A Winter Weather Advisory for all of Middle Tennessee, including Wilson County, has been cancelled by the National Weather Service Office in Old Hickory, but a Wind Chill Advisory remains in effect from midnight, Sunday, until 8 a.m., Tuesday.

Meteorologists still expect snow to fall later this afternoon and tonight, but said they are looking at up to one-half inch north of Interstate 40. The surface low expected to bring the snowfall moved too far north and the moisture was going away quicker than expected.

The Arctic front was still expected to move through Middle Tennessee and the Cumberland Plateau by around 8 tonight. Rainfall began falling shortly after 2 p.m.

Meteorologists were more concerned with plunging temperatures and wind chills later tonight and on Monday. Local school officials have cancelled classes for students attending Wilson County Schools and Lebanon Special School District on Monday and Tuesday as a precaution.

As the cold front moves through the Mid-state Sunday night, temperatures are expected to drop some 12-15 degrees per hour with lows overnight falling to low single digits by Monday morning. Roads will freeze rapidly, causing hazardous driving conditions later tonight and tomorrow.

In addition to the cold temperatures, winds out of the northwest will gust 30 to 40 mph tonight and in the morning, and with low temperatures in the single digits, wind chills will also be very low. Meteorologists noted that wind chills of minus 15 degrees to minus 20 degrees will not be out of the question. A Wind Advisory is in effect until midnight, Sunday.

Extremely cold temperatures and dangerous wind chills will continue on Monday and Monday night. The high Monday will be between 5 and 10 degrees, after a low overnight near 4 degrees.

They emphasized that such low temperatures and wind chills is dangerous and prolonged exposure to it should be avoided. Frostbite and hypothermia may occur if proper precautions are not taken. If you must go out, dress warmly, meteorologists said, with layers of clothing, and do not stay outside any longer than necessary. If you must travel, be prepared and take extra clothing and blankets.

Make sure all exposed water pipes are protected. Check on elderly neighbors to make sure they are safe and warm. Also, check on your pets, too. Weather conditions like what is expected here later can be dangerous for them as well.

There is a chance of snow showers then flurries on Monday and a chance of flurries on Monday night when skies will be mostly cloudy with a low near zero. Wind chill could be as low as minus 13 with winds west-northwest at 5 to 15 mph and gusting as high as 20 mph.

Tuesday will be mostly sunny with a high near 16 and a low Tuesday night of about 12. Wednesday will be mostly sunny with a high near 38. There is a chance of a wintry mix Wednesday night with a low of 28.
