Alex from our time working together, while he was in nursing school. Later, he moved to ICU, working as a nurse to support critically ill Veterans. He had such a great attitude. We’d chat between patients about trying to get in a mountain bike ride together. Will never happen now

I have that checked out from the library. I should read it!

While we’re being bombarded with weather maps, I thought I’d revisit one of my favorite color palette tricks. Sometimes it’s important to emphasize a boundary, perhaps between moderate (< 6") and severe (>8") snowfall. You could reset the palette, like the NYT, but there’s a better way.

I don’t think so, since they did total accumulation and you had to sum 72 hours worth of individual forecasts to get that.

I think the way they’re blending in the shaded relief makes everything darker.

If you’re picking colors with a tool that has precise control over hue, chroma, and lightness it’s possible to abruptly shift hue while maintaining even steps in lightness. This creates an unmistakeable transition that’s still monotonic!

If you want to try this at home @obumbratta.com built the palette generator I used here. It’s got an elegant interface, and takes advantage of OKLCH, a state of the art color space that addresses some anomalies in CIE L*C*h Color Space.
