2005’s warmest temps to date headed this way

|

Significantly higher temperatures lie ahead, and that’s hopeful news for area residents anxious for summer warmth after a May that averaged 1.6º below normal.
Computer models are in general agreement that a major weather pattern change is in the works. For Chicago and the Midwest, it means a gradual transition from a regime of near or below normal temperatures to one of temperature surpluses.
To date, Chicago has logged only five days with temperatures in the 80s, but that number is likely to double within only the span of the next week. It will come as no surprise to residents within a mile or two of Lake Michigan that they will feel an abridged version of the warming.
Frequent afternoon breezes off the still-chilly lake waters will restrict lakeside temperatures.
