Summary

A high pressure ridge will persist north of the Hawaiian Islands until next week, generating moderate to breezy trade winds across the state. Stable air conditions will hold for drier weather today with only brief rain showers this morning. A convergent band of clouds will drift north of the state over Niihau Kauai, Oahu and Molokai on Thursday and Friday; Improving shower activity over these western islands. This trade wind weather pattern will last until the middle of next week, with winds picking up to airy levels this weekend. Short showers favor the windward and mountainous areas, especially at night until the early hours of the morning.

discussion

The large weather pattern shows a high pressure system north of the islands that creates stable trade winds throughout the region. A rapidly dissolving frontal border lingers north of Kauai and Oahu. Two upper lows are located east and west of the island chain, with a stable ridge firmly anchored over the Hawaii region. In the short-term forecast, these weather characteristics will generate stable moderate to locally airy trade winds today. It is expected that increasing precipitation trends for the western islands will move with the convergent cloud band on Thursday and Friday.
On Thursday and Friday, the weather pattern will change for the western half of the state. A convergent band of clouds connected to the remnants of the ancient frontal system will drift into the western islands of Niihau, Kauai, Oahu, and Molokai; Improving the activity of trade wind showers. Short haul models continue to show this band of cloud reaching the west side of Maui County with some increased showers on Thursday, and shower coverage has been increased over Molokai to accommodate changing conditions. Windward and mountain slopes will see the higher amounts of rainfall with less rainfall coverage over leeward locations. Eastern trade winds will slowly drive these clouds west back to Niihau and Kauai on Friday, with drying tendencies for Molokai and Oahu. The cloud band clears on Friday night west of Kauai.
Saturday to Tuesday … Moderate to stormy trade winds continue with weak high valleys that pull across the chain of islands. Expect short, temporary showers, which mainly affect the windward and mountainous regions at night until the early hours of the morning.

aviation

A moderate trade wind flow will continue for the next few days. The satellite shows more clouds immediately upstream of Maui County and the Big Island than the rest of the islands. The trade winds carry the clouds and showers to the windward slopes, with Big Island seeing more clouds than most of the smaller islands, followed by Maui. VFR conditions will prevail with some isolated areas of MVFR. Although the wind is tending upwards, no problems with mechanical turbulence are to be expected for the next few hours. An AIRMET for turbulence is more than likely today, as the wind is likely to tend a little more upwards.

marine

A front that washes out across the far northerly offshore waters while high pressure builds up again from north to northeast of the islands will allow the return of moderate trade winds throughout the week. In the next few days, trade will be fresher and stronger locally across Maui County and the Big Island. The Small Craft Advisory has been extended to Thursday afternoon to take account of these windier canals and bays.
The current 4 to 5 foot, 10 to 14 second northwest swell of 320-330 degrees moving around the islands culminates in early June with morning surf on the north and west coasts above normal levels. That swell will fall by the end of the week, with near-flat surf expected on the north and west coasts by Friday. Very small, prolonged southerly swells will remain slightly below normal surf along southerly exposures throughout the day. The surf on the south coast can pick up slightly towards the end of the week or this weekend when some overlapping slightly larger, long-lasting south-southwest swells arrive. The east coast chop / surf could also get a whiff as trade above and upstream of the state picks up at more sustained new magnitudes later this week and into the next week.

HFO watches / warnings / notices

Small Craft Advisory until Thursday 6:00 p.m. HST for Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters.
