SnowGoose69 Posted September 19 Share Posted September 19 This feels like when all the models show a massive coastal storm at Day 7-8 and everyone assumes its 2024 the models cannot all be wrong on that, SOMETHING will happen and then we've seen often times it does not since 96-120 tends to be more of the magical range for that theory. Add in that everything has struggled to develop this year and you'd still need a perfect scenario where it misses the Yucatan here for this to be something close to what guidance is indicating. I think A storm happens but the odds something this perfect materializes is low 4 3 Link to comment Share on other sites More sharing options...

Windspeed Posted September 19 Share Posted September 19 Low background pressures and intense convective bursting throughout central America this afternoon. The broad surface trough slowly organizing and should resemble a CAG over the next 24-36 hours. At that point, we'll have to start focusing on the NW Caribbean for any potential vorticity that may spin off NE of the monsoonal surface flow.Heavy rains and flooding have already been an issue in Guatemala, Nicaragua, and Costa Rica today. 2 2 1 Link to comment Share on other sites More sharing options...
dbullsfan Posted September 19 Share Posted September 19 So this is either gonna be a major hurricane hitting Tampa or a Tropical Storm hitting Texas or somewhere in between. Got it . 2 Link to comment Share on other sites More sharing options...

bdgwx Posted September 19 Share Posted September 19 12z UKMET has a pretty large and weak circulation moving due north just east of the Yucatan at hour 168. Extrapolation is a skill I still struggle with, but it looks like it is going to miss the trough and loiter a bit after 168 at least according to the UKMET anyway. There might even be a bit of a Fujiwhara interaction with a closed low on the Pacific side. Link to comment Share on other sites More sharing options...

Amped Posted September 20 Share Posted September 20 A lot of difference in the handling of the pattern. Gfs and Ukmet digging a troff along the southern apps, other models, not so much. Cmc and ecmwf AI have a cutoff low over TX/OK Link to comment Share on other sites More sharing options...
StantonParkHoya Posted September 20 Share Posted September 20 GFS kind of looks convective feedbacky to me the way it jumps the low with the convection. Don’t know if that’s possible at that hour at that resolution but whatever. its only 1000 miles different from 18z CMC is in SW Arkansas at 222, GFS is off Cape of Maine.

Normandy Posted September 20 Share Posted September 20 GFS is a goddam mess. No consistency (and I’m not faulting the model it’s just output is chaotic which might be indicative of the pattern). Link to comment Share on other sites More sharing options...
GaWx Posted September 20 Share Posted September 20 0Z Euro: LLC forms eastern Bay of Campeche at 168 but moves and strengthens little through 240. At 240 it’s at 1002 mb with the entire Gulf having BN SLPs. Interestingly, a 2nd low (1004 mb) forms in the NE Gulf at the end. Link to comment Share on other sites More sharing options...

purduewx80 Posted September 20 Share Posted September 20 6 hours ago, CurlyHeadBarrett said: What’s making them change all of a sudden It appears that way when you focus on operational runs, but the ensembles have been showing two camps for days, with other solutions somewhere in between. The Euro ensembles have had the most support for a slower/more westward track. As usual it comes down to where and when a surface low consolidates. There is also a lot of work to do with the upper pattern near the Gulf Coast, which is highly variable due to energy potentially undercutting the Upper Midwest ridging next week. 6 2 1 Link to comment Share on other sites More sharing options...
purduewx80 Posted September 20 Share Posted September 20 Certainly seeing the beginning stages here, but it will probably take several more days for something to consolidate. Link to comment Share on other sites More sharing options...

Which one mogs (is better) for invests and disturbances that haven't formed yet? Operational or ensembles? 2 Link to comment Share on other sites More sharing options...
WxWatcher007 Posted September 20 Share Posted September 20 Ensembles. You treat the operational runs as extensions of ensembles at this stage imo—just one solution in the greater whole. It’s always a good idea before looking at the specific outcomes of these runs to take a step back and analyze the steering and development/intensification environment first. 6 Link to comment Share on other sites More sharing options...
