Northern Illinois residents are bracing for a mix of severe weather this weekend, including a storm threat on Sunday, followed by a sharp drop in temperatures and the potential for snow early next week. The severe weather will bring gusty winds and heavy rain on Sunday, but by Tuesday, colder air will settle in, bringing the possibility of snow and slippery roads.
What to Expect on Sunday: Storms and Gusty Winds
A strong weather system is expected to move through Northern Illinois on Sunday afternoon, bringing heavy rain and gusty winds. Areas in and around the Chicago metro are likely to see winds gusting up to 40 mph, which could create hazardous travel conditions, especially for high-profile vehicles like trucks and buses. Along with strong winds, 1 to 2 inches of rain could fall in some areas, increasing the likelihood of localized flooding, particularly in low-lying regions and places with poor drainage systems.
The storm’s intensity could also bring the risk of severe thunderstorms. While the chances of tornadoes are lower, there’s still a possibility of hail and damaging winds. Thunderstorms could pop up during the late afternoon and evening hours, and travelers are advised to stay aware of rapidly changing conditions.
A Cold Change: Snow and Freezing Temperatures by Tuesday
Once Sunday’s storm moves out, Northern Illinois will see a dramatic drop in temperatures. Monday will bring cooler air, with highs only in the 40s, but the real chill arrives on Tuesday. The mercury could plunge into the low 30s by Tuesday morning, creating the perfect conditions for snow.
As temperatures drop, there is a growing likelihood of 1 to 3 inches of snow across the region, particularly north of I-80. The snow will begin to fall early Tuesday morning, with heavier accumulation possible by the afternoon. The snow could disrupt the morning commute, creating slick and hazardous road conditions.
How to Prepare for Sunday and Tuesday
To ensure you stay safe as the storm and snow move in, here are some important preparations to keep in mind:
-
Sunday Storm Prep: If you have to travel on Sunday, be sure to check weather conditions before you leave. Heavy rain and gusty winds can make driving difficult, so slow down and increase your following distance. If possible, avoid traveling during the peak of the storm.
-
Snow Preparation for Tuesday: Snow could cause travel delays on Tuesday, especially during the morning hours. Keep a shovel or snow blower ready, and consider delaying travel if you can. Keep your vehicle stocked with essential supplies, including a blanket, extra water, and snacks.
Potential Impact on Travel
Both the Sunday storm and Tuesday’s snow could make travel challenging across the region. Flooding from heavy rainfall could lead to road closures on Sunday, and snow accumulation on Tuesday could lead to slippery conditions, especially on untreated surfaces.
Drivers should be cautious, as untreated roads could quickly become icy, especially with Tuesday’s early snowfall. School and work commutes may be disrupted, so plan accordingly.
Looking Ahead: Cold Weather Sticks Around
After the snow clears on Tuesday, temperatures will stay below average for the remainder of the week. Highs will only reach the 30s, and although more snow isn’t forecast, the cold temperatures will make it feel like winter is still hanging on.
