The National Weather Service is calling for a 100 percent chance of 3 to 6 inches of snow within the next two days in the St. Louis area. Two to 4 inches of snow accumulation is expected to fall beginning around 4 p.m. tonight, with a 70 percent chance of more precipitation tomorrow morning.

Kara Price, a spokeswoman with the Missouri Department of Transportation (MODoT), said that MoDOT is pretreating heavily traveled roads with a salt and beet juice mixture. Beet juice makes the salt more effective, fighting through icier patches. MoDOT has around 32,000 tons of the salt mixture ready at the beginning of winter, and it has about 22,000 tons left, which is plenty for this time of year, Price said.

“We are prepared with 220 trucks and 400 employees, ready to work in 12-hour shifts, around the clock,” Price said. “We pretreat and then plow the roads until they are mostly clear to make them safe for motorists.”

Price strongly encourages motorists to get home from work early today.

The Missouri State Highway Patrol is encouraging motorists to plan ahead and drive safely, or not at all, during inclement weather. If you must drive, plan extra time into your schedule to clean snow and ice completely from your vehicle.

Looking ahead, there is a chance of sleet and snow on Friday night, with a chance for more snow on Saturday and Sunday. 

Price said that MoDOT primarily consults the same weather sources that are available to the general public and always makes sure it has its crews ready.

“We have good organization of our plan and how we use our crews. It’s kind of  a 24-hour-a-day job, no matter if it’s in the light or the dark,” Price said.
