It’s not rare to see 70s in Chicago by April 12—in fact, it’s happened in 3 of 4 years since records began in 1871.
Friday’s high was the first of 2014 to reach 70, coming 18 days beyond March 24 which has been the average date for the city’s first 70 of the season.
Saturday’s powerful southerly winds, sweeping up the eastern flank of the country’s latest spring storm, are to propel afternoon readings even higher—reaching 76-degrees.
With a 68-degree high to follow Sunday, this weekend’s daytime temps are to be the warmest of any Saturday/Sunday period since the 80 and 64-degree highs on Saturday and Sunday, October 5-6—more than 6 months ago.
Saturday’s June-level temps are to beat last year’s 45 on this date by 31-degrees
If the 76-degree high predicted Saturday afternoon verifies, it will be 18-degrees above normal and, even more impressively, 31-degrees warmer than last April 12’s 45-degree max temp.
The set of back to back 70s Friday and Saturday come 18 days earlier than a year ago
Friday’s 70-degree high and the predicted 76-degree peak reading Saturday are to be the first back to back 70-degree or higher temperatures of 2014. These consecutive 70s arrive 18 days earlier than the first two 70s appeared on the scene a year ago. Impressive rainfall numbers coming out of computer models; thundery downpours could produce 2”+ totals—the biggest in 10 months
The waves of thundery downpours likely to sweep the area later Saturday into Sunday night—then end as cold rain Monday morning amid markedly lower temperatures and strong northerly winds, may end up this area’s heaviest rain producers since last June. A suite (collection) of computer forecast models are producing 2”+ cumulative rainfall totals–with harder hit locations potentially logging some 3+” totals.
