I'm having this problem right now, trying to plan some nice long walks out of the city but it's been raining a lot lately. I'd love some kind of map of flooding/muddy conditions, but I don't think it would be feasible without a massive effort (as whether an area is prone to flooding or turning into a mudbath after rain depends on a lot of factors).

mentioned this elsewhere, but https://zoom.earth/ handles that ... (I've got nothing to do with them btw... I just think it's good)

Weather history sounds like a awesome feature. Sort of like a farmers almanac built into a modern weather app?

CARROT has this and it’s amazing! You can “time travel” back as far as you want. Absurdly far, even. I can tell you that it was 20 degrees in my town on Jan 1st, 1940.

Carrot Weather’s most expensive subscriptions include 30-day history.

In the app, you can swipe backwards in time and see the reports and data for yesterday.

One of the main features of my weather app is yesterday's weather: https://weather-sense.leftium.com

This is exactly what Precip does. Other apps just show the past forecast which can often be wrong. The Precip app uses radar to measure what actually happened so you'll know if that trail is muddy or not. https://precip.ai
