My region saw heavy thunderstorms and flooding today. Roads became impassible in minutes, and two people were struck by lightning. Of course, this extreme weather got me thinking about weather and Filos. Do you record the weather in your Filo? Do you find it helps you remember a certain day?
I usually only write down when it snows, especially when it's a significant number of inches. I also note any astronomical phenomena to look out for, like a meteor shower or comet. (Unfortunately, I'm a little too far south for the current aurora borealis.)
