For those of you who are using my
wxgr3hanis-dbZ script to display your local radar images, sometime sooner or later you will need to switch over to the winter scale and push the 'T' button on your GRLevel3 program in order to better display the local radar conditions.
T-Button:

There's a switch, 'winter = false', that should be set to 'winter = true' in 'wxgr3hanis-dbZ.php' and 'wxgr3hanis-dbZ-SA.php' so that the appropriate scale is displayed to the left of your radar images.
Of course this procedure should be reversed come Spring in your area.
The script is available on
my scripts page.
