SYNOPSIS
A cold front will move through late today, followed by high pressure into Friday. A storm system will affect the area this weekend, followed by high pressure from the north next week.

NEAR TERM /UNTIL 6 AM THURSDAY MORNING/
A short wave trough will pull east through the area, with considerable dry air and NVA to follow in its wake. By daybreak heights aloft will begin to rise as ridging approaches from the west. Showers are just about done with given a Normalized CAPE less than 0.1, poor lapse rates, and limited CAPE. We still have slight chance PoPs in some places through 12-1 am, but that's it. The air mass behind the front does have a little cooler air with it, as we look for lows down in the lower and middle 60s inland, upper 60s near the coast. Closer to sunrise some low stratus could form to the north and advect toward I-26 after dawn.

SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/
A relatively progressive pattern will exist during the short term period. A shortwave ridge will move through on Thursday, yielding warm temps and dry weather. Highs expected to be in the mid to upper 80s.

A deepening southerly flow will bring an increase in moisture on Friday. A shortwave trough will lift northeast through the area late Friday, potentially bringing a few showers or tstms in from the west Friday afternoon.

A longwave upper trough will shift into the eastern United States Friday night and Saturday. A tropical airmass will overspread the area with PWATs approaching 2". A weak warm front will lift north through the area Friday night, then a potent shortwave will move through on Saturday. Fairly widespread showers and thunderstorms are expected during this period with many areas potentially receiving more than 1" of precipitation.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/
The upper trough axis will swing through on Sunday, potentially producing a few showers or tstms. Then, dry and warm weather expected as an upper ridge gradually builds from the west.

AVIATION /02Z THURSDAY THROUGH MONDAY/
KCHS/KJZI: Nearby -SHRA will end by 04Z, and that's the last of any rainfall with the latest TAFs. There might be some low stratus for a few hours between 10Z and 14Z Thursday. But the probabilities are too low, so prevailing VFR through 00Z Friday.

KSAV: Maybe a brief -SHRA nearby early tonight, otherwise VFR will prevail.

Extended Aviation Outlook: Showers and thunderstorms could bring flight restrictions to all terminals Saturday and Saturday night as a low pressure system impacts the region.

MARINE
Tonight: A cold front will continue to push into and through the waters, resulting in winds that are W or WNW as high as 15 or 20 kt. With the offshore trajectories the initially elevated seas will slowly start to come down, and are mainly 3 or 4 feet. The risk for any strong t-storms has ended for the night.

Thursday through Monday: Conditions through the period are expected to remain below Small Craft Advisory criteria. High pressure will build in at the surface on Thursday, then a cold front pushes through on Saturday. High pressure returns early next week.

CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
