WhiteoutWX Posted April 22, 2017 Share Posted April 22, 2017 12z GFS and 00z Euro now both showing Thursday/Saturday threat contained to southern/eastern OK or Arkansas. GFS drives a front into central Texas Wednesday and never quite fully recovers into OK by Thursday afternoon. The surface low is more of a surface trough extending across OK instead of a nice closed surface feature which is kind of what we just dealt with yesterday.

CGChaser Posted April 22, 2017 Share Posted April 22, 2017 Still a decent time for geographic adjustments to the threat. Theme is it is still there. Also, not sure Tuesday should be slept on. GFS/Euro convection in eastern OK/KS in a decent environment. Link to comment Share on other sites More sharing options...
andyhb Posted April 22, 2017 Share Posted April 22, 2017 12z CMC and UK go to town on Tues-Wed's system and leave nothing behind for Thursday-Saturday. Link to comment Share on other sites More sharing options...
Weatherdemon Posted April 22, 2017 Share Posted April 22, 2017 TSA and OUN saying severe but also calling for lot of rain. Seems like early discrete cells quickly forming into a line looking at the GFS convective precip view. SPC focused on Thurs/Fri, local offices more on Friday.

thewxmann Posted April 22, 2017 Share Posted April 22, 2017 That would really be shocking to be honest.How so? The CMC/UK were the first to sniff out the last NE snowstorm and the UK was the first to sniff out Matthew's turn towards the CONUS. It's a valid concern.Sent from my Nexus 6 using Tapatalk Link to comment Share on other sites More sharing options...
weatherextreme Posted April 22, 2017 Author Share Posted April 22, 2017 Latest from FWD regarding next Friday-weekend Friday and into the weekend does have the potential to be a bit more active in terms of weather as a trough should dig far south enough into the region to provide sufficient lift for precipitation. With adequate values of CAPE and favorable shear profiles, the stage could be set for another round of strong to severe thunderstorms across North and Central TX. Right now, details are a little unclear, but just about all modes of severe weather appear plausible. Link to comment Share on other sites More sharing options...

Sent from my Nexus 6 using Tapatalk Lol, I see you found your opening. It would be shocking because it is the lead wave and not nearly as strong the wave for Friday. Models often mistakenly over emphasize the lead wave only to come back as we get closer. You can site two instances neither of which are severe weather, I'll site the countless times where the lead wave is the moisture pump for a big event behind it.

I think that the CAA behind the lead wave could be overdone as well. Citing the fact that it isn't nearly as strong of a wave and that climatology for this time as a whole would suggest otherwise. In my experience, huge sweeping cold fronts that clear the plains of moisture are rare this time of year. Link to comment Share on other sites More sharing options...

brettjrob Posted April 22, 2017 Share Posted April 22, 2017 Have to say, the bias against any opinion falling even slightly on the pessimistic side of the fence once the hype train has left the station can get tiring. In this case, have we learned nothing from the past several years? We just went through monster late April troughs in 2014 and 2016 that looked Andover-esque in the medium range, then the threat either shifted east out of chase alley (2014) or simply busted (2016). Yet another extremely hyped trough that failed to deliver was April 25-26, 2009. This time of year in the Plains, big troughs are big gambles: they can lead to terrifying outbreaks when the stars align, but that isn't the norm. And oftentimes, when they fall, they fall hard. So anyway, yeah, this morning's runs are pretty depressing if you're specifically looking for an outbreak along and W of I-35. There's still plenty of time for it to move back toward earlier solutions, and it's not "over" by any means. In particular, if you're just talking about whether there will be a decent tornado event somewhere late next week, that's a pretty decent bet. I do understand we all have our personal perspectives and biases and they naturally get on each others' nerves this time of year, which is nothing new. This one just amuses me because I'm having flashbacks to some relatively similar situations in recent years where the naysayers generally were vindicated.

bjc0303 Posted April 22, 2017 Share Posted April 22, 2017 I'm gonna have to say I am disappointed in the last two ECMWF runs. I don't care much for tornado events east of i-35 in OK. Not over by any means, as there isn't great consistency at this point, but the fact it's trending the wrong way is concerning. Link to comment Share on other sites More sharing options...

I do not particularly care for anything east of I-35 as well. Terrain becomes a problem, its a jungle, and radar coverage generally becomes spottier. There's also just something majestic about supercells/tornadoes in the classic west-of-I35 corridor. Changes between the 18z/00z GFS of yesterday and the 06z/12z runs today for Thursday's setup were mounimental, and changes in the 12Z euro yesterday compared to the 00z euro for Friday and Thursday were also significant. Lots of variability, so hopefully models will shift back tonight and tomorrow. Still 4 to 6 runs outside of the higher-level skill of any of the models.

bjc0303 Posted April 22, 2017 Share Posted April 22, 2017 Definitely quite a ways out and I'm sure the GFS will do its best to put on a show again with the next few runs, but until the euro jumps back on board, I remain pessimistic. After all odds for truly spectacular events actually panning out are never in our favor. If they were the Plains would be uninhabitable. Now I will say: subtle changes in flow aloft can change this in a hurry. I don't know how much I buy such a cold frontal surge given the anticipated evolution of the jet. Think it is more likely these waves evolve northeast rather than amplifying and diving a cold front into TX. It is far from over and definitely still holds incredible potential, but this is very clearly farrrrr from a done deal. Link to comment Share on other sites More sharing options...

If you are looking at it specifically for chasing west of I35 only then yeah that could be ruined with this. However, I am looking at this from the meteorology side of things where there even with the bad model runs there is still a great potential of an outbreak in the southern Plains or MS valley.

A lot of us are chasers and have made plans for this storm system. It may not be a big deal for those watching at home (and to be fair, I used to be one of those guys) but it is for the rest of us. So the model shifts today are significant and noteworthy and not ignorable.Sent from my Nexus 6 using Tapatalk Link to comment Share on other sites More sharing options...
