It's another cold morning in northern Illinois and southern Wisconsin. Cloud cover from Wednesday evening cleared out just enough to allow temperatures to fall into the low single digits. Winds have been fairly gusty from the north/northwest this morning dropping wind chills as low as -18°. Winds will lighten up some during the afternoon but the increasing cloud cover will halt temperatures from rising much past the mid and upper teens today.
A fast moving storm system will move in late tonight and early Friday morning. Moisture will remain limited, however, with such a dry and cold atmosphere in place any snow that does fall will have a high snow to liquid ratio allowing for a fluffy 1"-2" area wide - maybe up to 3" but totals shouldn't rise much past that. The snow will fall after 10pm tonight and last through your Friday morning commute. Clouds will stick around through the afternoon with some light snow or flurries lingering into the afternoon. Temperatures drop once again Friday night with wind chills by Saturday morning dipping below zero. Another, more significant, system will impact us Sunday through early next week with a mixture of snow, sleet, freezing rain and rain. Details on that storm will be coming up in another post. Stay tuned!
