Summary

The good news is that the ridge will break down with onshore flow beginning in the PNW as early as Sunday. There is still model uncertainty on the strength of the 2 systems next week. The initial cold front due in the PNW late Sunday moves into the Rockies by Monday/Tuesday. The systems might weaken over the Rockies with low-end water totals. The wave late next week is colder and wetter.
