This displays the NWS Wind Chill and Heat Index Charts. Nothing special but thought I'd share if anyone is interested. Change the wxnwxcharts.php.txt to wxnwscharts.php and upload to server. Attached is the two charts. Upload to server and that is it. If you move images to a different folder make sure to change the path in wxnwscharts.php. Mine is below.
