    Wouldn't be the first time. Won't be the last time. Re below: Yeah some models have a little back side. Chatty won't get anything that set-up, but it could be a nice little all-snow dessert at the end for points north and east.

    FZRA and 30 here but not adding any ice in East Brainerd, Chattanooga. My guess is the ground picked up some solar insolation through the clouds. Metal is getting some new ice but even the bushes are not accruing. We'll see how it goes after sunset. It's going to be a buzzer beater, since I'm also watching a ton of basketball. Warm nose or CAD wrap? That's for the current wave. Sunday looks safely rain in Chattanooga until the very end and light. As we cautiously let our guard down east, keep those out west in our thoughts. Many places that had sleet have switched over to FZRA. It's moderate and with several hours to go; then, round 2 tomorrow.

    End of the month system still shows up on GFS and AIFS Euro AI. Other ensembles are of course all over the place. That'll also have implications on the High Risk for much below normal temps from CPC.

    Memphis looks to keep mostly snow and sleet this first wave. Concerns remain on Sunday. Reliable models are split between more sleet or a slug of freezing rain. Nashville is of course subject to everything running cold. Several hours of all rain off ramp is in jeopardy. Sleet remains an exit ramp. Otherwise, major ice storm there - continuation of North Miss to southern Mid-Tenn. Chattanooga will stay ice longer than forecast into tonight. CAD is c0ck blocking the warm nose.

    I want to make sure that's not Barrons Wx. Their official page is good. They were a major pioneer in weather radar display for commercial use. Much respect! I'm just struggling with his forecasting lane.

    Chattanooga is all freezing rain. Light at the moment - mercifully. No more sleet. Radar above confirms it's all rain aloft. QPF is going to be all ice until sometime this evening. Temps are way under forecast and cooler models keep it below freezing until later in the evening.

    Yes @Knoxtron that's the line, but keep in mind it's aloft. Surface manifestation can vary. Also with ice it's not a clear rain/snow line. Otherwise all snow north of it right now. Mixed variations of pain south of it. My driveway in east Chattanooga mostly thawed thanx to apparently enough solar radiation coming through the clouds. Temp is 30. Couple hours ago I thought my glacier of the week had started. Plenty more frozen precip is incoming though. BTW is this gonna be the obs thread? We have a pinned forecast thread.

    Bless BAMs heart the Euro, NBM and everything else knew also. If they think nobody knows about other models.. shit! Meanwhile I'm up for jinx post of the year.. CAD never wraps around in winter (CHA). Only when I want to chase storms it stabilizes things. Revised rules. CAD wraps around only when I don't want it; kills storm chances, promotes ice. When I want help for snow it fails. KCHA is running a couple degrees (or more) below guidance. Still think we'll thaw Sunday, but I'm gonna need power through Saturday for college hoops on TV!

    Could be in places on the bubble, re sleet vs FZRA. Love the Bon Jovi reference. Rock on!

    00Z follows 18Z colder than earlier runs. Damn! Hoped 18Z was just a blip. Perhaps I jinxed Chattanooga several pages back with.. I'm not too worried locally. CAD only wraps around when I want to chase storms! Welp. We'll see about that on Saturday. Joking aside, all this does is increase confidence in a devastating ice storm from the Mid-South to Mid-Tenn. This is a truly upper end event. Models are split on the sleet vs FZRA question in MEM. Most reliable short-term ensemble favors sleet. Same NAM. Couple of the newer hi-res models FZRA. Then for BNA the colder temps simply boost FZRA amounts. MEM is living on the edge between damaging and truly catastrophic. BNA is just living on the edge I guess. Then up in northeast Tennessee, y'all in the microclimates gotta take it from here. Good night and be safe.

    Broadly, the case for the warmup is a robust southern flow. This is much stronger than a usual winter system. Column is TOTALLY saturated up to 400 mb or higher, offering little chance for evaporative cooling regardless of how strong the lift. Recon actually helped models key in on the kinetic strength and moisture depth. I don't wanna be the downer, but we always knew it could go either way. Went warmer. Also remember in the day 8-14 range CPC highlighted this as a Heavy Rain event. Well, we're almost full circle.

    MRX ice chart looks reasonable to me. I have not looked at microclimates north of say Cleveland, Tenn. Generally seems to get the downslope foothills and cold stuck a little north side of Great Valley. I like it a lot around Chatty and surrounding mountains. GFS is too far south. I am not at all concerned about its local ice forecast. RAP might as well plant a Quebec flag in North Mississippi. Quebec basically has the North American ice storm of record from 1998. No I don't believe that's in the cards, but MEM 1994 (displaced south) could be.

    Bigger problem for North Georgia. In spring (when I wanna chase) it curls around and stabilizes everything. In winter the warm nose usually wins. Hey @jaxjagmanwe do have Day 3 Marginal in South Bama and text mentions tornadoes!
  14. nrgjeff
    Yeah the model ice forecasts are not great this set-up. One has to manually look at QPF and dissect which of those periods are below freezing. I get lower ice in Chatty than NWS. I get higher Knox northeast. Lee side foothills downslope? I give up!
  15. nrgjeff
    That scenario makes a lot of sense in Chattanooga. Knox and points north could have more light precip. Sunday night. In this business anything is possible for both locations. We'll know Monday morning.
