| Area Forecast Discussion National Weather Service Tallahassee FL 1023am EST Sunday Jan 18 2026 ...New .KEY MESSAGES... Issued at 1018am EST Sunday Jan 18 2026 - Hazardous marine conditions are expected today as strong northerly winds will take hold behind a strong cold frontal passage. A Gale Warning is now in effect through early afternoon for the Gulf waters. - A freeze is expected over inland areas on Monday morning. Issued at 1018am EST Sunday Jan 18 2026 The cold front moving across the southeast today is quickly moving across our counties this morning. This has lead to updating the weather and Probability of Precipitation forecast to represent a more rapid clearing behind the front. Counties will continue to fall off the Winter Storm Warning/Winter Weather Advisory as the cold front exits the region. Otherwise, no other changes appear necessary, behind the front the sun is already beginning to shine across parts of SE Alabama and the FL Panhandle. Any snow accumulation from this morning is expected to quickly melt heading into this afternoon. .SHORT TERM... (Today and Tonight) Issued at 215am EST Sunday Jan 18 2026 The main winter weather event will commence during the upcoming pre-dawn hours. Forecast snowfall amounts have increased into the 1-2 inch range from near the FL/AL state line across southeast Alabama on over to near and north of Albany. This triggered the recent upgrade over these areas to a Winter Storm Warning. Cold air (sufficiently cold for snow) will spread past the I-65 corridor south of Montgomery in the next few hours. After that, it will start to interact with the precipitation shield across southeast Alabama, bringing a changeover from rain to snow. IR satellite imagery shows cloud tops have been cooling across SE MS and SW AL, aided by deep lift in the right entrance region of a powerful 300 mb jet streak translating up the U.S. Eastern Seaboard. The cloud tops will be a nowcasting aspect early this morning, since the coldest cloud tops will coincide with where the deepest lift and moisture can produce snowflake growth in the colder, higher parts of the atmosphere. Guidance since Saturday afternoon has been trending further west with wintry precip, and our Winter Weather Advisory has been expanding further west across the Alabama Wiregrass and inland FL Panhandle. There is consensus among our newest guidance favoring an axis of heavier 1-2 inch snowfall amounts from near Dothan northeast to near Dawson and Leesburg GA, including Albany. Given the evaporative cooling as the incoming dry air mixes in with the precip, it is not surprising to see more and more members of our CAMS guidance showing air temperatures of 30-32 degrees within the heaviest precipitation as it crosses this area. Nudging temperatures down to even a little below freezing increases accumulation potential. Some of our forecasting tools also increased snow ratios in the warning area from 7:1 up to 10:1. When also factoring in an increase in Quantitative Precipitation Forecast over the warning area, it all points to more potential to exceed 1 inch of accumulation, with pockets of 2-3 inch snowfall. Within the warning area, snowfall rates suggest slushy accumulation on roadways. In shaded areas, some re-freeze is possible tonight. Have also expanded the Winter Weather Advisory to include more territory in the FL Panhandle. In the advisory areas, accumulations less than one inch will prevail. Air temperatures will generally be a little above freezing as it snows as well. Light accumulations will mainly be confined to grassy surfaces. The eastern extent of the existing advisory still looks good, considering guidance has been trending west. No changes on the eastern extent. Precipitation will end abrupartly around midday, as the all- important upper dynamics and lift quickly exits off to the Carolinas and beyond. A cold and dry air mass will overspread the whole region this afternoon. Nonetheless, full sunshine and temperatures in the 40s this afternoon should melt off most of the snow that accumulates. In the warning area, shady spots may hang on to some snow. Widespread freezing temperatures are forecast late tonight and Monday morning. Lows of 24-29 will be most common. Have opted for now to not issue a (Hard) Freeze Warning for tonight (criteria 25 degrees or less). Despite a few places over AL/GA with lows 23-25, it is not widespread, and HREF shows only low chance odds of temperatures below 25 degrees centered over the Flint Valley on Monday morning. The upcoming day shift will have one more opportunity to assess. Long Term (Monday through Saturday) Issued at 215am EST Sunday Jan 18 2026 Low impact weather is forecast from Monday through Saturday. A cold and dry air mass will persist through Tuesday night, thanks partly to a reinforcing cold front early Tuesday. Low-level flow will clock around to a milder easterly direction on Wednesday, as surface high pressure moves off the NC coast. A weak shortwave with the broadly cyclonic jet stream flow could stir up a few showers around Thursday. A stronger cold front will approach from the northwest next Saturday, bringing yet another chance of rain. Marine Issued at 215am EST Sunday Jan 18 2026 We have upgraded the Small Craft Advisory over the Gulf waters to a Gale Warning. Guidance has increase on northerly wind speeds this morning behind the incoming front, with gusts near 40 knots now expected. From CWF synopsis... A surge of gale-force northerlies will travel southeast across the Gulf waters this morning, following passage of a strong cold front. Northerlies will then decrease from this afternoon through late Monday, as a high pressure ridge expands out across the northern Gulf Coast. A reinforcing cold front Monday night will restrengthen the northerlies. High pressure moving off the North Carolina coast will cause winds to clock around easterly on Wednesday. Another high will pass by to the north late Thursday and Friday, bringing an increase in northeast breezes. Fire Weather Issued at 215am EST Sunday Jan 18 2026 A cold front will sweep across the region this morning. It will be accompanied by rain. The arrival of cold air right behind the front will bring a changeover to snow for southeast Alabama, southwest Georgia, and the eastern Florida Panhandle before precipitation ends. Gusty north winds will pick up this afternoon. Widespread freezing temperatures are expected early Monday morning. A cold and dry air mass will then persist across the region on Monday and Tuesday. The air mass will start to moderate and moisten some on Wednesday. Hydrology Issued at 215am EST Sunday Jan 18 2026 No flooding is expected for at least the next 7 days.
