Isolated Severe Storm Risk Tonight; Rain May Cause Rivers To Rise (Updated 10:40 PM 4/19)

The Storm Prediction Center's severe weather outlook now shows a Marginal Risk for severe storms across southern Wisconsin overnight (what do the risk categories mean?)

See the graphics below:

Look for the strong thunderstorms from Iowa to track east northeast through southern Wisconsin during the overnight hours.

A Marginal Risk means that an isolated severe storm is possible. Large hail and strong winds would be possible.

Moderate to heavy rainfall may occur over parts of southwest, central and northeast Wisconsin, with amounts in excess of 1 inch possible, especially overnight. Lower amounts are forecast elsewhere.

Some rivers are already running relatively high, so more rain may put some area rivers into flood stage later in the week. Again, keep up with the latest forecasts!
