summary
Mild trade winds will continue over the next few days, with light to locally windy trading returning early next week. Dry, stable air mass across the region will help limit windward and moka showers over most islands today. A weak disturbance will increase cloud and shower activity tonight into Saturday, with another weak disturbance moving across the islands next Tuesday. Neither disturbance is expected to bring significant rainfall, but should bring some beneficial rainfall to the windward and Mauka areas.
discuss
A ridge of high pressure in the far north of the state will maintain moderate trade winds over the next few days. Meanwhile, radar and satellite imagery continue to show brief showers moving into the windward areas of Maui, Molokai and Oahu early this morning under partly cloudy skies. Overall, today is expected to be sunny with light showers in the windward and Mauka areas and mostly dry on the leeward side.
HFO's latest 12Z surface analysis shows a weak trough about 225 miles east of Big Island. Guides continue to show that this trough will move across the state tonight into Saturday, causing an increase in windward and moka showers, especially on Maui and the Big Island. This morning, the latest CIMSS MIMIC layer PWAT shows a moisture mass about 1.6 inches east of the state, with a simulated PWAT of about 1.7 inches as the trough moves a few inches toward the Big Island. A period of moderate showers is possible on the Windward Big Island and eastern Maui, with 1 to 2 inches of rain possible along the windward slopes of the Big Island on Saturday. Overall, only showers are expected and should not cause flooding problems.
Showers will generally increase over the western half of the state late Saturday into Sunday, with scattered showers in windward areas. Cloud cover will increase in leeward areas, along with some showers. The weather will return to dry conditions Sunday night, with trading expected to become breezy on Monday. A light to locally windy trade will continue for much of the coming week as high pressure strengthens northeast of the state.
Another riot is expected to sweep across the state on Tuesday, with model PWAT thickness about 1.8 inches. This system will bring more widespread clouds and showers to the windward and mauka areas of all islands. As trade strengthens, some of these showers are expected to spill over to leeward areas at times. More typical trade wind conditions are expected to return following the disruption, with strong trading continuing into next weekend.
aviation
Trading will continue with mild to locally breezy conditions throughout the rest of the week and into the weekend. SHRA and low cigar will favor the windward and mauka areas and may bring about short-lived MVFR. Otherwise, VFR shall prevail.
No AIRMET is currently in effect.
ocean
A high pressure system and weak trough north of the Hawaiian Islands will allow moderate easterly trade winds to blow through the area into Sunday morning. Beginning Sunday afternoon, trade winds will begin to strengthen into locally strong ranges as the hot center currently located in the northwestern part of the state drifts eastward and intensifies. Trade wind speeds will be sufficient to support small craft advisory conditions in windy waters and channels near Maui and the Big Island starting Sunday night and into much of next week.
Today, swells will rise slightly towards the south facing coast and will drop to below average. The background south swell pulse of energy is expected to continue while waves remain below average. Slightly rough seas are expected along the east coast over the next few days as trade winds persist. The East Coast surf is getting rougher with the return of strong local trade early next week.
King tides peaked this weekend, with local tide gauges showing water levels already above guidance. Water levels are currently at least 1 foot above the mean high water (MHHW) threshold in Hilo, Kahului and Honolulu and are approaching the 1 foot threshold in Lihue. Therefore, a Coastal Flood Statement remains in effect throughout the weekend.
