Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
Flood Watch through Sunday morning...
Scattered showers will develop today. These showers will be light and drop only a half an inch of less. As a storm system to our SW strengthens it will move into our region going into Saturday. Rain will develop and become very heavy at times. Rainfall on the order of 1.5 to 4 inches with locally higher amounts could be possible. The heaviest totals will be NW or the I-71 corridor. SE or I-71 rainfall totals will drop significantly. This kind of rainfall on top of recent snow melt will cause serious issues over the weekend. Significant flooding is going to cause very dramatic rises on rivers, streams, and lakes. Please be ready should flooding occur.
Some areas may experience very strong winds mainly on Saturday night and Sunday with the passage of this very strong cold front. Stay tuned for further details.
