From the developer:
WC Temperature Rising is a script that allows you to create Growl notifications from WeatherCat temperature alerts. The script makes a guess of what the threshold was set to by rounding the actual temperature to an integer. Therefore it can only be used to create a Growl alert for temperatures that are integers (no decimal fraction).
