SYNOPSIS
A cold front will approach from the northwest tonight and move through Friday morning. High pressure returns for the weekend, then another cold front will move through Monday. High pressure will build back in behind the front.

NEAR TERM /THROUGH TONIGHT/
Today: Morning convection induced by the shortwave aloft has pushed well offshore, and has moved east of the marine zones.
Will see a lull in convective activity into mid-afternoon, when isolated showers/tstms may begin to develop inland well ahead of a surface front. A lagging shortwave is poised upstream across the Deep South and along the central Gulf Coast. The flow will flatten out into the afternoon and the main portion of the shortwave looks as though it will track to the southeast and pass south of the forecast area. At the surface, the subtropical high will continue to extend westward into the area which will place the forecast area in between the high to the east and an approaching front to the west. The main forecast challenge concerns how much convective coverage there will be in the afternoon and into the evening. Hi-res model solutions are quiet consistent from run to run in producing little, if any, convection this afternoon. Perhaps this is a result of a little subsidence in the wake of the departing shortwave energy, as well as warm profiles noted in model soundings. Overall, these hi-res models have done reasonably well the last few days showing considerably less coverage compared to global models and current thinking is that this will continue today. Therefore, we have lowered the forecast to include just isolated thunderstorms this afternoon. The near storm environment today is similar to the last few days where DCAPE values are progged to be up around 1,000 J/kg. Also of note in model soundings today, flow in the 700-850 mb layer will be on the order of 25-30 knots. So, if a storm can initiate and get going, it certainly has the potential to produce damaging wind gusts.
However, the expected lack of coverage will help keep the overall threat low.

Surface winds will take on more of a westerly component today which is usually a recipe for warmer temperatures. Thicknesses will also increase, setting the table for a very warm day. The forecast calls for low to mid 90s, but heat index values should only top out in the upper 90s thanks to dew points mixing out a bit in the afternoon.

Tonight: With convection likely holding off until it develops upstream across the South Carolina Midlands and moves in during the evening hours, the first part of the tonight period will likely be the most active. We have the highest chances during the mid to late evening hours, favoring southeast South Carolina. It is possible there will be a low end severe threat with damaging wind gusts being the main risk. Any ongoing convection should shift offshore by the early morning hours, and the rest of the overnight should be dry for land areas. It will be a mild night, with lows only falling into the low 70s in most locations.

SHORT TERM /FRIDAY/
A cold front will move through Friday morning with drier air gradually building in. Subsidence will overspread southern SC during the afternoon, likely preventing convection from developing. There is a slight chance that an isolated shower or tstm will develop along the GA coast in the afternoon where a weak sea breeze coincides with the cold front and slightly greater moisture. Downslope flow will push highs into the lower 90s.

Broad upper ridging will occur Saturday into Sunday while dry high pressure overspreads the area at the surface. Surface dewpoints will drop into the 50s inland, with lower 60s near the coast, resulting in a noticeable change in airmass despite high temps in the low to mid 90s under downslope flow.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/
Another cold front will drop through the area Sunday night, then stall near or just south of the area. Moisture will gradually increase across the Southeast early next week, and diurnal convection will return.

AVIATION /14Z THURSDAY THROUGH MONDAY/
VFR conditions will mostly prevail at KCHS, KJZI, and KSAV through 12z Friday. Most of the day is expected to be dry and the best chance for thunderstorms will come this evening, mainly at KCHS and KJZI. We have added in VCTS from 01-04z at these sites, but left any mention out of KSAV.

Extended Aviation Outlook: VFR.

MARINE
Today and tonight: South to southwest flow will prevail across the local waters today, mostly in the 10-15 knot range.
Enhancements along the land/sea interface are expected with the afternoon sea breeze, producing gusts up to around 20 knots.
Overnight, southwest flow will increase as the gradient tightens when the local waters get pinched between the high to the east and a front approaching from the west. Winds around 15 knots will be more common, with 15-20 knots possible for a period of time in the outer Georgia waters and the Charleston County waters. Seas should average 2-3 feet today, increasing to be 3-4 feet overnight.

Southerly flow on Friday will turn to the W Friday night, then N on Saturday behind a cold front. The pattern quickly reverts to a typical southerly flow by Saturday night and Sunday as Atlantic high pressure rebuilds.
