The calm, cool weekend around Chicago may be the quiet before a serious weather shake-up. Forecasters are urging residents to use the lull to get ready for a potentially significant severe weather outbreak on Monday, April 27. The National Weather Service is warning that "all hazards" could be in play across parts of Illinois, including tornadoes, damaging winds, hail and heavy downpours.
When The Storms May Arrive
Storms are expected to start moving into the region around 1 p.m. on Monday, with an environment that could support organized severe thunderstorms capable of large hail and damaging wind, according to NBC Chicago. Forecasters caution that the exact timing could still shift as the system develops. The National Weather Service's Hazardous Weather Outlook highlights a notable risk for severe thunderstorms across the area on Monday.
River And Flood Concerns
Recent high water may not be done with the region yet. Local rivers that just flooded could see another bump if heavy rain materializes. "They could rise again from Monday's storms," NBC 5 Storm Team meteorologist Kevin Jeanes said of area rivers, according to NBC Chicago. A flood warning remains in effect for some stretches, and officials are urging residents near the Fox, Rock and Des Plaines rivers to monitor water levels and avoid flooded roadways. Heavy rain and localized flooding are also possible with the storms.
How To Prepare
The National Weather Service is nudging people to do the unglamorous but important work of getting ready before the storms arrive. Residents are urged to review their safe place, gather emergency supplies and make a family communication plan ahead of Monday's storm, according to NWS Chicago. If you have outdoor plans, consider shifting them indoors or postponing until the threat passes.
Where To Get Updates
As Monday approaches, officials recommend keeping a battery-powered radio or NOAA Weather Radio on hand, following NWS Chicago on X and staying tuned to local media for watches and warnings. Local stations like FOX 32 Chicago and NBC 5 are expected to carry live updates as the situation develops.
