Springfield, IL – Illinois residents can expect a significant shift in weather conditions this week as warm, breezy conditions give way to storms and snow. High temperatures will reach the 70s by Tuesday, but a strong storm system will bring thunderstorms, gusty winds, and a cold front by midweek.
According to the National Weather Service (NWS) in Central Illinois, winds will reach 30 to 40 mph Monday, especially north of I-70. Tuesday remains warm with highs in the mid-70s, but by Wednesday, a strong system will move in, increasing the risk of thunderstorms and heavy rain.
By Wednesday night, colder air will sweep through Illinois, causing rain to transition into snow across much of the region. While exact snowfall amounts remain uncertain, residents should prepare for slippery roads and reduced visibility. Temperatures will drop sharply, marking a stark contrast from the unseasonably warm start to the week.
Officials urge residents to stay updated on forecasts and secure outdoor objects ahead of the high winds. Travelers should plan for changing road conditions, especially late Wednesday into Thursday morning.
More updates will follow as the system develops.
