- Widespread cold air is expected this weekend.
- Freezing conditions may occur on multiple nights in the South into Monday.
- Astronomical spring begins Monday, and temperatures will start to feel like it.
Multiple mornings of freezing conditions could halt any greening plants just before we begin astronomical spring on Monday.
A late-season freeze is expected into Sunday morning across a large section of the South and additional freezes are possible into Monday morning.
A freeze warning means that temperatures below 32 degrees are expected within the next 24 hours and a freeze watch means that those conditions are possible within 48 hours.
Morning low temperatures in portions of the South, Midwest and East could not only kill plants, but could be cold enough to cause damage to outdoor pipes and cause minor health issues for anyone without access to heated structures.

Temperatures as low as the low 20s are possible into the Tennessee Valley and Ozarks. Lows in the 20s are possible down to the Interstate-20 corridor either Sunday or Monday morning, including Jackson, Mississippi, and Birmingham, Alabama.
These freezes are roughly 2-3 weeks later than the average last freeze for portions of the Lower Mississippi Valley, but are closer to average for much of the South.
The warmer-than-average winter for most of the South caused trees to bloom several weeks early across much of the region, so this may be a jolt to vegetation.
Temperatures will warm up quickly during the daytime hours, especially as we start spring and the new workweek.
Afternoon temperatures will gain 15-20 degrees from Sunday afternoon to Tuesday afternoon.
