Let's be honest here John - other than the occasional T-storms (which are awesome) spring and summer are generally pretty damn boring as far as interesting weather events. Winter can give you anything from blizzards, icestorms, sleetstorms, raging nor'easters ala Dec 92, big wind events, thundersnow, and extreme temp drops. Spring/summer -- backdoor cold fronts, sea breezes, heat waves, and T-storms. The first two aren't interesting, so that leaves only two weather events that are fascinating; I guess you can throw flooding in there, but that can happen in winter too.

And there is nothing better tracking a HECS dropping 25-30" of snow... a la Boxing Day or JAN 1996, PD II, etc.

Thundersnow is so much fun.

Things we can learn from...euro is the best for east coast storms....gfs is crap...ukmet and ggem are pointless to look out.....nam should only be used for temps in the summer....no reason to extrapolate it outside 84.... not bitter...just saying

Maybe they should just get rid of every model except the euro. No point really to ever look at anything else.

GFS might as well read the Day After Tomorrow, it is just about as accurate. NYC had a decent snow event during that movie and the only model that predicted that event was the ECMWF. The GFS said heavy rain and in the 50's.

Now to reality that one run of the GFS earlier the week put every one in a tissy for nothing. And last night's NAM pushed it back north only to take it back south, Lets not mention last weekend debacle; this winter's model runs are making us meteologists look like idiots.

I love how everyone seems so quick to dismiss the next threat, possibly a result of still being bitter about this past storm. The reality is, and I argued all along, this setup was not favorable. There was nothing realistically supportive of snow for our area. The signal at H5 was clear that the storm would be shunted east, by as early as Wednesday evening. The reality is, if you take what some of the models have shown for next weekend verbatim, well that setup is more conducive for snow in our area. Similar to this weekend there is a block (even if transient), but more importantly the positioning is much more favorable. The biggest factor is the strong ridge out west. This allows the trough to amplify as the northern stream energy is forced to dive down into the base of the trough and phase with the southern stream. The ridge prevents the northern stream from either racing east or keeping the flow oriented w-e and progressive. Cold air is also available and able to drain south. That being said, such a setup is not the nicest I have ever seen and it doesn't scream snowstorm, but it sure as hell is much more favorable then the current setup. I just simply wanted to point out these details to those being so pessimistic and dismissive, especially since many of them were the same people I saw being positive about this past setup when it was about as horrid as it can get.

It's a moderate Nina. There's either blocking, upon which we have a shot, or just an absurd confluent pattern with a +NAO, upon which we have no shot, or no block/no confluence, upon which any real storm will cut to the lakes. Just the facts of reality in this pattern. We need a real Greenland/Baffin Bay block before we can really bank on a snow threat. Anything less than that's already an almost guaranteed fail. Winter patterns tend to repeat themselves, without major changes in the overall pattern. That map shows a general repeat of the overall pattern, so it's almost certainly a fail. When it's still showing this 72 hours out maybe, it'll be time to listen.

And yeah, I'm bitter. :(

That map shows a similar setup to this event, except a few key differences that this time around could have been game changers. Just checked the euro, although it didn't produce a storm because the phase didn't come in time and energy goes OTS, its depiction at 156 is very favorable. Unlike this time it has a strong ridge out west, which in my opinion could have made all the difference with this storm. This winter has been unfavorable, but if you can recognize setups that are different, then you can find the potential. If the features modeled on both the 0z gfs and 0z euro are true and do occur, then I would say there is definitely potential next weekend. I think if the models stick to this idea, then by Tuesday I will be getting louder. 0z euro at 156 is nice, strong ridge out west, energy diving down into the trough with a ton of southern stream moisture available and the hgts starting to rise on the east coast. Also has a nice block. Anyways I am getting ahead of myself, my only intention was to point out that if people could somehow have been excited about this past setup, then it is foolish to already be dismissing next week. I don't want peoples frustration to cloud their forecast. Although I think peoples excitement this past storm was sparked by a few model runs, but we must keep in mind regardless of what a model shows, does the pattern at H5 support such a solution?
