SNOW SQUALLS: Dangerous winter driving conditions

Published: Friday, December 09, 2016 @ 4:29 PM

Snow in Liberty Township

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.
