The ongoing Kona low over the northwestern Islands that has been
making weather headlines for Hawaii will continue weakening
through the weekend, with a col remaining in the subtropical ridge
axis in its wake north of the state through Monday.  The ensemble
means indicate the subtropical high will build in between 30-35
degrees north by mid-week, and this the high will move east as a
storm system near 40 degrees north approaches with a trailing cold
front reaching the far northwestern Islands by late week, with the
EC mean slightly southeast with the front compared to the GEFS
mean by that time.

Trade winds will generally be more variable going through the
weekend with the col north of the state, but winds should become
stronger out of the east to northeast by Tuesday and Wednesday
with the surface high passing north of the state.  Some veering of
the flow to the southeast is likely going into the end of the week
with the frontal boundary approaching from the northwest. 
Rainfall in the wake of the Kona low should return to the favored
upslope areas with the deepest moisture remaining well to the
south.
