A strong, Arctic cold front will arrive after midnight tonight providing enough lift for some light snowfall. The light snow will begin around 5am Thursday, continuing through noon. It should be a fluffy snow but with temperatures in the high single digits, road chemicals will not work properly so plan for some very slippery roads. On top of that, a gusty northwest wind will cause some blowing and drifting…not to mention dangerously cold temperatures. Wind chill values could hover around -15 in the afternoon hours of Thursday.
A very strong clipper system will arrive Friday, spreading snow across the region in the morning hours. This should produce a steady snow through Friday evening. This is just an estimate of potential snow. Don’t get too caught up on Freeport’s 7.3 because Lake Geneva has only 3.4. This map isn’t a final, rather just one model’s solution for the storm. In fact, there are models that put down up to 10 inches across Northern Illinois and Southern Wisconsin and a few with as little as 4″. It certainly seems logical that we can say “Winter Storm Possible” at this point. Be ready for Friday! -ES
