It's been a cold start to the week for millions! Areas around the Great Lakes and Ohio River Valley took the most recent Arctic outbreak on the chin, with temperatures plummeting below zero in some instances. On Monday, as winds flipped out of the south, we began to thaw out and most of us are feeling either seasonable or above average by Wednesday. However...

More importantly, the temperatures swinging on the other side of it will send another chill down the spine of the Heartland. Wednesday night will be the rudest, while Thursday night will likely be the coldest, but should see the winds subsiding. Bismarck, the usual poster child for nasty cold, will only top out in the single digits Thursday afternoon and Grand Forks will be near 20 below Friday AM.

Like a trampoline, temperatures rebound the following day for most.
