I've been having instances lately when there is a light rain for no rain rate to show up, but the rain total will increase. This has been happening when only seeing the minimal .04" of rain. When it rains any heavier, the rain rate shows up. Previously any time there was rain recorded the rain rate would appear. Is this a symptom of the hardware going bad?
I first noticed this on the wunderground data for my station. I thought it may be a transmission error so I added a rain rate graph to VWS and saw the same thing. Today I confirmed it not happening on the weater station display when I saw the daily rainfall increase by .04" and the display continue showing a 0.00" rain rate.
I'm planning on doing the mod to my rain gauge at year end to increase the resolution. Wondering if there is something else I may need to do to fix this.
