.NEAR TERM... (Today and tonight) Issued at 232 AM EDT Thu Sep 25 2025
The highly anticipated rainfall arrives today thanks to an approaching cold front moving across the MS Valley. The best rain chances are in the western to NW half of the Tri-State area. Environmental conditions are expected to be favorable for semi- organized convection capable of gusty winds, frequent lightning, and locally heavy downpours. An isolated damaging gust or two would not be surprising.
Prior to convective onset, patchy fog is slated to develop this morning. Models focus development from the Suwannee Valley to along/north of the I-10 corridor. Some of this activity may become dense. High temperatures are forecast to be in the low 90s.
For tonight into tomorrow morning, another wave of convection spreads from SW off the Gulf to NE, targeting the FL Panhandle coast into the Central Big Bend the most. This wet weather is likely to affect your Friday commute to work. Low temperatures range from upper 60s to low 70s under thick cloud cover.

.SHORT TERM... (Friday through Saturday night) Issued at 232 AM EDT Thu Sep 25 2025
Beneficial rains will affect a greater portion of the Tri-State area on Friday as the cold front responsible moves through the region. Frontal passage occurs some time on Saturday with drier NW winds in its wake reducing rain chances from west to east. Increased precipitation & cloud cover yields high temperatures in the 80s. Low temperatures are forecast to range from the mid 60s to around 70 degrees.
&&
.LONG TERM... (Sunday through Wednesday) Issued at 232 AM EDT Thu Sep 25 2025
Mostly dry weather appears to take place Sunday into early next week as upper troughing or cutoff low meanders over the region. Strong surface high pressure across the Mid-Atlantic states fosters a NE low-level, wedge-like-flow pattern. High temperatures are forecast to be in the upper 80s to low 90s while overnight lows in the 60s will be common.

.AVIATION... (12Z TAFS) Issued at 614 AM EDT Thu Sep 25 2025
Patchy early morning fog and low ceilings will result in some sporadic MVFR to IFR conditions early this morning, then becoming VFR by mid-morning. Showers and a few thunderstorms will encroach on the area from west to east through the day with the highest chance at seeing showers and thunderstorms at DHN and ECP. These will be sporadic through the period as opposed to an all day rain at any one terminal. MVFR to IFR conditions are expected with any showers and thunderstorms with VFR expected this afternoon outside of storms. Another round of showers and thunderstorms is expected early Friday morning for ECP, DHN, ABY, and TLH with MVFR to IFR ceilings also developing across the area.

.MARINE... Issued at 232 AM EDT Thu Sep 25 2025
Southwest winds prevail ahead and along of an approaching cold from the Mississippi Valley. Showers and thunderstorms return to the forecast today through Saturday. Maritime convection will be capable of locally gusty winds, higher seas, waterspouts, and frequent lightning. Westerly winds follow frontal passage this weekend, then turn more northeasterly next week. Favorable boating conditions are expected away from storms.
&&
.FIRE WEATHER... Issued at 232 AM EDT Thu Sep 25 2025
A cold front crossing the MS Valley brings showers and thunderstorms mainly NW of Tallahassee today. Some storms may be strong capable of gusty/erratic or isolated damaging winds, frequent lighting, and locally heavy downpours. High dispersions are forecast this afternoon across the I-75 corridor down to the Eastern FL Big Bend. Axis of rainfall overspreads much of the region on Friday with widespread wetting rains likely. Frontal passage occurs some time on Saturday, thus keeping rain chances confined east of Tallahassee. Prevailing southwest winds today-tomorrow turn more northwesterly behind the front on Saturday.
&&
.HYDROLOGY... Issued at 232 AM EDT Thu Sep 25 2025
Much needed rainfall is expected over the next couple days from an arriving cold front later today. Widespread amounts ranging from about a half inch to 1.5 inches are forecast with isolated 2+ inches beneath the strongest thunderstorms. Portions of the FL Panhandle, particularly around the Emerald Coast stand the best chance of experiencing the most rain through Saturday. Given the ongoing (flash) drought conditions areawide, flooding concerns are low. Flash Flood Guidance suggests that 4-6 inches of rain within 6 hrs would be needed. That said, local runoff issues are possible in urban, low-lying, or poor-drainage spots. We dry out again later this weekend into next week.
