Heaviest snow in Des Moines – from 5 PM to 10 PM Tuesday

Snow will be heaviest on Tuesday during the afternoon and early evening, potentially making a mess of the evening commute. Des Moines is expected to see around 4″ of snow, with 6″ possible along the Missouri border.

Winds will be strong during and after the snow, with wind gusts of 30 to 35 mph possible. In southern Iowa, this will make travel difficult through early Wednesday. Then, as temperatures drop, dangerous wind chills will be possible Wednesday as well.

Temperatures will remain cold through the rest of the week with highs only in the teens.
