A winter weather system is set to impact the Chicago area, potentially bringing “snow squalls,” which can pose serious risks to drivers. The National Weather Service (NWS) describes snow squalls as brief but intense bursts of snow that come with strong winds, leading to virtually zero visibility and significant hazards on the road.
These squalls can be especially dangerous, as they may cause severe injuries or fatalities when individuals exit their vehicles during such conditions. The NWS highlights a troubling history of traffic accidents tied to snow squalls, noting that even minor snow accumulation (generally less than an inch) can combine with fierce winds and rapidly falling temperatures to create perilous driving conditions.
Typically, snow squall warnings target specific areas and last between 30 to 60 minutes, similar to tornado or severe thunderstorm alerts. Currently, areas in Wisconsin are under snow squall warnings, as forecasters monitor the development of squall lines along a cold front that could also affect Chicago.
These squall lines can quickly lead to “whiteout” conditions, with road situations worsening rapidly due to snow bursts and wind gusts potentially exceeding 40 miles per hour. Video footage from Wisconsin illustrates the near-instantaneous reduction in visibility and accumulation of snow on highways during a recent snow squall.
Residents of the Chicago area should prepare for similar weather patterns, especially after sunset on Wednesday, when conditions may deteriorate swiftly. Forecast models suggest that precipitation could begin around 4 to 5 p.m., with brief but intense snow showers followed by plummeting temperatures that will drop from the upper 30s and low 40s to below freezing in a short span.
While major snow accumulation isn’t anticipated, the quick bursts of snow lasting 10 to 20 minutes could still create significant road hazards, combined with icy conditions. Moreover, the NBC 5 Storm Team advises that additional snow showers may linger after the front moves through, continuing to pose travel challenges.
This winter weather reminder emphasizes the importance of preparedness during challenging conditions. Motorists are encouraged to stay updated on weather alerts, drive cautiously, and consider postponing travel during anticipated squall warnings. By taking proactive measures, individuals can help ensure their safety and that of others on the road during this unpredictable winter season.
