A large arctic air mass remains settled over the Ohio Valley. Reinforcing shots of colder air have set up conditions ripe for some of the coldest temperatures of the season. As a result, any significant winds during the overnight period and Monday morning will make it feel even colder with sub-zero wind chills expected through the period. For that reason, a WIND CHILL ADVISORY is in effect until 10:00 am Monday for Fleming, Montgomery, Bath, Rowan, Estill, Powell, Menifee, Rockcastle, Jackson, Elliott, Morgan, Wolfe, and Lee Counties.
Single digit lows will combine with winds of 10 to 15 mph to drive wind chills below zero late tonight into Monday Morning. With winds of 10 to 15 mph, wind chills are expected to fall as low as 10 to 15 degrees below zero. Temperatures will warm up enough to bring wind chills above critical levels by 10:00 am Monday morning. A WIND CHILL ADVISORY means that very cold air and strong winds will combine to generate low wind chills. This will result in frost bite and lead to hypothermia if precautions are not taken. If you must venture outdoors, make sure you wear a hat and gloves.
