Missouri braces for another round of wintry precipitation

Accumulating snow, impacted roadways combine to create hazardous Wednesday commute

JEFFERSON CITY – Another round of wintery weather will move into the state overnight, bringing accumulating snow to roads that are expected to refreeze in bitterly cold temperatures. Snow is expected to move into the state in the early morning hours and continue throughout the day Wednesday. Snow totals of from 1 to 2 inches are forecast for the I-70 corridor with up to 5 inches possible along the I-44 corridor and the southern part of the state.

The Missouri Department of Transportation warns drivers to use caution on the Wednesday morning commute. If possible, stay off the roads until the snow has stopped falling.

Chemicals used to treat the roads lose their effectiveness in the bitterly cold temperatures that are expected to remain through Wednesday. Any thawing that occurs during daylight hours will likely refreeze overnight causing patches of black ice and slippery road conditions, particularly on elevated surfaces like bridges and overpasses. Please watch out for snowplows and give them plenty of room to work.

Additionally, rolling blackouts through western portions of the states will render traffic signals inoperative. Remember, when a traffic light is not functioning, the intersection is to be treated as a four-way stop with drivers alternating crossing.
