A Winter Weather Advisory is in effect from 9 p.m., Friday, until 10 a.m., Saturday, with accumulating snow of up to 1 inch locally north of Interstate 40.
If you are traveling north of Wilson County to near the Tennessee-Kentucky border, be aware that up to 2 inches of snow is expected there.
Meteorologists with the National Weather Service Office in Old Hickory said an upper level disturbance is expected to move across the Mid-state and Kentucky Friday night and into Saturday. While areas north of I-40 are expected to see up to 1 inch of snow, areas south of the interstate will likely see less than one-half inch of accumulation.
Most of the snow, meteorologists said, is expected to fall later tonight with temperatures in the 20s. Roads will become covered with snow and will be slick. The snowfall is expected to taper off by about 10 a.m., Saturday, and travel conditions should improve by the afternoon as temperatures rise above freezing.
The NWS said, “A Winter Weather Advisory means that periods of snow will cause travel difficulties. Be prepared for slippery roads and limited visibilities, and use caution while driving.”
Another weather system, a low pressure area, is expected to develop around the Gulf Coast area on Monday and Tuesday and may bring another chance for a wintry mix.
Stephen Spencer, planning division chief with Wilson County Emergency Management Agency, said in a Weekend Weather Impact Briefing issued Friday afternoon, “There remains a great deal of uncertainty right now in terms of timing and placement of any winter weather impacts, but the overall pattern suggests an active period for potentially some winter weather.”
