Chicago's record-shattering run of above-normal temperatures ended yesterday:
The abnormal, all-too-often record warmth, couldn't continue indefinitely. For 26 consecutive days, Chicagoans were treated to temperature levels which would have been at home in June and July. They were without precedent in March and early April.
The impact of that warmth continues, even in the midst of noticeably cooler air here. And while Easter weekend temperatures are expected to rebound to the 60s, an even cooler air mass seems determined to settle southward over the eastern half of the country next week.
April's opening 5-days continue to run 3°C warmer than the same period a year ago. The results of the abnormal warmth have been tangible. Vegetation in and around Chicago has bloomed 4 to 6 weeks early, a trend which has already spawned an extremely challenging pollen-season through which many continue to suffer.
Thursday marked the first day in 27 in which temperatures finished "below normal".
Next week it's supposed to be "seasonal," which could include a freeze.
