SARANAC LAKE — Frostbite could set into exposed skin in as little as 10 minutes as it gets dangerously cold and windy again Friday and Saturday, forecasters warn.

The National Weather Service has put forth a wind chill watch from late Thursday night until Saturday evening for most of northern New York, including Franklin, Essex, Clinton and St. Lawrence counties. Wind chills could range from 25 to 45 degrees below zero during that time, NWS forecasters say.

Without wind, temperatures in Saranac Lake will drop from highs of 19 today and 17 Thursday to 11 degrees below zero Thursday night. The high temperature Friday is only supposed to reach minus 7, dropping to minus 22 that night. Saturday’s high is predicted to reach only minus 11, dropping to minus 24 that night.

The deep freeze is supposed to lessen Sunday with temperatures reaching 12, dropping to 8 that night. Monday and Tuesday are supposed to be relatively balmy — by recent standards, at least — with highs and lows in the 20s.

Because of the cold weather, the Saranac Lake nordic ski teams will not attend a big annual meet in North Creek Saturday.
