A snow squall warning has been issued by the National Weather Service and continues into Wednesday night, affecting highways in parts of Cook County, Illinois, and Lake County in northwest Indiana. The current warning extends until 11:15 p.m. and is mainly affecting areas in southern Cook County and northern Lake County. Reports indicate wind gusts could reach up to 50 miles per hour, with visibility significantly impaired due to the blowing snow.
Officials from the NWS are urging the public to be cautious, highlighting the potential for “dangerous, life-threatening travel” in these regions.
So, what exactly is a snow squall? The NWS describes it as a brief, intense burst of snow accompanied by strong winds, which can create whiteout or near whiteout conditions, making it a serious wintertime weather hazard. Forecasters have issued a warning, noting that both severe injuries and fatalities can occur if individuals leave their vehicles during a snow squall, as low visibility makes it difficult for drivers to detect others or safely stop.
Tragically, there is a documented history of serious traffic accidents linked to snow squalls. While snow accumulation during these events is often minimal—typically an inch or less—the combination of strong winds, dropping temperatures, and abrupt visibility reductions can create perilous conditions for motorists.
Interestingly, snow squall warnings are usually brief and target specific areas, remaining in effect for approximately 30 to 60 minutes, much like tornado or severe thunderstorm alerts.
In the face of hazardous weather, it’s important for drivers to remain vigilant and take precautions. Staying informed and avoiding unnecessary travel during these intense weather conditions can help ensure safety for all.
This warning serves as a reminder that while winter can present challenges, awareness and preparedness can significantly mitigate risks.
