Severe Cold in the Forecast for Yorktown

SOMERS, NY — The snowflakes have come to an end for the Hudson Valley as temps rise above the freezing mark and rain ends by early Monday afternoon.

The rest of the weather week looks calm on the precipitation front except for a chance of some more snow on Friday night and Saturday, and that too could mix with some rain.

The big story will be the blast of arctic air moving through the Hudson Valley toward the end of the work week that will keep high temperatures in the low 20s — feeling even chillier with the wind.

"The cold will be severe enough to bring the risk of frostbite or hypothermia to those spending time outdoors without proper clothing," said Renee Duff, AccuWeather meteorologist. "Residents should ensure pets have proper shelter and limit their furry friend’s exposure outdoors. Vehicles may need to be inspected for problems that can arise during extreme cold and residents should ensure that an emergency preparedness kit is handy in case of a break down on the highway."

Temps will be in the single digits Thursday night.
