Rough roads through Monday afternoon
A low pressure system is located over the Nebraska/Kansas border - it's warm front is stretched out across Iowa and Missouri - and is causing our driving conditions to rapidly deteriorate. This system will move across Iowa tonight and cross the lower peninsula Monday. Behind it is a second low pressure that will pass north of the Great Lakes Tuesday, bringing an end to very mild weather as we get into the mid-week.
For tonight through Monday morning - if you do not have to be on the roads, stay at home! We have heavy snowfall moving through right now, and as the warm front ushers in more warm air, we'll see a switch-over to sleet and freezing rain, before finally turning to rain later Monday.
