Feb 1-2 storm threat

God that's super close...close enough to where this storm can't be completely tossed...hopefully this is the beginning of something and this idea continues through 12z tomorrow...otherwise this could become a complete forecast disaster...even if this signal remains constant through tomorrow's runs...it's still not enough to totally discount it but not really defined enough to make a distinct forecast.

isn't that right along the bench mark?

No, It’s a bit southeast. I was actually expecting to see it further NW based on the OP run but this is still too close to close the books on...esp with that trend in energy of dropping the trailing shortwave behind and injecting more energy from plains northern stream.

I don't like the EPS. Way too far SE. Individual members not encouraging.

Tough to believe this euro yet. Sell.

We're still at the stage where sfc reflection isn't all that important...the surface reflection is going to be dependent on the evolution of the features at H5...point is if H5 continues with these improvements...it will reflect at the sfc. Seeing the major differences in the evolution of the northern stream is extremely encouraging.

That one weenie 973mb BM bomb though....

cue James with a 50 sentence long post about how if the storm tracks over the Gulf Stream that is an extremely likely solution with as much as 12-18'' possible at the Cape with wind gusts over 80 mph b/c 500mb winds at the base of the trough approach 100 mph

And they're not minor improvements at h5 either. Major improvements. GFS from run to run was ridiculous. gfs_z500_vort_eus_fh78_trend.thumb.gif.409e68f407460a96782495a6c35f08f3.gif

H5 is definitely encouraging and we are d3 out from the 12z runs so we have some time to improve things, we've done it with a lot less lead time than this.

Only thing thats really annoying is this shit airmass.

Tenor of the season.  Even if a storm comes ashore, it will be precarious with that air

The airmass thing means very little to me. If the storm is halfway decent it won’t matter... if the storm blows... the airmass will be a factor

What's interesting is that the GFS has been doing that for the past couple days with that s/w flip-flopping from being high amplitude to low amplitude.

I think it's an encouraging sign to see it back to high amplitude now...assuming with each new set of runs the pieces are being sampled better...a hedge in this direction is excellent news. The only question is will this be consistent through overnight guidance. If the flip-flopping continues then it's really anyone's guess as to what transpires b/c the end result will be too close for comfort (in terms of having to issue forecasts with leadtime) and could go either way.

I'm just concerned with how deep that southern trough digs that's what's going to decide the fate of this storm.  If it doesn't dig as much it will allow that leading s/w to develop further north to give it the track you need.  Mean spreads are really low with the amplitude of that trough so that's where my cause for concern lies but model guidance also has a tendency to struggle with anything originating in Mexico so there's that to keep in mind as well.

Just wait. When this thing comes in full beast . I’ve been collecting names 

 

Color me skeptical.  If this were the Euro of a few years ago, I'd be intrigued.   If you're seeing your 1'-3' on Saturday morning, wake me up.

I can lend you one of mine if you'd like.

Funny thing was that Yesterday the 18z Euro head fake, had all the EPS backing you could want, and it still Lost it all again at 0z. 

Todays 12z Euro big improvement doesn't have as much EPS backing as last nights 18z had...but maybe this time it's the real Trend regardless of the EPS not being as enthused as last evenings were.  Kind of Ironic in that sense.  But we're closer in and the sampling should be that much better, so this is definitely encouraging.  We'll see where it goes in a couple hours on the next set of runs.
