Look at 12z Precipitable water charts for the storm Approaching California
26th the system is weak and south of the feature in the gulf of Alaska. There is no connection the area around Hawaii, where PWS are below normal
following day ( yesterday) pws way below normal storm starting to take shape west of US coast
this morning
west of California still no connection to Hawaii. System origin from the westnorthwest
So we are now growing pineapples in the gulf of Alaska. The reason PWS increase off California was due to the deepening well to the north, not this pulling moisture out of places where Pineapples grow. There are not even any isobars that make it that far south
