I've saw alot of em trend NW but very few if any trend SW once it starts the N jog. Hopefully bad data ingestion but I've never been skilled enough to argue with the Euro...
Ive saw literally every model out there show huge amounts of snow in the mountains 24hrs before the event, yet when NWS GSP meteorologist look at them and cut the totals 60-70%..
90% of the time they are right.
Lots to interpreting models other than just looking at them
