Area school districts canceled classes for a second-straight day Friday as overnight temperatures plunged near zero after the latest winter storm left many neighborhoods with sleet-covered streets.

This week's storm started Tuesday with some freezing rain and drizzle and continued largely unbroken until Wednesday night, when it turned into sleet. The National Weather Service issued an ice storm warning Wednesday afternoon.

People up late Wednesday might have witnessed lighting and thunder among the freezing precipitation, and in Clinton, Mo., some hail fell. By Thursday morning, the metro area saw icy accumulations of about a quarter-inch to a half-inch.

Public works crews had main roads and highways mostly cleared and just wet on Thursday, but many side streets remained at least partially covered, and with frigid temperatures rolling in it led to refreezing on many roads.

Metropolitan Community College campuses delayed the start of classes Friday until noon, as sub-zero wind chill values were predicted for the metro area into Friday morning. The Palmer Senior Center Independence also is closed Friday.

The Weather Service predicted sunny skies with high temperatures about 20 degrees Friday, with some clouds Saturday but high temperatures in the low 30s. Sunday brings a chance of wintry precipitation – small accumulations if any – with highs into the upper 30s.
