As new Arctic air enters the United States, NWS meteorologists warn about the “most intense” snow storm of the season.

A major winter storm slammed the US Gulf Coast Tuesday, blanketing parts of a region largely unaccustomed to extreme winter weather with record-breaking snowfall.

A major winter storm prompts blizzard warnings, dumping heavy snow and sleet in a region where even flurries are a rare sight.

A rare winter storm churned across the U.S. Gulf Coast on Tuesday, breaking snowfall records more than a century old in a southern region where flurries are unusual, as much of the United States remained in a dangerous deep freeze.

A rare frigid storm charged through Texas and the northern Gulf Coast on Tuesday, blanketing New Orleans and Houston with snow that closed highways, grounded nearly all flights and canceled school for more than a million students more accustomed to hurricane dismissals than snow days.

For example, Lake Charles, La., along the Gulf Coast, showed snowfall rates of over 1 inch per hour this morning and early afternoon and visibility down to a quarter of a mile with blowing snow. This is one of the reasons why blizzard warnings were posted briefly for that region earlier.
