Winter Returns this Weekend

Enjoy one more day with temperatures near average, cold air arrives tonight into Friday. Incoming high pressure late tonight will help to clear skies but it also brings a shot of colder air along with it. An upper level trough digs across the Great Lakes, and this will allow colder Canadian air into the Midwest and east.

The upper level pattern will also support a more active set up beginning this weekend. Light snow this morning is currently passing through southern Wisconsin with a mid-level
wave, but we are watching a few systems that have the potential for more accumulating snow.

The first arrives Friday night into Saturday, but the path of the low has shifted taking the strongest lift into southwest Iowa. This will take accumulating snow south and west of the Stateline, with just a dusting near the Quad Cities. The cloud cover will stick around this weekend, before our next chance for snow arrives Sunday night into Monday. Right now models are showing this low pressure track shifting more to the north and east compared to Friday's system. This will support more of a threat for accumulating snow to start next week. It is too soon to say what we will see in terms of snowfall, but we will keep you posted as we get closer.

Along with the scattered snow showers, we can expect high temperatures the next several days stuck about 10 degrees below average.
