Does seem further SE though. But pretty similar.

good old fashioned model war over this one, hopefully GFS op bleeding to Euro progression signals a coming surrender though.

Also for the 20th, precip on GEFS indicates the GoM is going to spin something up. Obviously as depicted it's OTS but given the beautiful bigger picture, hard to complain at this range... good to know there's potentially energy around, then got to get it in our neighborhood.

Baby steps. Still reeling in the precip field from the sea.

Intrigued to see how GEFS will pick up on the euro idea. If the OP is starting to cave, should hopefully see some nice members at least.

Trend is friend! Trend is friend! Trend is friend!

Would love to see the members on that, to get a spread that good on depth maps in particular is encouraging.

IF Tuesday is going to be something, the bar for me is simple - drop enough snow to survive the relative warmth Friday (a bit Thursday too) and keep the grass covered! Then we can get into "the look" period with even deeper cold and lock that snow cover in for a bit... not accounting for any added snow!

Didn't realize it initially but GEPS has some real cross polar flow in the picture for the 20th, ridiculous cold.

You can see the trending signature on the precip map of the storm amping up off New England. But definitely more juiced overall even before that, hopefully that trend contributes to it coming in a bit more NW over time.

Slow and steady trend on the TPV. And setting up nicely to force the low into the 50/50 spot.

Jeez were nearly a week out with a storm in between and you’d think snow miser just came through and told us he has cancer and left his estate to heat miser. We’ll see what happens but at this point I won’t look a positive trend in the mouth

I'm personally starting to let that threat go. The window where it looked like we were moving towards a workable solution included the TPV hanging back longer in the Pac NW while a weaker lobe popped out and went on its own, plus there was a wave sliding off the coast as the storm approached to fist fight the ridging ahead of the event. None of the models show that now (edit: Operational models, that look is not entirely gone from ensembles), either bringing back strong ridging in front of the event or making the TPV come forward and phase.

So far GEFS also seems to want to show that North/South stacking of vorts.

GFS just too buddy-buddy with the energy pieces here compared to GEM, far stronger, and kicks out the leading shortwave across the lakes/Canada too quick.

GFS jumped big towards the TPV getting involved with the 13th wave so it cuts. Need more separation if it's going to work - had been trending that way but 18z and 00z have reversed it.

It’s only the ICON, but it trended towards popping out a vort into the plains ahead of the energy for the 13th. Looks very similar to the GFS progression, less heights immediately in front of the big western blob of energy. Can’t say it is in the transfer camp until the longer 00z run verifies but that leaves only the UKMET being stingy with that vort, keeping it further north.

Hard pressed to even nitpick that…

Dream scenario: lobe continues to trend SW, slips under a growing block, gives us a taste of flakes/appetizer before we set up under the big chill behind it.

Look at the surface temp trend next Sat, 12z. On EPS. The Friday/Saturday storm is bringing in the chill behind it… just needs to reach us.

Euro trended south for next weekend as well.

In that reading, could next Friday’s wave, if it shoots off the coast further south, open the door for that slip to happen?

Danger, anecdotal blend of models ahead: Am I crazy to think that blending the GEM and GFS look on next Friday/Sat might work out for us? edit: never mind, was looking at a 00z GEM panel. 12z is closer to 12z GFS.

To expand on next Fri/Sat, GFS trend has been pretty evident towards colder on lead-in. Over last 3 runs, freezing line has gone from being horizontal right through central PA, to reaching well into the WV apps but certainly not a strong, deep cold or anything yet. Baltimore went from 45 to 41. Energy for the storm is getting more separation from the deep pac NW vort. Little vort pops out from the lakes earlier and flattens the ridging over us some. More ridging over central Canada overtop the storm rather than all out front.

Trend for Friday/Saturday on GFS getting closer to a thump but would require a lot of temperature improvement and further moves SE
