Syracuse, N.Y. — The work week that started with rain and temperatures in the 40s will finish feeling colder than zero.
Wind chills Friday morning are expected to be below zero across most of Upstate New York, thanks to a high pressure system descending from Canada. That system will pull in cold air, and also push out clouds and allow warmer air to radiate into space.
The wind chill, which combines air temperature and wind speed to estimate how cold air feels on bare skin, will drop as low as minus 21 in the Adirondacks Friday morning.
“The main story will be bitterly cold temperatures and dangerous wind chills tonight into Friday morning, as an arctic air mass builds in,” the National Weather Service said.
Wind chill advisories are in place tonight and tomorrow on Tug Hill and in the Adirondacks, but the weather service warns that even though much of Upstate doesn’t meet the threshold for an official wind alert, people should avoid staying outdoors too long.
“The combination of cold temperatures and persistent wind will make tonight feel colder than it has been for quite some time,” the weather service’s Buffalo office said. “Frostbite and hypothermia can occur if precautions are not taken. Make sure to dress properly if you are planning to be outdoors during this time.”
High temperatures will rise into the 20s Friday and Saturday.
The high pressure system will also help keep a storm system sweeping across the South from having a big impact on Upstate New York. The storm is expected to graze Upstate with a dusting of snow along the Southern Tier, Catskills and Hudson Valley late Saturday or early Sunday.
The bitter cold follows a long lake effect snowstorm that dumped more than a foot of lake effect snow in areas downwind of lakes Erie and Ontario.
