With Middle Tennessee residents buckling down for the coldest period so far this season, winter weather will likely hit with a vengeance today.
The National Weather Service predicts light snow – up to one inch – with accumulation expected during the morning west of Interstate 65 and east of I-65 through mid-afternoon.
The threat of “potential inclement weather” forced the closure of many midstate school systems  including Metro Nashville on Thursday.
The predicted snowfall will precede an Arctic cold front that will move east to west across the Nashville area this afternoon and send the mercury down sharply late tonight.
Low temperatures are expected to dip to 9 degrees on Friday night and 8 degrees on Saturday with high in the low 20s both days.
Behind this frontal passage, winds will be shifting to the west and then to the northwest becoming gusty as the afternoon progresses, according a NWS forecast.
All of Middle Tennessee is under a winter weather advisory until 6 p.m. today, and a wind chill advisory will be in effect from 6 a.m. Friday to 6 a.m. Saturday.
A wind chill advisory means that very cold air and strong winds will combine to generate the low wind chills.
Wind chill temperatures are expected to drop to around zero Thursday night and as low as minus 5 degrees Friday night.
The NWS urges residents to take precautions this weekend to protect life and property from the cold conditions.
