In WeatherCat 2 we can have up to three variables involved in calculating a weather condition. At the top of my list, I added a rule that says:
If Ext Temperature is less than or equal to 33.0˚ F AND if Precipitation Per Hour is greater than 0.0 inches/ hour THEN Current Condition is Snow.
This rule did not trigger Snow all day, even though the temperature never exceeded 33˚ F and the ISS recorded .09 inch of melted snow in the rain cup.
Why didn't the condition ever display Snow?
Thanks.
