BowMeHunter Posted January 28, 2011 Share Posted January 28, 2011 Thankfully I won't be around for any 12z Euro disappointment and when I get home for the 0z's I'm pretty sure I'll be hopped up on meds so I'll be feeling good no matter the outcome of models. Have fun tracking tomorrow, y'all. Link to comment Share on other sites More sharing options...

dilly84 Posted January 28, 2011 Share Posted January 28, 2011 Basically still have a wide variety of solutions, but with the trends its safe to say, odds are this thing will be NW. GFS looks good for us OV people, other runs, not so much. I suspect the gfs will trend towards the euro, and the euro will be weaker than what it showed tonight.. see ya at 12z people.

Justin Posted January 28, 2011 Share Posted January 28, 2011 This one is looking like she could be quite a winner for a lot of folks... but could be a zone, from the looks of things, of major icing. Lots of time still to go watching this one. I'm very interested in watching what the cold air over Hudson bay does and how that plays out with the jet and potential phasing issues. I can't help but remember the trend most of this Winter has been to send the decent storms hard left (the first big one up in MN/WI) where a lot of us got rain, or far to the South and then up the East Coast. I figured the MW would be due for a major storm towards the end of January before another period of pretty cold weather and I was a day or two off perhaps. But needless to say this thing is looking good for someone in the Eastern half of the nation to get nailed again. I don't buy into the huge QPF numbers quite yet...more times than not in snow situations those #'s don't pan out. Cut them by 1/3 or 1/4 and that would be a more realistic solution. Seen models over estimate QPF to many times rather than underestimate. So we'll see over the weekend with new data coming in every day. Going to be a fun weekend. Everyone keep the snowblowers, shovels, and ice scrapers handy...heck some parts of the Southern Midwest may need hip waders if this thing tracks far enough North and produces a heavy rain over areas with a decent snow pack. I'm cautiously optimistic on this one. Link to comment Share on other sites More sharing options...
Justin Posted January 28, 2011 Share Posted January 28, 2011 BTW I will try and post again tomorrow evening after I've had a chance to digest all the data and collect my thoughts and feelings on this. Try and see everyone around say 10pm or there abouts. I'll keep logged into the thread so I don't lose my place. I can just see this thing going in so many different directions and making a lot of us very happy or very upset. Not a good feel yet, but again cautiously optimistic.

Luckily Im a weather enthusiast no matter the situation. If I get a foot of windblown snow or a 990mb low sitting over my head with 50 degree temps and dry slots, I enjoy it one way or the other. In this hobby you cant be narrow-minded (always wanting a major snow or severe weather outbreak) It will drive you nuts and thats why there are quite a few angry and unpleasent ppl/post on this board. Thats why Im not a huge poster, Im usually out enjoying the weather rather than complaining about it. But thats my opinion...BTW I hope this one can spread the wealth! Your thoughts are always welcome and much appreciated Justin. Link to comment Share on other sites More sharing options...

