Meteorologist ClicheVortex2014 Posted February 17, 2023 Meteorologist Share Posted February 17, 2023 (edited) A lot of uncertainty about this next system. A big longwave trough dips into the western US, but severe potential could kick off as early as Wednesday. GFS has a pretty freaking ridiculous severe setup that reminds me a bit of Easter Sunday 2020. I don't buy it at this range, seems too crazy. Euro is more realistic but I think underdone a bit. Regardless, a large warm sector will be present ahead of a big ass western trough, so chances are some storms will happen. The question is the magnitude of the storms. Comparison between GFS and Euro. GFS digs that shortwave way down into the warm sector. I don't think it's very realistic but we'll see. A small dose of the absolute clown show that the GFS is putting on. Ridiculous hodograph, moderately unstable. Not a good combination. Area average sounding for west-central MS Point-and-click for just west of the above using Euro. Again, ridiculous shear but much different thermo profile. This profile would be too capped/dry for storms, but as shown above, there's still a big trough to the west. So that just creates an issue for the 3 days afterward. I think the most reasonable solution is between the two. I'm afraid that we'll end up with a more GFS-like thermo profile without the shear weakening too much. I don't trust Euro that much nowadays.

Iceresistance Posted February 18, 2023 Share Posted February 18, 2023 For Wednesday, do you think that it will kick off in Central and Eastern Oklahoma? Link to comment Share on other sites More sharing options...

Depends on where the dryline sets up. Euro and GFS both initiate convection there but early in the day and probably just thunderstorms. Plenty of time for things to change, but what I don't think is going to change is that the worst of the storms will be east of there.

And so would the Southeast as it could be a repeat of April 27th, 2011 and Easter 2020 all over again in terms of setup! Link to comment Share on other sites More sharing options...

On the other hand, most of the tornadoes from Easter 2020 were embedded within a squall... whether it was mesovortices or embedded supercells. But yeah, that was a prolific tornado day because of extreme shear and moderate instability. Both days were historic for a reason, though of different magnitudes of historic. I wouldn't expect another Easter 2020 to happen for a while. Overall though I agree, I wouldn't want to see this GFS-like setup any time of the year, much less in April. What concerns me with this setup is the warm sector.... unseasonably broad and moist. Not like it's a mystery how... very obvious that several weak systems help draw moisture north before that beast of a low ejects. Still a pretty far way out so as of right now, a few things I can see help bust this event: dry air/capping/weak instability holds on (e.g., Euro), messy storm mode, or one of the weak systems prior to the big one actually pushes a cold front to the Gulf.

Meteorologist ClicheVortex2014 Posted February 18, 2023 Author Meteorologist Share Posted February 18, 2023 This system is no longer in fantasy range, despite what one would expect when you see a setup like this in February Going out to Wednesday, we have this system producing precip literally from coast to coast 2 Link to comment Share on other sites More sharing options...
Meteorologist ClicheVortex2014 Posted February 19, 2023 Author Meteorologist Share Posted February 19, 2023 (edited) Thankfully GFS is trending toward a less favorable thermo profile for Wednesday. Weaker mid-level lapse rates. Shear is still extreme so it won't take much instability to get some severe weather.

Meteorologist ClicheVortex2014 Posted February 19, 2023 Author Meteorologist Share Posted February 19, 2023 (edited) Already got gusts in the 40s here today... windier tomorrow, Tuesday even windier, and Wednesday the windiest. There's new lee cyclogenesis literally every day until Wednesday. No wonder there's so much moisture to the east.

Just when I thought I was starting to understand how to forecast winds here... ugh. Record max low for tonight is 45 degrees... tonights forecast low is 49. Still 55 degrees right now. With the winds overachieving tonight, I have a feeling we won't get out of the 50s 2 Link to comment Share on other sites More sharing options...
ElectricStorm Posted February 20, 2023 Share Posted February 20, 2023 Definitely trending much less impressive now, and SPC has downgraded to marginal so not really expecting anything major. For my area though this could end up being a decent rain event so hopefully we can get in on some of that. Might need to watch 2/26-27 for the next potential severe weather setup. 1 Link to comment Share on other sites More sharing options...

Was pleasantly surprised to see the 00z GFS had a possible severe event to the eastern Texas Panhandle Sunday. Not surprised to see it go away already.

ak9971 Posted February 22, 2023 Share Posted February 22, 2023 Well, based on current warning and the watch, looks like they nailed the location of the slight risk today. Link to comment Share on other sites More sharing options...
Neoncyclone Posted February 22, 2023 Share Posted February 22, 2023 73 degrees, windy, with a tornado watch. If I didn't know any better I'd think it was April. Don't expect much in the way of severe weather as my location has pretty weak dewpoints and some veering winds. Link to comment Share on other sites More sharing options...
