New Year’s revelers in Times Square should pack a poncho

Oh, what a difference a year makes, at least for outer wear for New Year’s revelers tonight in Times Square.

Instead of donning parkas to withstand a wind chill of 5 degrees below zero — as they did last December 31 in New York City — the party crowd this time will turn to ponchos for what will feel balmy in comparison.

While the Great Plains and West will feel the effects of a cold storm, much of the mid-Atlantic and South will cope with moderate winter temperatures and rain, according to forecasters.

“How can it be 10 degrees warmer in New York City than Phoenix on New Year’s Eve?” asked CNN meteorologist Chad Myers, adding that it will feel like 50 degrees in the Big Apple. “It will be one wave of rain after another.”

Snow, ice and rain are forecast for northern New York, Vermont, New Hampshire and Maine.

A complex storm system will bring a “plethora of impacts” from the Rockies to the Northern Plains and Upper Midwest on Monday, potentially making travel dangerous, the National Weather Service said.

“This arctic boundary will cause temperatures to plummet through the day across parts of the central Plains as wind chills reach hazardous levels from Montana through Nebraska” into Tuesday morning, forecasters said.

The weather service warned blizzard conditions will bring reduced visibility for motorists in the Dakotas and Minnesota. “Conditions will gradually improve from north to south throughout the day. Be prepared for hazardous travel due to the reduced visibility and snow/ice covered roads, in addition to hazardous wind chills.”

Another front is expected to bring “significant snowfall” to parts of Arizona, Colorado and New Mexico, where some areas could get more than 10 inches of accumulation.

The expected high in Las Vegas will be 44.
