Chicago’s veteran Midway weather observer, Frank Wachowski, measured 100 percent sunshine both Thursday and Friday — the first time this has occurred on consecutive days here since Nov. 4-6, right after the Cubs won the World Series. The sun helped boost Friday’s high temperatures to 86 degrees at Chicago’s official O’Hare observation site. The area’s highest reading was 90 degrees at Kankakee.
With low pressure and the associated cold front far to the north, temperatures are expected to peak in the upper 80s both Saturday and Sunday, giving us the warmest weekend since Aug. 27-28. Gusty west-to-southwest winds will push these very warm temperatures right up to the Lake Michigan shoreline.
An upper-air disturbance may trigger a period of showers and thunderstorms Saturday night.
