Summer has brought an unexpectedly, unrelenting rainy season to the Midwest.

A wet June turned worse after strong weekend storms drenched the Midwest, strengthening worries that already serious flooding won't go away anytime soon, according to Fox News.

Showers and thunderstorms will become more widespread today with the wet weather reaching from Minneapolis to Indianapolis through Detroit and Cleveland. Some thunderstorms are expected to turn severe later in the afternoon.

Wind gusts and downpours are the most common threats that the Midwest has had to contend with, however, a few isolated tornadoes occasionally accompanied the strongest storms, according to AccuWeather.

Parts of Missouri saw nearly 2 inches of rain over the weekend.

St. Louis received 13.1 inches of rain this month, 9 inches above normal, which set a June record.

Records kept since 1874 indicate that this has been the second wettest month for the state since August 1946, with a record of 14.78 inches.

In a chart on the National Weather Service website, you can see the concentration of floods in the Midwest compared to the rest of the nation.

The Mississippi River neared a crest of 12 feet above flood stage, and the Fabius River spiked 10 feet above flood stage, topping sandbags on a levee.

Other rivers in the region were hit just as hard with the Illinois River reaching about 10 feet above flood stage, and the Ohio River climbing toward an expected crest 7 feet above flood stage.

This situation lies in stark contrast to the Pacific Northwest where a heat wave has left the region bone dry.
