Temperatures around 20 below and sustained northwest winds at 10+ mph led to some impressive wind chills over the past past 24 hours (Saturday evening into Sunday morning) across central and northeast South Dakota and west central Minnesota. The good news, in most cases, is the timing - temperatures moderated quickly once clouds moved overhead by sunrise.

 

 

Although arctic air to around 20 below zero will once again be present Monday morning, especially in eastern South Dakota, the high pressure system will be overhead meaning much less winds in most cases. Counties under a Wind Chill Advisory (in light blue) for tonight through Monday morning are shown below. These areas could see wind chills around -25 to -34. Frostbite will still be possible in as little as 30 minutes to exposed skin.
