Hello Brian. This shouldnt be to hard of an idea to add if you can add an alarm for the wetbulb temperature since I use it every day during the winter months especially when the wetbulb temperatures get from 28.0F and below. Like to have this alarm so I know when to start snowmaking :!: SNowmakings suitable for temperatures below 28.0 wetbulb.
