...Wet pattern developing...

Guidance solutions reasonably agree to re-establish and initially
veer trades this week as high pressure bridges to the north and
settles to the northeast of the state. This pattern brings an
increasing chance to tap deeper tropical moisture to fuel
showers/thunderstorms as upper troughing works over the islands.
Moisture may linger over the Big Island this weekend, but there is
now a decent guidance signal to bring stabilizing upper ridging
over the state into next week.
