We’re making ice this week on Minnesota’s lakes. Our sub-freezing week peaks Thursday and Friday with low temperatures near zero across most of Minnesota Friday morning. But ice cover remains sketchy on Minnesota lakes.
Case in point? Douglas County Minnesota.
A reminder that ice varies widely in quality. This ATV and fish house went through this weekend in Douglas Co. in a spot where the ice went from 8 inches to a half-inch. Luckily, nobody was hurt. Check ice thickness at least every 150 feet as you head out. https://t.co/ptZ9l1YNOX pic.twitter.com/N96WVoMb6V

Ice thickness varies
Big differences in ice thickness occur over short distances. Some spots may show several inches several inches of ice. Just a few feet away the ice could be newly formed and very thin. Natural springs or flowing water through channels also reduces ice thickness. Here’s the rough guide for “safe ice.”
The best advice? Know your lake. And check ice thickness frequently. Ice thickness seems static, but it often changes through the winter season.
Arctic front arrives Wednesday night
Thursday’s inbound air mass looks respectably cold.
Temperatures Friday morning bottom out a few degrees either side of the zero-mark across Minnesota. Friday will likely be the coldest morning so far this season for many locations in the Upper Midwest.
December thaw next week?
I’m still tracking a major shift in the upper air pattern next week. If it pans out, temperatures will run well above average. We could see an extended thaw next week.
Climate change: The world’s biggest opportunity?
Many of us who see the growing set of problems from climate change also see opportunity. I’ve called the technological boom from climate solutions our next great economic moon shot. Here’s more perspective on why we should look at climate change as a hopeful opportunity.
