SYNOPSIS
High pressure will extend into the area through Tuesday. A cold front could affect the area around the middle of next week.
NEAR TERM /THROUGH TONIGHT/
The coldest temperatures as of 7 AM this morning were Walterboro at 36F and Bonneau at 37F. The coldest in Georgia was 40F at Millen.
Today: A broad trough aloft will continue to pull further away, allowing for steady height rises as ridging starts to approach from the west. High pressure at the surface that is initially centered near the southern Appalachians will split into two centers this afternoon. One will be near the southeast Georgia coast, with the other near the Florida panhandle. Pwat down near 1/4 to 1/3 inch and strong March sunshine will allow for a fast recovery of temperatures. We used a blend of the low level thickness forecast with the MOS and NBM consensus, arriving at the lower 70s just about everywhere. The barrier islands will be in the mid and upper 60s due to an afternoon sea breeze. In addition, a deep offshore flow this afternoon will allow for dew points to drop to the upper 20s to mid 30s. This equates to minimum RH values as low as near 20 or 25%.
Tonight: High pressure is found over south Georgia and north Florida, as flat ridging moves in aloft. Winds will become light or calm in most places, and that along with mostly clear or clear skies (aside from some late night cirrus), will produce good radiational cooling. This supports lower and middle 40s inland, with upper 40s and lower 50s closer to the coast.
SHORT TERM /SATURDAY THROUGH MONDAY/
Surface high pressure across the Southern Atlantic, extending into the Southeast US coast, will remain nearly stationary through the short-term period. This will make for a seemingly rare rain-free and warm weekend. Skies should be clear for much of the weekend, with a few periods of thin cirrus. Cloud coverage will increase a bit on Monday with a slight uptick in upper level moisture, but still expect some sunshine at times nonetheless. Each afternoon should also bring a nice progressive sea breeze as the temperature difference increases between land areas and the relatively cooler shelf waters. Temperatures will be trending warmer through the period as broad ridging aloft prevails and low level thickness increases. Saturday will top out in the mid to upper 70s, increasing to the upper 70s/low 80s Sunday, and the low to mid 80s for Monday.
Similarly, lows will trend warmer as Saturday night drops into the low to mid 50s and Sunday night into the upper 50s/low 60s.
LONG TERM /MONDAY NIGHT THROUGH THURSDAY/
Ridging aloft, high pressure at the surface, and above normal temperatures will continue through Tuesday. A cold front is then expected to approach the forecast area from the west Tuesday night and is currently progged to push offshore Wednesday evening. The front looks quite progressive and should bring a quick shot of showers and possibly isolated thunderstorms. Model guidance suggests there will be plenty of deep layer shear, though very little instability. So, it is possible there could be at least a low end severe threat on Wednesday. Temperatures will cool back to near or slightly below normal behind the front for the end of next week.
AVIATION /11Z FRIDAY THROUGH TUESDAY/
VFR at KCHS, KJZI and KSAV through 12Z Saturday.
Extended Aviation Outlook: VFR conditions will prevail.
MARINE
Today: High pressure will continue to build into the waters this morning. With steady pressure climbs, and weak cold advection, northerly winds will be as high as 15 or 20 kt, plus some higher gusts. There are Small Craft Advisories for the Georgia waters, where wind gusts have been as high as 25-29 kt early on at the Savannah Entrance Light and Buoy 41008. Once cold advection wanes by late morning, the advisory on the nearshore Georgia waters will end. Then as a more relaxed gradient develops this afternoon, and allows for sea breeze circulations, it'll also put an end of the advisory on the Georgia waters beyond 20 nm out.
Tonight: High pressure remains firmly in control. Winds will be a little higher on the Charleston County waters early on, with lingering sea breeze influences and a slightly tighter gradient.
But after that, winds will be no more than 10 or 15 kt, mainly out of the SW most of the night, with subtle land breeze circulations late.
Saturday through Monday: Surface high pressure across the Southern Atlantic and across the local waters will result in persistent southwesterly winds through the period. Wind speeds will average 10- 15 kt, but will briefly surge higher at times as the sea breeze develops each afternoon. Also, the gradient between the offshore high and an inland surface trough will support stronger winds at times. Marginal Small Craft Advisory conditions are expected in the Charleston County nearshore waters for a brief period late Saturday evening with gusts approaching 25 kt. Seas will mostly range 2-3 ft, with some 4 footers further offshore.
Tuesday through Wednesday: Winds/seas will begin to increase/build Tuesday ahead of an approaching cold front, which is currently progged to push offshore Wednesday evening. Southwest gusts around 25-30 kt are possible across all marine zones, including the Charleston Harbor, beginning Tuesday evening through at least Wednesday. Seas around 3-6 ft will be common in the local waters as well. Small Craft Advisories will likely be needed.
