Area Forecast Discussion National Weather Service Jacksonville FL 942 PM EST Sun Mar 7 2021

. INLAND FROST TONIGHT .

UPDATE.

A cool, dry airmass was in place inland with elevated NNE winds near the coast between high pressure building north of the region and a coastal trough offshore of the central FL Atlantic coast. Mostly clear skies will prevail tonight as the surface ridge settles farther south across GA with some FEW to SCT passing high cirrus as a weak upper level trough crosses the region.

Best radiational cooling conditions due to light winds will focus across inland areas of SE GA and the Suwannee River Valley of NE FL where widespread frost is expected toward sunrise Monday morning as lows fall into the mid 30s with a few locales across inland SE GA potentially nearing the freezing mark briefly around sunrise.

Patchy frost is possible in wind sheltered areas of Alachua, Putnam, western Clay & inland Duval/Nassau where temps will generally range in the upper 30s . with temps toward the Atlantic only falling into the low/mid 40s under elevated NNE flow where frost is not expected.

MARINE.

Advisory conditions continue for all waters tonight less the nearshore GA zones where Exercise Caution caution was in place. Winds and seas will fall below headline levels into Monday as high pressure builds over the region.

Rip Currents: High Rip Current Risk for NE FL coast again Monday, with Moderate for SE GA.

HYDROLOGY.

Minor flooding continued along portions of the Altamaha, Satilla, Santa Fe and lower Suwannee rivers. An extended period of dry weather is expected this week.

PREV DISCUSSION [736 PM EST].

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.

AVIATION. [Through 00Z Tuesday]

VFR conditions through the period. NNE winds tonight < 3 kts inland to 5-9 kts. Winds become breezy around 14-15z at coastal terminals again Monday with gusts 15-20 kts by midday.
