The calendar may read November 5, but the Stateline's already on the precipice of its third measurable snowfall of the young cold season. A weak Alberta Clipper-type system is taking aim on the area as we speak, already spreading light snow into portions of Western Wisconsin. That snow's likely to become more widespread in nature in the hours ahead, with growing chances of the snow reaching our area after midnight.
Snowfall here's not to be heavy, nor is it guaranteed to fall across the entire region. The greatest risk for snow is to be found north of the Rockford Metro, where Winter Weather Advisories remain in effect over a sizable chunk of Wisconsin. Snowfall chances taper off dramatically as you head south of Rockford, with many locales along and south of Interstate 88 quite possibly avoiding snow altogether.
As far as snowfall amounts go, it's hardly expected to be a barn burner. In fact, the vast majority of the area will see well under an inch of accumulation. Communities immediately along or just north of the Wisconsin border are the most likely candidates to pick up an inch or perhaps slightly more by sunrise.
With colder temperatures having dominated for the better part of the past few weeks, though, even the slightest accumulations may result in slick spots on our roadways coinciding with Wednesday's morning commute, so caution is urged for travelers in the early portion of the day.
