Rare Thundersleet Strikes Texas During Winter Storm
A winter storm swept through Texas over the weekend, bringing icy roads and sleet. But in some areas, the storm also produced a rare weather event: thundersleet — lightning and thunder mixed with sleet.
What Is Thundersleet?
Thundersleet occurs when conditions are strong enough for thunderstorms, but ground temperatures remain below freezing. In these cases, ice particles in clouds melt into rain in a warm layer, then refreeze as they fall through cold air near the surface, turning into sleet. The storm’s energy creates thunder and lightning during this process.
Why Is It Uncommon?
This phenomenon is rare because it requires a specific combination: thunderstorm instability + sub-freezing surface temperatures. Those conditions don’t often happen at the same time.
Sleet vs. Snow
Many people saw a white coating on the ground and assumed it was snow. But the storm actually produced ice and sleet, not snow.
•Sleet forms when snow partially melts in a warm layer, then refreezes before hitting the ground.
•Snow forms when temperatures stay below freezing from cloud to ground, allowing snowflakes to reach the surface without melting.
Thundersleet is a rare reminder that winter storms can still surprise Texas. Even when it looks like a typical snow event, the weather can behave differently, and dangerously, with ice and sleet.
