This is the Severe Weather Outlook Map from the Storm Prediction Center for this (Mon.) afternoon. The highest risk for a severe thunderstorm this afternoon is in the Enhanced Risk Area (in orange on the map) from E. Iowa into N. Illinois. Surrounding the Enhanced Risk Area is a Slight Risk Area (in yellow on the map) that includes the area south of a line from Grand Haven to west of Coldwater. Surrounding the Slight Risk is a Marginal Risk Area that covers the rest of Lower Michigan. SPC says: “Severe thunderstorms capable of damaging winds are forecast to move across parts of Iowa, Illinois and S. Wisconsin this afternoon.” Michigan is not specifically mentioned in the discussion. Bottom line…severe weather is possible, but not likely this PM with the greater threat to our southwest.
We have a chance of a shower or storm this afternoon/tonight, then dry weather will dominate from tomorrow (Tue.) through at least Friday. Storms are possible again next weekend.
