The early run of Atmo's WRF-GFS model today has pushed the precipitation for southeastern Arizona a bit back in time, but the model forecasts a widespread weather event. First gusty winds, and then a Pacific frontal passage around sunrise on Saturday morning (above is forecast surface plot for Tucson area valid at 6 am MST on Saturday morning, April 14th). The greatest amounts of precipitation remain at higher elevations, but model still predicts a couple of 1/10s for the low elevation, metro area (below is total forecast precipitation through 11 pm Saturday night).
The model forecasts snow at higher elevations and keeps the snow level above about 6,000 ft MSL - below is forecast snowfall through 11 pm on Saturday night. The complete list of products available from the WRF forecasts at Atmo can be found at http://www.atmo.arizona.edu/?section=weather&id=wrf
There are nice color bar legends with these products, but I can't easily grab both the graphic and color bar with a screen snip.
