Lake Michigan’s shoreline water temperature broke above 70° for the first time in 2007 Thursday. But it was the area’s hot inland temperatures which made news. Readings from Plainfield to Geneva, DeKalb and Algonquin soared into the mid 90s making it the hottest day of the year at many inland locations.
Warming lake waters this time of year limit the degree and scope of the cooling which sweeps ashore when winds blow from the east. Rather than sending readings into free fall, as might have happened a month or two ago, winds off the lake act to more modestly air condition areas closest to Lake Michigan’s waters. As a result, Northerly Island’s temperature topped out at 77° Friday while temperatures hit 96° at the WeatherBug temp sensor in southwest suburban Plainfield.
