This would support the 6z GFS with near .5 liquid near the RDU airport. The .25 would be just west of Charlotte and Winston-Salem. If this verified I think most would be happy.  

Yeah especially if it overperforms and the rates get around 14:1 or so...compared to where we were just yesterday before the 18z GFS this is good.

Personally I think anything over .25" for RDU would be a decent storm with at least a few inches. Interesting also that the models have sped up the arrival of precip for NC so we are now looking at an event that could be largely over by Wednesday late morning. It will be interesting to see what the 12z models have to say. If I was around I-95 in NC I'd be feeling really good right about now, though. Guys like Stuart (ncstatemmy) always seem to cash in on storms like this.

No eastward shift on the new SREF, so at least that's something. 

 

Am I missing something? It looked to me like it took a lot of the sig. moisture and shifted it east.  I'm looking at accum precip maps though. I would be interested in seeing the plumes and it put moisture in TX when there was none on the 3z.

looks dryer to me. I bet flurries at best for anyone north of 85.

12z runs are going to be crucial for us west obviously. If they will at least hold serve and not lower or go further east from the 6z then I think we will start seeing them ramp back up this afternoon. Personally I think the 2 s/w in out west are causing issues, the one swirling around Arizona/New Mexico could be what is causing the models to phase one run then not phase the next.

Interestingly enough on closer inspection it did shift light precip further NW. Probably due to a few plumes really phasing that energy if I had to guess.

I was comparing the 12-hour precip fields with the previous run. Didn't see a huge difference and like you mentioned, a slight NW jog of the edge of the precip shield. Waiting to pull the files into BUFKIT now for specifics.

That's why you get paid to look at the weather and I get paid to make up imaginative commercials. Interestingly enough upon initialization NAM looks slower compared to 6z with northern energy and that southern energy is weaker. Robert may also be on to something with that secondary vort out in Arizona that other posters mentioned on WV loop.

Water Vapor tells truth. Main upper low Baja is sending vorts into break-off upper low in Arizona. Will expand precip Tues in South.

 

I noticed this earlier as well. There is a definate spin over az this morning..which is way north of where the main upper low is and I'm not sure if the models are showing it very well.  It could get sheared out or have little effect but when i saw it, I was intrigued as well

Already 12z is keeping it in tact longer compared to 6z. Def. need to start watching that. Also because of that the vort off of the Baja isn't as strong.

Robert is going all in on this being a much bigger deal for central NC it seems.  He says NO model is showing the correct setup.  Pretty bold.  I hope he's right.

I have seemed to be in the lucky spot the past few years, especially 12/26/2010.  Last Turesday worked out well.  Hopefully my luck won't run out.  Going to be tricky Tuesday into Wednesday work wise.  I work in Raleigh, so if the precip starts falling before rush hour, getting home is to be awful.  I am concerned that with the temperature falling as much tonight as projected, anything that falls is going to stick to the roads, even in the daytime.  A 1/19/2005 redux in the triangle is not out of the realm of possibility.  My wife is an audiologist in Greenville.  I told this morning I doubt she and I will be going to work on Wednesday.  Crazt that my office might have a dusting and my wife's office could be buried, with us in between!

Hahaha. Well I've been staring at stuff way too long this morning. 

 

We will see where the 12z stuff goes. Still waiting on the latest SREF in BUFKIT.

 

FYI, for you Sandhills folks, the 3z SREF had 1.33" of QPF for FAY which looked to be almost entirely snow. On the other hand, it printed out 1.45" of QPF for ILM, a very large portion of which was ZR. That would obviously be a huge problem.

Based on the RAP the upper level vorticity center over AZ is pretty inconsequential to the main southern stream energy. The main area dives SE while the area in AZ dampens out. Interesting to see what happens.

 

Yeah, that's the trend I'm noticing.  Also the polar energy has shifted 50 miles west over the past 6 hours

It kills off at 12 on the latest run of the NAM....still that energy around the Baja is weaker which is a trend I was seeing on the RAP the last couple of runs.

Seems like over the past few days the models have been up and down. A few runs would have precip further north and the next couple would bring it back south a bit. All I'm saying is that I wouldn't be surprised if we get one more slight trend north before the nowcast begins. Let's see what the NAM says here in a few.
