Back in Arkansas, storm season use to be Feb to later April, now ur getting twisters in November. Had an F4 go through about 2mins from the house a few years ago, OK got a F5 last year or the year before during fall weather, not the typical storm season. Back in Idaho past 10 years the snow pack has gotten very scary "not enough snow pack"
This will be my first full winter in Colorado, and even this being October feels too warm, I think May was cooler than it is now here here in Monument vs current October. When the mountains are keeping snowpack and ur getting twisters in November, yes, Id be a littler worried myself too......
