Two weeks ago Al Gore was in Chicago doing his routine on climate change during which he says that by the middle of the century it'll be warm enough to play baseball in February. For the record, yesterday was the chilliest Cubs home opener in five years.

And Chicago weather guru Tom Skilling says the chills of April will continue:

Chicagoans brace for early March level temperatures Tuesday, with readings more than 15 degrees below normal, as the area moves into an 11th consecutive day of sub-normal temperatures. This month's 41.0-degree average temperature is 3.6-degrees below the long-term 138-year average—cool enough to rank among the chilliest 20 percent of April 1-14 periods on the books. It's the first April here in 25 years that has failed to host a single 60-degree daytime high.
