SYNOPSIS
A cold front will move offshore later today, with high pressure building in for tonight. Another dry cold front will drop through late Tuesday night, followed by high pressure through Saturday. The next weather system will arrive late in the weekend.

NEAR TERM /THROUGH TONIGHT/
Today: Aloft, the day will begin with southwest flow ahead of a well defined shortwave that will deamplify as it tracks eastward. As the base of the trough crosses the Appalachians and shifts towards the Mid Atlantic, the flow across the forecast area will turn more westerly. At the surface, the leading cold front will shift offshore early this morning followed by a secondary that will approach from the west in the afternoon.
With the flow aloft remaining persistently southwest for the first part of the day we will maintain a decent amount of mid and high level clouds before they shift offshore more into the afternoon as the shortwave aloft passes by to the north. Ahead of the approaching boundary this afternoon, winds will strengthen and become breezy with frequent gusts up to around 20 mph. The benefit of the timing of the secondary cold front is that we will get one more day with above normal temperatures.
Highs are forecast to reach the low to mid 70s.

Tonight: As the secondary front shifts offshore in the evening, we will finally get a solid airmass change through the overnight. Cloud cover will decrease, though clear skies aren't anticipated due to lingering jet induced cirrus. Lows are forecast to fall into the low to mid 40s inland and the upper 40s along the immediate coast.

SHORT TERM /TUESDAY THROUGH THURSDAY/
Upper trough will amplify over the eastern U.S. Tuesday into Tuesday night as a shortwave dives across the Ohio/Tennessee Valleys and then through the Carolinas, before exiting offshore on Wednesday. An associated surface low will take a similar track, dragging a reinforcing cold front through the area early Wednesday. Cool high pressure will build in behind it, eventually shifting overhead on Thursday. Very little moisture available, so a dry forecast persists. Enhanced pressure gradient behind the departing front will lead to gusty northwest winds on Wednesday.

Temperatures in the low/mid 60s on Tuesday will cool several degrees to the upper 50s for Wednesday and Thursday. Lows will be chilliest Wednesday night with some inland locations dropping to or below freezing.

LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/
High pressure will shift offshore for Friday and Saturday. A coastal trough could lift north as a warm front on Saturday and generate some shower activity, but kept rain chances confined to the coastal waters with a dry forecast over land for now. A cold front will then approach from the west Saturday night, before crossing the area on Sunday. This system should bring at least scattered showers to the area.

AVIATION /09Z MONDAY THROUGH FRIDAY/
The first 6 hours or so of the 06z TAF period will be complex thanks to the presence of an expanding blanket of IFR stratus across much of southeast Georgia and southeast South Carolina.
In fact, IFR ceilings have settled in at KCHS and KJZI and are very close at KSAV. Current thinking is that IFR conditions won't last for a prolonged period of time, but will likely take until 09-10z before improving to VFR. West to west-southwest winds will become breezy this afternoon, with frequent gusts up close to 20 knots expected.

Extended Aviation Outlook: VFR. Gusty winds are possible on Wednesday.

MARINE
Today through tonight: Winds will start off the day light and less than 10 knots before increasing into the afternoon as a front approaches from the west. Wind speeds will increase into the 10-15 knot range from the southwest during the afternoon. A modest surge will occur from the evening into the early morning hours as winds turn westerly and increase up to around 15 knots.
Seas will mostly average 2-3 feet, with up to 4 feet possible in the outer waters.

Tuesday through Saturday: Winds and seas will increase Tuesday night into Wednesday behind a dry cold front. Small Craft Advisories will be likely for at least portions of the coastal waters during this time frame. Conditions will improve late Wednesday night into Thursday. No additional marine concerns expected through Saturday as high pressure prevails.
