Widespread showers are in progress over SE Mi generally south of the
Tri Cities and northern Thumb. There is a chance of locally heavy
rainfall in this pattern through early morning, especially toward
the Ohio border. Event total amounts of 0.5 to 1.0 inch are likely
along and south of I-69, with a chance of localized totals around
1.5 inches mainly south of Detroit to the Ohio border before
intensity diminishes considerably around sunrise. These rainfall
totals and time ranges suggest the potential for flooding will be
limited to ponding of water on roadways and other prone areas.
