It used to be that the Canadian global model had a lot of tropical cyclone candidates, sub-1000mb lows, during the warm season. I feel like they have changed a major component of that.
I really didn't know these severe days had this many reports. You might say that this is a lot of tornadoes on 3/15. A lot of (perhaps, brief,) QLCS tornadoes were added to the storm reports in the last couple of days

The storm is getting going with moderate snow in SD, MN, ND. It seems like snow-virga is in Wisconsin and Michigan. This view gives the warnings that are most current, so not all the blizzard warnings show up.
Texas?
Here's the NAM forecast for tornado parameter. There's going to be a high-shear environment for supercells near and south of the warm front, and possibly cold front. Models differ on how much the warm front moves toward the cold lakes (like me.)
