CHICAGO (WLS) -- A fast-moving system brought a burst of heavy snow to the Chicago area Friday evening, prompting snow squall warnings from the National Weather Service.

A snow squall is defined as a short but intense burst of snow accompanied by strong winds that can produce whiteout or near whiteout conditions, ABC7 meteorologist Cheryl Scott said.

Snow squall warnings were issued as a fast-moving system brought a burst of heavy snow to the Chicago area Friday evening.

The snow squall line was brief but intense as it blasted its way through the Chicago area around 10:30 p.m. The system was so unstable, Doppler 7 MAX Radar even picked up some lightning strikes in southeast Wisconsin.

Drivers were warned to avoid travel until the snow squalls passed. So far, no crashes related to the squalls have been reported.
