Is GR Getting warmer???

posted in: Michigan Weather Forecast, Slim | 20

There has been much talk as to how warm this summer has been. So this week I will take a look and see if there is some kind of trend. Here is what I have found out. In looking at Grand Rapids recorded history. In going back to 1897 (yes, the records go back to 1892 but there are a lot of missing months in the time between 1892 and 1896) but in the time between 1897 to 2017 a total of 7 of the top 15 warmest years have happened since 2000. And if you flip that over there are no years since 2000 in the top coldest years. The most recent of the top coldest years is 1996 and that came in at the 13th coldest. Here is the complete list of the top 15 warmest years in Grand Rapids recorded history.
1. 2012 mean 52.8°
2. 1931 mean 52.2
3. 1921 mean 52.2
4. 1998 mean 51.5
5. 2016 mean 51.2
6. 2010 mean 51.1
7. 1938 mean 50.9
8. 1939 mean 50.5
9. 2017 mean 50.2
10. 2007 mean 50.2
11. 2006 mean 50.2
12. 1922 mean 50.0
13. 2011 mean 49.9
14. 1987 mean 49.9
15. 1953 mean 49.9°
The top 15 coldest year (since 1897)
1. 1917 44.6
2. 1904 45.2
3. 1978 45.6
4. 1972 45.6
5. 1943 45.7
6. 1969 45.8
7. 1989 45.9
8. 1974 46.0
9. 1924 46.0
10. 1907 46.0
11. 1950 46.1
12. 1912 46.1
13. 1996 46.3
14. 1976 46.4
15. 1924 46.5
Through July 2018 the mean for the year is 48.3°
Of the warmest 15 years since 2000 only 2012 had a high of over 100 and is the only year that is in the top 15 in the number of 90° days. So the years that were warm in the 2000’s did it with out a lot of extreme summer time heat. Note the year with the 15th most 90 days is 1941 with 23. 2018 is now at 18 and in 30th place.

It has been a very warm August by Michigan standards so far. Here are some mean temperatures and the departures as of Thursday August 24th Grand Rapids 74.3° +2.9°, Muskegon 74.1° +3.6°, Lansing 73.6° +3.3°, Detroit 75.9° +3.4°, Flint 72.2° +2.9°, Saginaw 73.2° +3.9°, Alpena 71.4° +5.4°, Sault 69.6° +4.4° Marquette 65.2° +0.9° Of course not too far to our south it has been much warmer but that in normal. Indianapolis 75.4° but the departure is only +0.8° Bowling Green KY 78.6° and their departure is just +0.6° and they have had 9 days of 90 or better and 8 more days in the upper 80’s.  On the flip side of the coin Fairbanks AK the mean so far is 56.9° that is good for a departure of -0.4° The warmest so far this month is just 72 and the lowest is 41.  and way up at Barrow AK their mean so far this month is 37.3° the warmest it has gotten there is 48 and the coldest is 30 and they have had snow on several days

So 8 out of the warmest 15 years recorded have been since 1998. And there is very little representation from the 50’s, 60’s, 70’s, and 80’s on the warmest list. I for one am skeptical for good reasons of readings taken in the 1930’s and earlier. All in all, definitely getting much warmer.

Awesome job again Slim! So the stats indicate we are getting warmer, time to move to The Colorado mountains. Ha, I wish.

Big day for us. Our second child, and oldest son, gets married today! Hoping the rain stays away later today as we have a big party here tonight.
