I know there has been a lot of talk as to how a El Nino vs a La Nina affects the winter temperatures and snow fall totals. Well I took a quick look to see how past El Nino and La Nina’s had on the seasonal snow fall totals at Grand Rapids, MI. What I came up with kind of surprised me. First lest look a La Nina years. Since 1950 there have been a reported 11 winter seasons with a weak La Nina in Grand Rapids in these 11 winters the average snow fall has been 76.3” with a range of 104.9” to 60.1” there have been a reported 4 moderated La Nina winters the average for those winters is 77.8” with a range of 101.6” to 51.2” there has been a reported 7 strong La Nina winters and the average for them is just 69.5” with a range of 107.0 to 51.2”
On the El Nino side since 1950 there has been a reported 10 winters with a weak El Nino the average snow fall for the 10 years is 74.4” with a range of 104.7” to 39.7” for the winters with a moderate El Nino there have been a reported 7 winter seasons the average for moderate El Nino winters at GRR is 76.7” with a range of 132.0 to 47.6” as for the winters with a strong El Nino there has been a reported 5 winter seasons with a average of 70.9” and a range of 87.8 to 64.2” and for El Nino there is a “very strong” category and there are 3 winters in that list and the average at GRR for the 3 winters is 52.2” with a range of 61.1 to 35.9”
The average snow fall for GRR for the 68 years period from 1949/50 to 2017/18 is 75.9” with a range of 132.0 to 35.9” So the bottom line winter average is weak La Nina 76.3” moderate La Nina 77.8” Strong La Nina 69.5” Weak El Nino 74.4” moderate El Nino 76.7” strong El Nino 70.9” very strong El Nino (only 3 winters) 52.2” all winter since 1949/50 75.9”

With September being the 13th warmest on record here in Grand Rapids and Lansing and the 6th warmest on record at Muskegon and for the year Grand Rapids now has had 7 of the first 9 months warmer then average. One has to wonder when this trend will end? Will it be sometime in the upcoming winter season? Most on the long range guesses continue to point toward a continued warmer than average pattern. But I would think that sometime this pattern will change (I would think)
We were in eastern New York last week. While the color there is behind where is should be for this time of year it is still ahead of what we have here in west Michigan. In fact parts of eastern Michigan have more color then we have. So with the rain and mild temperatures it looks like this may be a dull color season here in west Michigan.
Slim
Major pattern change is coming! Heat and humidity will be a thing of the past and below normal temps will rule baby!
Well I’d love to believe that, problem is you’ve been saying this same thing for years, and our pattern hasn’t changed in years. Maybe someday it happens, or maybe it just keeps getting hotter and eventually we’ll all just melt into a primordial soup.
70 dew point again?? I keep thinking we have to be done with these outrageously high dew points, and then more humidity rolls in again.
Good job Slim! Must take forever to look up all those #’s!
Not a good day to have MSU or Mich tix.
I stand corrected.
BREAKING NEWS>>>>>>get ready for a MAJOR pattern change!!! Tons of below normal temps will be arriving by weeks end and last for many many weeks!!! Bring it!
Lol!! Too funny!
