How rare is it for Chicago to experience a 90-degree day in October?
October 90s are extremely rare in Chicago with only six on the books since 1870. The combination of shortening daylight and lowering sun angle make 90s unlikely so late in the year.
The last October 90s recorded in the city took place in 1971 when back-to-back 90s were logged on Oct. 1 (92) and 2 (91). Both of these readings established new record highs for the day.
The latest occurrence for a 90-degree day here is Oct. 6, 1963 when the mercury peaked at 94 degrees—not only breaking the record high for the day, but set the all-time high for the month.
Since 2000, the highest October temperature recorded here has been 87 degrees; peaking at that value on Oct. 4, 2005 and for three straight days during a mini-late-season heat wave from Oct. 6-8, in 2007, which affected the Chicago Marathon.
Flying through a “hole in the wall” of thunderstorms at 8,000 ft. over Springfield, Illinois this past Thursday
Our friend and ace pilot Anson Mount sends us this photo he took last Thursday flying over Springfield at the 8,000 ft. level last. He writes:
“I was actually in controlled airspace and was being directed right into this hole! It was a wall of cumulonimbus building along a wave downstate that afternoon. I like the fact that you can see the clouds in the distance!”
Very cool shot! THANKS Anson—-ALWAYS great hearing from you! By the way, Anson asks we remind you that the Waukegan Air Show takes place this weekend at the Waukegan Regional Airport. Hope the turnout is great!

It’s not your imagination–those ARE palm trees on Oak Street Beach. These pictures come to us from David W. Skyzyniarz who tells us in his e-mail that he considers riding a bike through Northerly Island–especially in the morning time of the year—-an amazing place to take in the beauty and sounds of our Chicago Lakefront. Can’t agree with you more, David. By the way, regarding the palm trees——Zvez Kubat, spokesperson for the Chicago Park District, tells me they were planted by the folks who operate Oak Street Beachstro–that’s the restaurant on the beach. The palm trees are obviously not native to our area—but Zvez tells me they are quite able to survive our winter weather. In fact, they were planted last year. Thanks to David Skrzyniarz for the pics and Zvez at the Park District!

Corrina De Maria sends us this fascinating shot taken Monday in downtown Chicago. In it, you can see a shadow being cast by the Willis Tower (formerly the Sears Tower). She writes:
“I couldn’t quite figure out why or how this happened, but while I was riding by the Sears Tower I saw it casting a shadow upon the sky! The sun was behind the building. I have my theories, but I was wondering what you thought.”
Corrina, what’s happening here is the backlit Willis Building is casting its shadow on the low “scud clouds” making their way across the Loop. You’ve caught the whole thing magnificently in your photo! THANKS for sharing it with us!

The image was produced by the European Southern Observatory’s GigaGalaxy Zoom project. The original image contains about 800 million pixels. A zoomable image can be found by clicking here. It has a measly 18 million pixels.
For you photographers, a Nikon D3 digital camera (50 mm lens open at f5.6) was used for the photos used to piece together this awesome view.
It felt like summer Monday. The 84-degree highs at O’Hare International and Midway Airports were Chicago’s warmest readings since an 88-degree high Aug. 16. Even the 73-degree water temperature along the lakefront tied the season’s highest to date. But the march continues toward autumn’s astronomical open at 4:18 p.m. Sept. 22 when the sun’s most direct rays cross the equator and head south.
An incredibly stubborn atmospheric blocking pattern, responsible for slowing U.S. weather movement to a crawl since late August, moved into its 16th day Monday. Areas like Chicago that are in the midst of dry weather remain dry while regions trapped beneath wet weather can be subjected to extraordinary amounts of rain. That was the case Monday in Pensacola, Fla., where the Naval Air Station recorded 7.23 inches of rain. The ongoing block has deflected rain-producing systems away from the Chicago area. The paltry 0.05 inches of rain recorded in the past 2 1/2 weeks at O’Hare is 2 percent of the normal amount and renders the span from Aug. 29 through Sept. 14 the driest in this area in 22 years.
