The infographic above shows the thinking of the northern Indiana office of the National Weather Service (NWS) as of midday Friday, Nov. 15, regarding the threats for severe weather Sunday. The information applies to all 37 Indiana, Michigan and Ohio counties covered by the northern Indiana office.

First severe storms could be seen as early as 10 am.
Severe threat will diminish after 8pm once the cold front moves through.

A line of thunderstorms will form along the cold front with a high risk for damaging winds
Tornadic circulations are possible along this line. There is a slight risk for low-topped supercell development ahead of this line with a risk of damaging winds and tornadoes

While there is still some uncertainty regarding the extent of the severe weather potential in our forecast area, there is increasing confidence that portions of the forecast area will see severe weather on Sunday. The tornadic threat is still quite uncertain, although there is at least a slight chance for a significant tornadic event.
