Severe weather systems are expected to impact the Upper Midwest, Mid-Atlantic, and Northeast regions through Wednesday.

A multiday severe weather event is set to begin this workweek, bringing a risk of strong thunderstorms, damaging winds, large hail, and isolated tornadoes. The FOX Forecast Center reports that the system will move from southern Canada into the Great Lakes, creating favorable conditions for storms across the Upper Midwest. By Tuesday, the threat will shift into the Ohio Valley and central Appalachians. By Wednesday, the severe weather will track into the Mid-Atlantic and Northeast, including the I-95 corridor. Meteorologists warn that flash flooding is likely each day as deep moisture pools ahead of the cold front. In Chicago, JD Rudd noted that while the ground is dry from a 14-day rainless spell, high rainfall rates may cause localized pooling. Additionally, wildfire smoke from Canada is currently affecting air quality, though it is expected to clear by Tuesday. Following the passage of the cold front, the region will transition to cooler, drier conditions with temperatures remaining below normal for the remainder of the week.
