Winthrop is basically to cold what Redding is to heat. It’s like every possible geographical factor comes together to make that place as cold as possible in the winter. Kelowna is 100 miles farther north and only a couple hundred feet lower, yet its winters are like 5°F warmer on average.
12/1/21 was so bizarre. Nothing close to it had ever happened before, and then this weird cracky setup just popped up and destroyed the all time monthly record high by 16°F. Winthrop has never observed a warmer temp than 12/1/21 between Halloween and mid-March.
