Sunny days in abundance

Early fall in interior North America is described as “warm, sunny days and cool clear nights”. Chicago has been living up to that description in recent days. However, daytime temperatures crash about 10° with cold frontal passage early Friday, but the sunny days continue. So far in September, Chicago is sporting 89 percent of possible sunshine. If the month closes out with this much sunshine, as it might, it would be the second sunniest month since records began in 1893. Only sizzling July, 1916 had more sunshine. Meanwhile in the tropics, Ivan has been upgraded to a tropical depression and forecast to strengthen before landfall along the Texas coast. Current forecast for the unpredictable Hurricane Jeanne brings it dangerously close to the southeast coast.
