A strong low pressure system is forecast to impact the Upper Mississippi River Valley and the Great Lakes beginning Wednesday, and possibly lingering into Friday. In general, the surface low is expected to track from eastern Colorado and Nebraska to southeast Ontario. The low will be interacting with an unseasonably moist air mass that will be surging north from the central Plains. The result should be the potential for heavy rainfall across the region.
Here in the Northland, it appears as though the rain will come in two main waves: the first moving through Tonight and early Thursday morning, followed by a relative lull with lighter rain most of Thursday Morning, and more rain from Thursday Afternoon into Friday Morning.
