Across the entire U.S. if all snow since October 1, 2018 fell uniformly, then 39.6" would cover the Lower 48.

Most snow on average per state:
Maine: 110.4"
Vermont: 109.9"
Idaho: 100.9"
New Hampshire: 90.9"
New York: 88.4"
Michigan: 84.5"
Montana: 82.3"

So much snow in the Northern Winter ski resorts staying open ’til summer

March 21, 2019

Excerpt:

Remember when Dr David Viner famously said “Children wont know what snow is?”

To paraphrase Tony Heller: “Soon Children Wont Know What Science Is”.

Two weeks ago snow mass in the Northern Hemisphere hit “exceptional”. This graph below is from the Finnish Meteorological Institute and unlike other datasets includes both snow and ice. They don’t say if this is an all-time record (since 1982).

Look at that chart: Total Snow Mass for the Northern Hemisphere (excluding mountains)

Now watch the tortured explanations on why exceptional Cold and Snow events doesn't matter.
 
You put up a graphic showing a snapshot of a portion of one winter's total snowfall. No history. No comparison.

I put up a graphic that shows the CHANGE in snowfall totals over the course of 67 years.

Our audience can judge which actually provides data concerning the trend of snowfall in the contiguous United States.

I’m sure this is bad for Polar Bears somehow.
 
Your second graphic covers less than half the period my graphic displays.
 
No time soon, but it is shrinking. But you didn't need anyone to tell you that.
 
You should perhaps check out the final report of the Finnish GlobSnow project (which stopped collecting data in 2012) whose data you were displaying. Here from the abstract:

This report presents an overview on the main activities and a synthesis of key results of the ESA DUE GlobSnow-2 project. The key objective of the project was the further development of methodologies for producing long-term records of snow cover information at the global scale intended for climate research purposes. The efforts were focused on developing methodologies for the retrieval of snow extent (SE) and snow water equivalent (SWE) information based on satellite data.

So this was not a data collection project. It was a project to develop methods to collect data. For instance, trying to figure out how to accurately measure snow cover on different types of terrain and plant cover. Have a look through the report and you will see what I mean. What you will NOT find is data such as that you posted. A hint at that absence might be this paragraph from their Conclusion:

It is necessary to evaluate the agreement of the GlobSnow SE and SWE snow extent estimates, and develop methodologies for merging of SWE and SE products on a coarse spatial scale (25km EASE-Grid). Dry snow detection and snow extent mapping could be improved through the use of time series of radiometer data, the opticallyderived GlobSnow SE products, and/or a fused SWE/SE dataset. Existing hemispheric snow extent datasets (i.e. the NOAA IMS snow charts or AVHRR-based datasets) could be used for validation, or as a source of snow mask information.

And here, for your edification, are two NOAA IMS snow charts:

The left hand chart is snow cover extent (SCE) from 1980 to 2015. The right hand chart is percent change per decade from 1998 to 2016. Note that all data here are below zero - ie, all values are declining.
