Two separate weather systems will bring a plethora of weather types “with significant impacts possible” in northern Indiana, southern Lower Michigan and northwestern Ohio between tomorrow (Sat., Feb. 28) and Wednesday, according to an “Area Forecast Discussion” that the northern Indiana office of the National Weather Service (NWS) issued this morning.

Heavy snow, freezing rain, sleet, heavy rainfall and flooding all are possible.

NWS meteorologists expect the first weather system to bring all snow to the region late Saturday night through Sunday. That storm could bring two to four inches of snow over approximately the northern third of the northern Indiana office’s forecast area and three to six inches over the remainder of the region, according to an infographic the NWS issued this morning (below). The northern Indiana office had no immediate plans this morning to issue any advisories, watches or warnings associated with this first storm, “but certainly something will be needed eventually,” writes NWS meteorologist Sam Lashley.

Forecasters expect the second storm system to impact the region anytime from late Monday night through Tuesday night. This system could bring a mix of snow, sleet and freezing rain late Monday night and Tuesday morning, according to the “Hazardous Weather Outlook” that the NWS issued this morning. Meteorologists expect temperatures to rise above freezing Tuesday afternoon, when locally heavy rain could fall. Rivers and streams will likely still be frozen, so this heavy rain could lead to flooding of low-lying areas as well as ice jams and flooding along streams and creeks.

The track and timing of the second storm system remains uncertain, so the forecast might change. It would be wise to continue to monitor future forecasts.
