Nothing strange about a tornado in February in Wisconsin rule

Weather is getting weird af where I live. This winter the snow only settled mid december, which is kinda scary, because it was supposed to do so 1-2 months before. After that temperatures are mostly the usual -15°C to -25°C, but occasionally there are 2-3 days where it is up to +5°C and super windy and then it comes back to normal, except everything becomes covered in a thick layer of super smooth ice, it sucks.
