Welcome to November

posted in: Michigan Weather Forecast, Slim | 9

Before we get into some information on November here is a brief summery of October 2019 at Grand Rapids. The mean was 50.2° that is a departure of -0.8° The high for the month was 77 set on the first and the low was for October a mild 31 set on the 26th There was 7.13” of rain and snow fall that is a departure of +3.87” as for snow fall a 0.3” was reported at GRR that is a departure of -0.2” There were 3 thunderstorms reported during the month. It ended up being a rather cloudy month as there was only 35% of possible sunshine.


Now for the month of November. During this month the average high/low starts out at 54/37 and ends the month at 40/28° Grand Rapids will lose 1 hour and 1 minute going from 10 hours 18 minutes on the 1st to 9 hours 17 minutes on the 30th The average November will see 3.51” of rain fall. The wettest was 7.90” in 2003 and the driest was 1904 when only 0.4” was reported. The average snow fall is 6.8” the most snow fell in 2014 when 31.0” fell. In 1906 and 1907 no snow fall was reported. The average mean temperature is 40.1° the record high was 81° on November 1st 1950 and believe it or not the record low was -10° on November 25th 1950 it looks like just before midnight the low reached -9 on the 24th It can and has gotten into the 70’s in November (I mention this just in case we do get into the 70’s and we know how Mookie will react to that if it happens) over the years it has gotten 70 or better in 36 Novembers. The most days over 70 are 4 in both 2005 and 2015 and in 2016 it reached 70 or better 2 times. And the odds of it reaching 60 or better are very good as only 10 years since 1894 has it not gotten to at least 60. In fact in 1975 14 days reached 60 or better in November and in 2012 the number was 12. The last time no days reached 60 or better was just last year with a high for the month of just 52 on November 4th The mean last November was just 34.6° and that was a departure of -5.5° and good for the 10th coldest November on record at GRR. as stated the high for the month was 52 on the 4th and the low for the month was 20 on the 22nd There was 14.4” of snow fall That was good for the 15th snowiest November at Grand Rapids.

Here the latest 90 day outlook from Accuweather as always take all long range outlooks with a grain of salt.


Western Ohio Valley, Midwest, central/northern Plains – Some snow and colder air for the region. Temperatures start out the month well below normal in the central Plains and Midwest. Temperatures could rebound week two and back and forth later in the month. Still, temperatures can run several degrees warmer compared to 2018. Risk that we are not wet enough in northern areas and too wet in southern areas; use of winter products increase in this section, higher heating demand, especially early month (moderate confidence).


Western Ohio Valley, Midwest, central/northern Plains – Just like the Northeast, this will be a risky area from this far out, most modeling and analogs trend toward above-normal temperatures in December for northern Plains and parts of Midwest, but some analog years are still showing cold. We again are conservative from this far out, but temperatures and storm track can change drastically as we get closer, up or down on temperatures (low confidence).

January 2020

Western Ohio Valley, Midwest, central/northern Plains – There will be more extremes for this part of the nation. Arctic air may plunge at times in the northern/central Plains into the Midwest and Great Lakes, with blocking over northern Canada and Alaska. Couple of big snow events in the Midwest, especially Upper Midwest. Lake-effect snow is at a premium (moderate confidence).

One thing to keep in mind is all long range guesses are subject to change.

Nice compilation of stats Slim. Hope it didn’t take you hours and hours to look them all up!



Scattered thunderstorms are expected this afternoon. Severe weather
is not forecast, but cloud to ground lightning strikes and small
hail will be possible as the activity moves east through the area.

The heavier bursts of precipitation will contain both rain and snow
at times, along with the threat of lightning and small hail.

If outdoors this afternoon, be aware of the possibility of brief
heavy downpours, cloud to ground lightning and some small hail.


Temps in the low 40’s cold Thunderstorms ..Thanks MV…INDY

Thanks Slim – as you said, take the Accuweather forecast with a grain of salt….
