Just read Steven DiMartino's thoughts on this event and the last couple of DT facebook posts and both signify how quickly things can change re: models. Both seem to "favor" the low being pushed OTS before making a turn north, DT likes his backyard being buried in snow and Steve D seems to think Philadelphia and area are on the north end.

 

This would make it seem as if LSV to be the only area to not get theirs. Shocker lol

Interestingly enough: Steve Newton at WTAJ in Toontown addressed this in his 7-day and said that right now it looks like a "wintry mix south of US 22". A few moments before he had noted that the models were trending north, however and that was concerning him.

 

Banter thread in Philadelphia asking about tossing the 18z GFS. Are there errors or is it just everybody hates the 18z?

Things were looking good, and the jinx comes in.

 

Now things starting to look bad?

 

I mean... you know...

 

It was never going to snow anyway. All day 5 dream storms are pipe dreams. Nothing looks good till it is actually on the radar. Enough of the bashing too. Don't appreciate it.

Well it has been a joke, but I mean... lol, you "go away" after being "frustrated by all this" earlier in the season and most places (except LSV) enjoy a nice Christmas week of snow. You return sometime around the February storm where you went to CT and ever since it's been pretty tame.

 

I'm not saying, I'm just saying.

Will you relax, Sally? It was a joke. Jesus. When you "leave" because you're frustrated, you should expect to get a little bit of ribbing when you return. Especially when you return during the period of an expected big storm (wherever it is) after a period of "nothing", as you called it.

 

My point is: calm the **** down.

Anyway, I don't want this to become the NY thread so enough of this.

 

 

Back to the 18z tossouts. Any specific reason?

It's an outlier, I guess. The ensembles looked pretty good.

 

It's also a full phase, but really late. The others have a partial phase. I think that means that it might come way north next.

Here's my thoughts on the 06/18z suites: Don't *toss* them out. At this point in time, I would hold them the same stock as the 00z/12z runs that actually ingest upper-air data from the various sites. The off runs are just reinitializations of the main runs with a lot of the same data. There are some differences between the fresh data runs, however. My point is, the main H5 energy is over in the Gulf of Alaska where there are few observing sites. This is the main reason that our forecasting abilities beyond 5 days quickly decreases. Until we get more observing points upstream, we will still be playing the "model-flop" game until better data can be ingested. Until that upper-level energy reaches land, we will play this game and there could be several weenie suicide watches. 

 

LOOK AT THE UPPER-LEVELS! We have favorable blocking (likely won't be an APPS runner), which is one of the few times this winter season we've actually had this. Let's keep level-heads about this -- big snow storms in C PA are possible in March, but quickly diminish throughout the month. For SC PA, the chances are even more slim. It'll be threading the needle for a lot of us for this to turn into a substantial snowfall, but I am feeling more confident that a "plowable" snowfall is possible within 100-200 miles of Harrisburg.

Pretty awful trends from the GFS. The northern stream becomes less and less involved with the southern storm. If there is no interaction/phase, it will cut off and move slowly east well south of our area ala 00z.

 

12z, 18z, 00z at Wed 12z:

GFS can be pretty bad at times with the phasing at this range
