SYNOPSIS
A dry cold front will drop through the area tonight, followed by high pressure through Saturday. The next weather system will arrive Saturday night into Sunday. High pressure should return early next week.
NEAR TERM /THROUGH TONIGHT/
Forecast appears on track with no significant changes made for the mid morning update.
Previous discussion...
Today: Aloft, zonal flow will prevail across Georgia and the Carolinas as a trough dives southward out of the Upper Midwest and toward the Tennessee Valley. At the surface, the forecast area will be situated between one cold front well offshore and a reinforcing front quickly approaching from the mid Mississippi Valley. We will continue to see scattered cirrus pass across the region through the day, but should still see plenty of sun.
Surface winds will begin the day northwesterly before backing to westerly through the afternoon. Low level thickness progs support highs right around the mid 60s, and we should see enough insolation and westerly flow to achieve that.
Tonight: The upstream cold front will continue to approach through the evening and is timed to move offshore by around sunrise Wednesday. We will maintain 5-10 mph of wind through the night thanks to the gradient associated with the approaching and passing front. Lows are forecast to fall into the low 40s across most of the forecast area, with a few upper 30s across the interior counties.
SHORT TERM /WEDNESDAY THROUGH FRIDAY/
Mid level trough axis will shift offshore on Wednesday. At the surface, the forecast area will be sandwiched between low pressure exiting to the east and high pressure building in from the west. A tight pressure gradient between these two features will lead to gusty northwest winds. Some low 20 kt gusts will be possible over Lake Moultrie. Even with full sunshine, cold air advection will limit highs to the upper 50s/near 60. Low temperatures will range from around 30 across the far interior to upper 30s/near 40 near the immediate coast.
The surface high will drift overhead on Thursday, then shift into the Atlantic for Friday. No weather concerns with a dry forecast in place. Highs mainly in the mid/upper 50s Thursday will moderate close to normal on Friday. Lows Thursday night will be in the 30s, except low/mid 40s at the beaches and in Downtown Charleston.
LONG TERM /FRIDAY NIGHT THROUGH MONDAY/
High pressure over the western Atlantic will persist into Saturday, although a coastal trough could lift north as a warm front later in the day in advance of an approaching low pressure system. Shower activity largely looks to stay over the waters, but a few could brush onshore. Rain chances will really ramp up Saturday night into Sunday as an upper trough shifts into the eastern U.S. and brings a cold front through the region. Still some differences to work out, but conditions will support healthy rain chances. Temperatures will be near to above normal.
AVIATION /18Z TUESDAY THROUGH SATURDAY/
VFR conditions will to prevail at KCHS, KJZI, and KSAV terminals through 18z Wednesday.
Extended Aviation Outlook: VFR. Gusty winds around 15-20 kt are possible at the terminals on Wednesday.
MARINE
Today through tonight: Northwest winds this morning will become westerly this afternoon and increase into the 10-15 knot range.
Then overnight, winds will steadily strengthen as the gradient tightens and cold advection allows for deeper mixing profiles across the local waters. By sunrise Wednesday winds across the nearshore waters are expected to be 15-20 knots with gusts to 25 knots. The outer waters should be in the 20-25 knot range.
Therefore, we have started Small Craft Advisories for all zones outside Charleston Harbor by late tonight. Seas will be 2-3 feet through this evening, increasing to 3-4 feet by late tonight with up to 5 feet in the outer Georgia waters.
Wednesday through Sunday: Tight pressure gradient with high pressure building in from the west will result in gusty northwest winds over the coastal waters on Wednesday. A Small Craft Advisory will be ongoing for all waters outside of the Charleston Harbor which will persist through the day and into the first part of Wednesday night. It is certainly possible an Advisory will be needed for the Charleston Harbor, but have opted to hold off for now and let later shifts assess.
Conditions will vastly improve for Thursday as high pressure shifts overhead with no additional concerns through Saturday.
Winds and seas will increase late Saturday night into Sunday with the next frontal system. Small Craft Advisories appear likely at this time.
