Finally, a surge of mild air predicted to interrupt April's chilliest open in the past 20 years


It’s been too long coming for many in the Chicago area.  Temperatures Thursday afternoon are to make a welcome move on 60-degrees in the midst of the coldest April open here in 20 years.


The month has run 9-degrees below normal and nearly 20-degrees behind the same period a year ago in its opening three days.


Wednesday’s easterly winds off Lake Michigan waters running 10-degrees colder than at this time a year ago—41-degrees this year versus 2012′s 51 reading— limited highs to 44 at O’Hare, 43 at Midway and just 39-degrees at the lakefront—each reading well off the 54-degree normal for the date.


A 60-degree high Thursday would only be the year’s 2nd; 23 were on the books by this time last year


Thursday’s mild surge—the first and least significant of two predicted here into the coming weekend won’t last long. A wind-shifting cold front passes Thursday night ushering northeast winds back into the Chicago area—a flow which is to landfall here Friday after a trek off chilly lake waters.


A 60-degree high Thursday would only be 2013’s second to date.  By comparison, 23 had occurred by this date a year ago.


Saturday’s predicted 67 would be city’s warmest in 18 weeks

The area has a shot at even warmer air Saturday. That’s when a gusty south to southwest flow is to take up residence for a day—a move expected to push temperatures here well into the 60s.



The 67-degree high being predicted Saturday would be the city’s warmest daytime reading since a 70 back on Dec. 3—18 weeks ago.



No shortage of sun so far this month; April’s opening 3 days the sunniest of any April 1-3 in 9 years



April’s chill has occurred despite plentiful sunshine!  The month’s opening three days have logged 91% of of their possible sun—-52% is considered normal in April. Not since 2004 has 91% of early April’s possible sun bathed the Chicago area.



Stormy pattern setting up next week; big rain totals suggested by suite of computer models



The stage is set for multi-day rains next week yielding some BIG predicted rainfall numbers. As much as 1-2 inches of rain may fall in the coming 7 days.



A wave of rainfall is indicated Sunday night and Monday morning, possibly easing to lighter, more sporadic sprinkles Monday afternoon in time for the Cubs Home Opener at Wrigley Field. But the heaviest rains of all—rains which could include embedded thunderstorms amid cool, gusty and raw easterly winds over the northern half of the metro area—are predicted in the Tuesday/Wednesday time frame.
