Persistent rain and scattered thunderstorms associated with a stationary front may produce greater than three inches of rain by the end of the week. The image below (click to enlarge) shows expected rainfall through Friday.
The heavy rain will probably cause flooding of smaller rivers, creeks and streams as well as ponding of water on roads and in low lying areas. Basement flooding will be possible in homes that typically experience problems during heavy rain. Some of the larger rivers such as the Grand, Kalamazoo, and Muskegon may see significant rises by late in the week into next week.
Colder air is expected to arrive from the north on tonight and linger through Friday. This will bring a threat of freezing rain along and north of Whitehall to Alma line. A risk for up to one half inch of ice exists-- during the period from tonight through Friday.
