Arctic Blast to Bring Snow and Ice to 30 U.S. States, Affecting 160 Million People

A powerful Arctic air mass is set to sweep across the United States, bringing snow and ice to nearly 30 states and impacting approximately 160 million people. The cold front is expected to intensify on Thursday in the Southwest before advancing to the East Coast over the weekend. Meteorologists anticipate temperatures plunging well below freezing in some regions as the Polar Vortex settles over the country.

Transportation officials, including airport authorities in several major cities, are warning travelers to prepare for significant delays due to the severe winter weather. The system is projected to develop in Texas and New Mexico, then move eastward, covering cities such as Memphis, Nashville, Washington D.C., Baltimore, Philadelphia, and New York with snow. States across the interior plains could experience temperatures dropping to -40°F (-40°C) or lower, while the Rocky Mountain states are expected to receive substantial snowfall by Friday.

Although exact snowfall totals in urban areas remain uncertain, some locations may see accumulations exceeding 12 inches (30 cm). Southern states might encounter freezing rain, potentially leading to ice-coated trees and power outages. The National Weather Service (NWS) has cautioned that wind chills could fall well below average, posing a risk of frostbite to exposed skin within minutes.

"With the extreme cold temperatures, expect prolonged snow and ice impacts which may include hazardous travel conditions, power outages, tree damages, snow-covered roads, and reduced visibility," the NWS stated in its forecast.

Governors in several states, including Texas, North Carolina, and South Carolina, have declared states of emergency, enabling emergency officials, including National Guard troops, to begin mobilizing response efforts. Texas Governor Greg Abbott emphasized the state's proactive measures, stating, "Based on current forecasts, the State of Texas is acting to ensure Texans have the resources they need before severe winter weather impacts communities across Texas."

The warnings come amid memories of the severe winter storm that struck Texas in 2021, causing the energy grid to fail and leaving millions without power for several days. Officials caution that the impending cold temperatures could again cause pipes to freeze and burst, and roadways may be blocked for days, especially in southern states with limited de-icing equipment. Cold temperatures are expected to persist into next week.
