Don't tell Mom: Rain may dominate on Sunday

Saturday's sunny open isn't to last. Clouds marking the approach of a windy Mother's Day
storm expected to soak the area Sunday arrive as the day proceeds, but not before
Chicago temperatures reach the 60s away from the lakeshore. However, cooling east
winds are expected to restrict shoreline highs to the 50s.
LATE SHOWING OF BACK-TO-BACK 50s
The chill that has gripped the area since Thursday is more than a bit unusual by historic
standards. The 59- and 58-degree highs here Thursday and Friday are the first
back-to-back 50s to occur on a May 8 and 9 here in a quarter century. In addition, 80
years of weather records dating back to 1928 at Midway Airport indicate that fewer than a
third of mid-May highs fail to crack the 60-degree mark.
IT WAS WARM THIS TIME A YEAR AGO
By contrast, Chicago was in the midst of early-season warmth at this time last year.
Saturday's predicted 63 degrees falls 21 degrees short of the 84-degree high a year ago.
Interestingly, last year's first 90-degree day was to occur in only a week's time on May 14.
May 2007 ended up with 13 days of 80 degrees or higher.
