Tulip Trouncer Threat - End of March/ Early April


Baroclinic Zone

Recommended Posts

My take on that is that the GFS' last couple of runs are really dropping the ball on the western N/A PNA related ridge flex, and that doesn't allow the northern stream to dig enough to get involved with the southern stream - like the UKIE especially having that two stream full phased scenario. Even something partial and less extreme would be fine but the GFS just does this from time to time, where it sees a naughty deal and suddenly makes it rate G for 3 days.

The upshot is that it has to come back if the storm is going to happen. Frankly, I don't remember the last time the GFS scored a middle range coup over every operational run. Hell, even the hugely longitudinal biased "GONAPS" model has a buckle bomb on the 12z run. All that, and these recent GFS runs aren't a good fit at all for the larger mass field modality.

The GFS ensembles looks closer to the ECMWF ensembles. GFS ensembles are significantly better than the Op at this range and show a 995mb low over the Benchmark at 168 hours....The Euro ensembles show a 999mb low over Montauk, NY at the same time.

How did everyone do in the Tax Day storm in 2007? IIRC I came away with around 5"

About half an inch to an inch on the front end and then some heavier snow showers after it occluded that would whiten things at times when they got heavy. I remember about 4-5 days out that one looked like a monster snowstorm, but it obviously ended up much further west.

Still kinda early, but the GFS is less amplified and looks worse at 72 hour EDIT: It actually looks like the southern stream and northern stream are more phased around hour 96...EDIT: This is Classic GFS at hour 138... really confused and forming 3 different lows around the southeast.. It looks remarkably better at 500 tho

WOW at 168-174!!! that shows the potential for this storm... complete phase... GFS slow and SE is prefect right now

Here's a pic from the 18z GFS around day 7-8

Wasn't there another storm this year that had this same look with a bowling ball deep in the gulf and we all though it would phase with the northern stream but never did????? I think it was before the Jan storms but I can't remember... I know a previous storm had this look though

GFS ens mean is very amped up...it tracks the low up over Philly and then into E MA from 156h to 168h. That would change most of NE over to rain.

What a dichotomy that would make for; one of the worst endings to one of the best winters of all time.

That ends up a cold rainer and I may rank this ahead of 2006 for miserable endings.

It definitely would be a terrible finish. But given how late we are, its probably more favored than snow right now. If it was March 15th instead of April 1st when this popped up, then the story would be different.

This is why I always maintained that I would have rathered a finish like last year; fu** the cold pattern at this point because it isn't worth it.

Low 14 High 30 here on Saturday.... What's that normal for about February 5th around here? LOL

The top few inches of the ground in open snow free areas had gotten muddy...no more. Frozen solid again. That was nice because the horse paddock area was getting ugly. My sister has been in FL and I have to feed those four beasts, the two dogs and two guinea pigs twice a day.
