Best Weather System?

[tdenmark]

What is your favorite weather system that isn't bogged down in detail, but provides quick reliable and interesting variety?

I kind of like the system in Chainmail

I enjoy using the Weather Hex Flower from Goblin's Henchman. It's PWYW, if you'd like to check it out: www.drivethrurpg.com/product/367072/Weather-Hex-Flower--Random-weather-generation--by-Goblins-Henchman

I like a one pager I believe came from the Harn world system.

I roll a d6 for precipitation and a d6 for "extreme."

No precipitation in the desert.
1:3 precipitation for wetlands.
1:6 precipitation everywhere else.

1:3 extreme weather in deserts and mountains.
1:6 everywhere else.

Extreme affects precipitation, if any. Otherwise it is some other affect related to the season. Cold snap. High winds. Scourching heat. Etc.

Each is a penalty to move rate. Both gives a double penalty.

This keeps things simple but works for me.
