While it may be the unofficial end to the summer season, it sure as heck felt like summer today - afternoon highs climbed to their highest point in nearly a week and a half; today's high of 88° was 3° above average for September 7th. Worse yet, things are about to get even hotter. A complex of higher pressure camped out over the southeastern quarter of the country has stalled a front out across portions of Central and Northern Illinois and Indiana. Until that front passes to our south, we're stuck with the summer-like temperatures.
Highs will routinely reach the upper 80s and low 90s across the Tri-State over the next 72 to 96 hours; Tuesday and Wednesday will bring about our hottest weather in two weeks. Fortunately, the humidity won't necessarily be oppressive, though it will feel quite sticky at times - dew points will remain in the mid to upper 60s. We'll reach 90° on Tuesday, 91° on Wednesday and 87° on Thursday before that aforementioned front passes through late Thursday night into early Friday. If there's any silver lining here, it's that despite the passing frontal boundary, conditions will remain dry through the remainder of the work week.
Friday looks as though it will be clear and much cooler - 82° and mostly sunny to be exact. Another passing front on Saturday however, will indeed generate some scattered rainfall, though Sunday still looks dry with afternoon highs around the 80° mark. After what was simply a spectacular weekend, we find ourselves once again looking ahead to the weekend for more than a break from the everyday hustle bustle of the work week. Stay Cool.
