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 THURSDAY MORNING/
At 1030 PM: Latest observations indicated that temperatures ranged from the mid 30s inland to the low 40s to upper 30s along the coast. IR satellite indicates contrails and thin cirrus over and upstream of the forecast area. High clouds should gradually increase through the rest of the night, but remain thin. Given a mostly clear sky and light to calm winds, temperatures 29-32F expected across most communities west of US-17, with 33-37F most elsewhere, except for a few places close to 40F near Lake Moultrie, parts of the Charleston-North Charleston metro, and on the barrier islands.

Since the growing season has been declared over, no Frost/Freeze products will be required.

Maybe a little steam fog late due to the higher RH and less wind than last night.

SHORT TERM /6 AM THURSDAY 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 /03Z THURSDAY THROUGH MONDAY/
VFR conditions will prevail at KCHS, KJZI, and KSAV through 00z 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
This evening: The remnants of the surface trough across the Charleston County waters will cause NE winds as high as 10 or 15 kt on these waters, while elsewhere the winds will be mainly NW at 5 to maybe 10 kt.

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).
