Chicago, IL – Holiday travelers using Interstate 90 may face sudden and fast-changing driving conditions next week as a series of disturbances could bring brief but intense snow bursts from Saturday, December 7, through Friday, December 13, according to early guidance from the National Weather Service (NWS). Officials say the pattern may lead to unpredictable slowdowns along multiple stretches of the interstate.
According to the NWS, several fast-moving systems linked to the broader Alberta Clipper pattern may sweep across portions of the Upper Midwest, Great Lakes, and Northeast. While these systems typically move quickly, they can produce sudden drops in visibility, slick pavement, and short-lived but impactful bursts of snow—conditions that often catch drivers off guard.
Travel impacts may vary widely along I-90’s extensive route, which spans major regional hubs including Minneapolis–St. Paul, Madison, Chicago, South Bend, Cleveland, Erie, Buffalo, Rochester, and Boston. Forecasters say some areas may experience only brief flurries, while others could see enough accumulation to affect both morning and evening commutes.
Because these systems tend to develop with little advance notice, the NWS cautions that road conditions may change rapidly as each disturbance passes, especially overnight and during early holiday traffic surges. Drivers may encounter patchy blowing snow, isolated whiteout conditions, and icy stretches on bridges and overpasses.
Officials advise motorists to check updated forecasts daily, allow extra travel time, and remain alert for changing conditions through the entire December 7–13 window.
