Jeff,
Thanks for sending the image. I tried something very similar using the same
colors, but only with precip. Resulting image attached, along with the
short script to produce it. I also attached the "USNE.png" background map
used.
One of the differences I see between your and my image is that your
displayed (foreground) image borders appear to be transparent while the
plotted white is not. My image sample appears to be true in reverse, but I
don't know why. Perhaps my sample script will give you a clue.
