Was hoping to get to at least 3 or 4 this afternoon before going over to sleet but I'm not so now. Same. On the phone with my sister in athens and they just went to sleet 1 Link to comment Share on other sites More sharing options...

The webcam from Hartsfield International Airport: https://www.fox10phoenix.com/webcams-atlanta2 I'm near Charlotte-Douglas International Airport on the Southwest side of I-485 beltway. CLT Airport likely to look exactly like Hartsfield-Jackson Atlanta International Airport in a few hours. Metro Charlotte will likely see mostly snow with 2-3 inches with a change over to a wintry mix with snow/sleet towards the end. However, it'll likely briefly turn back to light snow before the precipitation ends. I think too many models and forecasters are overestimating the northward movement due to the surface low still hovering along the Gulf. The LP will buzz through SE GA to the Atlantic in a few hours and likely take the tract closest to the Southernmost one. The geography of Metro Charlotte is varied and will play and effect on the precipitation here. The transition line will be somewhere near our south of Chester & Great Falls but north of Columbia and Florence in SC 2 Link to comment Share on other sites More sharing options...
Snow dog Posted Friday at 02:55 PM Share Posted Friday at 02:55 PM To my untrained eye on radar, looking more like the heaviest precip will stay to our south in the upstate.. 2 Link to comment Share on other sites More sharing options...

Take a look at the radar for western NC, the HRRR sniffed out the virga storm first for this region. 1 Link to comment Share on other sites More sharing options...
weatherfide Posted Friday at 02:56 PM Share Posted Friday at 02:56 PM FV3, Euro, and to a lesser extent HRRR did well with this one. NAM is trash and I see why they want to eliminate it. 1 Link to comment Share on other sites More sharing options...

burgertime Posted Friday at 03:01 PM Share Posted Friday at 03:01 PM Correct me if I'm wrong but it looks like on some of the short-range modes the storms in the gulf is helping rob some moisture upstream. Keep an eye on that at is can does have an impact. I'm a little less worried about ZR with this one for NC as much as the issue now with radars showing this kind of patch flow on the short range models. Good luck and I hope it overperforms! 4 Link to comment Share on other sites More sharing options...

Yes, there is a pretty strong line of thunderstorms that have developed off shore. Don't know if it is enought to impact our storm at this point. Will just have to watch it.

Yea you can really see those storms line up vertically which IRRC (I'm a bit rusty these days) is what does the robbing. If you see the storms in a more horizontal alignment that enhances. So keep an eye on the live radar for that. *EDITED- Ignore this as I had it mixed up. Thus why you should always listen to the professionals! 1 Link to comment Share on other sites More sharing options...

The jet dynamics are becoming more unfavorable with time, resulting in weakening frontogenesis near and above 700mb, which had been tapping into the dendritic growth zone earlier this morning. The bulk of our moisture with this higher up forcing came from the Pacific. Low level winds out of the E or SE are also bringing in drier air out of the weakening surface high. 3 Link to comment Share on other sites More sharing options...

From my experience, Gulf convection that is 'positively tilted' like that can actually enhance the moisture transport northeastward. What you don't want is the convection to race out ahead of the system and it take on more of a neutral or negative tilt orientation. Don't know if that makes sense or not. I'm tired. 9 Link to comment Share on other sites More sharing options...

purduewx80 Posted Friday at 03:16 PM Share Posted Friday at 03:16 PM The Carolinas are increasingly under the convergent quadrant of the upper jet, which diminishes the lift needed to maintain the band of heavier snow. Low level dynamics will kick in this afternoon but the DGZ is too high up for most areas to see the snow rates observed this morning. 9 Link to comment Share on other sites More sharing options...

Ah ok, yea I must of had it mixed it up. I could have sworn it was robbing when it was positively titled but now that you say that it's all coming back to me.

This was probably my fault as it's the end of the day here in the EU after a long week and I've been out of the game for awhile with winter storms in the SE.
