PowellVolz Posted February 4, 2021 Share Posted February 4, 2021 Hr 72-96 all winter long has had major changes occur at 500...this seems par for the course so far. Ride the ensembles until within hr 48. Seems like the last couple of years the Euro has been better 7-10 days out than 3-5 days out. . Link to comment Share on other sites More sharing options...

tnweathernut Posted February 4, 2021 Share Posted February 4, 2021 Out to 30, the energy coming at us is much stronger on the GFS in Idaho vs. the Euro. Yes, Idaho. This is the piece of energy that is set to make it to northeast TN in 42 hours. This thing is SCOOTING! I will say the energy is a tad more prominent than on the 0z Euro. Still doesn't look anything like the American modeling suite. Link to comment Share on other sites More sharing options...
tnweathernut Posted February 4, 2021 Share Posted February 4, 2021 Out to 48, it's TRYING to be better at 500. Energy trying to sharpen a bit in north Texas and western Oklahoma Link to comment Share on other sites More sharing options...
tnweathernut Posted February 4, 2021 Share Posted February 4, 2021 Surface responds between 54 and 60, with precip breaking out across Arkansas in the form of rain and snow north of there. Also much more precip in the deep south. This is definitely going to be more like the GFS Link to comment Share on other sites More sharing options...
tnweathernut Posted February 4, 2021 Share Posted February 4, 2021 Don't think this will be anything like the GFS suite, but it's a big step toward it. Just goes to show somewhere in the middle won't work for most. Gets going a little later it looks. Link to comment Share on other sites More sharing options...

tnweathernut Posted February 4, 2021 Share Posted February 4, 2021 Mostly light rains across Tennessee, but changes to snow across much of east Tennessee. I don't think the snow maps will be pretty, but this is moving toward something for someone in TN. 3 Link to comment Share on other sites More sharing options...

Holston_River_Rambler Posted February 4, 2021 Share Posted February 4, 2021 I suck at them though. Almost always a given if I anticipate X change in a model, it will go the other way. 1 Link to comment Share on other sites More sharing options...

tnweathernut Posted February 4, 2021 Share Posted February 4, 2021 Will try to show you what I was looking at. It’s closer than I thought when watching it in real time...... at 500. First the GFS at 30, 54, and 66. The vort looks a little more pronounced than on the Euro. Also, you can see the speed of this rascal. By 66 it’s in a great spot for producing precip across TN and the surface shows that as a nice little snow. Now, the Euro at the same times. Very similar placements wrt timing. Maybe a touch sharper on the American modeling which likely accounts for more snow shown. Threat looks legit, congrats to the GFSv16, which has had this for a couple of days now. . 4 Link to comment Share on other sites More sharing options...

Carvers Gap Posted February 4, 2021 Share Posted February 4, 2021 NA view 500 sort map at 144 (animate it) is like a conveyor on the Euro. No idea if it goes to the para-gfs multi-day over-running event, but the set-up is almost there. Link to comment Share on other sites More sharing options...

Just have to hope it doesn’t get too amped and nail Louisville lol That's how I take it too. The thing is, at our latitude................ really............. the GFS and GFSv16 is about perfect. Nice vort pass, goes negative in a perfect place, and is moisture laden. If it digs more, the storm is likely bigger, but warm air advection likely makes this a Kentucky to Virginia snow storm vs a Tennessee Valley snow storm.

Carvers Gap Posted February 4, 2021 Share Posted February 4, 2021 I don't know. The SLP pops off Charleston, SC. It has plenty of room to correct northwest. Would likely mean the entire storm spins up and we could have a very potent inland runner. Confluence would be earlier which could really force that thing to go neg tilt. tnweathernut is far better with that stuff than I! 1 Link to comment Share on other sites More sharing options...
