Cold weather headlines will likely be posted in the coming days. && .DISCUSSION... (Through Wednesday) Issued at 1203 AM CST THU JAN 22 2026 Rain will continue with a stalled front over Central Alabama today into Friday, before finally pushing through toward the Gulf Coast during the day Friday. Some patchy fog is possible across the northwestern counties overnight into this morning if rain subsides. Models now indicate that an upper-level cutoff low meandering off the coast of California will open up into a trough by Saturday and eject ENE from Baja California to Texas by Sunday morning. A surface low is forecast to form in advance of the trough along the Texas coast and move NE into Alabama by Sunday. As of this forecast update, there is decent agreement in the modeling for the low to track very close to the Birmingham metro area, with a good warm sector south of the low across Central and South Alabama. Some data indicates temperatures Sunday morning into the afternoon may briefly reach the 60s and even low 70s across southern portions of Central Alabama and further southward. This is shown in the latest runs of several models, including the ECMWF, GFS, CMC, ICON, 12km NAM, and RRFS. A few of these models explicitly bring 60s to near or just south of the Birmingham metro Sunday morning, depending on the exact track of the low pressure center. Thunder has been introduced into the forecast Sunday morning and afternoon across the southern counties in Central Alabama. Although no definitive severe threat exists at this time, Sunday morning will bear watching as models indicate 500-700 J/kg SBCAPE and modest shear in the warm sector. Back to the north, our northern counties do remain under a Winter Storm Watch beginning Friday at 6 PM and currently in effect through 6 PM Sunday. Precipitation is likely to begin across the northwestern counties early Saturday morning. Models still indicate potential for this to be freezing rain or sleet. However, as several model runs have shown more of a warm nose across North Alabama ahead of the low, even the northwestern counties may warm above freezing Saturday night into Sunday morning, potentially becoming all rain with mid 30s. Slight fluctuations in the forecast from this point forward will mean differences in any ice accumulation vs. periods of rain. Highest ice potential is currently over Marion, Winston, and northern Lamar counties. The current forecast also shows the potential for cold air damming over Georgia to potentially affect northeastern Central Alabama. Warm air advection may at first have a tough time overcoming the wedge to the east. Thus, freezing rain and ice accumulation may be possible over counties such as Etowah, Cherokee, Cleburne, and northeastern Calhoun Saturday night into early Sunday before temps finally do rise above freezing. This is currently shown in the forecast, but any ice potential is highly dependent on surface temperatures. If we see temps tick up from the current forecast of 30-31 to 33-35, this will significantly reduce the chance of any ice accumulation. No changes will be made to the winter products at this time, but an expansion into Calhoun and Cleburne is not out of the question as the event gets closer. Now, as the low exits the area, taking the warm sector and any thunderstorms into Georgia, temperatures will drop aggressively Sunday afternoon and evening, beginning across the northwest. Any lingering precipitation will turn back into freezing rain and then potentially end as snow showers as the entire vertical column falls below freezing. The GFS is currently more robust with leftover moisture than the ECMWF, with more potential for additional wintry precip accumulation by Sunday evening. The official forecast does have the chance for additional ice accumulation Sunday afternoon and evening, with light snow amounts of a half inch or less across the northern/northwestern counties. All that is to say that we may be looking at drastically different weather conditions on Sunday across our forecast area from northwest to southeast. Everyone will finally get in on the cold Sunday night, with lows expected to drop into the teens across northern and central areas and 20s across the southeast. Northern areas may stay below freezing Monday before the entire area gets even colder Monday night, with area-wide teens likely and single digits possible north of I-20. A slow moderation of temperatures is expected into midweek. 12 && .AVIATION... (06Z TAFS) Issued at 1038 PM CST WED JAN 21 2026 MVFR conditions have begun in the north with periodic rains as a frontal boundary sinks into the region. Ceilings will lower after 3z. This activity will spread to AUO/MGM by 12-15Z. MVFR/IFR ceilings are likely to accompany this activity. Rain will likely persist through late in this TAF window as the front stalls across Central Alabama. There may be some clearing or less coverage after 2 to 3z in the north. 16 && .FIRE WEATHER... A wet pattern begins tonight and continues through the weekend. Wintry precipitation is expected this weekend for the northern parts of the area. Drier conditions expected early next week with min RHs back into the 30-40% range by Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
