‘All hazards’ possible during severe weather threat on Monday across Chicago area after cool weekend

Chicago-area residents should use the weekend of calm weather to prepare for a storm expected to hit the region on Monday that has the potential to bring “all hazards,” including tornadoes, officials said.

Though weather over the weekend is expected to be fairly quiet, with highs in the low 60s and sunny skies, a shift is expected on Monday.

“Concern continues to increase in a threat for a severe weather outbreak across the region on Monday. All hazards, including tornadoes, will be on the table. Now is the time to prepare!” the National Weather Service said on social media Saturday morning.

In addition to tornadoes, damaging winds and hail are possible, NWS said.

Where exactly the worst weather will hit is still uncertain, NWS said. As the storm gets closer, shifts in the outlook are possible. As of Saturday morning, most of Illinois is under a level 3 severe weather threat. Part of northeast Illinois is under a level 2 severe weather threat.

The storms are predicted to roll in around 1 p.m. and anyone with outdoor plans should consider rescheduling, NWS advised.

Heavy rain and localized flooding are also possible during the storm.

Though high water levels in local rivers that led to severe flooding after recent storms are expected to drop late Saturday, NBC 5 Storm Team Meteorologist Kevin Jeanes said, they could rise again from Monday’s storms.

A flood warning will go through at least Saturday, with streets near the Fox River completely underwater.

Residents who live near Rock, Fox and Des Plaines rivers should monitor water levels during and after the “swaths” of rainfall on Monday, NWS said.

“Now is the time to prepare, including making sure you know your safe place, having a family communication plan, and ensuring you have emergency supplies,” NWS advised.
