Late February 2013 Mid-Long Range Discussion

We pretend March 2001 didn't happen.  I saw the '93 reference, but the superstorm was a full 10 days later...

Our chance at a big storm may come at the tail end of this pattern also.  I know getting into mid March is really a long shot for most of us...but thats just how the timing looks to be working out.

He is a spin master and plays on the assumption that most poeple do not have the knowledge to know when he is feeding them BS. He is finally admitting at least that his mid atlantic forecast is in big trouble if something doesnt change.  No matter what his temp forecast will bust, and he needs a miracle to back door his way to a verification on snowfall.  But what he implies with those dates is misleading at best since 1969 did nothing for us, and the 2010 analogs showing up are mostly from late Feb and March, AFTER the snowy period for us...during the period where NY and New England cashed in.  Neither of those analogs is encouraging at all for the mid atlantic which is the area he admits he needs help and tries to imply the ensembles show it is coming.  The only analog popping up recently that has promise for our area is the March 1960, that was a 22" snowfall month at BWI.  Most of what JB says anymore is manipulative and spin with a sprinkling of truth to make it seem belieavable. 

well if bastardi is going to say the ensembles say "lookout" he should show via twitter exactly what the ensembles are showing, not just what he thinks they're saying. What a croc. He is misleading at best. He keeps showing the EC snowfall map to justfy his forecast, why not show the ensembles. I wont even go into his global warming babble. or psu wrestling talk!!

Has anyone seen the ECMWF ensembles? I know it's JB (take with a grain of salt), but I'm curious to see what he is getting at. Just a few mins ago he posted:

http://Weatherbell.com snow forecast has had New England and now plains verified. Mid atlantic left to fill in.ECMWF ensembles say lookout!

Of the 1200 possible candidates for D plus 8, D plus 11 in the super analog package, NINE are from great end game yrs of 2010,1969! Amazing

He's still relevant if people are writing essay posts about him, good or bad. Keep it up - he loves the attention.

I just put the 500 panels side by side of the last 4 runs of the gfs @ same point in time using 12z hr 150 as the starting point. I'm pretty intrigued with the setup. Big medicine ball spinning in se canada and a fairly decent vort coming around underneath. Verbatim it gets a bit squashed but the trend is certainly good. 12z puts us in a .1+ precip swath with all snow temps. Weak surface low pops in front of the vort and takes a decent track. It has trended wetter each subsequent run and the ul flow keeps getting better to allow more amplification.

 

Yea, the whole thing could go poof. We all know this. But I'm liking the consistency here. This is the kind of setup that does the magical  1-3 / 2-4 without temp problems.

The vort diving down and running underneath the closed ull on the 28th is still there and getting juicier every run. If the placement of the features is close to what has been modeled next week then this is then one to do it. Moreso than any of these convoluted gl / secondary crapfests that are queued up the next 5 days. 

The guidance wont pick up on that feature well until much closer because its being overshadowned by the dominant low over the lakes/New England.  I still think there is some potential for that to become more significant as we get closer.

Who cares what he thinks, some people might believe his crap and we are informing them, and I am having a little fun with it.  FUN, remember the whole point of this board. 

 

One thing going forward, the GFS continues to school the Euro this winter on general pattern recognition and major synoptic storm track in the day 5-10 range, but once inside 100 hours the Euro has been leading the way with recognizing the specifics and nailing down the details.  The last several systems, in the 2-4 day range the euro has been the first to sniff out some major changes and the GFS/NAM tend to follow a few runs later.  This seems to be happening again with the New England event this weekend, last night the EC backed off significantly on that event for places away from the coast, and now today the NAM/GFS seem to be following its lead.  With all the "euro sucks right now" talk keep that in mind.  In the long ranges it has been a mess, but it is still picking up details in the mid range better IMHO.

the 0Z GFS did cut back on NE's total last night too and the 6Z went a bit further

NAM continues to struggle both long and short term vs. other models

Where is the active pattern you guys promised?

Look at the 240 hours Euro and GFS.  They have a HUGE PNA ridge, trough digging to China in the perfect spot... and a -NAO.  The biggest problem I see on both right now, is they are spreading out the energy.  Just looking at the 240 H5 on last nights Euro...something is so close to blowing up on the east coast, and it would be far enough south for us...but there is a vort right over us, another one at the base of the trough down near the gulf coast, and another one diving in the back side.  Now it is very possible that there really are too many vorts competing and they all cancel each other out and run interference and nothing happens.  BUt is is also possible the model is simply having trouble deciding which one will consolidate the energy and bomb out.  If one of those can become dominant and take over...we will have a storm.  That still does not guarantee anything, we would have to get lucky with track...but I do not believe the "nothing will happen" solution on the models last night.  I think something will develop in the March 1-10th period.

GFS has not been far behind, but it does tend to be a little shower to pick up on these changes, and the NAM is a mess with details, bouncing around with every solution.

The Euro ens mean past 240 has continued to just be cool/cold and dry thru 360.. still almost no precip in the US in that period.

Even the 12z GFS is fairly dry for that period, just some light stuff around the Lakes and intermountain West for the most part.  Has one low in the southern Plains that produces some decent precip.

funky run.. so different than last night with the big 500 feature. storm runs into block and decays just to our north.

 

Yea, I don't think we can read too much into this. This is a really huge shift in the ul's. My maps make my eyes hurt so I'm not going through the exercise of comparing panel by panel from 0z. Just something to watch. Oh, and how about the vort down over ok/tx border..heh...heh..

im sure that leftover mess around us will screw it up somehow. :P

What's an absolutely weird run. Decaying ull absorbs the vort in the south and creates a close 540 contour stretching from TN to LI. I think we can go ahead and toss this one. There is no freekin way it goes down like this.
