The National Weather Service has issued a Winter Weather Advisory that will be in effect from 9 a.m. this morning (Dec. 16)  to 6 p.m. Saturday, Dec. 17, with a Wind Chill Advisory in effect from 6 p.m. Saturday, Dec. 17,  to 11 a.m. Sunday, Dec. 18.

Freezing drizzle is expected to develop by mid morning and continue into this evening. Some sleet could also occur. The freezing drizzle will change over to snow late tonight and continue into Saturday afternoon.

Ice accumulations of up to a tenth of an inch are possible. Snow accumulations from Friday night into Saturday will range from 1 to 3 inches.

Wind chill values will fall to 20 below by Saturday evening and 25 below Saturday night into early Sunday.

Surface temperatures will be below freezing, thus light icing accumulations can be expected. Icing is especially likely on untreated roads, sidewalks, parking lots, bridges and overpasses. When snow develops, north to northwest winds increasing to 15 to 30 mph could create areas of blowing snow.

The dangerously low wind chill values will cause frost bite to exposed skin in a short period of time.

A Winter Weather Advisory means that periods of snow, sleet or freezing rain will cause travel difficulties. Be prepared for slippery roads and limited visibilities  and use caution while driving.

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.
