First and Lasts

As we are now past the half way mark of September 2020 I thought it would be a good time to take a look as some upcoming first and last events.  The average last 90° day at Grand Rapids is August 23rd the earliest last one was on June 10, 2000 the latest was on September 29, 1953. 1951 and 2014 did NOT have a day officially reach 90 at Grand Rapids. Last year the last day was July 20th and this year GR had 16 days of 90 or better with the last one on August 26th The average last 85° day is September 14th the earliest was on August 12, 1989 and the latest was on October 21, 1953. Last year the last one was on September 21st The average last 80° day at Grand Rapids is September 30th the earliest was on August 28, 1918 the latest was on November 1, 1950 Last year it was on September 30th The average last 75° day at GR is October 13th the earliest was September 15, 1981 the Latest was on November 6, 1975 Last year it was on October 1st The average last 70 day is October 24th the earliest was October 1st 1925 and the latest was November 23, 1931 last year to was on October 10th

The 1st 32° low that will signal the end of the growing season. Before I get to that I will remind everyone that the last 32° low last spring was on May 13th and while there was a green up Grand Rapids also had lows of 26 on May 9th and lows of 29 on the 8th and 12th So the official start of the 2020 growing season was on May 14th  At Grand Rapids the average first low of 32 is on October 13th The earliest was September3, 1946. The Latest was November 14, 1918. Last year it was on October 18th  For a killing frost of 28 the average is October 28th The earliest was on September 23, 1974 and the latest was on November 29, 1948 Last year it was on November 5th

For a hard freeze of 25 the average is November 8th the earliest was on October 3, 1974. The latest was on December 23, 2001 (talk about late) Last year it was on November 6th

And for snow fall. The average that the first 1” snow fall occurs on is November 19th the earliest 1” snow fall was on October 12, 2006 the latest was on December 23, 2011. Last year it was on November 11th

For a 3” snow fall the average first one is on December 5th the earliest one was on October 19, 1989 the latest was on March 16, 1949 Last year it was on November 11th when 5.5” of snow fell.

This past week we had a lot of high-level smoke and that made the sky look a pale milky white on several days. It more than likely also held the daytime temperature down.

It went down to 38 here last night. The house feels pretty chilly in the house this morning. It is so nice to see the sun it helps warm it up some. It’s a great day to cut back some of my flowers that are done for the season.

The smell of fall in the air. I like it when the trees just start to turn. Great time of the year !

33 here with our first frost of the season. To me, the first frost is the official end of summer – although I’m wearing shorts getting ready to hit Meijer for groceries. Speaking of summer, this was one of the best ones I can remember, IMO. It was never cool and tons and tons of sunshine. Could have used some more precip, but that’s my only complaint. Have a great day all!
