Models and ensembles are in very good agreement with the forecast
over the next seven days. Eastern Pacific surface high pressure
will extend a ridge axis across and beyond the islands for the
majority of the forecast. The high pressure is in response to
short wave ridging north of the islands and a more large scale
high over the tropical eastern Pacific. These two features will
gel by this weekend up and down the west coast of the lower 48.
Then by early next week, this ridging will yield to a rather
strong 588dm ridge to build in from the west.

Multiple fronts will attempt to approach from the northwest, as a
flurry of strong pacific short waves track west to east over the
pacific, but likely will not reach the state. Overall
precipitation chances will be low with some windward/trade showers
over the eastern portion of the Big Island and perhaps a few
showers reaching Kauai, especially with the front approaching late
this work week.
