Freezing Rain, Plummeting Temps Sunday: HV Winter Storm

Get ready for the deep freeze. While the major winter storm continues to move out of the Hudson Valley, it is leaving behind freezing rain and sleet in some areas.

Temperatures will be plunging over the day Sunday and that will make any leftover snow, sleet and, if it's warm enough, puddles of water to freeze solid. That will be extremely difficult to shovel, as you can well imagine.

Plus the arctic blast will be accompanied by strong winds, meaning that all of the Hudson Valley, except for southern Westchester County, will be under wind chill advisories.

They are in effect from 1 a.m. to 1 p.m. Monday for Rockland, Putnam, Orange and northern Westchester counties.

For Dutchess and eastern Ulster, the wind chill advisory is in effect from 6 p.m. Sunday to 6 p.m. Monday.

Southern Westchester could have a flash freeze when the temperatures go below freezing.

Hudson Valley Weather said that there will be a few more rounds of precipitation — additional snow, sleet and freezing rain — through the morning hours.

"Any remaining snow, ice and standing water will flash freeze and become nearly impossible to deal with," HVW said.
