storms, which is certainly a rare occurrence for the first day of summer, with the solstice to begin at 451 PM EDT.

Just like the past few days, it'll be breezy to windy across the entire area with a fairly tight gradient between the tropical wave to the southeast and the ridge to the north. Expect easterly winds as high as 15-20 mph with gusts of 25 or 30 mph over the coastal counties, and up to 15 mph with gusts of 20 mph or a little higher far inland.

The deep onshore flow will hold temperatures near or just below climo, with the vast majority of the region held down in the 80s.

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 /12Z THURSDAY THROUGH MONDAY/
KCHS/KJZI/KSAV: Moisture convergence from off the Atlantic will produce isolated showers at or near the terminals this morning.
We have VCSH as a result. Otherwise, a better chance of rain will exist late tonight in response to a tropical wave to the south of the area. For now we have VFR ceilings, but flight restrictions are possible late tonight.

All sites will experience gusty easterly winds yet again late this morning into the evening, frequently achieving 20-25 kt, and occasionally stronger.

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 eventually 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 from late morning 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.
