SYNOPSIS
East southeast winds continue through Thursday supporting drier weather from Oahu eastward while Kauai experiences periods of enhanced showers today and Monday. A return to a breezy trade wind pattern is in store for the end of the week.
DISCUSSION
The Hawaiian islands remain on the poleward side of the Pacific jet through the week while a somewhat progressive mid-latitude pattern produces mean troughing centered around 170W longitude.
Consequently, low pressure and a weak background gradient prevail over the western end of the state while breezy ESE persist over the eastern islands as high pressure settles along the west coast of the CONUS.
Drier air has filtered in today as evidenced by nearly cloud free skies over the islands early this morning. However, some moisture continues wrapping around the Big Island and may bring a few afternoon showers to Kauai and vicinity this afternoon. PoPs remain appropriately higher there while drier and sunnier conditions prevail elsewhere. This may be the case on Monday afternoon as well as the weak gradient gives rise to expanding sea breezes over Kauai coincident with a mid-level shortwave grazing the islands from the north. This should further reduce stability over Kauai and may result in a couple locally heavy showers over interior or leeward zones during Monday afternoon. The high res guidance offers a similar picture which increases forecast confidence. Any afternoon convection will diminish with the loss of diurnal heating Monday evening. The pattern will remain generally stagnant through at least Tuesday.
Wednesday into Thursday will represent a transition period back to a typical easterly trade wind pattern. Global model consensus indicates that a low will close off over or near the islands immediately south of expansive ridging building over the Central Pacific. This will set the stage for a breezy and weakly stable easterly trade wind pattern settling in by week's end.
AVIATION
Moisture riding in on light to moderate ESE trades will continue to provide a steady supply of showers to E and SE facing areas of the islands, especially Maui and the Big Island. Tempo MVFR conditions expected within heavier showers. With a SE component to the winds, showers will occasionally be steered across leeward areas as well.
Drier air will move in from the E later today, allowing conditions to improve across most of the state, but moisture to linger across Kauai. With the lighter ESE flow and decreased cloud cover, afternoon sea breeze activity is expected across wind-sheltered areas, with some inland/leeward cloud buildups and a few light showers possible.
AIRMET Sierra for mountain obscuration is in effect for portions of the Big Island and Molokai through Kauai. This AIRMET will likely be needed through the morning hours before conditions begin to improve.
MARINE
Surface high pressure far northeast of Hawaii and an approaching front to the northwest will drive breezy east southeast winds today, especially across all windward waters and through the channels surrounding Maui County and the Big Island. Through early this week, the aforementioned surface high will drift eastward and allow flow to weaken. By mid-week, high pressure will rebuild to the north and allow easterly flow to strengthen again.
A Small Craft Advisory for winds will remain in effect for most waters and channels surrounding Big Island, Maui, and Molokai through Monday morning, likely will be dropped as winds weaken.
Surf heights will remain below advisory thresholds for all shores through the forecast period. A small northwest, medium-period swell will persist through mid-week with small surf expected.
Breezy east or east southeasterly flow will produce choppy surf along east facing shores through tonight, then decrease as winds begin to taper off early next week. Small, short-period southeast, and small medium-period south swell will continue into mid-next week. Surf heights along the south facing shores should remain near or slightly below seasonal norms.
HFO WATCHES/WARNINGS/ADVISORIES
Small Craft Advisory until 6 AM HST Monday for Maui County Windward Waters-Pailolo Channel-Alenuihaha Channel-Big Island Windward Waters-Big Island Leeward Waters.
