The subtropical high centered near 35 degrees north is forecast to
remain nearly anchored in place north of Hawaii through early next
week, and the inverted surface trough currently near the far
northwestern Islands is expected to continue drifting farther away
from the state going into the weekend and beyond.  Looking ahead
to the middle of next week, the ensemble means agree that a col in
the subtropical ridge develops in response to a trailing surface
trough/front from a strong low pressure system over the southern
Gulf of Alaska.  This will likely persist going through next
Friday. 

Mainly easterly trade wind flow can be expected through Tuesday as
the pressure gradient remains in place, but a return to lighter
and perhaps more variable flow is likely by Wednesday in response
to the col developing.  Besides the normal locations for trade
wind enhanced showers, no major areas of organized heavy rainfall
appear likely over the next seven days.
