A surge of warm and humid air will be followed by a dramatic temperature drop this weekend.  The warm front is responsible for all the heavy rain and flooding through the morning drive and will keep scattered storms around into the evening hours.  Some storms could be strong to severe with damaging winds, frequent lightning, isolated tornadoes and more torrential rain.  

This low pressure system will continue its journey through the region on Friday.  A strong cold front will sweep through forcing a line of storms through Metro Detroit during the afternoon.  Winds will also significantly increase tonight through Friday night, which has prompted Gale Warnings on the Great Lakes.  Significant waves of 11' to 16' will be possible during peak wind gusts Friday evening.  Once the front clears the area Friday night, cooler and drier air will rush in behind it causing temperatures to tumble.

Locations across the Upper Peninsula and Northern Lower Michigan could face a 30-degree or more temperatures drop within just 24 hours.  From the 60s Friday morning to the 30s and 40s Saturday morning could also set the stage for Michigan's first widespread frost this weekend across Northern Michigan and the U.P.  This will come just hours before fall official arrives Saturday night at 9:54 PM.
