Planetary Longwaves Looking Good

I'm liking how the planetary longwaves (typically five around the northern hemisphere) are setting up this next week. One of the longwave troughs looks like it will be parked off the U.S. West Coast - a favorable place for eventually bringing rain to desiccated California. In fact, that trough is the ONLY thing that will bring substantial rain to the Golden State! The trick will be keeping that trough in that place long enough to matter.
