Snowfall coated the area again today—the 5th consecutive day to put measurable snow on the books officially in the city. 0.2″ fell at O’Hare and 0.3″ at Midway—though we had local reports of up to an inch of snow in spots.
Monday marks the 4th consecutive day with NO OFFICIAL SUNSHINE. Frank Wachowski reports that last time a March recorded four straight days without sun was in 1989.
And there’s further evidence the same parade of storms which has lambasted the California is having an impact on Midwest weather is the lack of sun this month and the elevated precip tallies here. March has produced only 30% of its possible sun. A typical March produces 48%. So at least to date, Chicago has seen less than 2/3’s its typical March sunshine.
And 2023’s 7.58″ of water equivalent precip dwarfs the 4.89″ which is normal to date. In fact, it’s 155% (more than one an a half times normal).
Happily, clouds are due to break later tonight and sunshine stages a welcome comeback Tuesday. It won’t have an immediate effect on taps which are to average more than 11-deg below normal—not only today (Monday)—but Tuesday as well.
