Pretty much what TonyC said... The lack of details on the pattern change is because first of course, it's still about a week away... and second, models keep swinging rather wildly on how the storm track sets up, thanks largely to the departing high pressure ridge.
Latest models (today) generally have the high still lingering over the northern Plains to the Great Lakes/NE through much of next week, which might make incoming storms off the PNW drop south and down into CA before moving inland (maybe missing much of the PNW).. Toward the following weekend, systems might start coming in more directly to the PNW, and then points SE. Of course, that might change 10 times before next week.
After a long stagnant pattern, this is pretty typical for models to struggle on the details, especially a week + out.
Btw, 72º in Bend today (previous record was 67º)... fricken unbelievable. We went ahead cancelled our Bachelor trip a few days ago (for next week). While we may get some snow later in the week, it's going to fall on very little remaining base.
Brundage today... lots of little ice balls (chicken heads)? today, thanks to the latest freeze thaw cycle (and grooming in between the thaw and freeze).
