For the first time in two weeks, Canada is the source of Chicago’s weather on Wednesday. It’s a change which has been driven by a sharp realignment in steering winds aloft. It brings to an end one of the most prolific sets of early season 80° days on record here. Only two other years in more than a century of weather records (1973, 1984) have the opening two weeks of June hosted 12 days with 80s. The month’s opening 14 days are running 8.4° above normal, enough to rank it among the top ten warmest Junes on the books here.
Nine days this month have already exceeded 85-degrees, a tally which wasn’t reached until August 2 last summer.
Summer’s official open is only seven days away. The new season arrives at 1:46 a.m. next Tuesday, June 21 at the point the sun’s most direct rays fall as far north of the equator as at any time of the year.
WGN-TV Chief Meteorologist Tom Skilling and the WGN Weather Center staff provide daily coverage of weather in the Chicago area.
