Friday is forecast to be very warm with highs well into the 70s and potentially as high as 80 with wind gusts up to 45 miles-per-hour, ABC7 Accuweather Meteorologist Tracy Butler said. Butler says the severe storms will start moving into the area around 10 p.m. and move out around 3 a.m.

What started as a summer-like day Friday will end with potentially severe storms as a powerful system prepares to sweep across the region, but there's a narrow window of time you'll want to make sure you're prepared for.
