SYNOPSIS
A strong cold front will cross the area this evening, followed by high pressure through late this week.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/
Early this evening: Other than a small corridor of weak instability along the upper Charleston County coast, the atmosphere has mostly stabilized and the thunder potential has ended. We did have one convective element move into southeast Georgia and ride along the Georgia coast and up the South Carolina coast. Other than some wind gusts up to 40-45 mph, no severe weather occurred and the severe threat has come to an end. Surface analysis shows that the cold front is still back to the west and is right on the door step of the forecast area. The front will cross the region through the early morning hours, and will bring with it a round of showers and a strong pop of wind as the wind direction turns westerly. Upstream observations indicate that a brief period with wind gusts into the 25-30 mph range is likely. This should be roughly around midnight. Late tonight, skies will start to clear from the west and much cooler air will filter in. Monday morning lows are forecast to reach the upper 30s inland, ranging to the low to mid 40s closer to the coast.

Lake Winds: A strong cold front will move across Lake Moultrie this evening. As it does, winds will turn westerly and quickly increase, with wind gusts into the 25-30 knot range for a period of time. A Lake Wind Advisory remains in effect through 1 am.

SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/
Monday: The strong cold front will be well offshore by sunrise Monday with strong post-frontal cold air advection (CAA) in progress. The intensity of the CAA will wane through the day with 850 hPa temperatures settling into the 2-5C range by afternoon. There will be somewhat of a weak downslope component in the lee of the southern Appalachians, but it will still be a chilly day despite full insolation. Highs will only reach within a degree or two of 55 area wide with early breezy conditions gradually diminishing as the day progresses. Sunday night will be a bit chilly under clear skies. The boundary layer may fully decouple across the interior while winds stay up a bit along the coast where the pressure gradient is progged to tighten a bit overnight in response to the center of the surface high bridging the Blue Ridge. Favored the cooler side of the guidance across the interior and closer to the guidance mean at the coast. Lows will range from around 30 well inland adjacent to the CSRA and Southern Midlands to the mid 40s along the beaches where northeast winds will have a bit more of a moderating influence.

Tuesday and Wednesday: High pressure will dominate through this period as a mostly zonal flow prevails aloft. A weak coastal trough will dry and form just offshore by Wednesday, but any associated shower activity should remain well offshore. While the main low-level moisture channel will be directed into Northeast Florida, there could be a gradual increase in cloud cover with some degree of marine-based stratocumulus pushing inland, mainly across the coastal counties (especially coastal Georgia) coupled with thickening cirrus aloft. Temperatures will begin to slowly moderate both days with highs warming into the mid-upper 50s Tuesday with upper 50s/lower 60s Wednesday. Lows Wednesday morning will range from around freezing well inland to the upper 40s/near 50 at the beaches.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/
Quiet conditions will prevail for much of the week. The forecast becomes a bit more uncertain Friday into Saturday some data suggesting a storm system will develop over the Gulf of Mexico and impact parts of the Southeast U.S. coast during the upcoming weekend. The forecast was closely aligned with the 10/13z NBM for now until trends can become better established.

AVIATION /23Z SUNDAY THROUGH FRIDAY/
The 00z TAF period will start out with VFR conditions and no rain at KCHS, KJZI, and KSAV. However, a cold front is situated just to the west, and it will move through the TAF sites in the 03-05z time period. The front will bring an area of showers as well as a quick increase in wind speed. Gusts into the 25-28 knot range can be expected. Also, a period of MVFR (or possibly IFR) ceilings is anticipated. VFR conditions should return by the 08-10z time range and then prevail through the remainder of the TAF period.

Extended Aviation Outlook: There are no concerns at this time.

MARINE
Tonight: The cold front will push through the region around midnight tonight, with a surge in winds expected across all marine zones as strong CAA develops behind the front. Winds are forecast to gust between 35 to 40 knots and Gale Warnings have been issued for all marine waters outside of the Charleston Harbor through early Monday morning.

Monday through Friday: Conditions will rapidly improve across the marine area Monday as high pressure builds in from the west and post- frontal CAA wanes. A modest northeast flow event will develop by mid- week as the pressure gradient tightens in response to sprawling high pressure building into North Carolina and the formation of a subtle coastal trough just offshore.
Both winds and seas will respond with a return to Small Craft Advisory levels possibly as early as Wednesday which will likely linger into Friday.

EQUIPMENT
KCLX remains operational, but level 2 data is not being distributed to external users due to an internal hardware failure. We are still awaiting the arrival of new parts to resolve this problem. Until then, level 2 data will not be available. Radar data is available for all connected AWIPS users. Level 3 data is also available for some external users.

CHS WATCHES/WARNINGS/ADVISORIES

SC...Lake Wind Advisory until 1 AM EST Monday for SCZ045.
MARINE...Small Craft Advisory until 6 AM EST Monday for AMZ330.
Gale Warning until 3 AM EST Monday for AMZ350-352-354.
