We need the GFS to cave and then one more trend west tonight from the other globals and I think you could be looking at a 2-4 type storm for DC/Baltimore with more east 95. If the trend stops or we start trending east tonight then I would be very suspect of getting anything west of the bay. However, there is no denying that pretty much everything has trended west except for the GFS over the last 24 hrs.

Bob, did the NS kick the storm out again?

The track up by the NE did shift west. Not by much but it was a shift. Their issue is the low center is still too far east and the northern stream still messes up the dynamics on the western side. Overall the only difference to the NE was a slight shift west in track but the upper levels inhibit the western side. Ultimately, the entire coast is rooting for the same thing. Tuck the low closer to the coast. It's that simple (especially in our area).

We have a tough set up,  but honestly we could get more than NYC maybe ( that would be ironic )  with the progression of the upper air feature .

Counterpoint... (though he's focused on PHL and NYC)

 

He did mention that we should root for a slower northern stream and stronger southern system that stays separate long enough.   Here's to hoping the trends continue and we get Nam'd in an hour.

Not sure if posted but Geps looks real nice and west

It's so frustrating the whole upper level pattern isn't a few hundred miles further west. What a huge east cost hit this could be. Very small in the grand scenes of things but yet so far away...lol

I asked this only because I find you to be so knowledgeable and so I really like to hear what you have to say. It's nothing to do with keeping score to see who is right or wrong or whatever. More like trying to validate my feelings of still being in on it and whether I'm off base and just wishcasting.

I had no problem with you asking and I didn't take it the wrong way.  Not sure why it bothered Mitch.

That cluster on the west side of the GEPS is close to a money track 

Speaking from a purely statistical approach; Wouldn't it be prudent to throw out the 5 or 6 most outlying members to gain a more accurate representation of the data?  If that is correct and I am reading this right, wouldn't there then be more argument for the westerly members being the most numerous?  Please excuse me if my noobishness is showing through.  Trust me, I have a ton of other questions that I haven't wanted to bother anyone by asking.

Since this is a fast moving, progressive, and dynamic setup it's best to follow trends as leads shorten. The GEPS picked up on the possibility something @ 12z that was absent at 0z. Look at the northern stream energy to the NW. Much slower. This keeps the "kicker effect" muted at our latitude.

Yes, but if you look closely, it looks like there are 7 members pretty far west and then a bunch pretty far east and the combo gets you the mean low pressure center, which leads you to believe the low is likely to either be on the west side or east side and not where it's actually depicted. At least that's my understanding looking at that.

Thanks Bob!  I am looking at this loop and my noob eyes tend to like what they are seeing.

Based on verification scores, the GEPS at 72 hours has roughly as much skill as the GGEM.  For some reason the GEPS have been performing relatively better in the long range, and the GEFS have been doing better in the short range.  I suspect it's because the GEFS are more tightly clustered around the op, which is good in the short range, and the GEPS have a better spread, which pays off in the long range.

I don't think so, especially with so few data points.  The one caveat to the GEPS is that the individual members use different physical models, so they have different skill.  This is arguably good from a statistical standpoint (less correlation among the members), but I don't know which of the members are most skillful.  Let's say its the ones with the western tracks.  Why not.  :weenie:

I guess there is still a little time. 

Of course there is. It’s funny how those that we’re “out” now have half a piggy toe back in. No matter how good some are this is exactly why most of use spend countless hours chasing, because we all know that there are so many variables....and very few absolutes in this game. It’s part of the fun.  Today’s runs (save GFS) and now 12z Euro proves my point (and I’m not saying it works out....I just know better than to to write anything close off at 4-5 days out. Am I surprised...sure, but we’ve seen things trend worse....and sometimes better over the years.

Just to recap: 

SREF's - Get the .25 through the cities. 

JMA - about .2 for the cities. 

EURO - .1 for the cities. 

GGEM - .15 for the cities. 

NAVGEM - get's precip into the cities. Not sure how much. 

GFS - Nada for the entire eastern shore pretty much. 

I'm really interested to see how the short range models deal with things as they start to come into range.

That would be me. And honestly, being out made it a lot easier. I might have to use this technique more often in the future.
