Southern US Braces for Late-Season Freeze and Hard Freeze Warnings.

Multiple mornings of freezing conditions are expected in the South into Monday, which could halt any greening plants just before astronomical spring begins 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. Temperatures as low as the low 20s are possible into the Tennessee Valley and Ozarks, and morning low temperatures in portions of the South, Midwest and East could cause damage to outdoor pipes and minor health issues for anyone without access to heated structures.
