Winter Weather Advisory in Effect until 7 p.m. Today

The National Weather Service has extended the Winter Weather Advisory until 7 p.m.


Posted at 10 a.m.

The National Weather Service (NWS) has issued a Winter Weather Advisory until 1 p.m. today for a wintry mix of snow, sleet, and freezing rain. Please use caution while driving and stay off the roads if possible this morning.

The NWS uses specific winter weather terms to ensure that we know what to expect during a winter storm. Here’s what NWS means when you hear these terms:

  • Winter Weather Advisories inform you that winter weather conditions are expected to cause significant inconveniences that may be hazardous. If caution is exercised, advisory situations should not become life-threatening.
  • Winter Storm Watch means that severe winter conditions, such as heavy snow and/or ice, may affect your area, but its occurrence, location and timing are still uncertain. A winter storm watch is issued to provide 12 to 36 hours notice of the possibility of severe winter weather. A winter storm watch is intended to provide enough lead time so those who need to set plans in motion can do so.
  • Winter Storm Warning means that 4 or more inches of snow or sleet is expected in the next 12 hours, or 6 or more inches in 24 hours, or 1/4 inch or more of ice accretion is expected.
  • A Blizzard Warning means that snow and strong winds will combine to produce a blinding snow (near zero visibility), deep drifts and life-threatening wind chill. Be sure to listen carefully to the radio, television and NOAA Weather Radio for the latest winter storm watches, warnings and advisories.
  • Freezing Rain – Rain that freezes when it hits the ground, creating a coating of ice on roads, walkways, trees and power lines.
  • Sleet – Rain that turns to ice pellets before reaching the ground. Sleet also causes moisture on roads to freeze and become slippery.
  • Frost/Freeze Warning — Below freezing temperatures are expected.
  • Wind Chill — One of the gravest dangers of winter weather is wind chill. The wind chill is based on the rate of heat loss from exposed skin by combined effects of wind and cold. As the wind increases, heat is carried away from the body at an accelerated rate, driving down the body temperature. Animals are also effected by wind chill. Check out the wind chill chart at

    This was helpful. I did not realize until I read this post that these weather terms I hear on the radio are actually quite specific about conditions, and that a “warning” is not a “maybe will happen” but a “definitely will happen.” Thanks for clarifying.

    Advisory is until 6 am Thurs, not 1 pm Wed

    Well can we get some liberal leave or be closed?!? This weather is dangerous for driving. I live across the mountian and am not very fond of the fact that I have to drive home this evening in icy/snow conditions.

      Amanda – the county has not announced its operating status for tomorrow. If there is a change to normal operations, it will be announced on this blog and through the local media.

        I understand. I’m also talking about this afternoon, I’ve talked to multiple family members that have told me that it is still snowing and some roads have not been treated where I live (clarke county) and also have heard reports on multiple accidents on the mountian, in the past when we have had weather like this we’ve been released early from work which I think should happen today. I get off at 4:30 & it takes me about a hour to get to the mountian which temps will be dropping at that time and roads will be starting to freeze over. As a safety concern I’d like for me as we’ll as other commuters to be able to get home safely before roads start to freeze.

    What about the Health Dept clinic that runs from 5PM-6:30 PM at the Joseph Willard????
    We usually go by school closures however they are on holiday break.
    Should we ask our staff to come in or not??
