UNITED STATES — After a stretch of unseasonably warm temperatures across the southern United States, new forecast guidance is hinting that colder air could quickly sweep in behind a late-week system, bringing the possibility of a morning freeze threat around February 23–24.
Model data valid for the morning of Tuesday, February 24, shows temperatures potentially dipping into the mid-20s to lower 30s across portions of Arkansas, northern Mississippi, northern Alabama, and Tennessee. While this does not appear to be a full-scale polar outbreak, it could be enough to produce patchy frost and light freeze conditions in some areas.
Where the Coldest Air Could Settle
The projected temperature map highlights:
- Mid-20s across northern Tennessee
- Upper 20s across northern Mississippi and northern Alabama
- Upper 20s to near 30 across parts of Arkansas
- Low 30s stretching southward toward central Alabama and Georgia
Farther south, along the Gulf Coast, readings are expected to remain milder, generally in the mid-30s to low 40s.
The setup suggests a quick push of cooler, drier air rather than a prolonged winter pattern.
Why the Timing Matters
The potential freeze risk follows a period of warmer-than-average weather expected earlier in the week. Rapid temperature swings during late February can be impactful, especially for:
- Early budding plants
- Outdoor agriculture
- Sensitive landscaping
Even a brief drop below freezing during early morning hours can cause localized damage if vegetation has already responded to spring-like warmth.
Not a Polar Plunge — But Worth Watching
Forecasters emphasize this does not resemble a major Arctic blast. Instead, it appears to be a quick surge of colder air behind a departing system…
