Upper low currently just to the east of the Big Island will
continue to slowly move eastward over the next few days, but an
upper trough axis is forecast to linger over the region through
the weekend and early next week. Models/ensembles show this
evolution but differ on how quickly to build heights. A compromise
solution is preferred. At the surface, a frontal boundary will
approach the NW islands on Friday but weaken as high pressure
moves in behind it along 33N. This should bring in breezy
conditions to the islands. PW values are expected to rise slightly
ahead of the front or shear axis and then decrease after Monday.
Rainfall should be light to modest, favoring windward/terrain
areas most.
