The models and ensemble means continue to agree upon a persistent
trade wind pattern with mostly windward/mountain showers through
the period, as high pressure initially north of the state soon
settles into position over the east-central Pacific. Trades should
be moderate to occasionally brisk into early next week and then
may weaken somewhat by Wednesday-Thursday as an upper weakness/low
moves in from the east and shifts north of the state. This may
provide a little more potential for sea breeze influence if the
background flow weakens sufficiently. Overall though, rainfall
amounts should be fairly light as guidance maintains below normal
precipitable water values through most of the period. Some uptick
in moisture is possible by later next week, although at this time
the guidance suggests the weakness should slide to the north of
Hawaii as riding holds over the islands themselves.
