2/14- 2/16 Winter Storm and Arctic Cold
Holston_River_Rambler replied to WestTennWX's topic in Tennessee Valley
The Euro OP seems to be wanting to sharpen and dig the energy more, over the N Gulf. I tried to make a gif, but t is hard to get the time stamps synced because teh 6z/18z have different set of hours than the 0/12z runs. Here's an example though: More open, neutrally tilted wave: deeper, sharper, negatively tilted wave: the deeper that digs and the more negatively it can tilt, especially if it does it right along the MS river, the better for us all. -

Just from the perspective of "how do numerical forecast model services depict precip" perspective, it is interesting to see the diff. between the RGEM on TT and the RGEM on pivotal Hour 63: Here's the RGEM sounding that Pivotal gives over my general area for that time: -

Overnight Euro OP for western areas. I know Jax already shared teh specifics, but notice the "Max" number on the image. How manyt times will you see that number at hour 120 over the SE (and not the Apps?) -

Overnight Ukie takes the early week system's surface LP east of the Apps : Then the systems keep on coming. -

Got some freezing drizzle up here in Morgan County, and maybe a very melted snow flake or two mixed in. -

18z Euro: The energy looked rather RGEMish to me, if a tad west. -

18z RGEM keeps a week surface low entirely east of the Apps, and runs it up through the midlands of SC and NC: -

I'll go ahead and say that most EPS members (at least as they depict snowfall), are a much more west, but n=maybe we can apply rule #5 here: Euro tends to hold energy back. -

Sorry, I should probably keep the info for the early week system in this thread. That being said, check out the 18z GEFS members -

Man its 33 and change here at the edge of the plateau. As is the custom, fog has built in over the last couple of hours as some WAA tries to set up. -

Euro is going for a wave riding the front scenario as the trough digs and sharpens: doesn't generate a lot of precip this run, but if there's one thing we've had luck with the past couple of winters, it's that scenario. -

Memphis and Tobie ought to like the UKMET precip maps for Tuesday. And @Carvers Gap it could have some shades of the CMC's evolution. -

Even if a lot of this is sleet, I'll take it, lol: We'll see what the precip type amounts look like once they are available on F5wx. Look at that blue dollop over @PowellVolz !!!
