A potent Pacific cold front will surge through NM Tuesday with an intense burst of snow, strong winds, and blowing snow. Snowfall amounts of 2 to 5" are expected in around 12 hours along west-facing slopes of the northern mountains. Snow with wind gusts of 60 to 70 mph may lead to whiteout conditions at times in the northern mountains. Folks traveling along I-40 across western NM Tuesday morning may encounter rapidly deteriorating weather conditions.
