Just like it says in the 1985 song recorded by Glenn Frey, "the Heat is On" across the center of the nation. A late summer push of hot and moderately humid air continues to expand under a high pressure ridge aloft. The graphic from the Chicago Tribune shows the extent of the heat, and some of the forecast high temperatures in the Midwest. The basic upper air pattern producing the heat over the center of the nation will last into the upcoming holiday weekend
As the graphic shows, while it will be hot in the Chicago metro area through the weekend, it is not unprecedented. The string of heat that covered the city in 1953 is truly amazing. It would be impressive for the city in any stretch of summer, never mind it occurred so late in the summer season. A string of such heat is something that would be more natural to occur in late June through late July, not late August. The normal high for the city is now down to 81 and gradually falling.
The current heat wave over the city will not last anywhere near the 1953 data. Highs today and Tuesday will be in the 90s. A weak cold front will then sag down over the area Tuesday night with the chance of storms. Much better storm chances will be northeast from Minnesota into Ohio through Wednesday evening. Highs Wednesday through Friday will be in the mid to upper 80s before the low 90s appear again for the Labor Day holiday weekend.
