FIRST, THE MONDAY WEATHER HEADLINES

–The just completed weekend came on 7-deg warmer than last weekend

–Thundery overnight rains, with their dramatic lightning displays and hail reports in parts of the area, totaled just 0.03″ at Midway Airport, 0.44″ at O’Hare and as much as 1.88″ at Arlington Heights

–Up to 9,000 cloud to ground lightning strikes occurred between 8pm Sun night and 2am CDT Monday morning, according the National Weather Service

–Temps are to flirt with 90-deg Tuesday–but cool dramatically to the 60s later in the week on Thursday and Friday–just in time for the astronomical beginning of the fall, 2022 season at 8:04 pm Thursday evening

–A 90 deg high Tuesday would make it the warmest day in over a month–in fact in 6 weeks here–the previous warmest being 95 on August 6th.

–The coolest air since last May (in 4 months) may see temps Friday only in the low or mid 60s.
