I try and be consistent and somewhat logical in my thought process - I had a T of snow in May 2020. In my mind, I had snow in May. Same thing applies to today with rainfall; HOWEVER,
Say it rains from 1:35am to 2:15am, doesn't reach measurable status in my gauge, and the ground is 100% dry by morning...what I don't see affects my perception. In that case, the streak would live on.
I really don't know. I guess I could argue both sides.
