2nd Coolest Weekend Of Summer
After six straight days with highs in the 90s we finally have some relief from the high heat and humidity. This will be the coolest weekend we have seen since the middle of June and the second coolest weekend of summer. Yesterday's high of 95° marked the 31st 90-degree day of the year so far. 2020 now ties 1987 for the third most 90-degree days on record for a year.
No more 90s in sight at least through next week. Today's highs will reach into the upper 70s and lower 80s.
Wednesday will probably be the warmest day of the week coming up with highs in the lower 80s or just a bit above average (80° is average high for this time of year). Highs slip back into the 70s by the end of the week again. The temperature anomaly forecast for Thursday afternoon shows a big blob of blue from the plains into the midwest. Temperatures are forecast to be anywhere between 10° to almost 20° cooler than average. We may hit highs near 80° that day but a cold front will come through with falling temperatures late in the day.
Only a trace of rainfall at O'Hare on Friday. Rainfall is now down by nearly 5 inches compared to average since July 1st. The chances for rain this upcoming week are few and far between. The next chance of rain is Tuesday and after that we have to wait until next weekend. This is bad news considering parts of the area have slipped into a moderate drought.
The shift in winds that is bringing in cooler and less humid air will whip up some big waves and strong rip currents along Lake Michigan's shoreline. Waves could build up to 3 to 5 feet on the Illinois shores and as big as 4 to 7 feet on Indian's shores. A beach hazards statement is in effect until 7 pm because of the dangerous swimming conditions. The National Weather Service warns that people should stay out of the water during this time.
Our shift to a cooler pattern could continue through the middle of September. The 6-10 and 8-14 day day temperature probability forecast have us outlooked for cooler than average temperatures from September 3rd through September 11th.
Still some hope for more rainfall in the longer range precipitation probability forecast. At least the 6-10 day forecast has us favored for above average rainfall overall from September 3rd through the 7th.

Today: Partly to mostly sunny, a bit breezy High: 80
Sunday: Partly to mostly sunny Low: 60 High: 78 (73 Lakefront)
