Stormsfury Posted January 27, 2014 Share Posted January 27, 2014 Ice Storm warning now in effect for Charleston I didn't see any updates from the NWS just yet, or upgrades. I'm sure a lot of discussion going on behind the scenes WRT's to what kind of warnings to issue, given the predominant p-type issues. EDIT: NVM, I see the headlining in the ZFP products Link to comment Share on other sites More sharing options...
superjames1992 Posted January 27, 2014 Share Posted January 27, 2014 The SREF plumes from 15z give GSO a mean of 3" of snow, but there's a lot of spread. There's a bunch of members with 4-7" and a lot of members with 0-1"... not a lot of middle ground. CLT is a little more clustered with a mean of 3.33" There's a couple ridiculous members and a few duds, but every other ensemble member shows 1-5". It's going to be interesting in the western Piedmont. Link to comment Share on other sites More sharing options...
GaWx Posted January 27, 2014 Share Posted January 27, 2014 it's a good bit colder and actually looks to put a little more snow down in SC. hour 39-42, 850-925mb temperatures crash with still decent precip rates ongoing. still appears a lot of front end ZR/IP along the SC coast. SF, Do you think the 850's are too warm on the consensus due to the fresh supply of Arctic air not being modeled cold enough? Now it is in the +3 to +5 range, which is very much within the ZR threat zone, before changing to IP and then S. Link to comment Share on other sites More sharing options...

Well, the transition line has a shallow layer of arctic air, there's certainly more chances of dangerous ZR accumulations occurring before the warm nose cools, unfortunately.

I'm sure a lot of discussion going on behind the scenes WRT's to what kind of warnings to issue, given the predominant p-type issues. Charleston County in the Ice Storm warning...Berkeley and Dorchester in the WSW as they add in the 2-4" of snow. Probably going to be misleading for a lot of people as some parts of those counties dip farther south than Charleston, but those are the facts of county-by-county warnings.

WX262 Posted January 27, 2014 Share Posted January 27, 2014 Meh... not in my book Agree- That appears to be an older map that Holcomb posted from 11Alive. He does not have the Winter Storm Warning areas highlighted on his forecast Map for Georgia. So his forecast totals will most likely be updated Link to comment Share on other sites More sharing options...

I'm sure a lot of discussion going on behind the scenes WRT's to what kind of warnings to issue, given the predominant p-type issues. It is in the zones. Ice storm warning for the entire coastal corridor CHS to SAV. Ice accum. of 0.35-0.6 CHS and 0.25-0.50" SAV. For SAV, that would be the worst since 1/1922 if it verifies!! They're going colder than the model consensus of 32-33 in SAV and are going with upper 20's with ZR Tue night followed by a change to snow late Tue night.. Going to be a very interesting Tuesday into Wed.! Link to comment Share on other sites More sharing options...

I had edited my original post, and saw it in the ZFP. yeah, you're right, because based on the ZFP itself, over .50" of ice accretions expected before the changeover. Definitely the potential to be the worst icestorm since Feb 1979. Link to comment Share on other sites More sharing options...

packbacker Posted January 27, 2014 Share Posted January 27, 2014 Doesn't seem like much of a change from WRAL. They shifted it about 30 miles west. We are going to miss out on 6" by about 20 or so miles, assuming there isn't a big bust. Link to comment Share on other sites More sharing options...
FLweather Posted January 27, 2014 Share Posted January 27, 2014 Looking at the latest RAP at 18 hours that energy is very N/S oriented and almost dipping into Arizona. 18z GFS had it more E/W oriented and as soon as it got close to AZ it jumped east. We need to play close attention to what the RAP does with that energy. If it can dig a little more I suspect you may get some interaction with that southern vort. At the very least it should help with more precip as it moves further east...again if it digs further than the NAM and keeps a more neutral orientation. Yeah I just don't see how the models continue to maintain that baja low and even show it closed at times. Just no way really its being ripped to pieces by the N/S and absorb into the NS aswell. In fact does look like its tracking east atm so it may just get fully absorbed. Which should sharpen the N/S trough and would be a good thing.

beanskip Posted January 27, 2014 Share Posted January 27, 2014 Don't know if it's related, but southern stream energy a good 100-200 miles east at 18h. Big time change out to 30 on the 18z compared to 12z. This is a good bit wetter for ENC and parts of GA/SC. Link to comment Share on other sites More sharing options...
burgertime Posted January 27, 2014 Author Share Posted January 27, 2014 Wow -- nice little east shift with southern stream energy on 18z GFS vs. 12z run -- too late to matter? I don't think it matters much but if the GFS is catching on to something and it can speed up a little more it will. Either way nice improvement on the GFS. I wouldn't be surprised if MBY didn't finish with like .30 or so on that run. Link to comment Share on other sites More sharing options...
