Synopsis for the Suwannee River to Okaloosa-Walton County Line out to 60 nm - GMZ700
302 AM EST Mon Jan 20 2020

Borderline small craft criteria will continue through Wednesday as the deep high pressure system slides east into the Atlantic. As a result, wave heights will be in the 2-5 ft range with the highest waves in our far offshore areas. Moderate southeasterly flow will develop once again ahead of the next cold front.

300am EST Monday Jan 20 2020

.NEAR TERM [THROUGH TONIGHT]... In general, high pressure will prevail at the surface with a large eastern CONUS trough amplifying aloft. With the exception of some passing mid-level clouds tonight, skies should remain clear.

With the upper trough in place and Cold Air Advection at the surface, high temperatures will fail to reach the 50 degree mark across the Panhandle, southeast Alabama, and portions of southwest Georgia today. Across the Big Bend and Suwannee Valley, expect highs in the low to mid 50s. Overnight, winds will be light enough to allow temperatures to fall into the middle and upper 20s region-wide. Due to the light winds, however, apparent temperatures will fall to the low to mid 20s. A wind chill advisory may eventually be necessary across portions of the Panhandle and SE AL.

.SHORT TERM [TUESDAY THROUGH WEDNESDAY]... The cold regime continues through Wednesday as light north to northeasterly flow will continue to advect cold and dry air across the area. High temps will stay in the mid- to upper 40s over SE AL and SW GA on Tuesday afternoon. Meanwhile, areas along the coast will experience slightly higher temps.

For Wednesday morning, expect temps to drop into the upper 20s across the entire area. Low to mid 30s will be more likely for areas near the immediate coast or large bodies of water. Light northeasterly flow should stop radiational cooling near the surface, however, given the anomalously dry airmass in place, any area where the wind does goes calm for a few hours, could see temps drop into the mid to low 20s.

Long Term - Wednesday Night Through Monday
Expect a warming trend as easterly to southeasterly flow begins to develop out ahead of the next cold front. Chance of precipitation will begin to increase on Thursday with showers an a few isolated thunderstorms lingering through Saturday. Moderate southeasterly flow ahead of the cold front will develop across our offshore zones on Friday. The cold front will bring another, albeit weaker, cool down starting Saturday afternoon. The threat for severe weather is low at this time.

Marine
Borderline small craft criteria will continue through Wednesday as the deep high pressure system slides east into the Atlantic. As a result, wave heigheights will be in the 2-5 ft range with the highest waves in our far offshore areas. Moderate southeasterly flow will develop once again ahead of the next cold front.

Fire Weather
Dry and cool conditions are forecasted over the next couple of days. While RH's may reach critical thresholds from time to time, below criteria winds will preclude Red Flag conditions.

Hydrology
Another round of showers is expected starting Thursday ahead of the next cold front. Widespread rain accumulations will be around 1 inch, however, higher amounts will be possible. We will continue to monitor the rainfall potential through the week.

Moderate flooding is ongoing on the Apalachicola River near Blountstown.
