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.
