Well here in Montana it has sure been a strange one. Last Saturday it was 58 degrees at 5pm and by 7pm it was 15degrees. Had massive snow melt on frozen ground and then it froze like a skating rink. Sunday morning was -5. It’s forecast to be -5 to -10 today with wind chills at -35. We don’t call it a vortex, just winter in Montana, lol. But for the most part it has been super mild this year.
