simply making comments like "trends are bad" is just a waste of people's time. It  takes people longer to find meaninfull posts and information. Besides that fact, one can just read the posts of those who actually take the time to explain things to find out if the trend is good or bad. Making really obvious statements which adds nothing to the discussion simply aren't necessary and it annoys people. So the one liners need to be cut back folks.

 

Looking at the Hi-Res NAM there are some good returns over you. Of course reality can be totally different but if we can get that western energy to dig like it did on the 12z it only spells good things of your back yard I would think.

i think the heavy precip rates as depicted by the nam/gfs will help our temp issue here. any slight changes in the timing of the changeover will have huge implications in regards to ice or snow accums.  will be fun to watch.

I'll give it to the SREF members. Really the first ensemble members to pick up more precip back NW and its been holding its ground good over the last 48 hours or so.  Even though some of the extreme phase solutions have backed down to a more realistic mean.

Do you have an estimate for the York County, SC area perhaps?

Anyone else worried about the H coming down keeping totals from moving West? The 6z GFS shows it well I think. Right now I see RDU about 0.5" or a little better. WRAL threw out an avg of 5 inches for the area I guess that would be 10:1.

Taken literally, for Pensacola/FWB, 12z NAM shows rain changing to sleet in the afternoon, after covering the ground, changes to freezing rain -- .25-.35 of accretion later it ends as 1-2 inches of snow. Ugly.

 

We do not have the infrastructure to deal with this kind of an ice event. Got to go back to Christmas Eve 1989 for an analog. I-10 was shut down from Mobile to Jacksonville due to ice in overpasses. Tallahassee had a nice dusting back then.

Really interesting to see the NAM pop a 2nd coastal off shore with the southern stream s/w finally moving out and interacting with the polar branch a little too late.

 

IF IF IF that southern stream s/w were about 6 hours faster, then the big dog idea could happen for everyone. As it is the polar s/w itself is pretty potent, but it is going to favor a further east precip shield.

Never said a thing about NC....and the trends ARE bad. I didn't know I needed to write a synopsis on why.

No you should give a reasoning as to WHY they are bad, no one knows what your "bad" is. For some a bad trend gives them MORE winter weather. Also last time I checked the difference between western GA, SC, and NC were DRASTICALLY different than the eastern portion of those states. Stop posting and start reading

Its dialed in for my location but use the map below the plumes and find your location. It should give you a good estimate.

Regarding the SC coast, the 12z NAM keeps that second slug of moisture JUST off the coast as opposed to the prior couple of runs.  If the Lowcountry wants to see some snow, getting moisture from that on land will be key as that warm air aloft should be MOSTLY scoured out by then.

Do you buy it how it's depicted on the latest run of the NAM though? You would think it would keep kicking east and get swept up quicker. Or am I just wishcasting that?

The 850 line has moved offshore for part of the storm this run (first time since Saturday's models I believe), so odds of significant snow in CHS--especially away from the immediate coast--look to be increasing if the NAM is right. Mind you, there will still be a lot of ice too. It's going to be real nasty, and folks here aren't prepared.

12z RGEM has some nice trends through hour 18, northern stream s/w more southwest and digging more compared to prior runs and southern stream a little quicker.

 

Its also catching the initial WAA precip I was worried about over N AL, N GA and even SERN TN...the signal is there on the NAM too but its very weak, I would not be surprised if there is a narrow band of snow breaking out as early as 8-9am for places like RMG, CHA, BHM and maybe ATL although believe it or not I could see them shafted between that WAA and then the main slug

The RGEM just appears to have it furthest north run yet with precip over the Gulf states, given how insanely good its been this winter (only model that has done better than the GFS IMO) thats interesting.

 

 

With these northern trends, temps are going to become a big problem for those in the southern parts of these states and maybe even further north. This is going to become a nasty storm for many...

I was just about to post that. It's a good bit wetter than any prior run, especially on the north side.

Indeed.. again, just as with the NAM, the mean trough kicked back SW with the height field rising over the east and moving the precip axis further north.  More interaction with the Baja energy.

Quick SREF notes... totals a little higher in many spots. CLT and GSO saw a small increase. CLT now 0.26" and GSO also 0.26"

 

Fayetteville 0.94" all snow. 

 

Wilmington 0.82" .....mostly sleet or ZR... hopefully sleet.
