Latest model guidance seems fairly agreeable that an upper level
ridge and 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. Expect winds to be from the northeast late this week
and then turn more easterly from the weekend onward, with greatest
strength across the state later next week when high pressure to
the north should be the strongest. Models do show sheared
shortwave energy forming a weak upper low that should retrograde
south of the state during the weekend into next week. Consensus
shows precipitable water values below climatology late this week
and then perhaps rising to around normal levels or so for a time
during the weekend/early next week due to the 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.
