M​ultiple mornings of freezing conditions could halt any greening plants just before we begin astronomical spring on Monday.

A​ late-season freeze is 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.

M​orning 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.

T​emperatures as low as the low 20s are possible into the Tennessee Valley and Ozarks.

T​hese 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.

T​emperatures will warm up quickly during the daytime hours, especially as we start spring and the new workweek.

A​fternoon temperatures will gain 15-20 degrees from Sunday afternoon to Tuesday afternoon.
