Another November day with sunshine and mild temperatures. Our high today was 53 degrees. Today’s average high is 46 degrees. Ten of fifteen days this month has had highs above average. The nicest part of this November is the unusual amount of sunshine. November is tied with December as the cloudiest month on average. Our temperatures will continue to be above average every day this week except for Thursday.
Last weekend’s big snowstorm that missed us to the west was the first snowstorm of the season in Wisconsin. It may seem early for a storm of this magnitude, but it actually is pretty average for timing in Wisconsin. Take a look at the last 30 years in Wisconsin.
Last year, Wisconsin did not have a major winter storm until December 13, and 14th , however you can see some years had storms as early as the first week of October. SE Wisconsin does not usually get big snowstorms in November, but that changes as we get into December. I want to thank the National Weather Service in Sullivan for the graphic.
The above graphic is very interesting to me. It goes back to the mid 1970s counting the number of major winter storms that hit Wisconsin. I found it pretty surprising to see more major winter storms in the 1990s and 2000s than in the 1970s and 1980s. A winter storm is defined by the following:
1. Snow accumulations of 6 inches or more,
2. Blizzard conditions for 3 hours or more – visibility below 1/4 mile due to falling and/or blowing snow with frequent wind gusts 35 mph or higher,
3. Ice accumulations of 1/4 inch or more in 12 hours or less due to freezing rain
4. Sleet accumulations of 2 inches or more in 12 hours or less,
5. Snow accumulations of 3 to 6 inches with sustained winds or frequent gusts of 25-34 mph and intermittent reductions in visibility to less than 1/2 mile resulting in closed roads, etc.
I was surprised that the 1970s had fewer storms. As a kid, I always thought the 1970s were much snowier than the last 20 years. If you have any theories of why, let me know in the comments section.
Finally, I wanted to share the visible satellite image from today.
The areas with snow cover had highs in the 30s today. The surrounding areas had highs around 50. The snow will quickly melt as the week goes on. Thanks for reading.
