All weird weather is preceded by something indicative.  Strange looking clouds, “squirming” in the sky (or behind it), chaotic droning from the sky, etc.  Weird weather doesn’t come as a surprise, and you usually get 1d4 hours warning.  It lasts for 1d6 hours, unless indicated otherwise.

Acid Rain corrodes metal, wears down stone, ruins cloth, kills fish, and does 1d6 damage per minute if you are caught in it.  More damage afterwards, too, if you don’t get that stuff off your clothing and skin. 

Antigravity pillars roam over the land like searchlights from mars (which they might be).  Things caught in the beams fall upwards for 3d20 seconds before falling back down.  Cars are dropped on buildings.  Schoolchildren pepper their playground like a dozen dropped eggs.  Smart folks hang out in their basement and tie themselves to the floor.

Blackness.  No sun.  No moon.  No stars.  It’s as dark as being in a cave.  Up above, you can hear slow sliding noises, like someone is sandpapering a square mile of elephant skin.  And there are things reaching down, extinguishing the bonfires and the lights, clustered so tightly in the sky that no light gets through.

Blasphemous Clouds!  Deformed, inhuman faces appear in the clouds and rain down booming indictments, blasphemies, and profanities.  20% chance they tell embarassing/horrific secrets from one of the PCs past.  20% chance they tell horrible lies about one of the PCs.  Wasps fly down and sting people who talk back to the clouds.  The clouds say whatever will disturb people the most: dead baby jokes, mockeries of god, homoerotic poetry. . . whatever will make the most children cry.

Burning Clouds!  The clouds turn red, roiling masses of angry cinders.  20% chance it rains fire.  20% chance it rolls along the ground like asshole fog.

Distant Space.  Oh wow.  For 1d6 hours, it looks like the Earth has been teleported to some distant part of the universe.  5% chance bathed in the warmth of another sun, 95% chance the temperature drops 10 degrees F per hour.  Independent 10% chance of deadly meteor shower.

Drunken Fog!  This fog is way more fun than the hungry fog!  Everyone it touches gets wicked drunk!  Chance for alcohol poisoning is low, but don’t drive a car.  The police try to pull people over but they drive into ditches.  Sometimes bad stuff attacks, ‘cuz it knows that everyone sucks at fighting back.

Empty Wind!  If this wind blows on a living creature, it will be transported into the future!  D6: 1-2 is 1d6 rounds / 3-4 is 1d6 hours / 5 is 1d20 days / 6 is 1d6 months.  There is a 10% chance that this wind will be ethereal, and will blow through walls, affecting everyone.  Transported creatures arrive naked, covered in sunburns, and smelling like campfire.

Hallucinatory Skies are completely harmless, but they are freaky.  D6: 1 - fleshy eyes and faces peering down / 2 – warped vision so that you can see over the horizon and appear to be in the bottom of a bowl / 3 – planet appears to be spinning at 1000x the normal rate (nauseating if you watch it) / 4 – flickering sheets like grey membranes shot through with pulsing yellow veins / 5 – bright light and an orchestral roar, temperature raises 10 degrees F / 6 – clouds appears to be animals fighting/fucking/running, etc.

Hungry Fog!  The fog comes in on little cat feet, a hungry stomach, and sucking tendrils like giant hungry elephant trunks.  Hide and seek as the fog breaks down doors and windows, trying to suck you into its central stomach, where you will be held above the ground, paralyzed, slowly whirled around, and digested in layers.  Lasts 1d6 hours, and usually leaves piles of bones, shoeleather, and keychains in the town square.

Insanity Sun.  The sun shrinks down into a tiny pinpoint of bluish-white light, although its still brighter than a full moon.  Everyone who looks at anything illuminated by this watery light, even for a second, goes stark, staring mad and will mumble about “the people behind the sun”.  Unless they make their save.  Town is full of people with blindfolds on, and other people trying to rob them.

Low Gravity!  Like, 1/10 of normal!  It’s like being on the moon!  You can jump really far!  Waves look really cool!  You suck at throwing things because they don’t arc the way they should!  Running is difficult without traction!  Lasts for 1d20 * 10 minutes, and then whops back to normal.

Noxious Rain causes vomiting and mutation if you get more than a few drops on you.  Save negates.  It looks like thin, golden brown fluid that smells like a pile of goats that died of dysentery last week.  Use your favorite mutation table.  Afterwards, brown mushrooms grow out of everything that isn't metal.

