Look for the dark 540 line.
If this line (or any line less than 540) is over us then it means the
air is cold enough to snow down to 1400m or so.
If 522 is over us then it should snow to sea level!
You can also look to see if precipitation is likely, and see predictions for a range of other things that are presumably useful to someone.