TheWeatherPimp Posted January 28, 2011 Share Posted January 28, 2011 IWX: LONG TERM SUN THROUGH THURSDAY VERY ACTIVE NORTHERN PAC FLOW WILL OFFER SEVERAL CHANCES OF SNOW INTO THE GREAT LAKES AS BLOCKED FLOW OVER THE NORTHERN ATLANTIC BREAKS DOWN. EASTERN PAC RIDGING TYPICAL OF A STRONG LA NINA INFLUENCE WILL SUPPORT A TRANSITION TO WESTERN CONUS TROUGHING AND HIGHLY AMPLIFIED FLOW...WITH A VERY STRONG SYSTEM EXPECTED TO EJECT OUT OF THE SW CONUS INTO THE MID CONUS EARLY NEXT WEEK...WITH THE POTENTIAL FOR A WINTER STORM IN THE REGION. ANALOGS TO THE FORECAST HEIGHT PATTERN SUPPORT A POTENT NEGATIVELY TILTED UPPER HEIGHT PATTERN VERY SUPPORTIVE TO DEEP CYCLOGENESIS. FORECAST MODELS ARE HAVING MAJOR DIFFICULTY PER UPPER JET DETAILS WITH HUGE RUN-RUN DIFFERENCES PER SFC SYSTEM TRACK/TIMING/AND INTENSITY...WITH THE GEM/DGEX BEING THE MOST CONSISTENT IN THIS DEPARTMENT. LATER PORTION OF THE FORECAST PERIOD WILL BE HIGHLY DICTATED BY THE DEGREE OF NORTHERN STREAM PHASING...WITH CAA INTENSITY BEING THE MOST AFFECTED. IF A LONG WAVE PHASED TROUGH DOES MATERIALIZE...MUCH COLDER CONDITIONS WOULD BE EXPECTED INTO THE REGION...A SOLUTION THAT IS FAVORED BY THE GEM AND GFS. DIFFICULTY ALSO ARISES WHEN TRYING TO DETERMINE THE FLOW TENDENCY BY LATE NEXT WEEK WITH MOST MODELS OPTING FOR A TREND TO HIGHLY PROGRESSIVE FLOW...SHIFTING THE BULK OF THE ARCTIC AIR EAST. THE MEAN GEFS IS BIASED WEST WITH UPPER TROUGH PLACEMENT IN THIS PERIOD...WITH COLDER AIR PROGGED OVER THE REGION. PREFERENCE IS TOWARD A MORE PROGRESSIVE FLOW TENDENCY GIVEN THE NORM THIS SEASON. THIS WOULD SUPPORT ONLY A GLANCING INFLUENCE OF THE ARCTIC AIRMASS. PREFERENCE WAS TO TOWARD A HIGHLY AMPLIFIED HEIGHT PATTERN MID WEEK WHICH IS CLOSE TO A GEM/GFS/DGEX BLEND. DID ADJUST TEMPS AND WEATHER FOR THESE CONCERNS. SUN-TUE...NOT MUCH CHANGE IN THIS PERIOD AS GENERALLY WEAK FAST MOVING IMPULSES ARE PROGGED GIVEN WITH NEAR NEUTRAL TEMP ADV. HAVE RETAINED LOW CHANCE POPS/WX. TUE NIGHT-THUR....ADJUSTED THE GRIDS TO REFLECT A HIGHLY AMPLIFIED HEIGHT PATTERN WITH A DEEP SFC CYCLONE EXPECTED IN THE MID CONUS. THIS SUPPORTS ADDITION/INCREASE IN POP NUMBERS...ESPECIALLY IN THE TUE NIGHT PERIOD WHERE MODEL SIGNALS OVERLAP GREATEST /EVEN THOUGH SYSTEM TIMING IS HIGHLY VARIABLE AMONG INDIVIDUAL MEMBERS/. HAVE ADJUSTED TEMPS TO REFLECT A WEAK WARMING TREND TUE-WED...WITH COOLER THERMAL FIELDS EXPECTED BY THUR. AS STATED ABOVE...GIVEN CONCERNS FOR A PROGRESSIVE TENDENCY TO THE FLOW...HAVE OPTED FOR CONSERVATIVE TEMP NUMBERS ATTM. THE POTENTIAL IS THERE FOR SIG SNOW ACCUMS...AND IF JET INTENSITY IS MUCH MORE ROBUST AND CYCLONICALLY CURVED /WHICH IS ENTIRELY PLAUSIBLE/ THE REGION WOULD SEE MIXED PRECIP WITH A POTENTIAL CHANGE OVER TO ALL RAIN. THE BIGGEST QUESTION WILL BE THE INTENSITY OF AN ADVECTING SFC RIDGE OUT OF THE NORTHERN PLAINS...AS THIS SYSTEM WILL HIGHLY IMPACT THE LOCATION OF THE ASSOCIATED LL BAROCLINIC ZONE FAVORED FOR CYCLOGENESIS AS WELL AS MID AND UPPER FLOW DETAILS. WILL CONTINUE TO MONITOR FOR TRENDS. Link to comment Share on other sites More sharing options...
weatherguru Posted January 28, 2011 Share Posted January 28, 2011 06 gfs took a step towards the euro Might end up being a Indy to Detroit storm track with decent WAA ahead of system and deformation band and Lake ehancement across N.IL/S.WI. 18-24hr period of snow. Altantic/Gulf Moisture involved equals 99 blizzard. Watch this go on a strong neg tilt. WGN 9 Chicago said 2-4 on Tuesday and potentially more on Wednesday additional snow. Bears watching.

A-L-E-K Posted January 28, 2011 Share Posted January 28, 2011 did you notice this trend on tonights modeling.......jseemed to me the trend of leaving a lot of energy lagging behind....could be wrong as i didnt look all that closely noticed it as well, i think we see it continue as well as some future shifts southeast.

