Chicago is preparing for its significant first snowfall of the season, as a winter storm is set to hit the city Sunday night. The National Weather Service has issued a winter storm warning from midnight Sunday through noon Monday, forecasting up to eight inches of snow.
Winter Storm Forecast Details
This winter storm is expected to deliver a substantial amount of lake-effect snow. The Chicago area may experience six to ten inches of snowfall, with potentially higher amounts near the lakefront. According to meteorologist Gino Izzi, a “ferocious, thin band of snow” is anticipated to move in Sunday night. This intense snowfall could bring two to three inches of accumulation per hour.
Impacts on Local Areas
- Areas closest to the lakefront face over a 70% chance of receiving eight or more inches of snow.
- Snowfall is likely to lead to hazardous driving conditions Monday morning.
- Potential for traffic snarls as the heavy snow impedes snowplow efforts.
Izzi warned residents of the challenges of reacclimating to snowy weather, particularly blizzard conditions. He suggested that drivers prepare for the possibility of being stuck in their cars for extended periods if they venture out during the storm.
Unique Storm Characteristics
This winter storm will feature notable lake-effect snow, resulting from a storm system moving over warmer air above Lake Michigan. This leads to increased moisture release as snow. November is typically when Chicago sees its first snowfall, but the intensity of this particular storm sets it apart.
Historical Context
Izzi noted that conditions yielding up to three inches of snow per hour last occurred in February 2021, highlighting the unusual nature of this storm. Snowfall is expected to taper off by Monday afternoon, with temperatures forecasted to rise above freezing later in the week, potentially reaching highs of 55 degrees by Thursday.
