A center of intensifying low pressure will track out of Missouri northeast today, passing over Chicago early afternoon, through Lower Michigan into Ontario Canada by this evening.
Temperatures will slowly rise this morning with showers and thunderstorms possible much of the day – even a few severe storms could occur directly south and east of Chicago (see Slight to Marginal risk area outlined on the map below).
Very strong west to northwest winds gusting to 40 mph will signal a change to much colder conditions behind the departing low pressure. Rains will cause additional rises on area rivers, note Flood Warnings/Advisories in green on the headlined map.
