If you're using the Saratoga template USA version you can get local graphical forecasts using
this script. Precipitation amounts appear when they are forecast. Be aware that it's utterly dependent upon appropriately set values in your Settings.php, and there are some instructions/caveats included in the main script.
I just updated an outdated link for the local WFO, so it should be good to go.
As usual you can get the script
here.
Update 9 am CST: an eagle-eyed user noticed a small discrepancy in his results vs. mine. A new variable for your time zone has been added to the latest script iteration, and it should be set to your time zone in order to get the best results.
