A substantial winter storm is wreaking havoc across extensive regions of the United States, causing icy winds, heavy snowfall, travel disruptions, and power outages for thousands.

The storm is anticipated to be succeeded by an intense cold arctic spell during the weekend, with temperatures dropping to nearly -50°F (-45°C) in certain areas.

Iowa, where the 2024 election cycle is set to commence on Monday, has experienced nearly 10 inches (25.4 cm) of snow, impacting campaign events.

The National Weather Service (NWS) has declared the weather conditions as "life-threatening winter weather," issuing alerts in nearly every state. Snow is expected to persist into Saturday, affecting areas from Oregon to Maine. Over 70 million people are under winter weather alerts.

More than 2,000 flights have been cancelled due to extreme weather, with Chicago being the most affected city. Approximately 200,000 people are without power, mainly in Michigan and Wisconsin.

Meteorologist Brian Hurley from the NWS stated that midwestern states, including Iowa, northern Illinois, and southern Wisconsin, have already witnessed six to 10 inches of snow by Friday evening.

The extreme weather has led to the cancellation of numerous flights and campaign events, including those of former President Donald Trump and other candidates.

Southern states are also expected to experience a mix of snow, sleet, and freezing rain, with Texas facing wind chill warnings and temperatures potentially dropping to -25°F (-32°C).

The bone-chilling arctic front following the storms is causing concerns about record-low temperatures, especially in Montana and the Dakotas.

Wind chill warnings ranging from -55°F (-48°C) to -35°F (-37°C) have been issued across the northwest and down to Nebraska and Kansas.

As the cold air moves eastward, the NWS predicts the likelihood of record-low temperatures in parts of the US, particularly in Montana and the Dakotas. Wind chill warnings have been issued across the northwest, down to Nebraska and Kansas, with life-threatening conditions expected.

Northern Missouri faces wind chills up to 35 degrees below zero, posing a risk of frostbite on exposed skin in as little as 10 minutes.
