What Happened to Our Cold Winters over the past 10 Winters?

This is an update to what I did yesterday but with a lot more detail. I have added CONUS scale winter temperature anomalies for each of the past 10 years so you can see for yourself, in your area how the cold winter frequency has changed (there is a summary CONUS scale summary table for this now too). I have added correlation slides from CPC and Physical Science Laboratories to show there really the correlation I am suggesting is true.

What Happened to Our Cold Winters of the Past?

At least over Southwest Michigan and likely most of the northern CONUS, we have lacked cold winter (relative to 1991-2020 normal) since the winter of 2014/2015, which was the last cold winter. I would suggest warming oceans are at least part of the story.

Storm Summary for the 27th into the 28th of February, 2024

Record high temperatures ( many cases all time record highs for February) were quickly brought to an end by a strong late February cold front. There were 21 reported tornadoes, mostly EF-0 and EF-1 but there was an EF-2 near Grand Blanc in Geneses County just ahead of the cold front. Temperatures fell around 50 degrees between Tuesday afternoon and Wednesday afternoon over Lower Michigan. There was 6 to 10 inches of snow in upper Michigan and locally 1 to 2 inches of rain in parts of southern Lower Michigan. Winds gusted to 69 mph over western Lake Erie.
