Temperatures should plunge to -20 or colder in the far north Tuesday morning. Twin Cities' residents will have to settle for -7 or so. That would be the coldest temperature so far this winter season. We hit -5 earlier in December. This is good news if you're waiting for the ice to thicken up on your favorite lake. Only a Minnesotan (and other residents of the Upper Midwest) would see that as a silver lining.
Wind chill advisories are posted for nearly all of Minnesota until 11am Tuesday.
There some good news if you'd like it a bit milder. Temperatures should return to near average levels Wednesday as southerly winds return.
