So every model has central valley with. 25 to. 50 ice but still no updated advisory. 

MRX is working on that now. They are deciding which counties need an advisory and which need a warning. It should be out in a few minutes I think. They are also looking at the wind and what needs to be said about that.

My current take: The players:   The setting: the game: All in motion on the Euro       Comparison:   Euro trend:

Reb
Reb
John1122
John1122

I feel like this is a trap. I'm having 2017 ptsd from when the Euro showed 30 inches imby 48 hours out, and I ended up with two inches.

For east tn folks, this setup is where know your climo plays the biggest. Like I know that Tellico has realistically less than a 10% chance of significant icing (just way where situated), I know if I drive 5 mins up 68 into the Notchey Creek/Mt Vernon area their risk grows substantially (past history of power going out there in ice setups)

NOAA just posted a winter storm warning for most of East Tennessee up to 3 inches of snow and up to 4/10 of an inch of ice

They are slow updating the map, but it’s winter storm warnings, ice storm warnings and winter weather advisories

This seems reasonable and smart. The western side of the great valley is likely the area where cold won't scour easily so Ice Storm Warning makes sense, the mountain counties are still covered by WWA and northern areas with Storm Warning.1da52965ad62fbcdbaaf221ea05b0ea2.jpg

Me in Halls vs Knoxville is like I’m in a totally different county. I will not be surprised if my snow totals are closer to the counties to the north then south of me.

Honestly think should have used the nw zone of Monroe Co for ice storm warning

This scares me more than anything. Just a little bit of ice at the bottom of the mountains. There could be catastrophic tree damage.

With the way technology is now and social media with getting warnings and advisories and stuff like that out, I’m surprised the national weather service hasn’t gone to more of a polygon system with winter weather than still using counties. I understand why you use counties for severe thunderstorm watches, and tornado watches, flood watches… those kinds of things. But there’s multiple counties in East Tennessee that that can have a wide range of winter weather depended upon the location in that county. North of interstate 40 in Knox County just about always has a location advantage over areas south of interstate 40 when we have these 50-50 type systems. In these close call winter systems, my weather in Halls is always closer to the weather in Southern Anderson County, Southern Union County and southern Granger County.

This is going to be something… ice storm warning and I might not see any frozen precip.

It’s better to have the public in that county informed of the potential rather than no Notification and then get hit with ice

The 12z NAM put 1.88" of ice over Chattanooga.  No idea if that is right, but man.

My question is whats the air temperatures at the surface for the majority of this event? If they’re only about 30 to 32° then I don’t see there being any road issues. elevated surfaces trees, vehicles, house gutters, etc… we’ll have ice on them, but in my opinion with the warmer temperatures the last couple of days, I think the temperature is will need to be (IMO) 28° or below before we start having road issues.

It has been my experience with these things that it may well depend on which roads get a lot of sun and which don't regarding roads.  I know they started pre-treating yesterday here.  Our road crew guys have somebody who is good with weather.  They didn't wait for the warning packages.

It also largely depends on the rate of precipitation.  If it is pouring rain, it’s not going to freeze.  However, if it’s light rain/sprinkles, it will freeze pretty quickly after contact.

….. that’s a great point about the rain rates. Some of the worst road conditions I’ve ever been in was freezing fog.
