SYNOPSIS
High pressure will prevail through Thursday, with a cold front passing through the area Friday. High pressure will return to the region this weekend and prevail into early next week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
A mid level trough passing across the region will exit offshore this evening, leaving northwest flow aloft for the latter half of the night in advance of a building ridge. At the surface, a ridge of high pressure will continue to extend into the area.
Clear skies are expected for much of the overnight as mid/higher level clouds will exit early. This will support good radiational cooling, especially inland. Lows are forecast to range from the lower/mid 30s inland to around 40/low 40s at the coast.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/
Wednesday and Wednesday night: Upper ridging aloft will build in across the region as high pressure prevails at the surface. Expect clear skies and quiet conditions with temperatures a few degrees below normal. Highs are forecast to reach the low 60s across most of the forecast area, with some mid 60s possible for southeast Georgia.
Overnight, lows should dip into the mid 30s across the inland tier ranging to the low 40s along the coast.

Thursday through Friday: This will be the busiest portion of the forecast period thanks to the approach and passage of a cold front Thursday night through Friday. Ahead of the front on Thursday, conditions will be quiet and the main change will be the arrival of return flow and warmer temperatures. Highs are forecast to reach the upper 60s and low 70s away from the coastline. Thursday night, the cold front will begin to approach from the west and deep moisture will surge into the area ahead of it. Precipitable water values are progged to increase into the 1.00-1.25" range by sunrise Friday. An area of showers will push into the forecast area late Thursday night and work to the east through Friday afternoon. Rainfall amounts are not expected to be significant, with less than 0.25" expected. There continues to be the chance for some weak instability on Friday, and we have maintained the mention of a slight chance of thunderstorms.
However, the overall severe threat looks to be quite low. Perhaps most impactful will be gusty winds developing late Thursday night ahead of the front and continuing into Friday afternoon. At the peak, wind gusts around 25 mph can be expected across the entire area, with 30 mph likely along portions of the immediate coast. The front will shift offshore in the late afternoon hours and the coverage of showers will diminish.

Lake Winds: A cold front will approach the area late Thursday night and pass through on Friday. Strong, gusty winds are expected to develop across Lake Moultrie late Thursday night and continue into Friday afternoon. Gusts to 25 knots will be possible, and a Lake Wind Advisory could be needed.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/
Beginning Friday night, the cold front will be positioned well offshore and high pressure will steadily build in through Saturday.
A secondary front, or surface trough, will drop through the area by Saturday night and high pressure with quiet conditions will prevail into early next week. Behind the Friday/Friday night front, there will not be a significant airmass change as temperatures for the weekend are expected to be near normal. However, as we move into early next week, model guidance suggests a significant warm up is on the way with low to mid 70s for Monday and even mid to upper 70s by Tuesday.

AVIATION /20Z TUESDAY THROUGH SUNDAY/
VFR conditions are expected at KCHS/KJZI/KSAV terminals through 18Z Wednesday.

Extended Aviation Outlook: A brief period of MVFR ceilings and rain showers will be possible on Friday as a cold front passes through the region. Gusty winds are expected late Thursday night through Friday.

MARINE
Tonight: Ridge of high pressure will continue to extend inland tonight, while low pressure spins well off the East coast. This pattern will maintain north to northeast flow with speeds 10-15 knots, perhaps topping out 15-20 knots across the Charleston County and outer Georgia waters late near daybreak. Seas peak 3-5 feet late.

Wednesday through Sunday: Elevated north to northeast flow will continue through most of Wednesday before diminishing significantly Wednesday night. Seas will be elevated thanks to the moderate flow, with 6 ft seas likely in the outer GA waters. A Small Craft Advisory will likely be needed in the outer GA waters, leading into the main marine event coming Thursday night onward. Starting Thursday, winds will become southwesterly ahead of an approaching cold front and will ramp up into the evening. The worst marine conditions will occur late Thursday night through Friday as strong southwest flow spreads across the local waters ahead of an approaching cold front.
Small Craft Advisories will almost certainly be needed for all the waters including Charleston Harbor. In fact, the likelihood of gale force gusts is increasing for Friday morning through early Friday afternoon. The primary areas of concern are the Charleston County waters and the outer GA waters, and a Gale Watch/Warning could eventually be needed. Winds will turn westerly and then northwesterly behind the front Friday night and continue through Saturday. All marine headlines should come to an end Saturday with much quieter conditions expected through the rest of the weekend.
