Since we get so little snow, I didn't even know there was way to enter a snow measurement until last week.
OTOH, I think the more important measurement is the moisture content, which is what you are seeing automatically (minus the amount that evaporates/sublimates). To me, the amount of snow is
mainly important to ski lodges and hydrologists plus a few specific others. Myself, I have never used the Snow Editor, we have local ordinances forbidding snow on the ground longer than 48 hours!
We do encourage rain except during the harvest season! I guess what I am saying is that I would not adjust my "rain" readings.
Of course, in areas where the snow only melts in the Spring, I would think a process of melting the snow would be appropriate to maintain a running figure for "moisture" accumulation (probably on a schedule?).
