No, it does not always snow after thunderstorms in winter

More often than not, thunderstorms in winter are not guaranteed to bring snowy weather.

CHARLOTTE, N.C. — Numerous thunderstorms this winter have renewed the questionable relationship between thunderstorms and snowy weather.

Numerous social media posts, and messages to Verify, inquired about an old wives' tale that promised snow ten days after thunderstorms in the winter months. 

While there are other variants of this myth that change the duration between the storms and winter weather, the idea is the same.

The Question

Students at the Goddard School of Matthews asked, "Is it going to snow ten days after thunder in winter?"

The Sources

The Answer

This is false.

No, thunderstorms in the winter do not always bring snow.

What We Found

"I remember my grandmother... when we'd have a thunderstorm in winter, she'd say, 'Oh, It's gonna snow within 10 days,'" Frank Strait, the severe weather liaison for the South Carolina Department of Natural Resources, recalled to Verify.

Weather records suggest no correlation between the two weather patterns.

For example, weather observations in Charlotte, North Carolina, which are recorded by National Weather Service equipment at Charlotte Douglas International Airport, showed that for 72 occurrences of thunder, snow fell within 10 days only 8 times, according to records since 2011. That equates to just 11% of the time.

"When you get a thunderstorm in the wintertime, it's usually because of a big change in the weather pattern," Strait said.

In a scenario where warm air gives way to cold air, a strong line of thunderstorms can ride that cold front, which acts as the transition point in the atmosphere. While the cold air can make temperatures favorable for winter weather in the days that follow, it does not guarantee snow or moisture of any kind in those days that follow.

With snow falling only 11% of the time after thunder in the winter, the suggestion that the two weather patterns are linked is untrue.
