There will be daily chances for scattered thunderstorms across portions of the Central and Eastern U.S. through the weekend, with severe thunderstorms possible in the northern Plains and Upper Midwest. Potential severe storm hazards may include large hail, damaging winds, and a few tornadoes. Storms could also produce heavy rain that may lead to isolated instances of flash flooding. Read More >

Overview Late on the night of July 11 into the morning of July 12, multiple waves of thunderstorms moved across southern Wisconsin and northeast Illinois. With summertime moisture at its maximum, the storms produced copious rainfall rates. Given the training nature over the same location, substantial rainfall amounts resulted. This brought flash flooding by daybreak on July 12 that continued through that entire day and into the next night. In addition, river flooding became a major problem and continues, especially on the Des Plaines and Fox Rivers. For more on the rivers, visit our AHPS page. |
