HONOLULU (KHON2) – A 1035mb high northwest of the islands combined with inversion heights around 6 kft this afternoon have caused winds to reach the Wind Advisory threshold in portions of Maui Countya nd the Big Island this morning into this afternoon.
The advisory remains in good shape and remains in effect through 10pm HST this evening.
The high will weaken slightly tonight and Monday, but the gradient locally will remain quite strong keeping breezy trades in place.
A front passing by to the north of the state and a weak trough moving in from the east should weaken the gradient Tuesday into Wednesday, easing the trades to moderate levels.
A new strong high building north of the islands Thursday into next weekend, could bring a return of breezy trades to the state.
Moisture associated with an old front will remain in close proximity to Kauai through Monday keeping shower coverage the highest here, while drier trade wind weather prevails over the remainder of the state.
The frontal remnants will push southward Monday night and Tuesday bringing an increase in shower coverage from Oahu to the Big Island with little change in the weather across Kauai.
The band of enhanced moisture will then meander over the islands Tuesday night through Thursday, bringing periods of showery weather mainly to windward areas, although the trades will allow some showers to reach leeward communities at times as well, mainly overnight and during the early morning hours.
The deepest moisture then lifts northward Friday and Saturday, allowing a more uniform distribution of showers to return to the island chain.
