Southern New England will see the brunt of this quick-hitting system with Greater Boston expecting hefty accumulations.

Snow was falling in New Orleans, where as much as 8 inches were expected to accumulate by the end of the day, threatening to tie a record set in 1895.

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.

Winter storm warnings spread from Louisiana through Virginia on Tuesday as a winter storm hit the U.S. Southeast.
