hardypalmguy Posted December 16, 2022 Share Posted December 16, 2022 EURO wrapping this thing up like a top. Look at these temp gradients. Warm air pulling in from the north and cold air from the south. Looks fun. 1 Link to comment Share on other sites More sharing options...
RCNYILWX Posted December 16, 2022 Share Posted December 16, 2022 The 12z EPS is rolling out and the operational ECMWF is the most extreme solution SLP wise that far south vs any of the individual EPS members. EPS did trend more toward the general idea of the operational run vs previous couple EPS cycles though in handling some of the key mid-level features.That 12z Euro run is without exaggeration the wildest non fantasy range model solution for a winter storm in this area that I can recall in my time here (since July 2010). But the first paragraph highlights why these operational runs still need to be taken with a large grain of salt at this lead time. The potential in the pattern next week is certainly high as we've been saying, but the complex evolution will take several more days to resolve. Edit: From the New England sub (where the mood is as you'd expect after the non GFS runs today), look at the change in the ECMWF at the same valid time of 06z Friday 12/13 between the 12z runs yesterday and today. 7 2 Link to comment Share on other sites More sharing options...

Powerball Posted December 17, 2022 Share Posted December 17, 2022 18z GFS was back to being a nice storm for parts of the subforum. The Ohio Valley and Eastern Lakes got slammed. Link to comment Share on other sites More sharing options...
SolidIcewx Posted December 17, 2022 Share Posted December 17, 2022 This shall be fun. Quite surprised on the runs. As someone who works outside would be an awesome chance to take some pictures with the bit of wind potential 2 Link to comment Share on other sites More sharing options...

Probably because verbatim, for the vast majority of the subforum, it's a bit too strong and too far NW. Most of Wisconsin, Iowa, parts of N. Illinois and parts of Minnesota do well, but everyone else (Chicagoland included) sees mostly rain or mixing issues followed by massive dry slotting. 1 Link to comment Share on other sites More sharing options...

On that note, warm air occlusion and 925mb winds of 65-75KT on the W/NW side of the storm system. About as a significant solution you can see around these parts. Check out some soundings west of the storm system as well, tropopause down to near 700mb. 2 Link to comment Share on other sites More sharing options...

Stebo Posted December 17, 2022 Share Posted December 17, 2022 I have no idea what could happen, there literally are several different solutions and every run of every model comes in with something new. I'd lean cutter with an occlusion just not as far west as the current storm, but beyond that I have no clue. We probably wont get one at least until Sunday at the earliest. 3 1 Link to comment Share on other sites More sharing options...
Radtechwxman Posted December 17, 2022 Share Posted December 17, 2022 Funny b/c gfs was the model originally showing a GLC and really wound up sfc low for many runs and then it started bouncing all over the place. Now euro is the one showing this with some support from other global guidance. No way we will get something as extreme as 12z euro but even half that would be amazing. Gfs seems like it is baby stepping towards its original solution. Would like to see it cut more west and track a little more north than 18z showed. 2 Link to comment Share on other sites More sharing options...

The Ohio Valley and Eastern Lakes got slammed. Glancing blow for SEMI. SLP's in TN and WV just don't deliver here as you well know. Still chasing my 2" Grinch storm, lol. E of me, now W of me again. S of me, maybe N of me, or just the old middle finger mega-dry slot this region is famous for. CPC still has me in a risk for +SN/+Wind/-Temps so too soon to throw a towel. This area is certainly the longest running CWA at this LAT without the "B" warned event, and by miles compared to others. I think last "B" headline to deliver was Jan '99. Jan '05 may have been a close call. Been a while that's for sure. 1 Link to comment Share on other sites More sharing options...
Radtechwxman Posted December 17, 2022 Share Posted December 17, 2022 Gfs being stubborn. Clipper like system to nor'easter transition. It's not wanting to do a GLC. Either it will be the lone model right or completely wrong. Link to comment Share on other sites More sharing options...

Dry slots happen in most storms but it's not like any areas prone to them more than another. As for blizzard? I think the last one was February 2003 but blizzard is blizzard is more about wind and visibility. I'm totally fine getting a big storm without blizzard criteria. But if it happens, bring it 1 Link to comment Share on other sites More sharing options...

Either it will be the lone model right or completely wrong. The other problem is the GEFS is still too non dispersive to glean much from it when the operational is quite different from the other globals. It's common for ensemble runs to shift in the general direction of the op, but the GEFS hugs closer to the op than the EPS tends to, which does a better job capturing the full spectrum of potential outcomes. Part of that is having only 30 members vs the EPS having 51, though non dispersiveness has been a persistent issue over the years with the GEFS. You can see the issue just comparing the 18z and 00z GEFS. There was a wholesale shift toward the op.

Definitely eager to see how this evolves over the coming days. I wonder if euro will hold firm or will cave to a gfs like solution with a coastal storm and only a glancing blow here from northern stream energy. 1 Link to comment Share on other sites More sharing options...

Didnt we have repeated GFS vs. Everyone standoffs last year with last second (within 48 hr) caves repeatedly by the GFS? We will see if the "upgrade" does anything, but certainly not putting much weight in any solution (and even less with a GFS outlier). 4 Link to comment Share on other sites More sharing options...

I think we did but can't remember if it was gfs caving to euro or euro caving to gfs. Probably the latter Link to comment Share on other sites More sharing options...
tim123 Posted December 17, 2022 Share Posted December 17, 2022 I think the gfs fairly consistently beat the euro last winter Link to comment Share on other sites More sharing options...
RCNYILWX Posted December 17, 2022 Share Posted December 17, 2022 I think the gfs fairly consistently beat the euro last winterThat's inaccurate. Just to give two examples, the ECMWF/EPS far outperformed the GFS/GEFS for the February 2022 winter storms.

chuckster2012 Posted December 17, 2022 Share Posted December 17, 2022 If anyone cares, I've gone from 17" on the 12 Gfs to 3" on the 00z. Fun week ahead. I'm in SE Indiana, btw. Link to comment Share on other sites More sharing options...
