12:10pm Update: Visibility continues to fall under the heavier snow bands moving through S. WI and N. IL. Again, snowfall amounts won't be much but the impact of the wind, blowing snow and lowered visibility will make roads slick through the early afternoon. Please be aware
when heading out!
10:55am Radar Update: Visibility is lowering in Northwest Illinois as the heavier snow begins to cross over the Mississippi River. Heavier snow bands moving through Green and Stephenson counties.
Other than just a few lighter snowflakes flying through the skies early this morning the biggest issue at hand will be the wind. Strong south winds gusting over 30 mph have caused blowing & drifting snow in mainly open and rural areas. In fact, we've already received a few reports of roads - IL Rt. 173 and Rt. 20 - that were already experiencing blowing and drifting snow.
By late morning/early afternoon the heavier snow band in Eastern Iowa will have moved into Northern Illinois and Southern Wisconsin. A period moderate snowfall will be possible during the afternoon which, when combined with the wind, will lower the visibility to less than a mile and create a few slick spots on the roads. Snowfall accumulations won't be much and remain between 1-2" for most, but the impact the wind will have on the falling snow will be high. By this evening the majority of the snowfall will have ended and temperatures will fall back into the single digits late tonight.
