Monday PM, Grand Rapids climbed to 90° for the 15th time this summer. That compares to just 11 days all last summer. The most 90° days in G.R. in recent decades was 37 in 1988. 2012 came close with 32 days of 90-degree heat, including a blistering 104° on July 6, 2012 – the warmest temperature G.R. has had since 1936. We did not have a 90-degree day in 1951 and in 2014.
Cooler and much less humid air has moved back into West Michigan. We’ll see highs in the upper 70s to near 80 for today and Wednesday with much lower humidity. We have a good chance of scattered showers and thundershowers next weekend, but no rain is expected through Thursday.
Here’s high temps. Sunday. Grand Rapids was warmer than Miami, Tampa, and Tucson AZ. The 93° at Moosinee on James Bay in Canada is impressive. In Northern Michigan, S. Ste. Marie reached 92°, Iron Mt. was 91° and even Munising along the Lake Superior shore made 90°. Manistique had a high temperature of just 72°. They had a south wind coming down the length of Lake Michigan.
