Having a TPV under the block does more than just compress the flow. It spins off spokes of energy that can phase with and sharpen the primary wave in time for a coastal to get going south of our latitude. It actually encourages the wave to amplify/dig more, and take on a negative tilt.
-
The Euro was doing this a few days ago then trended away from it, but yeah I don't think we want the shortwave to be an entire TPV lobe lol.
-
Look at the 6z GFS run. I made a post on it earlier.
-
The runs with the better outcomes have lower heights there yes.
-
I think this is probably the best panel to see the differences. Continues the trend of ejecting less lead energy eastward underneath the NAO ridge.
-
In progress.
-
At this juncture the depiction on the means is reasonably close to what we want, but plenty of details that will determine the ultimate outcome remain unresolved.
-
-
A bit of an increased indication of low pressure to the NW on the 6z GEFS.
-
Pretty epic run. A weak wave with some light snow on Xmas day, and it has the storm on the 27th.
-
Verbatim it's a big hit along I-95 and east. NW burbs would see several inches.
-
-
6z GFS does things with the initial vortex- more symmetrical and turns it under the block instead of it sliding out towards 50-50. A piece of energy rotating down phases with the main shortwave.
-
2.12" total.
-
The initial wave sliding east under the NAO ridge towards 50-50 is weaker, and more energy is dumped into the main shortwave- so a stronger shortwave with less resistance above and it doesn't dig as far south. Fairly subtle differences in the wave interactions can make big differences in the outcome.
-
Somewhere up that way. Near Allentown iirc.
-
Damn I remember him. That was before we had sub forums. PA dude right?
-
Once some get a sniff of the good stuff, concern sets in that it can't be real, and rationalization begins.
-
I would say there would have to be significant error in the modeled PNA state to end up with a classic cutter.
-
Whenever I make an intentionally dense post I think of him for inspiration.
-
Seen it plenty of times in our prime backloaded winters. Snow otg in early March survives nicely when temps are in the mid to upper 20s on a sunny day. Ofc at most that lasts one day.
-
Even that cannot overcome the searing hot Feb sun bleeding through the dense clouds.
-
Imagine not understanding that our inability to stay cold at this latitude is why snow never sticks around long.
-
Saturated soil going eat the snow. Ground must be a frozen brick. Need advertised Barney cold or I'll worry even more until the advertised snow doesn't come.
-
True soaker. Overflowing ditches and water laying everywhere. Need this ground to dry up some so all that moist soil doesn't eat all the snow to come next week. 1.77" so far
