With a title like that, you’re probably thinking I’m writing about Max Scherzer and what his record will be in a week. I hope that’s right. Actually, I’m comparing the number of 90-degree days thru July 6 in Grand Rapids in 2012 and 2013. Last year, July 6th was not only the 15th 90-degree day of the year, it was also the warmest day that Grand Rapids had since 1936. Click here to read about the heat wave of ’36 – the hottest weather Michigan (and over much of the Midwest east of the Rockies) has ever had. The thermometer hit 104 in G.R. last year on 7/6. Other high temperatures that day: 104 Kalamazoo, 103 Battle Creek, Lansing and Coldwater, 102 Regional Airport in Holland and Three Rivers, 101 Hudsonville, Rockford and GVSU in downtown G.R., 100 at WOOD (Heritage Hill), Calvin College, Sturgis, Jackson and Allendale, 99 at the Muskegon Airport, 98 Boatwerks on Lake Macatawa and at GVSU in Muskegon, 93 Grand Haven, 86 on the beach at Muskegon. Another interesting aspect to the heat of July 6, 2012 was the lack of wind. Here’s the average wind speed midnight-midnight on July 6, 2012: Grand Rapids 4.7 mph, Muskegon 3.8 mph, Kalamazoo 3.7 mph, Holland 3.0 mph and Lansing 2.5 mph. On the day with the hottest temperatures since 1936, with the air conditions running on max and near-record electricity need, the wind turbines were the winners of American Idle. Wind turbines are and will be a part of our energy future, but there are times when the wind isn’t blowin’ and the sun isn’t shinin’. Finally, I have the 6-10 day temperature outlook on the right. It’s got us in the light blue, showing a little better chance of (slightly) below average temperatures from July 11 – 15. We are currently at our highest average temperatures (hi 83, lo 62). As of today, we have lost 8 minutes of daylight since the Solstice back on 6/21.
