Carvers Gap

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.

Are precip totals going up on the short range models at 12z - both NAMs and RGEM?

TRI gets hammered by the 12k NAM. There are considerable differences between the 12k and 3k regarding Chattanooga and TRI. I simply refer to you all who live in those places to know your microclimates. @nrgjeff- maybe he will stop in this afternoon. No doubt he is busy!

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

I pretty much knew when the 12z 3k NAM just rolled....it didn't leave them with a lot of wiggle room.

I love this quote, "Luck cannot be part of your safety protocol." Modeling overnight looks relatively consistent to yesterday. The 6z GFS has zero support so far. Story continues to look like ice in the northern valley.

Anyone know when we can start to see if reports on the ground match what modeling has....might helps us to know which model is initializing better and is more accurate?

Kind of impressive to see how much colder the ICON is through 38....3-5 degrees over E TN. Fits the trend of models correcting colder as the event gets closer.

Both 0z ICON and NAM are colder than their previous run through roughly 27....2-5 degrees depending on local.

Out to 27...2-3 degrees colder over E TN than its run at 18z.

Globals are not warm for next Thursday. I agree w/ @tnweathernut and others that this is a time to watch. It is very rare to get that type of cold without precip on the front edge of that type of front. It happens, but about 90% of the time there is high ratio stuff when this rolls in. Real feels. Again, with some snow under that...some locals may make a run at record lows which I thought were pretty safe. The GEM is the "warm model." Now let that sink in.
