Currently mine is showing snow covered background scene (even though we don’t have any). As you flip thru the days ahead, it keeps flipping back and forth between snow covered and not even though we have no measurable snow predicted except maybe 1/2" Monday night.
What data sets this scenario? It may need a look at because it is inaccurate.
In the winter season the temperature has to be more that +5 C winter for the landscape to be substituted with the naked one.
Don’t believe that to be the case.
Today 54F = snow covered landscape.
Tomorrow 42F = bare landscape

I admit your location doesn’t seem to follow the rules.
