ST. LOUIS (KSDK) - A Winter Storm Warning is in effect for most of the NewsChannel 5 viewing area for Thursday.

A mixture of snow sleet and freezing rain has moved into the NewsChannel 5 viewing area, and several highways were closed briefly due to accidents.

This winter mix will last until early evening, then spread east across central Illinois.

From midday Thursday through late afternoon areas north of I-70 and west of St. Louis could see 5-7" of mostly snow and some sleet.  In the metro north and west of the I-44 corridor 3-5" of snow and sleet are possible; south and east of the I-44 corridor in the metro 1-3" of snow and sleet are possible.

Areas south and east of the metro may see some snow and sleet but are more likely to see freezing rain, perhaps as much as a quarter of an inch.

During the evening some freezing rain may work its way into the mid-metro region before the storm lifts out of the area entirely after midnight.

Precipitation will fall fast, and because the ground is so cold, stick quickly so surfaces conditions may deteriorate rapidly.

The National Severe Storms Laboratory is looking for the public to submit observations of the upcoming storm.  Doing so will give them the ability to compare radar images to actual precipitation, helping improve weather technologies.  You can submit your precipitation photos to the PING Project online.

The Missouri Department of Transportation put workers on a 12 hour rotation. Some crews headed home at 12 p.m. Wednesday and returned at 12 a.m. Thursday morning to continue road treatment.

The goal was to pre-treat 11,000 miles of roads by Thursday morning, focusing most on bridges, overpasses, and known slick spots.

Mayor Francis Slay says the city is prepared for the worst, but hoping for the best.

Because temperatures are below freezing, crews also used a beet juice mix, which makes the normal salt brine a bit more effective.
