Lake Michigan Warming Lower MichiganFebruary 11th, 2014 at 6:49 pm by Bill Steffen under Bill's Blog, Weather
This is the low temperature map from this morning. Click on the image to enlarge. These are the lows as of 7 am EST, which is before sunrise, so some weather stations would have been colder than the readings on this map. You can really see how Lake Michigan was warming Lower Michigan last night. With a west wind providing lake warming and lake-effect clouds, Grand Rapids had a low of +5°. Across Lake Michigan in Wisconsin, it was -17° at Green Bay and -12° at Kenosha. Wisconsin’s coldest was -29° at Land ‘O Lakes. In NE Illinois, the temperature dropped to -10° at the Chicago Botanic Gardens just north of Chicago. Rockford bottomed out at -21°, breaking a daily record by 9 degrees. It was also -21° at Kankakee and -20° at Joliet. Farther west, the low was -22° in Moline IL and a frigid -24° at Waterloo, Iowa. There were double-digit below zero temperatures in Central Illinois at Lincoln (-16°), Peoria (-13°) and Springfield (-13°). The coldest reading in Illinois was -26° at both Rochelle and Watseka. Indiana was shiverin’ this morning, with lows of -17° at Lafayette and -16° at Fort Wayne (breaking the daily low temperature record by 10 degrees). Detroit with the clouds and west wind was 26 degrees warmer than Fort Wayne. It was also cold in northern Lower Michigan, where Lake Superior and northern Lake Michigan are 95% frozen over. Copper Harbor at the tip of the Keewenaw Peninsula bottomed out at -11° and Marquette reached -23°, the coldest reading in 10 years. In Northern Lower Michigan, Gaylord dipped to -22° and Pellston reached -26°. So, thank you Lake Michigan for releasing a bit of that stored warmth from last summer and making the early morning here in West Michigan a little less frigid.
