poolz1 Posted November 26, 2019 Share Posted November 26, 2019 GFS has 3 sub 990 coastal storms during the forecast cycle....and a 4th that is just too far off shore to count. Lets keep this repetition going.... Link to comment Share on other sites More sharing options...

Anyone who is used to my posts knows that I’m a very optimistic person when it comes to our chances, sometimes stupidly so. But seriously, have you ever seen us get s winter storm from a wrapped up low in Nebraska? I won’t even be here this weekend but I still hope for snow. I want everyone to get some fun. So can anybody give me some hope and a rationale that could support it for this event? Ummm...weather will do what weather wants to do? Given the GFS cold bias I'd like to see a couple other models get on board pretty soon.....otherwise cold rain is the better bet. Link to comment Share on other sites More sharing options...

LP08 Posted November 26, 2019 Share Posted November 26, 2019 Expected to see a better surface depiction after seeing this at 500. Does it have to do with the angle of approach of the ULL? I know most of out storms have it trek through the VA/NC boarder but this is moving more NW to SE as it crosses the area. 2 Link to comment Share on other sites More sharing options...

I've always had this question - do models actually suffer from this? I'd assume that each run has no "recollection" of what the prior ran show. Therefore, shouldn't it just show what is modeled regardless of the prior run? Mods and shadow mods - this was not intended to be OT. 1 Link to comment Share on other sites More sharing options...
Winter Wizard Posted November 26, 2019 Share Posted November 26, 2019 The surface depiction is just noise at this point, especially the GFS which had a totally goofy evolution. The features aloft have largely trended in our favor today in terms of seeing some front end frozen precip. The 500 mb vort depicted in today's ensemble guidance is close to being in a favorable spot for DCA, but would still need to be considerably farther south in order to get anything from the coastal. Otherwise, the best dynamics would take place farther north and it's a congrats SNE. 1 Link to comment Share on other sites More sharing options...

Feb 1983 storm had an oblong shaped positive tilt fyi. Was a phase job so a different beast but you are painting with a broad brush. Sometimes they can work out.

UniversesBelowNormal Posted November 26, 2019 Share Posted November 26, 2019 The Pacific pattern is moving.. MJO.. surprising from what I have seen. Switch to heavy +NAO in the medium dampens cold/-NAO chances as a sustainable Winter pattern (N Atlantic SST index). Pacific looks terrible.. Pac jet flowing up through Alaska.

clskinsfan Posted November 26, 2019 Share Posted November 26, 2019 4 hours ago, WinterWxLuvr said: I see this as possibly some light frozen in the beginning, mostly rain, ull thumps the mountains to our west, coastal gives the eastern areas a shot at some wrap around snow, but most of the northern va area is left with next to nothing. Don’t see this as a cad setup either. Not at all trying to be negative but my “reality” check tells me this is a no chance scenario for at least my local area. Eastern MD possibly but not for most of us. Not over for us yet. We can score some with the WAA before it shuts off. It really depends on that HP over the top for us. It is rotting rapidly on most of the models Goes from 1038 to 1026 on the high res Euro. Keep it pumping in the cold air a little longer and we could see a couple of inches.

showmethesnow Posted November 26, 2019 Share Posted November 26, 2019 Models are trending favorably for the period shortly after the Dec 2nd event. Below we have the GEFS 500s from 2 days ago. Notice the deep push southward of the trough. Cold, dry suppressive look. Here is the surface. Pretty unimpressive for our chances. What sets this look up is that our Dec 2nd storm quickly ejects northward and reinforces the low in northern Canada. Now we have today's run at 500's. Suppression is gone. What we are now seeing is the Dec 2nd storm is taking it's time and rotating up through the 50/50 region. What this is creating is a small bump up of ridging in the east (red arrow) and in response we are seeing NS energy getting bumped southward (black arrow). And if you notice the surface we are now seeing low pressures dropping out of Canada and southward compared to 2 days ago which had high pressures. The GEFS isn't alone. The EPS has gone through same run to run changes these last couple days as well. Below is the current 500's Though not as pronounced you can still see the same features now showing up. Now I am not calling for a storm at this time. Just noting that the potential has ratcheted up a good bit from just the dry/cold and a possible clipper advertised a couple of days ago. 1 Link to comment Share on other sites More sharing options...

Will clippers ever come back. I would like someone who knows to explain where they have gone Some mets are looking for their return this winter. As mentioned a while back, some pros and certain seasonal winter forecasts have mentioned better odds this winter of Alberta clippers, etc., would love a Manitoba Mauler that cripples the Northern Mid Atlantic. As for where have they gone, seems since we had that massive warming in the Pac a few years back , it has been sort of blah, just speculation really.
