The temperature at O’Hare airport reached 95 degrees Monday afternoon, coming just three degrees shy of the record for the date. This was the highest temperature recorded during our latest hot spell, which brought three straight days of 90-degree readings and triple-digit heat indexes.
Thunderstorms erupted along a southbound cold front during the late afternoon, sending cool storm outflow across the metro area. By 7 p.m., areas along and north of the I-88 corridor had cooled more than 20 degrees. The front that initiated Monday’s storms will settle south of the area, establishing a cooler, northeast wind flow that is to persist through the upcoming weekend.
More rain is expected in what has been a soggy June. Though the focus of heavy thunderstorms will have shifted south of the area by Tuesday afternoon, another weather system is forecast to bring a heavy rain threat Friday.
