St. Louis region experiences sharp temperature drop and freeze warning

Residents in the St. Louis area experienced a significant temperature decline, with overnight lows falling into the upper 20s and low 30s. This sudden shift triggered a Freeze Warning that remained in effect through 8 a.m. on Saturday morning.

The cold snap was accompanied by patchy fog, which was expected to lift as temperatures rose toward midday. The rapid transition from milder conditions on Friday to freezing temperatures on Saturday presented immediate risks to local gardening, particularly for perennials, vegetables, and container plants.

Forecasters projected a gradual warmup over the following days, with daytime highs expected to rise steadily and reduce the immediate risk of additional frost.
