The noaa image is in WGS84 coordinate system, by nature, it can not be overlay on top of Google base map accurately without a re-projection of the image itself.
If re-projecting the image is not an option, you need to approximate the overlay with a technique that used for image sprites, which is what groundoverlay does. You break up the image vertically into small pieces, and apply projection to those individual slices as the background of a div, not a img element. if you want use groundoverlay, you can set the style of the "pane.overlayLayer" with some sort of transparent, use a fake overlay to get access to it. Downside is that all overlays will have same opacity. or you can fire an enhancement request via issue tracker and see what happens.
