  1. the RGEM is actually really similar to the AI models... has the main precip with the PVA ahead of the main vort
  2. the Pacific trough pumps the PNA... that's part of the reason why it usually torches after big storms as the jet overextends
  3. yup. first, moisture pushing into a cold dome and then a shot at a retrograding block to end the month. can't ask for more at this range
  4. lol it only nails it if the solution is crappy. we've seen it amp up and do interesting things only to fall flat on its face
  5. it’s a bit more consolidated and precip is a bit farther west but still, not great
  6. notice how the vort is less involved in the broader trough… way more legit PVA here compared to the previous run as it pivots
  7. yeah, in between. nice to see with the AI looking good and the CMC likely coming in amped
  8. yeah, vort was looking more SW which is what the GFS did, but the lead wave dampened it. still like seeing that shift with the vort
  9. GFS looks quite a bit more consolidated
  10. it’s an average, you’re going to have members with the gradient south of the mean. not all that surprising
  11. hopefully we can eke something out before the 20th... the pattern looks to open up after the 22nd as more moisture gets involved and cold becomes more entrenched
  12. yeah, the 22-24th is a solid timeframe with established cold air, low heights over SE Canada, and some -NAO/-EPO. can see how you'd get something ejecting out of the west into cold air
  13. when you're forecasting past a week out, using ensembles and focusing on the broader pattern to point out timeframes of interest is generally the way to go. this will be taught in every forecasting classroom on the planet. now that we're a few days later on, we can see that there are two distinct waves rather than a single trough (which, by the way, some OP runs had) this is the way long range forecasting is... the data change sometimes. it doesn't make the process any less valid
