CHICAGO, Illinois — Northern Illinois is heading into a two-day stretch of storm chances, and forecasters say Tuesday afternoon is the moment residents need to be watching most closely.
The National Weather Service Chicago office says scattered showers and embedded thunderstorms are expected to develop early Monday morning, mainly before noon.
The highest storm coverage Monday is expected northwest of the Fox Valley and near the Interstate 55 and Interstate 57 corridors — roughly between 8 a.m. and midday.
Monday Morning: Storms, But Not Widespread Severe Weather
Monday’s early storms are not expected to be a major severe weather event — but they are not something to ignore either.
Gusty winds, frequent lightning, and localized heavy downpours are all possible during the morning hours.
Forecasters also say how Monday morning plays out matters a lot for what comes later in the day.
Monday Afternoon: A Lower-Confidence But Real Threat
If storms manage to reform during Monday afternoon and evening, isolated severe storms could develop.
Damaging wind gusts and hail up to quarter size would be possible in that scenario.
However, the National Weather Service notes that confidence in Monday afternoon storm redevelopment remains lower at this time — meaning it is possible, but not a sure thing.
Tuesday Is the Day to Prepare For
The more organized and dangerous severe weather potential arrives Tuesday afternoon and evening.
A cold front moving into Illinois is expected to bring the strongest storm threat, shifting southeast across the Chicago metro, Joliet, Kankakee, northwest Indiana, and portions of central Illinois.
Damaging winds are the primary concern Tuesday — but hail up to quarter size is also possible with the stronger storms.
The National Weather Service currently places much of northern Illinois under a Level 2 severe weather risk for Tuesday, meaning scattered severe storms are expected to develop.
What You Should Do Right Now
Do not wait until Tuesday morning to prepare. Here is what forecasters and emergency managers recommend:
- Enable weather alerts on your phone tonight
- Monitor National Weather Service updates Monday night into Tuesday
- Have a plan for where to shelter if severe weather strikes during the day Tuesday
- Keep an eye on rapidly changing forecasts — storm tracks can shift
The window between Monday night and Tuesday afternoon is your best time to stay ahead of this storm system.
