Near Term. /through Monday night/ .

Strengthening high pressure will build to the north Tonight. A light north flow will result from this pattern. The airmass is quite dry, as seen in afternoon dewpoints. The combination of the clear skies, cold advection, light winds and dry air will yield a cold night Tonight. Frost will be expected inland, with a frost advisory necessary for inland SE GA and Suwannee valley of NE FL. A few spots could briefly reach freezing.

The high will build just to the north Monday, with sunny skies expected. Due to the position of the high, the flow will become more onshore. Temperatures will be a little milder than Today. Flow across the inner coastal waters, where sea surface temperatures are in the upper 50s, will keep readings coolest at the coast.

Strong high pressure will be centered just north of the forecast area Monday night keeping skies clear. This will be another colder than normal night, with an inland frost expected. With the flow more onshore across NE FL, readings will be lowest over SE GA.

Short Term. /Tuesday through Thursday/ .

The high will build to the northeast Tuesday, then slowly move further to the northeast through Thursday, but the ridge will continue to extend across forecast area. Moisture will slowly increase through this period yielding partly cloudy skies. Temperatures will moderate this period, with readings returning to near normal levels by Wednesday, and above for Thursday.

Long Term. /Thursday night through Sunday/ .

The high will slowly drift a little further to the northeast through Saturday and weaken, with the ridge continuing to extend across area. Enough moisture in this pattern for partly cloudy skies, but the dry weather will continue through Saturday. Temperatures will continue to moderate through Saturday, with 80s common away from the coast Saturday afternoon.

A cold front is expected to move into region from the north northwest Sunday. Current frontal timing would keep much of the day dry, but with an increase in cloud cover. Temperatures will continue above normal.

Marine.

High pressure will build to the northwest Today, then just to the north on Monday. The high will build to the northeast Tuesday. The high will slowly move to the east northeast through the week into next weekend, with ridging extending west across the region.

Rip Currents: SE GA: Moderate through Monday NE FL: High through Monday
