In like a , out like a

What is this?

This is a live-updating tally of the classic weather proverb, "If March comes in like a lion, it will go out like a lamb". It's based on real weather data, collected at my weather station in Queens, NY, and is updated once an hour thru the end of March.

Whenever March rolls around, I always end up ceaselessly tossing this proverb around in my head, trying to get a sense of how it "fits" to the actual weather. I like the idea that any given year could be Lamb/Lamb, Lion/Lamb, Lamb/Lion, or Lion/Lion. My lamb/lion factor is calculated by weighting a combination of: whether it's rained (any rain below 70 degrees = heavy lion), what the day's high was (medium lion < 50 degrees, heavy lion less than 45), and the wind (weak lion when it's greater than 7mph).

Please email me if you have questions/thoughts about how I've literalized this proverb, or check out the code I'm using to generate this. And here are the past years' lion/lamb results: 2024 2023 2022 2021 2020 2019 2018
