April 2013 rain tally running 31 times last year's total; the month ranks 20th- wettest of the past 142 years!

With deadly tornadoes in the Deep South Thursday, tree-downing ice to our west  in Sioux Falls, South Dakota Wednesday and a record 30-inch snow tally in sections of the Plains Tuesday, Chicago’s March-level temperatures, clouds and drenching rains of recent days seem to pale in severity by comparison. Having said that, Chicago’s weather of late has been no picnic.

Since April 1, rainfall totaling  1.85″ has fallen at O’Hare.  The amount is 31 times that which fell here during the same period a year ago. The tally places this month as the 20th wettest April to-date in 142 years of Chicago weather records.

 

Friday to see a third day with temps more typical of March; 76% of spring days here have posted temp deficits

 

Chilly temperatures have dominated here since meteorological spring got underway on March 1. 32 of the season’s 42 opening days —74% of them—have produced a temperature deficit.

81% of March days and 64% of those in April have been below normal.

Clouds have slashed month’s sun tally here by nearly 60%

 

 

The clouds and precipitation of recent days have played havoc with Chicago’s April sunshine tally. While 91% of the month’s possible sun was on the books just a week ago, that tally has slipped to 54% of normal in just the past 24 hours.

Brief temp rebound could include Sunday/Monday 60s

 

While model forecasts hint at cool readings Friday and Saturday, significant but temporary warming appears a good bet later in the coming weekend. The area could be in line for back-to-back 60s on Sunday and Monday, though another wet storm system takes aim on the region mid-week and could return chilly temperatures to this area with winds off the lake.
