showmethesnow Posted December 25, 2018 Share Posted December 25, 2018 Overnight GEFS is really going to town with the EPO/PNA ridging. If that is accurate we are probably looking at a major cold shot in the extended. Probably much colder then what it suggests at this time. Unfortunately it probably also means major suppression as we see no SE ridging nor WAR to combat the deep NW flow. eta: EPS is also starting to ramp up on the EPO/PNA ridging as well.

pasnownut Posted December 25, 2018 Share Posted December 25, 2018 Fv3 overnights did not look horrible for the overall pattern once beyond this weekend. Ridging in west pops and trough digs in the east as we turn the calendar. I'm just going to leave it at that cause its Christmas and I'm considering that a good gift, and not a lump of coal. Out to the end of the run, the 500 maps are definitely bringing the cold. Hope ya'll have a great Christmas. Link to comment Share on other sites More sharing options...

showmethesnow Posted December 25, 2018 Share Posted December 25, 2018 One thing we are seeing on both models, which IMO is a big positive, is that they are and have been moving towards the idea of placing part of the pv into northern Canada towards the Hudson Bay region.

That would be extreme cold as a portion of the pv gets displaced south over the GL. Though quite often this can be a very cold, dry setup as everything gets suppressed south it also can bring its own fun as energy rotates around that pv. Think possibly high ratio, dry, wind blown, in the teens snow. Actually have had a couple of KU's (miller Bs) with a similar setup though it escapes me which ones at this time. Maybe I will dig into my Kocin books a little later. Link to comment Share on other sites More sharing options...

Yeah the EPS has gone bonkers on the Pac side the past few runs, while losing the NA ridging in the LR. It does look cold. I prefer the GEFS look up top, and maybe the EPS will trend that way. Per the weeklies it gets there eventually. Link to comment Share on other sites More sharing options...

Like I always say get the cold established then we can set the stage for frozen as the pattern cycles. Cold antecedent air masses are probably the number one most overlooked or taken for granted ingredient for a winter storm. Link to comment Share on other sites More sharing options...
Wonderdog Posted December 25, 2018 Share Posted December 25, 2018 FV3 gives us three opportunities and we miss to the north and west on the first two and then miss to the south and east on the third. Call me skeptical but even with our usual lack of luck, I find it hard to believe we get shut out, especially on the 3rd one. Link to comment Share on other sites More sharing options...

Definitely should start getting true threats to discuss in the next few days. Link to comment Share on other sites More sharing options...
CAPE Posted December 25, 2018 Share Posted December 25, 2018 This is a nice h5 look and offers potential for just beyond the NYE event, which still favors rain for most here at this point. We have NA ridging, a daughter vortex, and cold air now becoming entrenched. There is just enough of a SE ridge to offset what might otherwise be a suppressed system. It is suppressed on the op run, but not as much on the ens mean. Link to comment Share on other sites More sharing options...

AfewUniversesBelowNormal Posted December 25, 2018 Share Posted December 25, 2018 Long range GFS looks really good, under the -EPO is a GOA trough, perfect for snow. -NAO on long range models probably won't verify, it seems that everytime there is a stratosphere warming the models show this at 500mb in the long range. If it verifies, we could be in SECS heaven. Link to comment Share on other sites More sharing options...

AfewUniversesBelowNormal Posted December 25, 2018 Share Posted December 25, 2018 There is definitely some mid-latitude warmth in the cards right now. If indices become favorable for cold, expect the WAR to pop which is favorable for coastal storms. Link to comment Share on other sites More sharing options...

cbmclean Posted December 25, 2018 Share Posted December 25, 2018 A few weeks ago there was discussion on here of the euro overdoing lows in the Southwest. Fast forward to Christmas. My wife got me Tim Vasquez's Weather Map Handbook. One the first thing I noticed when flipping through it was this starement: "The ECMWF is notorious for overdoing or overpopulating cutoff lows, particularly in the Southwest US." You guys know your stuff. Link to comment Share on other sites More sharing options...

NorthArlington101 Posted December 25, 2018 Share Posted December 25, 2018 Couple of GEFS members still have a light NYE event. Not a majority, but that idea still exists. More look promising for just after New Years... some on the first, some on the second, some on the third. 31st-3rd certainly looks like a window of opportunity.

Yup. I liked the h5 look on the 6z run this morning, and then the 12z op run followed with a nice tease. The 12z GEFS look continues the intrigue.
