A strong surface high will be centered north of Hawaii through the 
end of the week near 35 degrees north, with breezy to windy 
easterly trade wind flow. The models agree that a col will likely 
develop within the subtropical ridge axis over the weekend as a 
frontal boundary approaches the far northwestern islands. The 
high then rebuilds north of the state by next Monday before moving
northeast by Tuesday, with good overall model agreement.

The typical trade wind enhanced showers can be expected most days,
with perhaps some heavier showers across the northwestern Islands
for the end of this week with a brief increase in precipitable
water values. There are no major rainfall events on the horizon
over the next week.
