summary
The strong trade winds will gradually ease today, Thursday and Friday, leading to the appearance of low clouds and rain showers heading towards the windward slopes and coasts, especially during the night and morning. Some light rain will also spread downwind at times with strong trades. The winds will become light and shift to the south on Saturday as the front approaches. The front is expected to arrive on Sunday, which may lead to increased rain in leeward areas. Light winds will blow next week.
discussion
Strong high pressure from the north of the islands supports strong and relatively cool trade wind flows into the ENE this morning. A wind advisory remains posted for areas in Maui and Hawaii counties where winds are more accelerating due to terrain. Although the island’s atmosphere is quite stable with a strong downward inversion centered around 8,000 feet and below normal PWAT near 1″, the steeply low break rates below the inversion allow highly efficient warm rain processes to drive the formation of quite a few From showering. Radar shows numerous small scattered showers moving over the islands while satellite images show scattered low open-celled clouds (also known as showers) approaching the islands from ENE.
The high will weaken as it approaches the islands over the next couple of days, resulting in a slow decrease in trade wind speeds. Model guidance suggests little overall change in the incoming low-level moisture field, so precipitation will favor leeward areas through the night and morning into Friday, with less rain spreading downwind with easier circulation.
Late Friday, a weak high will move northeast in response to a strong circulation forming northwest of the region. Winds will briefly become light southwest on Saturday as an associated front approaches from the northwest. The front is not expected to be particularly strong, but will likely bring some rain as it moves southeast of the ridge Sunday/Monday. Although some cold advection in the form of moderate northeasterly winds may occur immediately after the front passes, winds are expected to diminish quickly afterward as the front dissipates over or just east of the islands early next week.
airline
Strong trading will continue locally during the forecast period. Low level moisture will bring scattered showers on the leeward sides of all islands this morning, then coverage will decrease this afternoon. Periods of MVFR and vision ceilings likely accompany this activity. In addition, isolation may push terrain and affect leeward locations.
AIRMET SIERRA remains in effect to the north across the eastern portions of the Big Island blocking the Rhythm Mountains above 3,000 feet.
AIRMET TANGO remains in effect for moderate low-level disturbance over the mountains and downwind of all islands due to locally strong trade.
Navy
Strong trading will continue from the northeast to the east with storms approaching over the channels and windier waters around Maui and the Big Island today as strong high pressure continues to the north. These winds combined with a large area of strong to gusty northeasterly winds centered in the state between this high and low pressure in the extreme northeast of the region supports rough seas with highs hovering above the advisory level for small craft over open waters through Thursday.
Guidance shows the beginning of the gradient cooling off Thursday into Friday as high pressure north of the region settles southward and weakens, which will cause local winds to return to their fresh to locally strong range. Over the weekend, the progressive pattern will continue over the North Pacific Ocean as low pressure develops quickly northwest of the state on Friday, then rises northeastward as it passes to the north about 1,000 nautical miles. The front associated with this feature will approach and likely reach the western edge of the state by the end of the weekend. If this develops as expected, winds will become moderate south to southwesterly as the front approaches.
Waves along exposed north- and east-facing beaches will remain rough into the second half of the week due to a combination of local wind-generated seas and northeasterly ground waves from the aforementioned upstream. Highs will hover around the high surf advisory standards for east-facing beaches through Thursday. A strengthening swell coming from the same direction (050 degrees) on Friday may be enough to support the return of waves at the advisory level for eastern exposures. A downward trend is expected over the weekend as winds shift from the south.
Surf will rise along north- and west-facing beaches over the weekend as a small, long-lasting swell arrives from the north-northwest and moves through. A more significant event is possible Sunday night into early next week due to a large area of northerly storms expected to develop near the back side of the rapidly developing low passing about 1,000 nautical miles to the north this weekend. Highs with these nearby northern sources typically come much greater than expected, which could trigger a surf warning level warning early next week.
Surfing along south-facing beaches will trend higher over the weekend as a long-lasting southerly swell arrives.
