  1. Brief mild period late next week makes sense ahead of the weekend cold front. Keep in mind AN temps in January is still cold. New convection in the IO may be crossing Indonesia at the time... but propagating on to the West Pac. Then we set up a return to Alaska ridge and perhaps North Atlantic help. Normally I'd be really skeptical of the MLK Day week forecast; however, it is peak climo. We need to reel that sh!t in including southeast Tenn.
  2. NFL weekend is going to be nuts! After being robbed in Cincy (Refs setting up last week excitement) KC looks for home field. KC's fate depends on Houston. Alas, that's the Titans game! Honestly Tennessee deserves home field, but of course I also have KC interests. Finally Las Vegas and the Chargers Sunday night, win and in, lose and go home. Can't stand the Raiders. Go Chargers!
  3. Carvers nails the serious weather discussion above. MJO and Tele-connections are supportive. To strengthen the thunderstorms to snow method, we're going to need tornado watches with the MLK Day weekend system. Then we can have snow in the 11-20 day, lol!
  4. Welp. At least the ECMWF weeklies are cold out three weeks. Keep trying. Might keep throwing bricks. Maybe hit some baskets.
  5. Knoxville zig-zag heartburn update.. Should only last another hour. Hard to see Knox radar but Hytop shows better CC trends. Line is finally dropping south on the Plateau. Should translate east. Remember this is not an elevation problem. It's the storm track. Can't promise anything south of there, but Knoxville should barely hold on snow.
  6. Going back and fourth another 90 minutes in Knoxville, in infer from CC loop. Gut says switch for good, just in time for rush hour. Schools enjoy your 4-day weekend!
  7. Athens reports are disheartening regarding the warm nose; however, this is a storm track issue more than an elevation issue. Athens is higher than Knox, but Knox is in a better spot relative to the storm track. Radar in Middle Tenn is filling in better than I'd imagined. Still light, but not zero. Certainly it's better than the CAMs had depicted with the hard shut-off. North Alabama visible satellite is bumpier than I'd expected by now - a sign of continued lift or at least multi-layered clouds. Both trends are favorable where it's currently snowing. For those in the warm nose, join me and the Dark Side. Let your anger flow through you. We Sith can hope for severe weather next time. This system would be a warm front tornado machine in March.
  8. Nashville is mighty close to the dry slot. Southern 840 suburbs are probably about done. Downtown north could get clipped with what little back side this system offers. Meanwhile MRX is growing more confident about Knoxville. Mentions snow and ice covered roads evening rush hour Knox to TRI. Warm nose is trying, but I-40/I-81 are simply in a better position with this storm track than say Chattanooga. Or Signal Mtn. Oof!
  9. Correlation Coefficient bright band diagnostics looking at both Nashville and Huntsville radar... West of I-65 snow line is trying to move south, as expected on the back side. Carry on Nashville! Hammer time Upper Plateau! Bright band is trying to hold over KCHA (our mix) but appears warm air is nosing up too. Knoxville is going to be close. Gut says 850 T drops back side before moisture departs - some snow Knox. Like Vols basketball, you have to sweat it out before the win! Can't imagine the TRI Cities busting here. Only concerns are the usual local orographics. Gotta take turns.
  10. Snow in northwest Alabama again. I need to be in the Shoals for snow and severe.
  11. All rain East Brainerd. KCHA reports sleet and 40, but no pellets at my location. When's the next chance of severe weather?
  12. MRX just updated. Knox may start as rain. Quick change to snow. Esp north of I-40. Knox proper will be fine. AFD does not show it yet, but they just wrote it to EMs.
  13. As @dwagner88 said we are getting ready for our rainy day in Chattanooga. I doubt any snow later. Initial sleep pellets will be it. Signal and Lookout could get some snow, but I bet less than last time. Knox to TRI axis is a little better relative to the track. Warm valley may be an issue, but I figure snow falls up there later. Regarding 850 Ts it's probably accurate because they do have aircraft. MD drawing even acknowledges the situation with the kink southeast side of the blob. Today is fun for Western and Middle Tennessee, esp Middle. Enjoy the snow!
  14. I wouldn't worry about that 18Z NAM. HRRR run off the same WRF is in line with the GFS/Euro. Upper Plateau is staying all snow. Bank on that! Tennessee has sports bettering. What about weather betting? Though I have not looked hard, Kentucky snow looks excellent. PVA is lined up. Should be plenty of overrunning moisture up there. Last post today. You all know my Chattan00ga forecast. No snow in the valley. Wins for Signal and Lookout. Mocs beat Wofford tonight.
