I must have an old settings.php file, it didn't have the snow setting. I added it and all is well. Fixed the barometric link too. All my barometer readings are showing up in red, so I must have a setting problem with it too.
Much appreciated.
Each of the scripts have settings that you can customize to your climate. The default non-metric settings are what works for me.
The default metric settings were just a WAG by me. So those of the metric persuasion will most likely need to change the defaults.
It looks like you could change the range start from 900 to 980 and change the increment size from 10 to 5.
$barorange_start = array(29.75, 900);
$baro_increment = array(.05, 10);
