The 13th and final weekend of meteorological spring is likely to be the season's warmest. And half of the season's copious rainfall -- 6.78 inches of the 14.02 measured at O'Hare International Airport since March 1 -- has occurred during the past 12 weekends.
After a series of cloudy days reduced temperatures in the Chicago area, the return of sunshine will boost readings Friday substantially. A light wind regime means daytime heating could encourage the cooler, denser air that hugs Lake Michigan's surface to ride into shoreline areas as a lake breeze Friday afternoon.
Think May's been cold? Last May was cooler
Chicagoans may be surprised to hear that May, which ends Sunday night, is actually running a bit warmer than normal. The month's 59.6-degree average temperature is 1.7 degrees above the 138 year long-term average and a full 5 degrees ahead of the same period a year ago.
