Old Man Winter is just not letting go. Just as people in the Plains and Midwest were thinking winter was over, another blast of snow is in the forecast this week. Rounds of rain will start to fall over portions of the Midwest Wednesday including the state of Michigan. The bad weather will continue on right through Friday with snow, freezing rain, sleep and possibly hail. What’s causing this bad weather is a frontal boundary that is separating moist & mild air from the Gulf from a chilly area of low pressure across Northern Canada. That boundary line is right across Iowa, Illinois, Indiana and Ohio. Temperatures are in the 60s and 70s west of the line and in the 30s and 40s east. The northern portion of Michigan will be on the coldest side of the front with a frigid northeast wind.
The rest of the week is looking to be a messy one in the Midwest. The cold winds coming out of Canada will cool down the atmosphere over the Midwest even more to make conditions perfect for rain, freezing rain, sleet and in some cases, all snow. In Northern Iowa, a winter storm warning went into effect at 1AM Wednesday. Rain in the northern portion of that state is expected to be mixed with freezing rain and snow. Ice could accumulate on things at half-inch thickness followed by several inches of snow. Those types of weather conditions will make travel hazardous across Iowa.
The state of Minnesota averages just over 2 inches of snow for the month of April. That average will be surpassed this week in the state as snow will pile up in several Minnesota cities including the Twin Cities of Minneapolis and St. Paul. Some towns could get well over one foot of wet, heavy, sloppy snow. As the storm system tracks eastward, Wisconsin is also going to see some snow, freezing rain, sleet and possibly hail. A flood watch is in effect for southeastern Wisconsin through Friday as up to 3 inches of rain or wet snow is expected Wednesday. Communities like Chicago and Milwaukee will see challenges with wet basements and some minor flooding, but could dodge a major flood burden due to the lack of snow melt this spring. On Thursday and going into Friday, snow is expected to fall over the Badger State with some areas possibly getting 2 to 3 inches.
