I like using the SREF mean just for precip amount trends, not necessarily for the actual amount it puts out. Is the amount increasing or not - that's what I like if for
HRRR, 3K NAM, RGEM etc…When KFFC talks about hi-res guidance, which models are they talking about?
Models with a 3km grid resolution (3 kilometers between gridpoints). More precise simulations.. more costly, so they only go out to 48 or 60 hours into the future. Examples; HRRR, nam3km, HRWWhen KFFC talks about hi-res guidance, which models are they talking about?
He’s not going to go all out to begin with, no meteorologist would, but yes this feels too light.
Thanks. Those are ones I'm familiar with but it's been so long since I've sweated a winter storm. And I hear a lot of ridicule for the HRRR, but I guess that is mainly for output at the end of its rangeHRRR, 3K NAM, RGEM etc…
Chasing too!! Girls trip to Young Harris, Ga!! Towns County!! GA/NC border.. Leaving Thursday nite. Brasstown Valley Resort!! Perfect place to chase!I’ll be live from the mountains in Blue Ridge Georgia for this one. Not feeling too hot about our area down here, so going to chase it with the family. Hope everyone scores big!
I looked on the website and couldn't find this grid. Could you share where this is located please?FFC upped their grid amounts for snow. Almost doubled here. Old total was 2.1 or so, new is over 4.

I don't necessarily disagree BUT, as with most tv Mets, they will start low and adjust upward as needed. It's much easier to go up than back off. Either way, it's going to be a significant storm and one that hasn't been around for many years.B Rad, doing B Rad things

Was thinking about this earlier. I do think they probably go winter storm watch down to I-20 or thereabouts and then just a Winter Weather Advisory south of there probably down to Macon or so to account for risksSince we will be within 48 hours tomorrow I would expect FFC to issue a winter storm watch for a good chunk of North GA. Anyone have any thoughts on how far south the inital watch might be issued? My guess based on the data ive seen so far would be around or maybe a row of counties just north of I-20. Keep in mind, high enough risk of significant IP/ZR would be enough to warrant one for places further south.
Prediction: WSW for north of I-20 including Fulton. WWA advisories for the south metro and SPS down to Columbus and Macon.Since we will be within 48 hours tomorrow I would expect FFC to issue a winter storm watch for a good chunk of North GA.

Probably winter storm watch by 12 tomorrow for I-20 N as mentioned. I expect an upgrade for Forsyth North come storm time initially and the next row below if criteria are met and WWA's for I-20 north. I could see the first row of counties below Forsyth, Hall, and Cherokee upgraded too when the watch expires.Since we will be within 48 hours tomorrow I would expect FFC to issue a winter storm watch for a good chunk of North GA.

What we really do not want is an east to west line the goes from just offshore of the Fla panhandle back to south of New Orleans LA. That would really cut amounts.They can help or hurt. If the line races out ahead, that's no good. A slow moving line in step with the system can actually help with moisture transport.
Yes, needs to look like a squall line not a frontal boundary lineWhat we really do not want is an east to west line the goes from just offshore of the Fla panhandle back to south of New Orleans LA. That would really cut amounts.
My original spot has been Northern Gwinnett and there has not been a good hit when there was a Winter Storm Warning issued the night before since the 2011 storm. Every hit, even marginal, has just been an advisory if my memory serves me right.Probably winter storm watch by 12 tomorrow for I-20 N as mentioned.

I feel like the last event where folks were super aggressive was 2014. We had foot totals being thrown out five days aheadI don't necessarily disagree BUT, as with most tv Mets, they will start low and adjust upward as needed. It's much easier to go up than back off.

One county makes a huge difference but I think FFC's bust of the past two decades was still 2017, that one was a shock to most, and 2014 may have been a Forsyth N storm. The small 2020 hit also snuck up on us.My original spot has been Northern Gwinnett and there has not been a good hit when there was a Winter Storm Warning issued the night before since the 2011 storm.

I wanna add to this, it’s not impossible to get a Carolina split in this type of track. Something models sometimes “miss” 24hrs before the event.I think brads forecast is great at this lead time. If you blend everything that’s about it. There’s a few signs pointing to lower QPF east of the apps, possibly due to enhanced connecting robbing to our south and lots of initial dry air in the low levels. Especially if we get a flatter solution.
It wasn't just tv broadcasters. NWS GSP upped my totals from 4-6 to 8-12 inches like 8 hours before the event started, and it was already clear as day we were toast. I got about an inch of slop.I feel like the last event where folks were super aggressive was 2014. We had foot totals being thrown out five days ahead
