KSDK - Say good bye to our brief departure from winter.

The cold temperatures are back on Sunday with a 40-degree temperature drop, winds gusting to 35 miles per hour, sleet and snow!

A Winter Weather Advisory is in effect at 4 a.m. until 7 p.m. for areas south of Interstate 70 not including St. Louis City or County.

The precipitation arrived Sunday morning, starting with a little freezing rain but quickly changing to sleet . Cold, dry air aloft may help the St. Louis area as far as snow/sleet amounts. Around an inch on grassy areas is possible with as much as 2-4 inches south.

Wind chills will be in the teens.

Check for changes to the forecast all evening and overnight. Be sure to tune in to NewsChannel 5 at 5 p.m. for updates.
