  1. 18z GFS ticked north, and slightly drier in only some areas. .
  2. The block/confluence hasn’t really changed in a negative way. The wave ending up further northwest in the Plains and peaking out that way is the bigger issue now. .
  3. 18z NAM bumped north. And the least surprising news of the day, it’s drier once again.
  4. That will be a question for @RCNYILWX, as LOT would handle that decision.
  5. next time know what you're talking about first, before trying to claim an lol victory. see above.
  6. channeling your inner angrysummons here. yes, everyone did know the storm was going to shear apart with eastward extent. i'm not sure there is anyone here that didn't believe that. however, the trend for the storm to end up further northwest in the plains due to additional ridging (in part) is not something that was originally modeled...and is part of why it is shearing out faster as it heads east. please share your crystal ball next time.
  7. One thing that we have seen change over time is for the storm system to end up further northwest in the Plains, as it ejects out and gets caught in a bit of ridge that extends back up into the Rockies and BC/Alberta. This allows the storm system to peak sooner while out west, before hitting the wall and quickly shearing off to the east.
  8. That has been a large part of it, especially with how much the confluence over the Lakes/Northeast has been changing with time. There have also been some changes with the main southern wave with how far north/south it ejects out, as well as changes with ridging ahead of it. Another thing to watch, is the next trough coming into the West Coast, as that is actually somewhat acting as a kicker for our ejecting southern wave.
