One more stormy day ahead for Metro Detroit View Comments Storms that prompted a flash flood warning for northeastern Wayne County have left the region, but there's still a chance for severe weather before calmer conditions settle in to end the week, the National Weather Service said Wednesday evening. Showers and thunderstorms are possible Thursday as temperatures reach the upper 70s, but none should resemble the recent downpours, meteorologist Steve Considine said. "Tomorrow we’re getting a system dropped down from Canada which is going to bring cooler, drier air," he said. "We’re seeing a major shift, which is why our threat for heavy rain is ending."
