As travelers embark on their journeys for Thanksgiving, forecasters warn of a significant arctic outbreak affecting large regions of the country, particularly the northern Plains and Midwest. The National Weather Service (NWS) has indicated that areas could see temperatures plummet, reaching staggering lows from -30°F to -40°F (-34°C to -40°C). Reports suggest that heavy snowfall is imminent in the Colorado Rockies, with totals potentially surpassing 10 inches (25 cm) by Wednesday. This frigid front is expected to shift eastward, bringing with it severe thunderstorms and "lake-effect" snow across the Midwest and Great Lakes regions. By Tuesday and Wednesday of this week, the US Transportation Security Administration (TSA) forecasts record passenger activity, estimating nearly nine million travelers will pass through airports, with an additional 72 million taking to the roads, fueled by lower fuel prices compared to last year's holiday. So far, airport disruptions have been minimal. Still, drivers may encounter treacherous conditions on key highways, particularly I-90 and I-81.
