Very real. Much more real than the weekend threat. Classic overrunning/redeveloper into coastal pattern. We even have some sort of a block developing to the north, too. 

Right now it looks like it yes, but storm is 10 days out. Also, with the shortwave being in North Pacific, and gfs showing slight improvemen tonite, I would hold off on calling weekend non threat.

Cutoff block in the prime spot over the davis straights. That'll get us out of this progressive pattern..HM has liked this date for a while.

Just a couple days ago, we were saying this one could be a triple phaser. I'm not buying anything that far out. Does it show a big cutter like the gfs prior to that. 

 

As far as the cutter the gfs shows after this threat or no threat, that would be a completely different evolution if this storm (17-18) materialized. In fact it would probably be another storm for us as it would likely be forced further south.

It does show the big cutter, but that's what helps set the pattern up in the first place. The pattern for the weekend was much too progressive and there were so many pieces of energy involved...next week it's more simple/textbook in that we have a strong piece of energy crashing into the west coast with rising heights behind it, along with a huge 50/50 low/pesudo PV even from the departing cutter, ample STJ moisture, and a block in the Davis Straights. 

 

Of course, yes, it is 10 days out, but a general broad signal certainly does favor this time period. We'll see.

Cutter still looking great on the GFS. Will be nice to get some moderate to heavy rain in here and clear everything out. We also need this to setup the threat a few days later.

This will not be a cutter with a 50/50 low,Negative NAO and strong high to the north.

As we progress it will head for the coast or redevelop.

There's a semblance of a 50/50 low for both events, especially the second one so I wouldn't be surprised if the gfs trended further SE with both. 

 

These threats next week should probably get their own thread soon. As far as this current one goes, maybe a few snow showers, it's going to be east unfortunately. With all of these threats out there, we could have scored on every one of them if we had some blocking in place.
