@sturdley, I have just started to log Cupertino data. One initial question, can you confirm whether there was heavy rainfall overnight in Cupertino?
OWM was reporting 40mm/hour of rain around 1-3AM on the 8th June. I didnt see any reported rainfall on any of the major weather sites and neither DarkSky nor WU reported rainfall. I have included a screen capture of their report at 09:30 BST today. The fact that the same image shows humidity at just 35% suggests something wrong in the back-office. I have submitted a ticket and curious if they will respond and what they say.
