Thermometer in Fort Wayne, Indiana – where the temperature reached 106 Thursday afternoon, tying the hottest day ever. Many cities (Indianapolis, St. Louis, etc.) had their hottest day ever in June. This is the high temperature map from yesterday. By my count that’s 25 states that had at least one city in triple-digits. The hottest in the U.S. was Needles CA at 113. Notable temperatures in Michigan: 105 Ypsilanti, 103 Adrian, 102 Hillsdale, 100 Marshall, Coldwater and Flint. Battle Creek was 99, Kalamazoo peaked at 98 and so did Lansing (record). Grand Rapids stopped at 97, tying a record for the date. We did hit 97 last year on July 20th, part of a string of days from the 18th on that had highs of 92, 91, 95, 97, 96. It was much cooler by Lake Michigan where the high temperature on the beach at Muskegon was 73.4 (at 11 AM), Holland reached only 73.0 and the S. Haven lighthouse topped out at 77.1 at 6 PM. Other high temperatures of note: 111 Hill City KS, 108 St. Louis MO and Mt. Vernon IL, 107 Evansville IN and Little Rock AR, 106 Muncie and Terre Haute IN and Bowling Green KY, 105 Nashville TN, 104 Tupelo. Craig James sent me an email saying that the last time we made 100 in G.R. (July 1988) the average dewpoint that day was 54 (relatively dry). Today is another Clean Air Action Day. We should be dry during the day. Here’s the convective outlooks from SPC. Severe T-Storms may be rumbling just to our south the next three days and maybe up to I-96 on Saturday. Both the NAM and GFS give G.R. a high of 92 today (Fri.). The NAM has the highest chance of rain Friday night and the GFS on Sunday. The European would give G.R. .03″ of rain next Tuesday and .05″ on Thursday. It gives Kalamazoo .06″ on Saturday. The European has high temperatures in the low-mid 90s through next Thursday with next Wednesday the hottest (at least upper 90s). On the 500 mb map you can see the huge bubble of high heights stretching from Arizona to the East Coast. Looks like the ice is approaching half gone on Hudson Bay. Grand Rapids is +2.2 degrees above average for June so far. If you want to cool off, head to Lake Michigan..or…Mt. McKinley.
