KEY MESSAGES

Updated at 1118 AM CST Tue Dec 23 2025

- Warm temperatures are forecast through Sunday with highs in the 60s and 70s.

NEAR TERM

(Rest of Today and Tonight) Issued at 140 PM CST Tue Dec 23 2025

There have been no significant changes to near term forecast reasoning since the update earlier this morning. Although current visible satellite data suggests that some temporary breaks are occurring in the overcast stratus layer, this should not be the prevailing condition, and for this reason we have not made any adjustments to the max temperature forecast. Overnight lows still appear to be on track to only fall into the m-u 50s (with lower 50s possible in far northeast AL).

Previous Discussion: In the mid/upper-levels, the local forecast area will remain under the influence of a strong subtropical high (centered across the Gulf) for the duration of the near term period. As a ridge builds into the northwestern Gulf Coast, NW flow aloft will remain in the 30-40 knot range. In the lower- levels, a surface high (initially positioned across GA) is predicted to gradually weaken and shift southwestward into the western FL Panhandle by this afternoon, before becoming established across southern portions of MS/AL tonight. With this configuration providing a favorable veering and strengthening wind profile with height (in the presence of sufficient moisture advection), we expect low stratus clouds and spotty light rain showers/sprinkles to persist for much of the day and into tonight. Thus, we have made a minor increase in POPs to indicate rain chances in the 5-15% range (with highest values north of the TN River, where a weakening cold front sliding southeastward into the OH Valley this afternoon and to the KY-TN border overnight may provide additional low-level lift). Current surface observations suggest that high temperatures are on track to reach the 65-70F range for the majority of valley locations today (lower 60s in elevated terrain). Overnight lows will be mild and in the m-u 50s (lower 50s in our southeastern zones).

SHORT TERM

(Wednesday through Thursday night) Issued at 1118 AM CST Tue Dec 23 2025

Little change in the general synoptic environment is anticipated tomorrow, with light west-southwesterly in the low-levels maintaining a warm/moist airmass across the region. Due to the existence of at least weak lift within the deep-layer warm/moist advection regime (discussed above), we will also maintain a 5-15% POP region-wide for sporadic light rain showers/sprinkles through 0Z Thursday.

Beginning Wednesday night, chances for light precipitation will likely become more focused to the north/east of the region and in the vicinity of a weak surface low that will travel eastward from eastern KS/western MO (Wednesday afternoon) into the central Appalachians (Thursday morning). This regime will be reinforced on Thursday and Thursday night as a stronger cyclone evolves out of a lee trough across the central High Plains and migrates eastward into the Mid-MS Valley. Although low rain chances across our region will diminish as this occurs, an even thicker layer of low stratus clouds is predicted to blanket the TN Valley from Wednesday night-Thursday night, with a modest increase in southwesterly flow and dewpoints rising into the m-u 50s supporting warm temperatures. Highs both Wednesday and Thursday will be in the l-m 70s, with overnight lows in the m-u 50s (lower 50s in our southeastern zones).

LONG TERM

(Friday through Monday) Issued at 1048 PM CST Mon Dec 22 2025

The forecast remains warm and dry through the first half of the weekend before a cold front brings low to medium rain chances and much colder temperatures to the area Sunday into Monday. Highs will remain in the 70s through Saturday with lows in the 50s and even lower 60s Friday night into Saturday morning. Rain chances will begin to increase from north to south Sunday morning as the cold front moves through the area. Highs will reach the 60s Sunday afternoon before temps plummet down into the 20s by Monday morning. Next week looks to be much colder with highs in the 30s early in the work week. So if you like warmer weather, enjoy it while it lasts!

AVIATION

(18Z TAFS) Issued at 1148 AM CST Tue Dec 23 2025

Moist southwesterly flow in the low-levels will persist across northern AL for the duration of the valid TAF period, maintaining a bkn-ovc layer of low stratus clouds. Although this cloud deck will provide MVFR cigs for much of the period, a brief opportunity for lifting/scattering of the stratus layer may occur from late this afternoon into the early part of the evening. Spotty light rain showers or sprinkles may also periodically impact each terminal, but due to low confidence in coverage we will not mention this in the TAFs attm. Sfc winds will remain from the SW- WSW with prevailing speeds of 5-10 kts (and gusts up to 16 kts this aftn).
