We see snow squalls in the Miami Valley nearly every winter season, even though they are most common in lake effect snow areas.
WHAT IS A SNOW SQUALL?
StormCenter7 Meteorologist Kirstie Zontini describes a snow squall as a burst of snow that quickly drops visibility levels to zero. They are usually accompanied by gusty winds which only make visibility worse as snow blows and falls simultaneously.
WHY ARE SNOW SQUALLS DANGEROUS?
Snow squalls are very localized. Driving conditions and roadways can look clear and safe one minute, and a minute later, you can't see. Drivers are caught in the whiteout as they are traveling at fair weather speeds which can result in chain reaction rear-end crashes like the incidents below.
Heavy snow squalls and icy conditions led to a 75 car pile up on I-90 in Ashtabula County, Ohio.
More than 20 cars collided during a snow squall in Shelby County on I-75 between SR 274 and 119.
More than 50 cars were involved in a pile up on I-75 between Middletown and Monroe on January 21, 2013.
No one was killed but the highway was shutdown for hours as emergency crews rescued drivers trapped in their cars and cleared the highway of debris.
Stay weather aware this winter no matter where you are.
