How cold is it in Dallas during the polar vortex?

Dallas is experiencing extreme cold conditions with temperatures at approximately 19 degrees Fahrenheit, but the wind chill makes it feel like just 2 degrees. The severity of this cold snap is highlighted by CBS News correspondent Omar Villafranca, who points out that it's actually warmer in Reykjavik, Iceland and Anchorage, Alaska than in Dallas, Texas. This unusual weather pattern is part of a polar vortex affecting multiple states, creating hazardous conditions and raising concerns about energy consumption and rising electric bills across the affected regions.
