While the morning commute looks to be problem free, the afternoon and evening rush hour may be another story.

The National Weather Service (NWS) has issued a winter weather advisory for the St. Louis area, including St. Peters, that is in effect Monday from 9 a.m. until midnight. NWS experts are forecasting accumulations between 2 and 4 inches for the metro area.

The snow will begin in the mid-morning hours and continue throughout much of the day, according the the NWS. The heaviest snow will fall during the afternoon and early evening hours.

Kara Price, a spokesperson for the Missouri Department of Transportation (MoDOT), said workers have been pretreating the roads since Saturday night in anticipation of the storm.

"We'll have full crews coming in overnight and throughout the day since it's supposed to be an all-day storm," she said. "We most concerned about the evening rush, so we'll be hitting the roads with extra salt before then."
