GMZ700 Synopsis For The Suwannee River To Okaloosa-walton County Line Out To 60 Nm 335 Am Est Tue Nov 28 2023
Synopsis..
borderline advisory level conditions persist until around noon cst across waters west of apalachicola while cautionary winds and seas continue over apalachee bay via brisk northerly winds. Surface high pressure moving in brings about lighter offshore breezes below headline criteria through mid-week before an approaching area of low pressure from the western gulf brings about hazardous boating late Thursday and Friday. Chances for Thunderstorms also return to the forecast heading into the weekend with a rainy pattern likely until Monday afternoon.

...FREEZE WARNINGS NOW IN EFFECT ACROSS MOST OF THE TRI-STATE AREA FOR WEDNESDAY MORNING...
NEAR TERM
(Today and tonight)
Issued at 420 AM EST Tue Nov 28 2023
1027mb surface high pressure is expected to quickly advance towards the southeast US underneath fairly zonal flow aloft. Clouds this morning will decrease from west to east as high level moisture pushes east and dry air and subsidence strengthens below 400mb. High pressure settles just north and west of the area by daybreak Wednesday which combined with light winds and clear skies, is a favorable position for good radiational cooling. Given dewpoints falling into the 20s tonight, low temperatures will reach or fall below freezing across most of the area. Freeze watch has been upgraded to a warning for all zones away from the coast excluding Gulf and Franklin. Highs today will top out in the mid to upper 50s.
Lows tonight are expected to plummet into the mid to upper 20s in outlying areas of the wiregrass in southwest Georgia and adjacent southeast Alabama. Upper 20s to low 30s are expected through much of the Florida counties away from the coast and mid 30s around the coast. Widespread frost can be expected as well so allow a little extra time to warm up the vehicle and scrape any ice from your windows.
SHORT TERM
(Wednesday through Thursday night)
Issued at 420 AM EST Tue Nov 28 2023
Widespread frost and freezing to near-freezing temperatures early Wednesday morning give way to max afternoon readings in the mid/upper 50s despite plentiful sunshine. Strong surface high pressure maintains light northerly winds to reinforce the dry/chilly airmass before the boundary layer likely decouples once again late Wednesday/early Thursday. Another period of favorable radiational cooling conditions support a second round of frost/freeze conditions, albeit likely more isolated to scattered. Forecast low temperatures are in the low 30s away from the immediate coast with isolated upper 20s possible. The main wildcard will be cloud cover, which is probable via upper cirrus moving in from the west.
Depending on how blanketed the skies become, thermometers may read warmer than forecast. A warming trend then gets underway Thursday afternoon as the airmass begins moderating ahead of a developing area of low pressure off the TX coast. The short-term period closes out with highs in the 60s.
LONG TERM
(Friday through Monday)
Issued at 420 AM EST Tue Nov 28 2023
A shortwave trough racing northeastward off the Desert SW into the OH Valley late this week brings a frontal system and returning rain chances (thunder possible) our way on Friday. The front then stagnates across the northern Gulf coast this weekend as a broader upper trough amplifies over the Central US with a sharpening southwesterly jet streak along the Appalachians. These features will make for wet/unsettled weather through Monday afternoon characterized by multiple waves of rainfall, the potential for thunderstorms, and widespread cloud cover.
Severe weather potential is uncertain at this time, but flooding from repeated rounds of rain appear to be the greater weather concern. A pair of WPC Marginal Risks (level 1 of 4) are in place for much of the service area in the Day 4 & 5 Excessive Rainfall Outlooks - valid 12Z Friday to 12Z Sunday. Read the Hydrology section below for more details. Dry conditions arrive from west to east behind the departing systems near the end of the long-term period with a cooler airmass filtering in.
AVIATION
(12Z TAFS)

VFR through the period. High clouds currently will gradually thin out this morning and decrease in coverage this afternoon. Winds will be from the north to northwest at 5-10 knots with surface high pressure upstream moving into the southeast US.

Borderline advisory level conditions persist until around noon CST across waters west of Apalachicola while cautionary winds and seas continue over Apalachee Bay via brisk northerly winds. Surface high pressure moving in brings about lighter offshore breezes below headline criteria through mid-week before an approaching area of low pressure from the western Gulf brings about hazardous boating late Thursday and Friday. Chances for thunderstorms also return to the forecast heading into the weekend with a rainy pattern likely until Monday afternoon.
FIRE WEATHER
Issued at 420 AM EST Tue Nov 28 2023
Surface high pressure will continue its trek into the southeast US through Thursday. The coldest air of the season thus far will arrive during the next several days. Widespread freezes are likely both Wednesday and Thursday mornings. Afternoon humidity values will fall into the low 20 percent range in the wiregrass areas of southwest Georgia and along I75 Wednesday. Winds will be light given high pressure close by precluding any fire weather highlights at this time. Temperatures moderate into the weekend with wetting rains returning Friday into early next week.
HYDROLOGY
Issued at 420 AM EST Tue Nov 28 2023
Dry weather continues through Thursday, followed by a transition to a much wetter pattern heading into the weekend. Multiple rounds of rainfall (heavy at times) are expected between Friday and Monday.
The latest QPF amounts during that time frame are widespread 2-4 inches (isolated 5"+) - higher with northwestward extent. Values are subject to change in subsequent forecasts. Given the ongoing drought conditions, lack of rain since Sunday, and low river levels, there are no significant hydrological concerns. However, isolated flash or nuisance flooding is possible, especially in urban, low-lying, or poor-drainage areas.
