Daytime highs above freezing are expected by this weekend, but overnight lows will continue dropping back down below freezing.

This could cause better driving conditions during the day, but a re-freeze after dark.

“Another one that everyone needs to be aware of too is things have been so cold for so long, we have ground temperatures pushing near 0 degrees…which is the coldest they’ve been and that’s not going to warm up very quick.”

Maintenance engineer Jason Shafer with MoDOT tells KRMS News the cold temperatures have made it difficult to keep the roads clear.

“The salt we use on the roadway drops off on it’s effectiveness when we get below 25 degrees, and we’ve been down below zero. So at those temperatures, we’ve really only been able to plow and put down abrasives.”

Shafer says even when daytime temperatures do get above freezing, it’ll still take a few days for the ground to thaw out.

Ice can now be seen across much of the main channel of the lake and weather forecasters say it is too thin to walk on.
