Tuesday marked the 11th consecutive day of below normal temps. Temps only reached 54 at O’Hare amid 30+ mph wind gusts and with just 18% of our possible sun.

But, big changes are coming and warming will result.

Temps surge to the low 60s inland Wednesday (the lakefront will stay in the 50s); the mid 60s Thursday and low 70s Friday.

Even warmer air is on tap next week with temps likely to flirt with 80-deg by Tuesday and Wednesday.

Lake breezes in coming days will produce cooling typical of this time of year along Lake Michigan. And the easterly flow will become better organized over the weekend. But east winds will become more southeast Sunday meaning the inland penetration of cool air will be present—but less pronounced then.

Temps this week, with the milder readings expected in coming days, are likely to average almost 5-deg milder than last week. But next week’s average temp is to surge nearly 15-deg warmer than this week—and that should be quite noticeable.

May is a month of more frequent warmth. But lake water warm far more slowly which makes it a month of frequent cooling lake breezes too. Still, the past 8 decades have produced 80-deg temps on one or more days in 99% of years; an 85 degree temp in 95% of year and a 90-deg temp has even occurred in 78% of years. IN fact, just 9 days from today’s date—on May 12th last year—the city recorded its first 90 degrees temp. Such warmth comes and goes until we get the lake warmer—but there temp progress in the cards for those awaiting warmer temps.
