Umbrellas and raincoats will be put to good use across the Midwest this week as a stormy weather pattern sets up over the region.
Showers and thunderstorms will be widespread across the Midwest most days this week. However, no day is expected to be a complete washout.
Showers and thunderstorms will become more widespread into Tuesday with the wet weather reaching from Minneapolis to Indianapolis and through Detroit and Cleveland.
Some of the thunderstorms are forecast to turn severe during the afternoon hours, particularly those reaching from central Ohio through central Kentucky into Monday night.

Damaging wind gusts and torrential downpours will be the most widespread dangers with a few isolated tornadoes possible with the strongest storms.
Afternoon and evening commutes my be interrupted due to the timing of these storms, particularly along portions of I-64, I-70, I-71, I-74, I-75 and I-77.
A small batch of strong thunderstorms may develop over northern Wisconsin and eastern Minnesota on Monday afternoon as well, but these storms are not likely to be as intense as those in the Ohio Valley.

Anyone looking to get work done in the outdoors either of these days should try to do so in the morning, as the afternoon looks to bring the greater chance for showers and storms.
A small number of storms may turn severe each afternoon, especially around the Ohio Valley.
While not as strong as Sunday's storms, those on Monday and Tuesday can still bring wind gusts strong enough to bring down trees and cause sporadic power outages.

Wednesday is forecast to bring a small break in the unsettled weather for much of the region, but showers and thunderstorms will ramp back up for Thursday and Friday.
In addition to all of the rain and travel disruptions, the wet weather pattern will also keep temperatures below normal through much of the week.

This wet weather pattern is nothing new to the Midwest. The past several weeks have been unusually wet in this part of the country, especially in areas south of the Great Lakes.
"In portions of Iowa, Missouri, Illinois, Indiana and Michigan, rainfall since May 1, 2015, has been twice that of normal," said AccuWeather Senior Meteorologist Alex Sosnowski.
As a result, river levels are running higher than normal with portions of the Mississippi and Illinois rivers in a major flood stage, according to the National Weather Service.
With more wet weather on the way, flooding along these rivers is likely to continue through the week, while at the same time bringing a renewed flood threat to areas that have seen flood waters recede.
The rain that falls through Tuesday will also add to the impressive rainfall totals across the region for the month of June.
This month has become the wettest June on record in St. Louis with the city receiving over 13 inches of rain. this broke the old record of 12.69 inches set back in 1948. In Illinois, the average rainfall for the state set a June record.
Because of the prior rainfall and localized downpours the thunderstorms will bring, flooding can be renewed or made worse this wee.
