Buddy1987 Posted January 24, 2014 Share Posted January 24, 2014 6Z looks different with the vort at 78hr down in CA and even has some moisture showing up at the surface. We'll see where it goes. Link to comment Share on other sites More sharing options...
Buddy1987 Posted January 24, 2014 Share Posted January 24, 2014 Hr 93 has the vort down in baja hanging back more this run albeit weaker than hr 99 image. Precip starting to develop in LA. Link to comment Share on other sites More sharing options...
Buddy1987 Posted January 24, 2014 Share Posted January 24, 2014 Hr 105 has a new area of precip blossoming over southwest TX that wasnt there on the 0Z. Still hanging the vort back even at 105. Link to comment Share on other sites More sharing options...
Buddy1987 Posted January 24, 2014 Share Posted January 24, 2014 Hr 111 the 6Z GFS is a lot different in respect to the southern vort as there is significant precip heading to southern LA and gulf of mexico. Vort still hanging back this run might be good if it can keep it up and not shoot out in front of the energy dropping down. Link to comment Share on other sites More sharing options...

Buddy1987 Posted January 24, 2014 Share Posted January 24, 2014 Ill have someone digest and look at this run with a little more knowledge but that was a completely different look on the GFS with the main southern stream being more dominant imho. It had a significant outbreak of precip that formed in southwest TX and move throughout the gulf to the florida panhandle and brush the GA and SC coasts. No digging with that northern stream is what is killing this thing. If we can swing that moisture north/northwest that was a good looking run in regard to precip now we just need the northern stream to do its part.

Poimen Posted January 24, 2014 Share Posted January 24, 2014 The 6Z GFS finally gets there...about 24 hours later than the EC/GGEM. The bottom line is that the signal for a SE snow storm is high...the details of when, where and how much are far from being resolved. I've heard the 0Z EC Ensemble mean was similar to the op.

Poimen, what do we need to happen in order to get this thing up the coast. Block in southeast Canada to move more north and east? Have the northern stream start to dig sooner? How much sooner would you like to see it dig? Its so close but yet so far that 6Z GFS with the moisture in the gulf was impressive! Link to comment Share on other sites More sharing options...

FallsLake Posted January 24, 2014 Share Posted January 24, 2014 Guys don't let the wobble of the euro upset you. The 6z GFS this morning continues the westward trend and that's what we need to be looking for. I think the euro will start trending back westward with the next few runs; now there will definitely be some back steps. What we're looking for is overall setup. Really it's going to be the last two or three days until the real track is determined (remember x-mas storm). From RAH: MUCH UNCERTAINTY REMAINS FOR THE TUESDAY NIGHT-WEDNESDAY PERIOD.ECMWF STILL SUGGEST A DECENT S/W DIVING SEWD OUT OF THE FRONT RANGEOF THE COLORADO ROCKIES TUESDAY...MERGING WITH ANOTHER SYSTEMCROSSING THE NORTHERN GULF...WHICH THEN LIFTS NEWD ALONG THE SE U.S.COAST LATE TUESDAY NIGHT INTO WEDNESDAY. THIS MORE WESTWARD TRACKWOULD AID TO DEVELOP SFC CYCLOGENESIS ALONG A STALLED SFC FRONTOFFSHORE. IF THIS WERE TO OCCUR...THIS LOW PRESSURE SYSTEM COULDSWING MOISTURE WESTWARD INTO CENTRAL NC. TEMPS WILL BE COLD ENOUGHTO SUPPORT FROZEN PRECIPITATION OVER OUR REGION. GFS IS MUCH WEAKERAND MORE PROGRESSIVE WITH THE S/W CROSSING THE SOUTHERN PLAINS...NOTSUGGESTING A MERGER OR STRENGTHENING TAKING PLACE UNTIL THE SYSTEMIS OFFSHORE OF GA/SC AND MOVING STEADILY EASTWARD. CONSIDERING THEBAROCLINICITY THAT WILL LIKELY LIE OVER THE GULF STREAM AS WELL ASOVER THE NORTHERN GULF COAST...SOME CREDENCE NEEDS TO BE GIVEN TOTHE ECMWF. SINCE THIS SCENARIO IS STILL 5-6 DAYS OUT...A LOT CANCHANGE IN MODEL GUIDANCE. THUS WILL MAINTAIN A SLIGHT CHANCE FORSNOW TUESDAY NIGHT INTO WEDNESDAY ACROSS CENTRAL NC.

NCSNOW Posted January 24, 2014 Share Posted January 24, 2014 Riding the euro ensembles. Think the threat of a pattern very conducive to bringing a winter storm to large parts of the SE Tues/Wed has more than enough consensus from the models and their ensembles to qualify as legit now. The weekend model cycles will be very interesting to watch the trends. I'm biased but hugging the euro ensembles is the best medicine. As we get more toward Sunday time frame we should hopefully be able to use more blend of other suites, espeacilly their ensembles in order to get a firmer idea of our back yard details.

