Phasing will kick it out faster, at the same time, also tends to provide a little more colder air. Of course now Waco is cursed.

I have a hard time believing a barely positive PNA is going to be able to drive Arctic air away from Texas. Feel like we go through this with every Arctic front these days.

Remember, we’re in the medium range where the models lose the cold. Happens every time.

Pretty good agreement between the GFS and CMC for hour 180, even though it will probably change in the next run. LOL

With all due respect it doesn’t happen every time, if seen many occasions in situations like this where the models slowly warm up run by run, as it gets in better range.
