Snow in Colorado
Denver had a new all-time September record high temp on Saturday, when they hit 101. They had highs in the 90s on Sunday and Monday. They’ve been in the 30s most of today, and Denver is expecting 4 to 5 inches of snow Tuesday night:

Temperature trends

Our temps will gradually rebound. Twin Cities metro area highs are projected to be in the lower 60s on Thursday, followed by mid-60s Friday. We could top out in the upper 60s on Saturday and around 70 this coming Sunday. 70 degrees will feel great!
