WINTER STORM ALERTS have been issued for the entire Stateline, beginning Friday night and running through early Sunday morning. Jo Daviess, Stephenson, Carroll, and Whiteside Counties have already been upgraded to a WINTER STORM WARNING while remaining counties in our area are still under a WINTER STORM WATCH for now.
Much of Friday will begin dry, but snow will move in from the West after 12AM Saturday morning and won't stop until Sunday morning. Initial snow may come down lighter, as dry air works to limit accumulations at first.
By Saturday morning, steady to heavy snow will be possible with snowfall rates nearly 1" per hour at times. This will continue through all of Saturday, making travel very difficult to near impossible. The heaviest of the bands may be confined to Saturday afternoon and evening, but at least a steady snow will persist through the entire day. With the recent cold surface temperatures, snowfall will accumulate very quickly and will be difficult to keep roadways clear.
Drier air will wrap in toward the back edge of the system Sunday morning, winding down the snow after 5-6AM. That is when most of the winter storm alerts are currently scheduled to expire. Though the snow may wrap up by midday Sunday, blowing and drifting may remain possible well into the evening as winds could gust to around 20-25 miles per hour.
Total snowfall from Friday night through Sunday morning will likely be between 6-10" for most in the Stateline. Northern edges of the area in Southern Wisconsin and far NW Illinois may end up on the lower end of that spectrum if the system trends any further South. Further updates will continue to be posted here and on social media accounts, so stay tuned for refined updates!
