Extreme cold, freezing rain, snow, ice and high winds make for a potentially dangerous storm system expected Saturday night into Sunday.

The National Weather service Winter Storm Watch is in effect from Saturday at 6 p.m. through Sunday at 6 p.m. — as of Friday at 6:10 p.m. Three to six inches of snow with  higher amounts locally is expected. Travel could become difficult especially on untreated roads. 

The Missouri Department of Transportation issued a “no travel advisory” for the duration of this storm, which is expected to continue through part of the day on Sunday, March 3.

This storm system is tracking from the west to the east and will bring bitter cold temperatures and snow accumulations of up to six inches throughout much of the state, according to the National Weather Service. Sleet and freezing rain will also be possible. Blowing snow will also reduce visibilities at times on Sunday. Snow accumulation could reach an inch per hour.

Becky Allmeroth, MoDOT State Maintenance Engineer and Chief Safety and Operations Officer said,“We advise everyone to stay off the roads. At times, snow will be heavy. For your safety please stay home.”

Road treatment chemicals are affected by the extreme cold, according to MoDOT. At 30 degrees, one pound of salt will melt 46.3 pounds of ice, but at 0 degrees, the same pound of salt will melt just 3.7 pounds of ice. 

When temperatures drop below freezing, MoDOT often adds other products such as calcium chloride and beet juice to the salt to help it work more effectively. For road conditions including winter weather conditions and traffic speeds, please check MoDOT’s Traveler Information Map at traveler.modot.org