NavarreDon Posted January 24, 2014 Share Posted January 24, 2014 GSP's overnight disco: THE MODELS DIVERGE SIGFNTLY WRT TO HOW SHARP THE S/W WILL BE BYWED NIGHT. THE ENS MEMBERS OF THE GFS SHOW THE BEST SPREAD TO THEEAST OF THE MEAN TROF INDICATING A QUICKER AND LESS AMPLIFIED WAVETHAN PREVIOUS RUN...WHICH AGREES WELL WITH THE LATEST OP GFS. THISSCENARIO ENABLES A SUPRESSING CA SFC HIGH INTO THE AREA WITH LITTLEIF ANY CYCLOGENESIS ALONG THE COASTAL BAROCLINIC ZONE. THE LATESTECMWF HAS COME IN WEAKER THAN IT/S PREVIOUS RUN WITH THE UPPERENERGY...YET STILL DOES FORM A SFC CYCLONE OFF THE ATL COAST BY 12ZWED...WHICH IS SIMILAR IN PLACEMENT TO THE 00Z CMC SOLN. ALL MODELSDO DEVELOP AN INVERTED TROF AXIS OVER THE AREA TUE NIGHT INTO WEDWHICH COULD SUPPORT ENOUGH INFLUX OF LLVL MOISTURE TO PERHAPSGENERATE -SNSH ACROSS THE ERN MOST ZONES. THIS IS NOT A HIGHCONFIDENCE SCENARIO THO CONSIDERING THE MODEL DISPREPANCIES AND RUNTO RUN TRENDS. THUS...POPS HAVE BEEN LOWERED WEST AND SLIGHT CHANCESNOW POPS REMAIN GENERALLY EAST OF I85 TUE NIGHT.IT WILL BE ANOTHER WELL BELOW NORMAL COLD DAY WED AS THE ARCTIC HIGHSETTLES OVER THE REGION AND MAX TEMPS SHOULD BE HELD ABOUT 20DEGREES BELOW NORMAL IN GOOD INSOLATION. THE LLVL THERMAL TROFMODIFIES BETTER ON THU...HOWEVER MAXES WILL LIKELY STILL BE 10-15DEGREES BELOW NORMAL.

burgertime Posted January 24, 2014 Share Posted January 24, 2014 As usual the models are going to go back and forth with this. Everything depends on how far the energy digs SW of here and how far west that trough gets. Energy will not even be properly sampled until probably Sunday night so even if the trough to the west is nice and sharp which piece of energy does the model hone in on? This is going to be one of those schizophrenic next couple of days on this board. Don't get to Lookout's cliff until about Monday folks. Link to comment Share on other sites More sharing options...
timnc910 Posted January 24, 2014 Share Posted January 24, 2014 I'm feeling confident about this one.. the euro and its ensemble have been consistent yesterday and continue to show a storm next Tuesday. Euro now has back up from the canadian and the gfs ensembles are starting to come around also... the local mets in the east are already talking about this system and that not like them until about 3 days out from the event but already a 40% chance Tuesday and Wednesday for wintry precip.

Brick Tamland Posted January 24, 2014 Share Posted January 24, 2014 The one thing I was worried about was it going too far east. It does look like there will be snow, but just a matter of how much and where. I would love to see it one back west some and there is plenty of time.

strongwxnc Posted January 24, 2014 Share Posted January 24, 2014 Two great points to keep in mind both which will not be determined, as you stated, until the end of the weekend. Either way, tracking will be fun. As usual the models are going to go back and forth with this. Everything depends on how far the energy digs SW of here and how far west that trough gets.

Either way, tracking will be fun. Agreed. I think we'd all like the entire southeast to get crushed, but this is like hunting a 14-point buck as deer season winds down. Everyone has to dust off their tracking skills and watch for signs. And someone is going to go home with a trophy buck. Link to comment Share on other sites More sharing options...
packbacker Posted January 24, 2014 Share Posted January 24, 2014 #1 CIP's analog for day 5 on the GFS is 12/31/2001, a couple days later wasn't to bad of a winter storm in the SE. Link to comment Share on other sites More sharing options...
griteater Posted January 24, 2014 Share Posted January 24, 2014 The 06z GFS is actually completely different than the 00z in terms of the key vort maxes. The vort max/shortwave we've been watching all along tracks farther north on the 06z run through Missouri, the KY/TN border, and into northern VA. Then there are 2 pieces of energy, one off the Pacific Jet, and one off the Arctic Jet, that drop into the eastern trough and lead to precip in coastal areas, but later, on Thurs night. The Euro is slower and weaker with that trailing shortwave complex compared to the 06z GFS. Nothing has changed with the potential here...vort max/shortwave mess will have to get sorted out in time.

metalicwx366 Posted January 24, 2014 Share Posted January 24, 2014 I'm actually excited for this threat. We might actually see some accumulating snow for the first time in this area since 1989. TWC has a 60% chance of wintry mix and wunderground says wintry mix with accumulations of snow and ice up to 1 inch. Then snow showers the next morning. NWS says rain Tuesday night. We should let GaWx start all the threads. He started the one in March last year and we all got flurries and snow showers. Link to comment Share on other sites More sharing options...
griteater Posted January 24, 2014 Share Posted January 24, 2014 For the 20 GFS Ensemble members on the 06z GFS, I have a rough count of 4 that produce precip inland, with 8 confining precip to coastal areas, and 12 members mostly dry...this is for NC/SC. There are varying timeframes in which the precip occurs, but it's over the course of next week Link to comment Share on other sites More sharing options...

As long as the Ens members stay at least the same or keep ticking up we are in good shape even if the Op keeps missing wide right at this range. 12z GEFS - 3 members had precip back to I-95 (at least 0.25" or greater) 18z GEFS - same as 12z 0z GEFS - 5 members had precip back to I-95 (at least 0.25" or greater) 6z GEFS - 5 members had precip back to I-95 (at least 0.25" or greater), Link to comment Share on other sites More sharing options...
