Overview

• The Storm Prediction Center rates Wednesday’s severe threat as level one of five for the Chicago area.
• Isolated to scattered showers could develop between 3 p.m. and 9 p.m., though many neighborhoods may remain dry due to spotty storm coverage.
• The National Weather Service cautions that any storms that form could produce gusty winds, frequent lightning and heavy downpours.
• Daytime highs will hit the low 80s by Lake Michigan and climb into the mid-90s inland ahead of Thursday’s humidity surge.
• Thursday night’s storm potential gives way to a better chance of widespread rain on Friday, a dry Saturday and renewed scattered storms on Sunday.