  15. Re the vort max: Fortunately the flatter / less amped kind of offsets the north. They both keep similar results at the ground. Chattanooga border war. Elsewhere I still think the Upper Valley will be fine, barring a particularly brutal energy transfer debacle. My gut says it'll be OK. Advisories hoisted from North Mississippi and North Alabama northward. MRX will decide in an hour, situated in Eastern Time.
  16. Arctic air situation qualifies everywhere but Chattanooga, lol! Long as the vort max is north we have warm nose risk. Downslope is not as much the issue with northerly rather than easterly winds. Meanwhile the ECMWF is steady. Keeps almost all of Tennessee involved. For Chattanooga see above. Signal and Lookout are good. Oh wow! Kingsport heartburn never ends. Do we cue up Metallica? My Friend of Misery.
  17. Forum needs a glow sticks rave emoji for a forecast like that above. Reality is that along and north of I-40 and I-81 all systems are go!
  18. Regarding last post page 7. Chattanooga proper might score two busts in a row. Looks fine for the rest of East Tenn. Barring a hand-off debacle I think all of the TRI should be fine. ICON follows GFS with Chatty winter precip. Prepare for disappointment in the valley. I'll double down. How about snow in Soddy and Ooltewah but not Downtown or East Brainerd? Signal and Lookout look solid though.
  19. Southern Valley warm-nose risk is mainly because the vort max is still north. With less of a defined low level low, downslope will not be the deal killer. Plus the dry air will cool with precip. But that vort max. HRRR is too amped though. We know it's always on steroids for severe. Well the physics of the model remains the same; therefore, one can deduce it's too amped. So the HRRR warm risk is too much. NAM is probably the worst case. Globals of course are all systems go! I feel pretty good about along and north of I-40 and I-81. South is TBD. Note the MRX lowest case still gets Knoxville snow. Shows the classic Athens north. MRX highest case gets Chatt. Official fcst looks reasonable. Nashville, Memphis, Paducah and Jackson, KY also have a public snow forecasts up.
  20. 1. Tri Cities should do better, or at least be more consistent @Carvers Gap. 2. I'm never excited about Chattanooga @dwagner88. Last post of the day. Cheers!
  21. So much to discuss. It does looks like a decent situation state-wide. 1. Sounding is from near the rain/snow line so yes it has a warm nose. What I'm seeing above that is a saturated DGZ. Looks like an isentropic lift event along all the right surfaces. 2. Chattanooga could benefit from dynamic cooling aloft; however, surface temps should remain mid-30s during snowfall if it snows. Signal and Lookout will be snow. 3. @8283 El Nino Baby welcome to Tennessee! Rose Bowl effect in Chattanooga today - I know that's Southern Calif. Chattanooga got blanked but snow sits on local mountains. I used to forecast for several California newspapers including the LA Times and San Jose Mercury News. California micro-climates rock! We will try to satisfy you here in Tennessee. 4. Yeah the banding on the Euro is probably forecast banding of snow. Of course those locations are subject to change. 5. There's still time for East Coast weenies. Our last system surprised them. Can we get two in a row in DC for Ian? As others have noted a less amped slider would really help Chattanooga proper. However it might put us in conflict with Memphis - where snow is quite possible this time.
  22. That's not bad right above. 1-2 West. My conceptual model has 1-3 most of Mid-Tenn, except far southern. Then 3-5 looks reasonable Upper Cumberland into Kentucky. Upper Great Valley should do better than last time. Chart looks similar at higher elevations with 6-8. KCHA remains a big warm nose risk. Signal and Lookout get snow again though. GFS below must be forecasting some banding. Not unreasonable, somewhere in the Region.
  23. I like the GFS/Euro blend. NAM is still probably too north the 12Z run. UK Met is with the other globals south of the NAM. Still blanks Chattanooga. However it looks really similar to Sunday night. Add more for Western Tenn. If we can get a more diffuse northern boundary then Kentucky remains well in play. Track may be broader north and west. South side (KCHA) still has warm nose issues. Also does not line up as well for North Alabama (still light snow but not nearly as much).
  24. Add the Florida Gulf Coast to places that get more snow than Chattanooga. NYC got hammered right after comparing itself to HSV. See what I'm trying to do here?
  25. UK and ECMWF join the chorus for I-40 and I-81 north on Thursday. Looks like all good straight east of Knoxville too. GFS has an odd southern solution; so yes, I'd go with the GEFS. OK in Chatty we are praying for the GFS Op. Cold air will be in place. Might not start below freezing, but it's not starting at 70. Starting around 40 is doable with an east wind, except for... you know. ECMWF weeklies in cold for three weeks. Could be a fun January. It has MJO support attm. AN rain Deep South and BN precip here is a good look. Snow holds less moisture.
