.SHORT TERM... (Sunday night through Monday night) Issued at 406am EST Sat Feb 15 2025

A cold front will be completing it's passage through the region by the start of this term. Surface high pressure will build behind it with northerly winds and zonal flow aloft. Much cooler temperatures can be expected, with morning lows in the mid 30s to low 40s. This, along with lighter winds will lead to the development of frost. Dry conditions are expected Monday afternoon with highs in the upper 50s to low 60s. Another chilly night in the mid to upper 30s is expected Monday night.

Long Term
(Tuesday through Friday) Issued at 406am EST Sat Feb 15 2025

The high pressure will hold until Wednesday when our next storm system approaches. During the day on Tuesday into Tuesday night, a shortwave trough will quickly develop over the Southern Plains as a surface low will develop over the Northern Gulf. The Low center will track along the coastal strip, bringing potentially heavy rain (around 2" with isolated higher amounts) across the region. The warm sector should remain just along the immediate coast if not offshore, keeping the severe threat limited. The Gulf low will continue eastward and move out into the Atlantic by Thursday, and an Arctic cold front will push through from the northwest, plummeting our temperatures and drying us out.

Before the Arctic front, afternoon temperatures can be expected to be in the mid to upper 60s with overnight lows in the upper 40s/low 50s. Following the front on Wednesday, afternoon temperatures will be in the upper 40s to low/mid-50s through the end of the term and overnight lows in the mid-30s, with the exception for Friday morning where temps will be in the mid to upper 20s and wind chills in the teens to low 20s. Keep checking the forecast, as these values may fluctuate.

Marine
Issued at 406am EST Sat Feb 15 2025

Cautionary conditions across our western waters for today with seas of 3-4 feet. This will deteoriate tomorrow (Sunday) as a cold front approaches. Wind gusts will increase to Gale force and seas of 6-8 feet. The cold front will also bring showers and thunderstorms, of which some may be severe with strong wind gusts and possible waterspouts. This will be a quick moving system arriving late Saturday night/early Sunday morning, and should exit the region by Sunday afternoon/evening. Behind the front, winds will quickly shift to be northwesterly and more northerly by Monday. Winds will still be elevated but should remain within Advisory levels through Monday morning. Winds and seas will begin to diminish on Monday afternoon and favorable boating conditions should return by Tuesday before our next system approaches on Wednesday.

Fire Weather
Issued at 406am EST Sat Feb 15 2025

Good dispersions are expected across the area given stiff southerly transport winds around 15 to 20 mph. A cold front will move through the area late tonight into Sunday with a line of strong to severe thunderstorms. Strong, erratic wind gusts and wetting rains are expected with the line. Transport winds on Sunday will become southwesterly to westerly around 20-30 mph, yielding good to excellent dispersions in the afternoon. Storms exit the area during the early afternoon with dry weather on Monday. Transport winds will be significantly lighter out of the north on Monday with fair to good dispersions anticipated. RH values will drop into the upper 20s to mid-30s Monday afternoon.

Hydrology
Issued at 406am EST Sat Feb 15 2025

Flooding may become a concern as a result of heavy rain next Wednesday. A swath of heavy rain is likely to develop north of a low pressure wave tracking eastward along the northern Gulf Coast. 1 to 2.5 inches of rain is currently forecast on Wednesday, with heaviest amounts from the FL Panhandle into South Georgia. These rainfall amounts would bring flooding to some urban and poor drainage areas, and they would bring rises on all area rivers, some to near bankfull. Ensemble river forecasts only point to about a 10 percent chance of rivers such as the Ochlockonee, Withlacoochee, Pea, and Shoal exceeding flood stage. Flooding would generally come with rainfall amounts at or more than 4 inches. There are a small number of ensemble members with rainfall amounts of 4-5 inches, and the deterministic GFS (Global Forecast System) has a stripe of 4+ inch rainfall across the FL Panhandle, but amounts of this caliber appear to be outliers at this point.

Otherwise, the 1 inch of rain that is forecast on Sunday will bring no flooding issues.

It will be interesting to watch water over the next few days as it routes down the Chattahoochee, Flint, and Apalachicola Rivers, following recent heavy rains near their north Georgia headwaters. The latest forecast for the Apalachicola at Blountstown brings it within a couple inches of flood stage starting Monday and remaining there for a few days.
