12/26-12/28 Potential Snow Threat

Ukie shows a 987 low on the benchmark .

Hence my YAWN at the 12z GFS ( which took its ugliest ensemble member and decided to advertise it as its midday operational solution ). I think the Global models will continue to go with a secondary off the VA coast and come Northeast .

Doest not mean a full blown snowstorm just that I 95 should be the battle lines.

The Euro will probably show something along these lines and than the GFS will correct over the next day .

The 12Z GFS ensembles also coming west leads me to believe the UKIE/Canadian are east because they are so strong on the Christmas wave.

Agree. These 2 european models want to decrease the upper level heights more than the gfs behind that wave because the x-mas wave is stronger on those models. This would allow a baroclinic zone to set up more to the south.

Steve D, JB and DT all just posted and said this run doest make any sense at all lol.

you must be a 3 stooges fan - anyways I think your post belonged in the banter thread snowman ! Ok so I don't just post banter looking at that rising NAO chart that is the reason the storm cuts - block is weakening

The models are much better than any of these guys at midrange synoptic forecasting. The first two guys I personally don't believe are even worth reading. If the GFS shows it, then it could probably happen. But it's still a good idea to lean towards the other midrange guidance.

It did in Christmas 1969 storm and "Snowicane" of February 25-26, 2010. Otherwise that's it.

December 19, 1995 and March 3, 2001 were sort of quasi-backlash like out here..

Its only west because the GFS flattens the confluence after the xmas storm . None of the other globals do that . think thats why you see this so far west .

The GFS loves to rush warm air thru the mid section and ohio valley , its as typical as running energy off the playing field too fast, it mayb doin in this suite .

Hang tight , I think you re introduce the confluence and its coming east .

Lets see if Euro agrees .

The answer is we are goin to need a more wrapped up 1st solution to create the confluence so the second system can transfer faster .

So pick 1 - do u want a white xmas - ( colder , less amped up solution ala Euro ) or a wetter warmer one on your xmas day which prob helps this system . probably cant have both .

Will some of you pls calm down . Its one run , this pattern is different than where we just where . Let it evolve

The models are just responding to the changes in the atmosphere , it takes time . This upcoming 20 day period should not look like the last 20 day period .

Its probably a continued painfully slow step down from where we were....I was semi-skeptical of this storm being the one but thought for sure the one after would be...turns out we may need to wait even beyond that for the +PNA to really kick in and give us a chance.

Yeh I hear ya , but sometime pos PNA wind up cold and dry , How many times do we see storms come out of the northern branch and slip underneath us .

I dont mind neg PNA neg NAO , big risk but big rewards pattern .If you set the confluence right , its just one right after another .

cold and dry is boring .
