bluewave Posted January 21, 2019 Share Posted January 21, 2019 Figured we could use a dedicated thread to discuss any storm potential for later in January. 5 Link to comment Share on other sites More sharing options...
uofmiami Posted January 21, 2019 Share Posted January 21, 2019 Probably end up a rainstorm, as cold air will once again be an issue, if this storm does happen. There’s no high pressure in Quebec for cold air source should storm wrap up. 2 Link to comment Share on other sites More sharing options...

TwcMan Posted January 21, 2019 Share Posted January 21, 2019 Ridge isn’t in the best position for the coast and we’re lacking cold enough air. Hopefully we can fix that before the storm occurs. It’s a good sign having all of the ensembles showing the signal for this timeframe Link to comment Share on other sites More sharing options...

PB COLTS NECK NJ Posted January 21, 2019 Share Posted January 21, 2019 1 hour ago, bluewave said: All the available ensemble guidance indicates the potential for a phasing storm system around January 27-28th. This is one of the few times that the EPS, GEFS, and GEPS show this kind of potential in the 6-10 day range. We are still pretty far out in time for any specifics. But maybe we can use this for a dedicated new January storm thread. So the general January thread doesn’t get too crowded. I love Grand Planetary waves but we will need some luck to keep the coast all snow. I would like to see the ridge axis to be a little further east here so I can keep the center off A/C , but check out the moisture feed for this one as well. Big ticket storm for someone. 2 Link to comment Share on other sites More sharing options...

Also the trough looks like it has a chance to become negatively tilted - hopefully we can get a 50/50 low for this event - but the thing that is worrisome along the coast is the MJO in the warm phases Link to comment Share on other sites More sharing options...

No -NAO, no 50/50 low, no big arctic high in SE Canada and yea unfavorable ridge positioning in the west. The Atlantic is definitely a real big problem though. As some others mentioned, the lack of cold is a big issue Link to comment Share on other sites More sharing options...

It would be a dagger if the 15 days were well BN and you phased a moisture laden storm off the E/C and the coastal plain surged for 12 hours. Long ways off tho.

Ericjcrash Posted January 21, 2019 Share Posted January 21, 2019 This is going to be another week of torture. Going to have to thread the needle, if I had to venture a guess you'd want to be NW of Middletown and west Milford to cash in again but we have an eternity to trend favorably. Cold air will be hard to come by at that point even though we're currently sitting in the single digits or colder everywhere. I'd sign up for the paste bomb that the 0z Euro was but it's very borderline. 1 Link to comment Share on other sites More sharing options...

Biggest issue in my opinion is no -NAO block. If there was, this would be game on for a massive snowstorm 1 Link to comment Share on other sites More sharing options...

wdrag Posted January 21, 2019 Share Posted January 21, 2019 Hoping the phaser idea is right but I don't see phasing at 500mb, even as occurred this morning in NYS to allow us to have very deep cold air here today. I see 2 members of the GEFS that have an option for a closed low south of 35N, and no no sign, imo, of phasing closed low aloft south of 40. Doesn't mean it cant happen but i see a fast mover out of the se USA up the east coast, w so many details to remain. Wont comment for a couple of days til this gets a little better defined. Here's WPC take issued at 1AM, basically for Sunday into Monday. Note GA 10-29% chance of 2+inches of snow via .25 w.e. frozen. The darker green is 30-49% ie... thats 51-70% non occurrence. I like the WPC idea, as an outlook...not a big big one but definitely a hazard producer and associated travel issues Sun-Mon, but from my s standpoint, more likely west of I95. 1 Link to comment Share on other sites More sharing options...

The eastern trof as the system is developing back across the western Gulf is too sharp and narrow for this to go west of the Apps 1 Link to comment Share on other sites More sharing options...

That would be the nail in the coffin for me. Some years it just don't wanna happen. We are seeing that we are missing the components, from what I am reading here, to make for a decent snowstorm for a lot of us in the subforum ( not all ) and so the likelihood is that it will not be a big snowstorm, or even a snowstorm. As a nonpro I am not clear on why we never seem to get blocking when we need it, but there you are....maybe some other factors can make it work. See photos on the news of DC, KY, NE all with snow OTG, and nothing here of significance. Oh well, that makes some, ok many, ok most, people happy I guess. 1 Link to comment Share on other sites More sharing options...

As some others mentioned, the lack of cold is a big issue There are indications of a ~1040mb high in SE Canada on most of the guidance, but the timing is variable due to the northern/southern stream differences. On the Euro, the Gulf low attacks the high from the S. Looking back at bluewave's initial post - the GEFS and EPS have a stronger high there than the Canadian ensembles.

purduewx80 Posted January 21, 2019 Share Posted January 21, 2019 Will be interesting to see how this evolves the next couple days, but the majority of ensembles at 00z favored something closer to the Euro w/ the 500 wave cutting off somewhere over the Gulf Coast/Southeast. We saw this with the system a few days before Christmas where parts of the Gulf Coast/SE set new record low 500 heights. If something like that verifies (high heights Canadian maritimes, low in the SE CONUS), obviously this will be another high precip event for the region. Some hints of an east-based -NAO which would favor inland areas seeing highest risk for +SN. At least there is good agreement the EPO is in better shape. Clusters of 500mb anomalies valid Sunday evening below. Link to comment Share on other sites More sharing options...