Painted Rain comes down in different colors.  D6: red / orange / yellow / green / blue / purple.  Mostly harmless, but the green one causes mercury poisoning and the blue one causes hallucinations.  Surfaces (and people) will stain that color until it is washed off.

Rain of Gasoline! A very bad time to have a cigarette craving.  This is why we don’t have wooden buildings anymore.  Inevitably, a fire starts by the end of it.  Air quality = shit.  Sewers, waterways, rivers, lakes, ocean runoffs will all become infernos.  Afterwards, oil stains and ashy smudges.

Rain of Horror! Roll a d6: skulls / skeletons / heads / headless corpses / garbage / ectoplasmic ghost guys that crawl around moaning piteously before dying.  20% chance that this stuff comes to life and attacks everyone.

Rain of Knives! Actually just pieces of really sharp ice.  D4: 1 – icicles / 2 – ninja star snowflakes / 3 – no physical knives but things just start getting cut / 4 – totally metal knives, I lied about the ice.

Rain of Meat!  Most of these are bitesize, but roll d20 * 100 to see how heavy the biggest chunk of meat is (in pounds).  20% of the meat is recognizable, 20% of the meat is poisonous, 20% of the meat looks pre-chewed.  A lot of carnivores slouch in from the hills.  Slorgs go into gluttony mode.  Afterwards, everyone makes bonfires.  Alternatively, fly swarms next week like Moses hates you.

Rain of Noise! Metal rods fall from the sky and vanish upon hitting the ground.  Each one sounds like a gong, or an off-balance washing machine, or a destruction derby, or a rhino in a china shop, or two skeletons fucking on a tin roof.  Conversation is impossible.  Cover your ears or save vs deafness.

Rain of Rage!  Blood rains from the sky!  Anyone who gets it in their eyes or mouth flips out in a murderous rage!  They kill their loved ones first!  All recorded music is temporarily replaced with Cannibal Corpse!  Even U2!  After the rain stops, affected people make a save to avoid being rageful forever!

Rain of Slime! Globs of carnivorous slime.  Tough to kill, but sunlight, fire, cold, and salt destroy it.  Normally immobile, but if it eats enough (falls on an unlucky herd of cattle), then giant blobs rampage through town eating people.

Rain of Soot!  Hot ashes and soot rain from the sky!  1d6 feet of it!  1 damage per round if you are caught out there.  Afterwards, snowplows and choking hazards.

Rain of Vermin! D6 frogs / locusts / lice / snakes / minnows / rats.  50% chance that the vermin are a new species.  50% chance that they all share a specific deformity (no eyes, no mouth, no head, two heads, no limbs, spider limbs, etc).

Rain of Worms! Most of these are just 3” long carnivorous worms, but roll a d4 * d4 to see how big the largest ones are (in feet).  These are stormworms, with mouths like rotary electric razors and skin in big leathery flaps.  They take minimal damage from falling.  They mostly devote their energy to eating each other, and afterwards people make hunting parties.  Like a lot of these weird weather effects, looting and burglary are rampant.

Reverse Rain pulls water from the surface up into the clouds.  If a creature isn’t indoors or underwater or something, they take 1 damage per minute as they desiccate painfully.  Pink clouds form over crowds of people who are losing a lot of blood.  Green clouds form over forests.  Most clouds formed this way are yellowish brown.

Reverse Stone Rain!  Pieces of rock break off of everything and fly into space.  Buildings look like bites are being taken out of them by invisible rats.  Your exposed skin with also break off in fingernail-sized servings and fly away.  1d6 damage per round after your clothing is gone (shouldn't take more than a couple of rounds).

Stone Rain!  Stay indoors.  Mostly pebbles, but sometimes fist-sized stones and 1d4 boulders!

Sun Invasion.  There isn’t just one sun.  There are hundreds.  Of all colors and sizes.  Swelling, swarming, and eating each other.  Sometimes things outside spontaneously combust for no reason.  Temperature raises 20 degrees F.

Thick Air.  The air has the consistency of water.  Breathing is exhausting.  Old people die.  Guns and engines don't work.  Fish swim out of the ocean and through the air.  When the weather ends, all the fish swimming over dry land drop and die, gasping faces mouthing the word “Why??????”.  The fish all die looking betrayed.
