griteater Posted January 27, 2014 Share Posted January 27, 2014 An excellent point eater. Alway nice for it to be displayed on the RGEM model today. Hopefully a push in the right direction. Would this lends towards any lee side development ? It looks like there is a weak inverted trough running up through the Savannah River Valley. I have noticed in the past with arctic air spilling over the mtns that the frontogenesis gets enhanced in NW SC into the foothills and southern piedmont of NC - i.e. tighter packing of the isotherms in the low levels aiding precip development Link to comment Share on other sites More sharing options...

wxcwman Posted January 27, 2014 Share Posted January 27, 2014 So I assume from reading that it's still an iffy situation, but in general the areas near lake Lanier should just see a couple snow showers from overrunning? I understand a lot can change but I don't understand why this ssystem is so surpressed? I've seen numerous gulf lows give a phlethra of precip inland. What's different this time?

dsaur Posted January 27, 2014 Share Posted January 27, 2014 It does not get any sharper than this. Hell this reminds me of lake effect snow bands where there could be 2 feet in one spot and 5 miles down the road there is hardly anything at all. I'm not sure if I have ever seen such a sharp cutoff down here where precip is not associated with a frontal passage. This is why I said earlier it's going to be nerve racking to see where this actually ends up being. It's far too close for comfort so hopefully it trends northwest by 25 miles. I mean 25 miles isn't too much to ask for is it?: After you had your own personal snow band over you a few years ago that just snowed and snowed on you while the rest of us watched, I don't worry about you any more, lol. It's me you need to be worrying about. I live through 73, and saw how sharp the fall off was, and felt the crushing disappointment, lol. I think we might ought to offer counselling to those getting too worked up, because this can turn some minds to mush before it's over Tony Link to comment Share on other sites More sharing options...

I mean 25 miles isn't too much to ask for is it?: This is the times that I really hate, lol! I would love to post an accumulation map, but I just can't at the moment. There is just so much uncertainty with this system. I am watching the shortwave over New Mexico, the baja low, the diving northern stream, and just wondering how all these will interact. Models seem to have converged on the idea that the baja low will not a factor, so even without this, what happens east of the mountains? I really don't know. I just told dad that I would not be shocked if we get nothing or four inches in the foothills of NC. Neither would shock me at the moment...

RaleighWx Posted January 27, 2014 Share Posted January 27, 2014 You have two regions of "A" on there. Can you be more specific on that western "A" over the mountains? Sorry that should be a separate region. 1-2 for there. Link to comment Share on other sites More sharing options...
Vorticity Posted January 27, 2014 Share Posted January 27, 2014 FWIW, here's my post in the general forum concerning the storm: Based on the latest ensemble and operational model guidance (prior to the 1/27 12z run of the ECMWF), one could probably make a case that the February 6-7, 1980 and March 1-2, 1980 snowstorms had reasonably similar 500 mb patterns. Below are charts showing the composite 500 mb anomalies for those two storms and qpf/snowfall for select cities: Taking into consideration those 500 mb cases and the latest guidance, snowfall risks can probably be listed as follows: Trace or Less: Boston New York City Philadelphia Washington, DC 1" or Less: Atlantic City Birmingham Savannah 1"-3": Atlanta Charleston 2"-4" Charlotte Columbia Richmond Wilmington, NC 3"-6": Raleigh 6" or More: Norfolk Actual useful info, thanks so much for sharing.

packbacker Posted January 27, 2014 Share Posted January 27, 2014 Euro definitely further west with the 0.1" of precip, past CLT and GSO, not sure if any heavy stuff is coming west of 95 though Link to comment Share on other sites More sharing options...
Brick Tamland Posted January 27, 2014 Share Posted January 27, 2014 Got this from the other board. It's from Birmingham NWS, but I thought it applied to the situation as a whole, too. AT THE ONSET OF THE EVENT TUESDAY MORNING...WE`LL HAVE TO CLOSELYWATCH THE RADAR RETURNS THAT WILL BE SETTING UP TO OUR WEST ANDSOUTHWEST AS THE OVERRUNNING PRECIP BEGINS TO DEVELOP. MODELGUIDANCE USUALLY HAS A TOUGH TIME RESOLVING OVERRUNNING PRECIPSITUATIONS...AND WE`VE ALREADY WITNESSED THAT QUITE A FEW TIMES OVERTHE PAST SEVERAL MONTHS. WITH THIS IN MIND AND A WETTER LOOK TO THESUITE OF GUIDANCE...I`VE DECIDED TO INCREASE POPS FURTHER NORTHWARDTO INCLUDE CHANCE POPS AS FAR NORTH AS THE I-59 CORRIDOR TUESDAYAFTERNOON THROUGH EARLY WEDNESDAY MORNING AS A GOOD BUFFER ZONEBETWEEN THE HIGHEST QPF AMOUNTS TO THE SOUTH AND THE POSSIBILITY OFPRECIP MOVING A BIT FARTHER NORTH THAN GUIDANCE IS INDICATING.

rduwx Posted January 27, 2014 Share Posted January 27, 2014 Euro has close to .5 for the RDU. That appears to be the number for this area. Hopefully it happens. Link to comment Share on other sites More sharing options...

Lookout Posted January 27, 2014 Share Posted January 27, 2014 12z euro now has 0.10 over much of northern ga, with half inch amounts from macon to columbia to eastern nc. 0.75 to 1 inch just south of there and 1 inch plus on the coast of upper sc and nc. In some cases it's 30 or 40 miles or so further north. Link to comment Share on other sites More sharing options...
deltadog03 Posted January 27, 2014 Share Posted January 27, 2014 EURO DEF wetter for more, including inland. There is a bit of a tilt from NE to SW (better this run, so qpf stays around a bit longer) LOVE this trend..keep it up! 12z GFS *IMO* was a bogus run.

packbacker Posted January 27, 2014 Share Posted January 27, 2014 It gets 0.5" to RDU, on the east side of Wake County almost 0.7" and RDU is only about miles from 0.8" of precip, huge jump. But it's also only 20 miles from 0.3" of precip, this is going to be nerve racking tomorrow. Link to comment Share on other sites More sharing options...
WeatherNC Posted January 27, 2014 Share Posted January 27, 2014 between 36 and 42 hours it puts the hammer down from FAY to PGV, likely a foot. Edit: 10.2" Link to comment Share on other sites More sharing options...

My confidence of seeing 2 to 4 inches has increased dramatically with this run. It is a big relief to FINALLY see this shift. Hopefully it makes one more like that because if it does me and you would probably end up with 0.50 or better. Link to comment Share on other sites More sharing options...

beanskip Posted January 27, 2014 Share Posted January 27, 2014 Seriously, I go back to the Wright Weather days on these boards -- I remember the RaleighWx Gempack PBPs. I moved to a place with no winter weather to speak of, but have a shot. Can somebody give me a Gulf Coast QPF report from the Euro. Thanks.
