WIND CHILL ADVISORY: for the northern half of the Tri-States through noon Sunday. This is issued when chills are expected to be -20 or colder for at least three hours due to sustained wind speeds, not wind gusts. These are very cold conditions which could lead to frostbite to exposed skin in 30 minutes.

In as little as 30 min frostbite may occur to exposed skin. Make sure cars are packed with a winter survival kit and extra blankets.
Throughout the day temperatures will remain in the single digits north of Quincy and farther south in the low teens. Wind chills will remain below zero throughout the day.
While temperatures Monday morning may be just as cold as Sunday morning, the wind chills won't be as bad since the winds won't be as strong. However, they still could be as cold as 10 below. Keeping a close eye on a quick wave of energy that will be passing by throughout the day. Some models hint as to some light snow accumulation for some, however, dry air at the surface will likely keep that from reaching the ground.
