Through yesterday, KGRR Michigan precipitation is 7.03 inches above normal for 2026 year to date

 Wish the rest of you could have some of it. Our rivers are flooding.

 

 

Monthly mean average temperature in Grand Rapids, Michigan has been below normal for three consecutive months

 

Actual monthly mean average temperature in Grand Rapids vs. average monthly mean since 1892:

November 2025: 38.7 F vs. 39.1

December 2025: 26.0 F vs. 28.5

January 2026: 20.2 F vs. 23.8

Totals: 84.9 vs. 91.4 = -6.5 degrees F or 7.1% colder.

 

On an annual basis just a handful of years since 1999 have been at or lower than average temperature of 48.1 F:

2000 48.1

2003 46.8

2009 48.0

2014 46.5.

 

 

Snowfall in 2025-2026 to date:

 

66.2 inches vs. 41.6 normal to date. Annual mean = 66.8 inches. 

Trend for lowest minimum temperature in Grand Rapids, MI 1896-2024

The trend is colder by almost 2 degrees F for lowest minimum temperature over 129 years at KGRR. 

This chart shows, like the charts for heating degree days or average temperature discussed earlier, the boat anchor for temperature which is 1943-1997. The anchor is heavy enough to keep the mean minimum since 1963 lower than before it, at -9F vs. -6F, despite all the recent warming.

Mean lowest minimum temperature:

1896-1943: -5F (48yrs)

1943-1997: -10F (55yrs)

1997-2024 to date: -5F (28yrs).

 

Trend for annual precipitation in Grand Rapids, Michigan 1903-2023

 Wetter!

The long term trend for the Oceanic Nino Index is thought to be predictive of this wetter outcome in the Upper Midwest. The index trend is cooler from about +1 degree F anomaly to -1 degree F anomaly since 1951.

Mean annual precipitation at KGRR has risen from 31.88 inches 1903-1951 to 36.81 inches 1951-2023.

 

 

What complete rot: Drudge's heat index map for 6PM EST shows 92 for Lake Michigan when it's 78 in Grand Rapids

All you need to know about the hottest day ever

 Tuesday’s global average temperature was calculated by a model . . . to estimate daily average temperatures starting in 1979.

“This is our ‘best guess’ of what the surface temperature at each point on earth was yesterday,” [Paolo Ceppi] said.

 

WaPo, of course. 

Meanwhile, back in the real world of actual measurement, the highest maximum at KGRR so far in 2023 was 91 degrees F, on three days in June.

And the hottest 4th of July was way back in 1911. Yesterday made it to 89.

Maximum temperature observed has been in decline here for decades.

 

 

Trend for average temperature in Grand Rapids, Michigan shows an anomaly of less than +0.5 degrees F after 124 years

 Could be just a heat island effect from KGRR.

KGRR climate update through Nov 2022

2022 mean average temperature eleven months through Nov = 50.4

Mean average temperature through Nov since 1892 = 50.0

28 inches of snow, second highest November on record, all melted now.

 

 

Buffalo, New York gets all the headlines, but Grand Rapids, Michigan has already had its second snowiest November ever

 We've been busy around here with three days in a row of 7+ inches of snow each, and in excess of two feet in five days.

Total November snow is already at 27.3 inches, which beats November 1951 at 26.9.

The snowiest November of all time at KGRR was November 2014 with 31 inches.

It was 75 degrees F here in Grand Rapids on November 10.

We dropped to 18 F last night.

Record November snow in Buffalo was 45.6 inches in November 2000. The second snowiest November was 31.3 inches in November 1976.

BUF is officially at 36.9 inches already through the 19th, also making November 2022 its second snowiest November ever, with ten more days left in the month. 

Its three-day history is 9.4, 5.7, and 21.5 inches yesterday.

It was 79 F in Buffalo on the 5th, and dropped to 23 F in Buffalo last night.

How is it that the National Weather Service at Grand Rapids, Michigan, station KGRR, can't get the high or the low temperature right for July 19, 2022?

 The three day history for KGRR shows that the high on the 19th was 88 degrees F at numerous points throughout the afternoon and evening, and that the low was 71 degrees F early in the morning, but if you look at the daily data for a month it says the high was 90 degrees F and the low was . . . 49 degrees F.

The mean minimum for July going back to 1892 is 49 degrees F, so that explains that error. Some idiot transcribed that value instead of the actual value. So far this month, the lowest minimum was 52 degrees F.

Can't explain the 2 degree F discrepancy for the high, though. You would think that there would be room for a spike up to 90 during an hour interval by the presence of at least one 89 value at some regular hourly interval, but there isn't one.

Is someone's fat finger on the scale over there?

It's a good reminder that the human element introduces error into the record, whether intentional or not, and that you can't believe everything you're told, even about the simplest of things.

By the way, I'm just four miles from the station as the crow flies, and we had a rain shower last night which doesn't show up in the three day history either.

Average temperature in 2021 in Grand Rapids, Michigan, was the eighth highest on record in 124 years

The trend line after 123 years of data shows average temperature in Grand Rapids, Michigan, rising 0.7 degrees F, or 0.388 degrees C, 65% less than the 1.1 degrees C claimed for the world by the United Nations Intergovernmental Panel on Climate Change yesterday.

And the minimal warming in Grand Rapids may in fact be misleading. Five of the data points in those top eight are from the last twenty-five years, during which increasing development around the KGRR measuring station may well be contributing heat island effects.

 

 

Station KGRR of the National Weather Service is increasingly unreliable

Yesterday's predicted high was 50 degrees F. 

It made it to 38.5 on my device not far from the airport right around 5PM last night. I only cared about it because I was earnestly expecting the warm temperatures to make it easier on me while I pumped some standing water from a low spot on my property.

The National Weather Service 3-day history shows the high was 39 degrees F, right at about that time. It is customary for the NWS to round up to the next degree once the value hits .5.

But both the Daily Almanac and the Climatology pages show the high was 40 F.

Looks like lying and bias in favor of global warming to me, on top of not being able to predict the damn weather tomorrow.

 

When people lie about everything in a society, even the smallest details, that society is finished because without trust there can be no society.

Warmer conditions for KGRR in calendar 2021 were an instance more of moderate winter conditions back-ending and front-loading the year than of extreme summer conditions in the middle of it.
