Faster GFS trends with the front crossing the islands Fri-Sat
yield improved model agreement for the forecast period.  During
the next couple days winds should range between southeasterly and
southwesterly, with the state between the southwestern periphery
of eastern Pacific high pressure and flow ahead of the approaching
front.  At times winds may be sufficiently light to allow for sea
breeze shower activity.  The Fri-Sat front should bring a period
of more organized showers but still with mostly light-moderate
amounts given precipitable water values likely not exceeding
1-1.25 inches or so.  Expect trailing high pressure to support
northeasterly trades through at least Tue.  Another front
approaching the region on Wed may disrupt trades at that time. 
Windward focused rainfall should remain fairly light early next
week with PWATS likely dropping below an inch for a period of time
especially to the northwest of the Big Island.
