Despite Lackluster Snowfall, Winter Storm's Impacts to be Felt Well Into Wednesday

It hasn't happened everywhere, but snowfall finally did reach at least a portion of the Stateline Tuesday Night, at long last. Areas along and southeast of a line stretching from Davenport to Rockford to Milwaukee picked up a few hours of light snowfall Tuesday Evening, though accumulations, if any, were extremely limited, and largely confined to grassy surfaces. Snow will end areawide no later that 2:00 Wednesday Morning, though the storm's impacts on the Stateline's weather will be far from finished.

On the storm system's back side, winds have been strengthening out of the north, and will continue to do so through the rest of the night and throughout the day on Wednesday. In the immediate term, the increasingly gusty winds could cause some localized blowing and drifting snow, resulting in temporarily reduced visibility.

The impacts caused by the winds Wednesday will be twofold. First of all, and most noticeably, it will reinforce a chill in the Stateline. As winds gust to 25 to 30 miles per hour through much of the day, temperatures will struggle to reach out of the 20s, and wind chills will be restricted to the teens just about all day long. At night, it's nearly certain that chills will fall well into the single digits.

The gusty winds may also make travel difficult at times Wednesday, especially for those driving high-profile vehicles. As winds gust to greater than 30 miles per hour, travel may become problematic at times, especially on east-west oriented roads.

Lastly, though not a local issue, gusty winds will wreak havoc along the shores of Lake Michigan for at least the next 36 hours. While the winds are quite gusty here, they're to be even more intense over the friction-less waters of the lake. This will allow waves to build dramatically, and crash ashore along the Chicago, Waukegan, Kenosha, Racine, and Milwaukee shorelines Tuesday Night. Those waves, swelling at times to as high as 8 to 11 feet, will likely cause some lakeshore flooding to take place, as well as continued beach erosion, which has been a long-lasting issue due to the already high lake levels. As the winds shift to more of a northwesterly direction Wednesday, the lakeshore flood and beach erosion concerns will shift more into Northwest Indiana and Southwest Michigan.
