I use this all the time. Typically understates snow depth.

Called up the NOAA and they said this is accurate to a square mile updated several times an hour by satellite and then they fly instrumentation on commercial / military aircraft to get better data. Plus they deploy ground sensors.
Make sure the data is the latest by doing these minimal steps:
Pick a date in the future
SELECT PHYSICAL ELEMANT "SNOW DEPTH"
Select Overlays./ I like to have highways, rivers, lakes, stations, and for large areas a boundary.
THEN REDRAW MAP (make sure date is current)
