Why Storms Sometimes Paint the Sky Green

The greenish tint that occasionally colors the sky before a storm isn’t just a quirky weather trick—it’s a clue about what’s happening inside the clouds. When sunlight cuts through a storm, the way it bounces off hail and raindrops can shift the colors we see. If the storm is close to sunset, the light gets filtered in a way that lets cooler tones like green and blue slip through, while warmer reds and oranges stay higher up. This is why some people call it "tornado weather, " though the real cause is more about ice than wind. Not all storms turn green the same way. Big hailstones tend to cast a yellowish-green glow, while smaller ones with heavy rain create a bluer shade. The bigger the hail, the more dramatic the color shift. That said, green skies don’t always mean danger, but they do signal that the storm is packing serious power. Hail this size usually means the storm has strong updrafts, which can also spin up tornadoes. So while the sky’s color is interesting, it’s just one piece of the puzzle.Missouri’s March weather is famously unpredictable. One year, spring arrives early with shirtsleeve temperatures. The next, a surprise snowfall buries the ground. This year, no green skies or storms are expected, but the state’s usual weather roulette means you can never be too sure. A shift in the weather pattern is on the way, though. A strong high-pressure zone is moving in, promising clearer skies and warmer air. By midweek, temperatures could climb into the 60s and 70s. If the trend holds, the month might end with near-record warmth. Just another reminder that spring in the Midwest is full of surprises.
