Maestrobjwa Posted November 28, 2018 Share Posted November 28, 2018 @psuhoffman On another note....thank you for the in-depth explanation! Wow--between you and poster in another forum giving me a dissertation about whether there was any history of the blue blob and the ENSO...I've been to school today! Yes...modoki truthers...certainly seem to be of those out there, lol But interestingly, I had just read something in another article yesterday about 2009/10 not really being "modoki". Now, I take it modoki is thrown around as being an automatic snow-indicator (which draws the ire of the truthers? Lol) Link to comment Share on other sites More sharing options...

Nice high pressure set up to our north and northwest. Really good look. Too bad it's still 10 days out. Hopefully we still have the same look in 5 days. 1 1 Link to comment Share on other sites More sharing options...

MillvilleWx Posted November 28, 2018 Share Posted November 28, 2018 EPS control was a pretty solid look with the H5 trough progression cutting underneath, then taking on a negative tilt around our latitude. HP building over the top as the low pressure slides up the coast. This is one way y'all can score in the Day 10, but current progs show that southerly flow ahead of any storm with the retreating surface high initially will cause the thermal layer to have some issues for most of the sub-forum. The overall longwave pattern is ripe for that time frame with a pretty stout H5 closed ULL/trough entering the west coast around Day 7/8 according to the GEFS and EPS 500 hPa Mean. Interesting to note where it also enters the west with the base of the trough rolling through North-Central California. That's a good place to a wave move onshore and exit at or just south of our latitude. A little more south could work as well, but beggars can't be choosers. As many in here have mentioned, the time frame is worth watching. I'll be keeping close tabs on it as well as that system may actually affect our weather out here. 3 Link to comment Share on other sites More sharing options...
Chris78 Posted November 28, 2018 Share Posted November 28, 2018 Looking through the individual EPS members there's some heavy hitters in there. Also a good amount of southern sliders. I like seeing all of the southern sliders at this range. If there is an actual storm I doubt suppression will be our concern. 3 Link to comment Share on other sites More sharing options...
Bob Chill Posted November 28, 2018 Share Posted November 28, 2018 I can easily see how the storm on the 5th could work in our area. Not very likely but I wouldn't be surprised if more confluence starts showing up and the track moves east over the next few days. Move the departing 50/50 south just 150 miles or so on this panel and it's snowing here... 4 Link to comment Share on other sites More sharing options...

Nice post...Reminds me vaguely of the Feb 5 2010 setup.. Let me first say though that I am not saying this will turn out to be a similar end result, just noting on the similarities @ H5...Here is the 18z GFS @ 213 hours and then h5 from February 3rd 2010 (2 days before the event)....Note how similar the ULL/trough energy coming out of the Southwest is. What would be key here is to get the N stream to cooperate like it did in 2010. * I tried posting images but I might be at my max...just going to upload them to an image host....annnd here we go https://postimg.cc/hzjh6mTJ https://postimg.cc/k6pDm5vT In 2010, that event that gave you guys a few inches of snow on feb 2-3rd was the catalyst for locking the cold in for main event. Need something similar to happen here for the DEC 8-10 POTENTIAL. 1 Link to comment Share on other sites More sharing options...
Bob Chill Posted November 28, 2018 Share Posted November 28, 2018 Not a fan of the northern stream vort on the 18z F3 with the d10 potential. I wonder if that's behind a number of ens members with a good track and mostly or all rain. Obviously it's way to far out to worry about something like that now but it's something to watch as the days go by. Seems like there's 3 camps with the possible storm. Southern sliders have no northern stream interaction and suppressed flow. Rainers or west tracks have northern stream influence. The good solutions either have hp over the top or a perfect track between the 2 hps with limited or no northern stream interaction. Link to comment Share on other sites More sharing options...
Bob Chill Posted November 28, 2018 Share Posted November 28, 2018 This panel is a good visual. The ns vort helps raise heights in front of the ss vort and screws up the mid levels. And before someone comes in to tell me not to take a d10 op seriously... I'm not... Just pointing out something to keep an eye on as the whole thing evolves. Obviously there's no way in hell an op is going to nail anything in the northern stream this far out. 1 Link to comment Share on other sites More sharing options...

Slow the northern stream down a bit and drop it in behind to phase and boom ! Could be fun. 1 Link to comment Share on other sites More sharing options...

After last winter, I don't even wanna see ns even TRYING to screw something up even on a d10 prog (hopefully that potential vanishes in the next several days)...that L in the north is burned into my memory, lol Link to comment Share on other sites More sharing options...
frd Posted November 29, 2018 Share Posted November 29, 2018 I stumbled upon this just now, but read about this issue earlier today from @Typhoon Tip in the New England forum. I say beware of the Euro weeklies because of this. 1 Link to comment Share on other sites More sharing options...

Remember when I mentioned the pattern is also good for a southern slider? We may need some sort of tug from the ns to be in the game or it will miss south. These types of fine details are usually never worked out until the med/short range. Just something to keep an eye on. I don't get too invested on any storm until 5-6 days out at the earliest unless it's a Jan 16 type of deal. Ensembles still have large spread and any one of the solutions has equal odds. 1 Link to comment Share on other sites More sharing options...

Heisy Posted November 29, 2018 Share Posted November 29, 2018 00z EURO looks really good on my freebie maps @ H5 but without precip it is hard to tell...temps are more than fine though. Link to comment Share on other sites More sharing options...
Heisy Posted November 29, 2018 Share Posted November 29, 2018 Also, dont want to get too wound up into the Dec 8-10th event since I’m starting to feel like this 5th event has legit legs, but the issue I have with it is the timing. If the energy ejected from the SW faster it would be better, but the models right now are taking too long and we lose our cold source. Link to comment Share on other sites More sharing options...

The high is in a bad spot though. One departing and one coming in behind. That might mess it up but the antecedent air mass is still plenty cold as it's approaching.

Scud Posted November 29, 2018 Share Posted November 29, 2018 5d tease looks much better on Euro. General 1-3 inches of snow. 10d still there, slight westward wobble.... Ingredients fo 5d showing up nicely on NAM. Cold air heading south and east behind departing Great lakes storm. Mid level energy coming out of southern Rockies. Old frontal boundary NE Gulf. Sweet...

showmethesnow Posted November 29, 2018 Share Posted November 29, 2018 EPS snowfall maps. 1 inch line mean gets to around the MD/PA line for the Tues/Wed storm. Roughly a third show snow for portions of our region with most favoring around the Mason Dixon. The Dec 8-10 period has the 3 inch mean right around the cities with the 3 1/2 line just south of the PA line. Some nice hits in the mix for the DC/Balt region with just under half of the members getting 2+ inch through the cities. Control run is a winner with 1 1/2' + totals for the cities with 2 foot just to the south of DC. Shows a double whammy with the initial storm and then a secondary off the coast that pops up immediately afterwards from energy left behind.

BristowWx Posted November 29, 2018 Share Posted November 29, 2018 Pretty clear what Chill mentioned yesterday in FV3 0z to 6z...for 9 Dec. that low on 6z draws it north. Suppressed on 0z pressed south like a canned ham 1 Link to comment Share on other sites More sharing options...
