Where Does This Winter Cold/Snow Rank All-time in Cleveland?

Frozen Tundra covering Lake Erie

The meteorological months of winter are December, January and February. The snow cover across northern Ohio is very deep after the recent snowfall. This endless blanket of the white stuff makes this definition seem, at the very least, misleading and pretty pointless to many of us who still have snow piled up high. When we do meteorological comparisons to past seasons, the three month periods nearest to the season in question is used by climatologists. For example, December through February are the winter months. March through May are spring months and so on.


So how does this winter compare to last winter (colder than average), two winters ago (milder than average) and the coldest winter ever (1976-77) in northern Ohio?  I'll use the same metrics for comparison I've used in the past:   

Average 3 month temperature rank all-time (December through February) since 1871
Seasonal Snowfall
Below zero nights
Days at or above 40
Days at or below 32
Consecutive days with at least one inch of snow cover
Total days with snow cover of at least one inch
Total days with snow cover of at least six inches

Monthly temperature ranks

Coldest Morning Since 1994!


It took a while to clear the skies out Friday morning. But once the clouds dissipated and the winds died down, the temperatures dropped. -4 at Hopkins at midnight. By 5:45am, the temperature dropped to -17, the coldest reading since January 19, 1994, the 4th coldest EVER in Cleveland. It is also the COLDEST February temperature breaking the record of -16 set on February 10, 1899!

Coldest region is in rural Geauga, Ashtabula and northern Trumbull counties.  Weatherspy temperatures on the WEATHERSPY BLOG

-39 at 7:37am in Rome, Ohio!

Look at what happened to the temperature in Rome, Ohio once the winds died down. The temperature dramatically dropped during the evening and especially since midnight.


Issues developed around 6am on the roads around the area. When the skies cleared out with calm winds, frost formed on the dry pavement. The fresh glaze on the road surface with temperatures between -15 and -20 caused multiple accidents on the major interstates around Cleveland.




14% of the US is below zero this morning.

 Much of deep south was below freezing.


Florida is in the 20s north of Orlando.



Here are some photos of backyard thermometers from across northern Ohio.

How Much Do Temperatures Climb After A Below Zero Morning?



Since the snowfall Sunday, temperatures have been in the deep freeze across northern Ohio and surrounding states.  All locations dropped below zero Monday morning and again Tuesday morning. So how much have temperatures rebounded after these -10s and -20s?  Here are the temperature recording graphed out for 15 locations around Ohio since late Sunday. I labeled the coldest readings for the last 2 mornings.

Notice how the temperatures vary from place to place depending on the snow cover, proximity to the lake, sky condition and wind speeds.

How cold has it been in your backyard?
