Greg,
If I'm understanding your question correctly, here's how you would
reorder your array (I'm assuming your array is 2D in this case):
snow = file1->SNO_D_GDS5_SFC
snow!0 = "x"
snow!1 = "y"
snow_reorder = snow(y|:,x|:)
For more info, see:

Of course, if the dimensions are already named, then you can skip the
naming of the dimensions, and just use the dimension names that
already exist.
