Dave, Others and you too Ned,

A snow sensor is only good for the immediate area of the sensor.  Think in 
terms of feet.  As an example, on 30 June 2010 the SNOTEL sensor at Harts 
Pass registered zero (0") of snow yet 100 feet away on the trail we walked 
through 2 feet of consolidated snow.  I believe this problem exists with 
most if not all traditional sensors.

Since then postholer.com has added some pretty neat features for his Google 
Maps implementation.  Specifically, at http://postholer.com/gmap/ on the 
right is a drop down titled Map Skins with a whole series of selections 
under the heading Todays Snow Analysis.  I've discussed this toll with 
Postholer and he gets a daily web services update from a NOAA satellite 
resource.  This past year when hiking in the same area I was able to compare 
those maps with what we actually saw on the ground and found the information 
both useful and accurate.

This is my go to resource for snow planning.  Take a look today and there is 
snow where you would expect it...  Hope this is helpful,
