In my opinion May is the nicest of the spring months and on average along with September are the best months weather wise in west Michigan (September is the better of the two IMO) May like the other spring months can have big day to day and year to year swings in both precipitation and temperatures. For example, the hottest day in May was a very hot 95° on May 31st 1934 to a crisp cold low of 21° on May 1st 1903. The average high starts out at 65° and works its way up to 74° by the end of the months and the average low starts out at 43° and is up to 53° by the end. The mean temperature for May at Grand Rapids is 58.7° the warmest mean temperature for May was 65.7° in 1977 and the coldest mean temperature for May was twenty years later with a cool 50.3° in 1997. (the average mean for April is 48.3° so 1997 was a cold May) The average amount of precipitation for May is 3.98” with the most 10.01” falling in 2001 and the driest May was in 1936 when only 0.72” fell. On average May receives less than a trace of snow but in May of 1923 Grand Rapids (and much of lower Michigan) had a true snowstorm and here in Grand Rapids we recorded a almost unbelievable 5.5” of snow. All falling on May 9th 1923 (some other snow fall reports for May 9th 1923 Flint 12” Lansing 11.5” Saginaw 9” Muskegon 5”) In May of 1902 grand Rapids also had 5.5” of snow. That year the snow fell on May 10th In 1929 Grand Rapids had 3.0” of snow in May in that year the May snow storm was on May 2nd The last time Grand Rapids had over one inch of snow in May happened in 1954 when 2.0” of snow fell. In May of 1954 the snow fell on May 3, 4 and 5th the last year where GR had more than a trace of snow was in 1990 when 0.2” fell on May 10th The most sun shine for May happened in 1958 with 84.5% and in May of 1973 Grand Rapids had a November like total sun shine amount of only 28.2% the highest reported wind gust for May happened on May 5th 1950 with a reported gust of 79 MPH. Last May was the 4th warmest May in Grand Rapids recorded history. The last 10 days were all 80° or warmer and the last 6 days seen highs of 85, 86, 87, 93, 93 and 94. A rare may heat wave.

This evening while eating dinner some of the biggest snowflakes started falling. After dinner we went grocery shopping and the car had snow accumulating on it when we headed home. Earlier today we had headed over to a greenhouse by our house just to walk and see all the pretty flowers. It was beautiful in there. I see the snow will be gone and the sun will shine by morning. 🙂
Nice!! Sunny and about 10 degrees warmer tomorrow!! I’ll be grillin and chillin!!! INDY break out those Sprites tomorrow!!

Golfing here I come! Hard to believe that Kent is still in a wwa!
I don’t get it either Rocky?? There’s nothing going on all night tonight?? It’s a joke!!
I will be ready Andy I’m tired of this cold ..Bring on May yeaaaa! INDY!
Heck yeah INDY!! Get the warm weather ROCKIN! Not too warm though!
I’m loving the wall that Lake Michigan has put up for us tonight to keep that disgusting awfulness out of our area!!

Still waiting for that snow Rocky was talking about!! Gonna be real hard to get to his 6 inch prediction if it doesn’t start soon!
Get ready for a long stretch of below normal temps! Nice warm Spring temps – forget about it until at least mid May!
The 60’s are perfect!! At least there won’t be any trash snow!!
You have very low standards if you like temps in the 50’s to around 60 with clouds and off and on showers and rain, especially for the month of May when we should be seeing mid to upper 60’s and plenty of sun!
Ehh…I’m just happy when I can do stuff outside without putting on 14 layers of clothes, so 60’s are fine with me!
I was hoping to snowshoe on Sunday morning, but it looks like the good accumulating snow has moved to the south. I may actually end up golfing on Sunday afternoon instead of golfing! Who knew?
Put the snowshoes away til December!! Nobody wants that garbage this time of year!
Temps running some 20* degrees below normal crazzy …INDY!
Yes the cold pattern of 2019 continues!
Eh…temp was 18 degrees below normal today, it was about 18 degrees above normal on Monday. It all averages out! Typical spring!
Look at the stats and the facts! Temp in GR are below normal in 2019 and no change in sight!
Interesting read! Thanks for all the May weather stats!
Slim is the King of stats!
Ahhhh…Winter in the Southern Arctic. It never truly “lifts” until well into June. Hoping everybody made the most of last week’s “summer day”…at least we can’t say summer did’nt arrive this year. Hold fast to your roof rakes and shovels! Winter coats for July 4th celebrations will be our special uniforms.
I still hope to be snowshouing in May!
Im ok with not getting any snow now but I’m upset with the next 10 days or so the warmest temperature I see is 60* degrees we are getting into May now that’s cool for this time of year ….Our Cool Spring continues …INDY!
Poor Rocky, if that storm had moved north overnight, he would have already had 85 posts by now this morning in this blog entry, but his silence is telling!!
…Added the new live webcam to its own page – moved the Skywarn, Tornadoes and Storms to sub menus under MiReady menu.
Thank you for all the resources Michael, this blog just keeps getting better & better!!
Check out this bad boy! Slightly under the 6” that Rocky and his predictions were calling for yesterday in Northern Kent!!
We will have to wait and see even that may be over done. It is hard to get snow to acculamate this time of the year.
Slim
Good point Slim! No more snow!! IT’S SPRING!
Just the snow maps not my predictions! Get real or don’t bother commenting!
