Des Moines, IA (northwestiowanow.com) — The lack of snow this winter is expected to change with plenty expected to fall this week. National Weather Service Meteorologist Dylan Dodson says 24 counties in northwest and north central Iowa are under a Winter Weather Advisory for later today into tonight.

Dodson says a second round of snow will hit mid-week and a Winter Storm Watch will go into effect. “Starting early Wednesday morning, late Tuesday night, early Wednesday morning, and then lasting through the day Wednesday. The greatest snowfall amounts will be over southwest Iowa with that one, but there will be snow over the entire almost the entire state,” he says.

Dodson says the week will end with more snow coming Friday for Valentine’s Day, and will continue into Saturday. He says it’s a little early to get an exact read on how much snow will fall at the end of the week.
