ty for posting this I often looked for accuracy on th emodels and didnt really ever find anything like this
 

There isn't any really. I'm using a super raw method to do it by getting nohcos 24hr snowfall map based on some observations then estimated. Then getting images from models for same period. Using python to try to make sure maps are for same area because I have it map each pixel location, and RGB value and assign snow based on legend RGB value. Uploaded it all to gemeni pro and have it run that statistical analysis, pull into my notebooklm of meteorology books, papers, to help interpret, then produce nice infograph for it all. Haha, honestly it's a pain and wish I could automate it more. But worth it for first big storm to explore the concept. Take into account there are a myriad of ways to arrive at right snowfall for wrong reasons. I'm hoping it harder to arrive at large area of right snowfall for wrong reasons.

its still something to look at and gives a bit of info honestly we should have a way to do accuracy with model. we all know models swing and miss and sometimes they get it right. but having a accuracy model for them would be awesome. cause in a given year it feels like some of the models are in the teens for accuracy

Latest HRRR still looks great
