A Blizzard Watch is in effect until Wednesday 6pm for: Winnebago, Boone, McHenry, Ogle, Lee and Dekalb County.
A Winter Storm Watch is in effect until 3pm for: Rock and Walworth County.
Our next two rounds of winter weather are quickly approaching and will affect the entire viewing area. The first round can be expected by Monday and last through Tuesday morning. Snowfall can be moderate at times Monday afternoon and into the early evening hours. This round of snow will lighten up by Tuesday morning with total accumulations around 2-4 inches with some localized areas receiving up to 6 inches in southern Wisconsin.
The second round comes in late Tuesday afternoon and lasts into Wednesday. The models show a storm track from northern Arkansas sliding northeast into Central Ohio. This scenario will likely create a heavy band of intense snowfall over the entire Stateline region. Total accumulation from both rounds of snow could range anywhere from 8-12 inches with a few isolated areas receiving more. Cities that are closer to the Chicago area are likely to receive more due to Lake Enhanced snow, which will create an impact on all roadways and flights out of Chicago. Traveling will become very difficult due to the heavy snowfall and the gusty winds. Blizzard like conditions can be expected Tuesday overnight and into Wednesday as winds gust up to 30 mph. This will cause visibility to become less than a half a mile at times. After the system passes, a cold arctic air mass will create wind chill factors between 15 to 25 below zero by Wednesday night and into Thursday morning.
