  1. when you increase the confluence, you also increase lift near it due to the convergence. so although there is less phasing, you'll still get very heavy precip dealing with a shortwave like that
  2. northern stream has a much more confluent orientation compared to 00z
  3. guidance is still screaming for the 24th as the Pacific trough retrogrades and the -NAO lessens
  4. here's why I like the 24th... the Pacific trough retros and you have a big amplification signal downstream as the block decays and confluence lessens. it's a recipe for a big storm
  5. lmao the GFS is very amped, it just has more confluence. its progressive bias is not on display here
  6. yeah I was not expecting it to really dig in like that. CMC did trend in that direction, just not as extreme
  7. pretty distinct trend to separate the two streams over the last two model cycles, increasing confluence later on
  8. pretty distinct trend to separate the two streams over the last two model cycles, increasing confluence later on
  9. pretty distinct trend to separate the two streams over the last two model cycles, increasing confluence later on
  10. just a note... the GFS is farther south because it has more confluence from the northern stream, not because it's less amplified. it's actually way more amped with the southern stream than the ECMWF so, although it's farther south, it doesn't seem to be due to its typical bias. for the record, I still think it's wrong, but it has a bit more validity this time since the differences between it and the other models is actually pretty small, and the northern stream can absolutely destructively interfere instead of phasing
  11. granted, it's farther south because it has more confluence from the northern stream, not because it's less amplified. it's actually way more amped with the southern stream than the ECMWF so, although it's farther south, it doesn't seem to be due to its typical bias. for the record, I still think it's wrong, but it has a bit more validity this time since the differences between it and the other models are actually pretty small, and the northern stream can absolutely destructively interfere instead of phasing
  12. like this is where it's at. really nice evolution here, and it makes sense PNA ridge spike, weakening block, and southern stream vort slips underneath the flow
  13. years like 2010 and 2016 had a strong Pacific trough and potent STJ like this one. seeing blue colors off the WC isn't some death knell if you have blocking and Alaskan ridging