A-L-E-K Posted January 28, 2011 Share Posted January 28, 2011 Just getting caught up. As for those surprised by wild changes needs to realize just how the minor differences with the evolution of the Pac players early in the runs translated to major changes down the road. In other words, things could shift back south in a heartbeat. 6z NAM looka like it would be south of 0z, with the northern piece further east. We also saw just how far NW it can go even without a full ejection, which should give you an idea of tha massive range in possible tracks right now. EDIT: now i have to wait for all you weenie who stayed up all night to chat with me Link to comment Share on other sites More sharing options...
TheWeatherPimp Posted January 28, 2011 Share Posted January 28, 2011 FWIW, a lot of NWS offices seem to be riding the DGEX due to it's consistency and 06z run is about identical to it's previous runs and similar to the 00z GFS. Also FWIW, the DGEX has another interesting system by Friday and Saturday. Link to comment Share on other sites More sharing options...

Stevo6899 Posted January 28, 2011 Share Posted January 28, 2011 5 hours of sleep and I barely made it into work. Morning guys. Grr THE LOW WILL MOVE ACROSS THE OHIO VALLEY AND OFF THE MID ATLANTIC COAST BY WEDNESDAY ACCORDING TO THE GFS...WHICH HAS TRENDED THE NORTHERN EDGE OF THE SNOW FURTHER NORTH OVER THE LAST 24 HOURS...BRINGING IT TO OUR FAR SOUTHEAST FORECAST AREA. THE EURO HAS HAD A FEW RUNS WHERE THE LONGWAVE PATTERN IS AMPLIFIED ENOUGH TO ALLOW THE LOW TO MOVE MUCH FURTHER NORTH AND BRING HEAVIER SNOW WELL INTO LOWER MICHIGAN. HAVE DISCOUNTED THIS MORE AMPLIFIED SOLUTION BUT WILL DEFINITELY HAVE TO WATCH FUTURE TRENDS TO SEE IF LOWER MICHIGAN WILL FINALLY HAVE A SIGNIFICANT SYNOPTIC SNOW EVENT. DTX MODELS LOOK MORE IN LINE WITH A PATTERN SHIFT OCCURRING TOWARDS THE BEGINNING OF NEXT WEEK. POLAR VORTEX OVER HUDSON BAY LOOKS TO LIFT FAR ENOUGH NORTHWARD TO PULL MICHIGAN OUT OF THE NORTHWEST FLOW/CLIPPER PATTERN WE HAVE BEEN STUCK IN MOST OF THE WINTER.SOUTHWEST FLOW THEN LOOKS TO DEVELOP IN ADVANCE OF DEEP UPPER TROUGHING THAT DIGS INTO THE U.S. SOUTHWEST...WITH SURFACE LOW PRESSURE POTENTIALLY TRACKING UP INTO THE SOUTHERN OHIO VALLEY TOWARDS MIDWEEK AS THE AMPLIFIED UPPER TROUGH PROGRESSES EASTWARD. THIS IS A CLASSIC WINTER STORM SET-UP FOR SOUTHEAST MICHIGAN Link to comment Share on other sites More sharing options...

We have a decent safety net, it would take a pretty special phase and a full ejection from the southwest to realize that potential. I don't see it happening. Possible sure, but it would be a once in a lifetime storm for someone. Link to comment Share on other sites More sharing options...

I don't see it happening. Possible sure, but it would be a once in a lifetime storm for someone. Yea it looks good. Just north of the heavy precip, but I think its good to not be in the sweet spot right now. Of course a little skeptical that it bombs too quick (assuming it phases which isn't even known yet) and falls apart as it heads into the colder drier air up here. One thing is for sure .5 of precip will do alot more up here than it will further south where 2 inch plus may fall. Always forget to remember ratios and they should be very good up here.

Too early for ratio and qpf talk. Lets stay focused on the trends out west and worry about that business later. Personally I will be surprised if models are as far west with the northern vort at 12z.

Chicago WX Posted January 28, 2011 Share Posted January 28, 2011 So how about that 6z GFS? Just an ordinary 8-10" hit of snow here with JLN, STL, S IL, etc getting buried. Regardless, nice to see some previously "amped" solutions jump back on board last night. Long ways to go still, but needless to say good things happened for a lot folks in this forum.

River Card Posted January 28, 2011 Share Posted January 28, 2011 Gotta really like the GFS right now and since the upgrade have been very impressed with it this winter. The ECMWF seems clueless to the the storms lower level mass fields while the GFS locks onto it and also with the deep punch of arctic air history would suggest this favors a more southern track. Sure seems like someone is gonna get a good storm out of this at this juncture. Kinda looks like a quick hit of arctic air with a more W to E spill rather than a slower moving N to S. Kinda like the last surge where the core misses the upper midwest and focuses more out east. Link to comment Share on other sites More sharing options...
