A wintry mix early Monday-Updates

Hour By Hour - Today.png

11AM Update:

NWS has extended the winter weather advisory for most locations till 1pm. The reason is that the cold air is having a difficult time trying to move out overall. While some of us have warmed to above freezing, several higher elevations and pockets in the valleys are still around freezing. At the same time, light rain/freezing rain continues to fall.
Still think all will go above freezing this afternoon and ice should melt.
Seems on average most saw up to .10" of ice, with around .08" in Chattanooga. Need about .25" to start doing damage to trees/powerlines.

9AM Update:

Rain letting up in NE AL, hope that will allow warming and melting of ICE.
Still slick spots, however @TrafficTracker9 tells me not as many accidents in last hour. All slowly transitioning to ALL rain.
Not expected a refreeze tonight as we stay above freezing.

7AM Update:

Now that temps have fallen and more precip is moving in, we are getting numerous reports of slick roads and numerous accidents. Temps will hold steady around freezing for the next couple hours. Hopefully a transition to all rain by mid AM, however isolated spots and higher elevations (Lookout mountain is at 26°). Radar/info in pics.

5:30am UPDATE:

More precip now reaching the ground with sleet/rain in Chattanooga, and many locations west. Note in the pictures, the "colder" spots. Need to watch this areas closer. Impacts not that of a major ice, but slick spots likely!

Still looking at 4-6hours of mixed precip/freezing rain before a switch to all rain later this AM.

We do have the possibility of a light wintry mix for Monday Morning, then gradually changing to rain. A big warm up should also begin for the remainder of the upcoming week.

We will be closely watching a system moving in from the west which should bring some precipitation back to the Tennessee Valley starting late Sunday Night and into Monday Morning. Amounts should be light initially as the moisture battles the dry air in place. Also, temperatures during the night could drop back to right around freezing. So, we could have some periods of freezing rain, sleet and even light snow to begin with during the predawn hours. By sunrise and afterward, temperatures ALOFT should rise above freezing. Then, slowly, the temperatures at the surface should rise above freezing later Monday Morning. Due to our viewing area having different elevations and colder valley pockets, the rate of change could be slower for some. So, there could be some slick roads initially Monday Morning, then slowly becoming just wet as temperatures reach around 40 by the afternoon. It Could take longer for areas east of I-75. As always, the StormTrack 9 Team will be watching this system through the weekend, so stay tuned for updates!

A chilly rain should end through early Tuesday Morning. Then, a milder weather pattern with afternoon highs much more seasonable in the 50s for mid/late week. 60s are not out of the question by late week! So, Winter is FAR from over, but at least a thaw could be on the way!
