SYNOPSIS
High pressure will prevail across the region through tomorrow.
A cold front will approach the region Friday, stalling in the vicinity through the weekend. Another cold front will push through the region early next week, with high pressure returning by the middle of the week.

NEAR TERM /UNTIL 6 AM THIS MORNING/
Early this morning: No changes to the forecast through sunrise.
High pressure remains in control with only very thin cirrus passing from west to east overhead. Radiational cooling conditions are probably better tonight than last night as winds will remain completely calm overnight. Temperatures are already dropping below freezing inland, especially across southeast GA.
Since the growing season has been declared over, no frost/freeze headlines. Steam fog will be possible near marshes, creeks, and streams later tonight, but no significant visibility reduction is expected.

SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY/
Southwesterly flow aloft will prevail through the period, with a shortwave trough rippling through Friday into Saturday. At the surface high pressure initially anchored over the southeastern states on Thursday will shift offshore as a cold front approaches the region. This cold front will likely become stalled in the vicinity of the forecast area through the weekend, yielding unsettled weather through the period. The southwesterly flow aloft will allow warmer temperatures and moisture to advect into the region. High temperatures on Thursday will likely only reach into the low to mid 60s, increasing to the low to mid 70s on Friday and Saturday.
Overnight lows will follow a similar warming pattern. PWATs initially >0.5 inches on Thursday will surge to around 1.5 inches by Friday afternoon. Isolated to scattered showers are possible Friday afternoon, increasing in coverage through the overnight period and into Saturday. Saturday appears to be the wettest day of the weekend, especially further inland. Rainfall totals Friday through Saturday range between 1 and 2 inches, with the higher amounts further inland. Additionally, there is a slight chance of thunder across the region Saturday afternoon as instability increases slightly.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/
The southwesterly flow aloft will continue into Monday, when an upper level trough swings eastward and pushes off the Eastern Seaboard. With the surface cold front still stalled in the vicinity the unsettled pattern will continue into early next week when a stronger cold front will push through the region.
High pressure is expected to build in behind the front and prevail through the remainder of the period. Scattered to widespread showers are forecast for Sunday and into Monday, with drier conditions moving in Monday night. Instability looks like it could remain favorable for a grumble of thunder on Sunday, a slight chance of thunder has been included in the forecast for Sunday afternoon, mainly across southern zones. Temperatures will remain above normal Sunday, with highs in the low to mid 70s. Monday will return to near normal with highs in the mid 60s, with below normal temperatures expected through the remainder of the period as high pressure builds in. Overnight lows will follow a similar trend.

AVIATION /06Z THURSDAY THROUGH MONDAY/
VFR conditions will prevail at KCHS, KJZI, and KSAV through 06z Friday.

Extended Aviation Outlook: Showers are possible at all terminals both Friday through Sunday, bringing the risk of both cig and vis restrictions at all three terminals.

MARINE
Tonight: The trough will dissipate early, while another more typical trough forms over the Gulf Stream as we go through the night. The main feature though will be a 1024+ mb high covering the Southeast states. With the orientation of the high and land breeze influences developing overnight, all winds will become northerly at 10 kt or less. Not much wave action, with heights just 1 or 2 feet. Maybe a little steam fog occurring late at night due to the cold air mass, light winds, and RH values of 85-100%.

Thursday through Monday: High pressure will prevail over the marine waters through Friday, yielding generally SE winds less than 10 knots. Seas should average 2 to 3 ft. A cold front will approach the region and then stall in the vicinity through the weekend and into Monday. Winds will generally be out of the SW 10 to 15 knots, with seas averaging 3 to 4 ft. While conditions are likely to stay below Small Craft Advisory criteria levels, there is a threat for sea fog Friday night through Sunday as a warm air mass (high temperatures around 70F) moves over the cooler marine waters (SSTs around 60F).
