There are some remote weather stations across the state.
Find them all here: http://mesowest.utah.edu/cgi-bin/droman/mesomap.cgi
None in southern Arizona have snow-depth readings.
But many DO have precipitation gauges... so based on the elevation of the station and the amount of precipitation it has received, combined with recent temperature readings, you can do some guesstimation.
You'll want to change the region to ARIZONA and change the network to All.
When you select a station from the map there are options to view/download data from that station for different periods of time.
As you get closer to your hike time, I recommend calling the rangers office for Sierra Vista and Catalina districts. They would have the best information on current conditions in the forest.
Research is fun!
