Bob, check out the vort track on the Euro for the 17/18th storm. Looks really healthy and an ideal placement (VA/NC border) for us, right?

It's leaves too much room in advance for the slp to end up in the TN valley for it to be really good. As is we can work with it. A low tracking across MO into TN isn't ideal. We like them to come up from MS or AL.

Yes, the secondary low as depicted isn't ideal.  When you say it leaves too much room in advance, what's something to look out for with the vort that could help the secondary either transfer sooner or not make it as far north?

Let's get this under 120 hours. Cant believe we're still at day 10 lol

There's a 994 low due east of you at 216, so while it's futile to even discuss timing details this far out it's simply oscillating the time frames based on what vort if focuses on, and not necessarily getting pushed back constantly past day 10.

12z gefs, as far as the overall pattern goes, looks great right through the end of the run imo.  Heights in w Canada up thru AK are increasing toward the end of week 2.  -AO and -NAO continue.  I can't imagine we don't hit a nice stride sometime in the next few weeks.  

 

This pattern will either be a tough lesson for this weenie or will produce nicely....like an h5 pattern like that should.

For those of you with access, go to the 500mb means for hr 216 eps. Lowest pressures centralized between Richmond and central NC. That would be a nice spot to have it.

eta: Here is the tropicaltidbits image of it!

Day 10 suggesrs, however, that it's exits due east and does not come north very far up the coast.

Hey Ian. Notice anything on this 10 EPS map? I do. There's that odd trough at the North Pole that I pointed out to you strangely present on the 5H composite maps you posted the other day for our biggest snowfalls. Just sayin'. Lol.

It could be a signal for the 1/21 event...

12z Parallel Euro takes the 17th threat and turns it into a GL cutter which then spawns a secondary off the NJ coast.  For comparison purposes, the Euro-P 0z had a similar solution of today's 12z Operational.

but completely opposite of its own op, correct?
