Recent Seasonal Snowfall Totals - Northern Ohio/Midwest/US - Part II

We start the snowfall retrospective with last winter's (2019-2020) snow totals in northern Ohio.

Last year was the 5th straight year with below normal snowfall. The longest stretch of below normal seasonal snowfall was 9 winters between 1963 to 1972. 

Here are the average snowfall totals for northern Ohio. (Color contours are different than the image above)

How about the last 10 winters?  Here are the local snowfall amounts. Colors might be different year to year.

Last year's running snowfall accumulations really tell the story when compared to other years.  (Hat tip to Jared Rennie for supplying these snowfall graphics below)

Ohio, Indiana and portions of Michigan saw below normal snowfall last winter. Yet snow was above normal snowfall across Illinois and the upper midwest.

Notice the high snow numbers across the Upper Peninsula of Michigan.

Overall snowfall departures last winter across midwest/Great Lakes. 

The last 5 winters (2014-15 to 2018-19) snowfall vs normal below. Last time Ohio had above normal snowfall was 2014-15.

How about the rest of the country? US snowfall vs normal over the last 6 winters. Purple is above normal snowfall. Tan/brown colors are below normal. (Thanks goes out to Jared Rennie for the images)  Last image is the winter of 2014-15.

Recent Winter Temperatures - Northern Ohio/Midwest/US (Part I)

We start off with last winter's temperatures vs normal across North America. Little sign of any cold although early February showed some signs in the central US.

US temperature anomalies (standarized) show a similar story month to month

Here are the previous 5 winters (Dec-Jan-Feb) for comparison.

WINTER 2017-18

WINTER 2016-17

WINTER 2015-16

WINTER 2014-15

As for the midwest and Ohio Valley, last winter's temperatures ranked in the top 15 warmest ever across Ohio, West Virginia, Kentucky and Pennsylvania with top 20-30 warmest further west.

Here are the previous 5 winters (Dec-Jan-Feb) for comparison. Numbers indicate local climate division rank (1 is warmest. 128 is coldest)

Looking across Ohio, the overall temperatures are similar. There are 10 climate divisions across the state. Divisions 2,3,6 and 7 cover northern Ohio.

Division 2,3,6 and 7 make up northern Ohio.  All four divisions last winter ranked top 10 warmest. Each division is below. I also included overall Ohio winter temperatures vs normal.

Winter Temperatures vs Normal - Ohio Division 2

Winter Temperatures vs Normal - Ohio Division 3

Winter Temperatures vs Normal - Ohio Division 6

Winter Temperatures vs Normal - Division 7

Winter Temperatures vs normal - All Ohio Divisions

Here are the top 20 warmest and coldest winters in northern Ohio (Hopkins Airport 1938 to Present/Downtown Cleveland 1871 to 1938)

As for northern Ohio specifically, last winter was very similar to the winter of 2016-17, 2011-12 and 2001-02. 

Here are the winter temperatures vs normal (using moving 10 year averages) since 1960

As I have written many times, most of us don't remember the average of the days we typically remember the extremes.  Here are the number of days each winter we reached a certain temperature threshold since 2000.

Number of Days Above 40 Degrees (Dec-Jan-Feb) out of 90 days

Number of Days Above 32 Degrees (Dec-Jan-Feb) out of 90 days

Number of Days With High Temperatures BELOW 20 Degrees (Dec-Jan-Feb) out of 90 days

Number of Nights BELOW ZERO (Dec-Jan-Feb) out of 90 days

Expanding out the winter list further in time, here are the number of days above 40 degrees since 1940

...Number of night below zero since 1940

Here is a graph highlighting the hours the WIND CHILL dropped below a specific threshold over the last 15 winters. I added a few other notable winter of the past for comparison. Last winter is on the left side of the image below.
