Every morning as I reach work, I peek into the eight-inch canister behind the visitor center. If any precipitation has fallen in the preceding 24 hours, it is measured exactly. Multiple measurements are taken in winter: new snow depth (measured on a white board swept clean daily), standing depth (measured on a stick secured in the ground), and new snow in the canister melted and measured to the nearest hundredth of an inch. Our digital temperature recording device marks highs and lows of the previous day. We note the hours during which weather events happened, any related observations (e.g., “snow squall with thunder clap,” or “wind blew tents down”), and oddities like hail or fog. Part of our morning procedures includes logging on to the National Weather Service data collection site and putting all our numbers safely into their system. I hope that gives meteorologists something interesting to study when storms are utterly absent.
I must say that my favorite hand-written observation in the weather book last year was on October 25: “screaming double rainbow 4:37 pm.” Take that, National Weather Service!
