Weather is complex stuff, especially across the whole Omniverse, there are planets out there where it hails diamonds, or rains molten metal, and that's without crazy Fantasy stuff, we know these places exist within our own universe.
Weather is a complex, chaotic system, and it is almost impossible to calculate a true system that is completely predictive. So instead, we generally use random tables and cycles.

| 2 | Freezing / Solid (Snow / Ice) | High Cirrus: 1–10% Cover | Dry | Light Air: Smoke drifts and ripples appear on water, but you will probably not feel it. | Strange precipitation: Rains of blood, fish, frogs, jelly, petals and sand. |
| 3 | Cold / Solid (Frost / Snow / Ice Pellets / Hail) | Haze: 11-20% Cover | Dew / Frost | Gentle Breeze: You will feel the wind, leaves rustle. | Noctilucent Clouds / Aurora: Strange lights in the sky. |
| 4 | Cool / Liquid (Dew / Sleet / Hail) | Mists and Haze: 21–30% Cover | Heavy Dew / Hoar Frost | Fresh: You can fly a flag or a kite | Tornado, Whirlwind, Waterspout: A twister, a swirling vortex of wind, cloud, and dust or water. |
| 5 | Average / Liquid (Rain) | Fluffy clouds: 31-60% | Morning and Evening Mists | Breezy: Enough wind that you’d want a coat. | Heat Burst: Sudden rising of temperature after a storm. |
| 6 | Comfortable / Liquid (Rain) | Broken Clouds: – 61-80% | Spitting / Spotting (light drops of rain/ flakes of snow) | Windy: Strong steady wind that shakes large branches. | Heat Inversion: Hot air trapped over cold air. |
| 7 | Warm / Liquid (Rain) | Layered Clouds: 81-100% Cover High | Drizzle (falling mists of rain or snow crystals) | Gusting: Strong winds, whole trees shake, buffeting. | Firestorm: Often started by lightning. May include fire twisters. |
