Showers and thunderstorms restrict heating in Chicago

|
The stormy period that began Sunday afternoon should end later today as a cold front pushes south of of the Chicago area. The Storm Prediction Center posted severe thunderstorm watches Sunday afternoon and evening along the cold front from northern Kansas through northwest Missouri, a good portion of Iowa, northern Illinois, and southern Wisconsin into extreme northern Indiana as well as most of Lower Michigan. Iowa seemed to be hardest hit with many reports of one-and-a-half to two-inch hail along with extensive wind damage. Trees and power lines were down in many locations across southern Wisconsin and Lower Michigan.
Locally heavy downpours were reported in a few spots across northern Illinois. Cloudiness from the storms cut off heating and restricted Chicago area highs to the lower 90s, holding heat indexes to around 100 degrees. Highest readings were at Northerly Island where the high peaked at 93 degrees with a heat index of 103.

Fair skies expected the rest of the week
The upper-air pattern will favor an extended period of fair skies and rain-free weather over Chicago beginning Tuesday and continuing into next weekend.
