Mariann, who is from Bridgeview, IL, snapped this photo Tuesday of what she refers to as a “UFO cloud” while visiting Palm Springs, California. It’s not unusual to hear such clouds referred to as UFO-like because of their lens-like shape. Lenticular clouds are a form of “standing wave” cloud–a stationary, comparatively high altitude lens-shaped cloud which can linger for some time as air flows over mountain ranges. The fact that mountain ranges are fixed in place means air ascends at the same location producing a cloud which appears to linger for some time. The cloud Mariann captured in this shot Tuesday is precisely such a cloud. What a TERRIFIC shot! THANKS for sending this along, Mariann!

Chicago remains mired in the chilliest early October in 22 years. The opening 14 days of the month, with an average temperature of 47.6-degrees, are well below the 57.3-degrees observed during same period over the past 138 years and 10.7-degrees cooler than a year ago–chilly enough to rank third coldest since 1871. The only Oct. 1-14 periods which have been colder occurred in 1876 (46.0-degrees) and 1987 (47.5) underscoring just how unusual the current chilly spell is.
All indications point to Thursday becoming the 18th consecutive day temperatures post a deficit and the sixth day highs fail to reach 50-degrees, establishing a new record for the most early season daytime readings which fail to break out of the 40s. With both Friday and Saturday predicted to stay in the 40s, the string is likely to end up at 8 days, something which doesn’t happen here most years for another 5 weeks.
Rain falls across the Chicago area Thursday, the latest offshoot of a mammoth Pacific storm system which has whipped the West with 100 mph mountaintop wind gusts in recent days and stunning rainfall up against some of California’s westward facing mountains. Totals reached 21.34 inches at Mining Ridge in Monterey County, roughly halfway between San Francisco and Los Angeles. A wind gust of 135 mph whipped Tahoe City, Nev. Wednesday and gusts of 70 mph raked San Francisco. Even sections of the Salt Lake City, Utah area registered 50+ mph gusts.
So far this October the highest temperature has been just 62 degrees and the forecast calls for continued chilly weather. Have we ever had an October that has failed to produce a 70 degree day?
October is usually Chicago’s last nice month before the dark, damp and chilly days of winter set in. Typically the area sees about 10 days with highs of at least 70 degrees, and usually there are at least a couple of days in the 80s. Checking temperature records dating back to 1870, climatologist Frank Wachowski found only two Octobers that failed to produce 70 degrees–1885 and 1917. In sharp contrast to those years, October 1963, the city’s warmest on record, was a banner year for days of 70 or higher– with 24 on the books. That month tallied 11 days in the 70s, 12 in the 80s and even a 94 on Oct. 6.
These beautiful photos come to us from Allison Phelps at The Morton
Arboretum. Allison tells us:
” We have trees from 40 countries, so there are many unusual species to share with you – trees not likely seen in your local park or forest preserve.”
How interesting, Allison! It’s wonderful of you to keep us posted on the
fall color progression at the Arboretum! THANKS so very much!

Wednesday was a great morning, I went to Kingsley Elementary in
Evanston and visited the 1st graders. They asked some great weather
questions and even got to see Stormy Weather and Blue Sky in their
Halloween costumes. Stormy (super dog) Sky (a nice witch).
