Latest model guidance seems fairly agreeable that an upper level
ridge and mean surface high pressure should prevail for the next
week over/north of Hawaii. This will maintain brisk to strong
trade winds, focusing showers primarily over windward/mountain
locations. Winds should turn more easterly this weekend and
onward, with gradually increasing speeds through the week as the
high pressure to the north strengthens with time. Models do show
sheared shortwave energy/a weak upper low retrograding south of
the state during the weekend into next week before it gets
absorbed into energy west of Hawaii. Consensus shows precipitable
water values rising to around normal levels or so for a time
during the weekend/early next week due to this upper low. Moisture
may remain close to normal on average through next Thursday with
some fluctuations as drier/wetter pockets move along within the
trades.
