"Arctic Blast Brings Early Winter Chill Across the US"

A widespread cold snap is moving across the Lower 48, bringing the coldest air of the season so far. Many areas could experience their first frost or freeze, and several cities may break daily record lows, particularly on Wednesday and Thursday. The cold air is originating from a strong high-pressure system stretching from western Canada to the Plains, and it has already reached as far south as Texas and as far east as the Great Lakes. Frost and freeze alerts have been issued for parts of the Southwest, Midwest, Southeast, and interior Northeast, with more alerts expected. Over four dozen locations could be within a few degrees of daily record lows.
