Air temperatures fell near -20 degrees across the Chippewa Valley early Friday morning. Even the slightest wind speeds could produce wind chills near -30 degrees, which pushes frostbite times under 20 minutes.
The region of cold, arctic high pressure will continue to shift eastward Friday which will bring back the sunshine and help the warmer air to our southwest inch closer.
We'll see high temperatures climb into the mid teens (above zero) but the southerly breeze at 5 to 15 mph will produce wind chills near 0 still. It's the warm front that moves in overnight Friday that will swing temperatures roughly 50 degrees with highs in the low 30's Saturday.
This front may also drop a few light flurries across the valley Saturday, but no accumulation is expected. At best, areas north may see a light dusting.
Below average temperatures return for Sunday before a system aims to bring multiple inches of snowfall Monday. It looks like Monday's system will be enough to produce light to moderate snowfall at times that could lead to some travel impacts.
Stay tuned over the weekend as this system develops and check back often. The Stormtracker 18 Weather Team will continue to monitor this developing system.
