Thursday, January 24, 2013 - 9:30 am

Arctic high pressure extending from southwestern Quebec across New York will continue to bring dry and very cold conditions to the North Country, with temperatures not expected to rebound much before Monday.

The cold perists in the St. Lawrence Valley, and the low temperatures are increasing the threat of ice-dam flooding, according to the National Weather Service.

The NWS has posted hazardous weather outlooks for wind chill and a flood watch.

Temperatures today will struggle to reach zero, and with winds as high as 15 mph will be driving wind chill values to near minus 30.

Temperatures tonight are expected to dip will into minus territory again tonight, approaching minus 20 with wind chills down to minus 25 or lower.

Today, at least, we have the compensation of sunshine, but that will disappear behind clouds tomorrow.
