NEAR TERM

(Today) Issued at 327 AM CST Tue Dec 30 2025

Cold high pressure centered over Texas was controlling the general weather situation across the Tennessee Valley. Most temperatures have fallen into the mid and upper 20s. An area of stratus that formed south of the Great Lakes on Monday moved southward during the course of yesterday evening, and was now blanketing much of the forecast area. It was breaking up over NW Alabama, but was still in place over parts of our central and eastern areas. These clouds have helped to keep conditions "warmer" than forecast so far. But with clearing over our western areas, temperatures have fallen into the mid 20s at locations like Muscle Shoals and 23 in Iuka. Regardless, cold conditions will continue and become colder under places the clouds dissipate.

These clouds could play a role with high temperatures later today. Where they fade, highs should rise into the upper 30s. Places under those clouds should they hold on longer, highs may struggle into the mid 30s. Short term model output has the stratus dissipating late this morning. Northwest winds of 5-15 mph this morning, should subside to 5-10 mph in the afternoon.

SHORT TERM

(Tuesday night through Thursday) Issued at 957 PM CST Mon Dec 29 2025

Latest short range model consensus indicates that dry northwest flow aloft will continue across the local forecast area through the duration of the short term period. At the surface, a ridge axis extending northeastward off a weakening arctic high across south TX will nose into the region from the southwest tomorrow evening, providing a period of light/variable-calm winds and an environment favorable for radiational cooling. However, with high- level clouds (related to a clipper system to our north) expected to increase in coverage as early as late tomorrow afternoon, overnight lows may be a couple of degrees warmer (compared to tonight) on Wednesday morning. As the remnant low-level anticyclone across south TX spreads southeastward across the Gulf from Wednesday into Thursday, light-moderate WSW flow will result in a modest warming trend to the south of a reinforcing cold front (that will stall across TN on Thursday). Highs will return to the u40s-l50s on Wednesday and l-m 50s on Thursday, as lows rise back into the m20s-l30s.

LONG TERM

(Thursday night through Monday) Issued at 957 PM CST Mon Dec 29 2025

Our next weather maker is set to move in on Friday as a shortwave digs into the Deep South and sfc low pressure tracks across northern Alabama. Southwest winds will keep temps on the warm side Thursday night into Friday as increasing tropical moisture brings overcast skies to the area by Friday morning. Right now there is fairly decent agreement among models that the sfc low will track either over north AL or just to our south, keeping us outside of the risk for any severe weather but right along the axis of heavier rainfall where some locations may receive up to 1". Localized flooding concerns remain very low especially considering the area is listed as either abnormally dry or in a moderate drought per the U.S. Drought Monitor. Enough elevated instability may be present to support a few thunderstorms Friday night as the heaviest activity moves through but this should all come to an end by Saturday afternoon. A weak cold front will move through on Saturday but we will see little change in temperatures as the upper ridge to our west remains the dominant influence on our weather locally. After this, dry conditions are forecast beginning Sunday with warmer highs in the upper 50s/lower 60s and lows near 40 degrees as we head into the work week.

AVIATION

(06Z TAFS) Issued at 1140 PM CST Mon Dec 29 2025

A northwest wind of 8G16 kts will continue at the terminals during the early morning hours, as a postfrontal cold air stratus layer spreads southeastward, providing intermittent periods of low-VFR to high-MVFR cigs (2500-3500 ft). These conds will persist through 15Z, before skies clear and winds strengthen to 10G20 kts. Sfc winds will subside and back to WNW late tomorrow aftn (before becoming lgt/vrbl during the evening hours), with an increasing coverage of high-lvl Cs anticipated as well.
