FXHW60 PHFO 130118 AFDHFO
Area Forecast Discussion National Weather Service Honolulu HI 318 PM HST Thu Jun 12 2025
SYNOPSIS
Breezy trades become strong this weekend into next week delivering limited clouds and showers mainly to windward and mauka areas.
DISCUSSION
Closed mid-level low positioned west of the islands at press time is transitioning to a weak and sheared out low amplitude shortwave as it's partially absorbed back into mid-latitude westerlies. This low remains of little consequence other than the attendant subtropical jet which is gracing area skies with occasional cirrus. Near the surface, observed soundings indicate a very firm trade wind inversion anchored near 6kft at Lihue and Hilo, though slightly weaker in the vicinity of Kauai courtesy of closer proximity to the low. This has kept a kept a lid on overnight showers while the daytime diurnal max has maintained dry predominantly dry conditions each afternoon. Little change expected going forward as showers remain light and ridging north of the islands strengthens. This will only reinforce stable trade wind conditions as trades become strong this weekend into early next week. Given the strength of the inversion and strengthening background trades, it will be worth monitoring favored downslope areas for gusty wind potential as early as Friday, mainly in Maui County and the Big Island.
Shear-induced upper low development is anticipated over the islands this weekend which may diminish stability a bit, especially over the western end of the state, but the shallow boundary layer moisture field will likely be unable to capitalize leading to a rather uniform scattered coverage of light-intensity showers each night.
AVIATION
A stable, moderate to locally breezy trade wind flow will persist through Friday, followed by an increase in winds during the weekend. Periods of MVFR ceiling and visibility in SHRA will focused along windward slopes, and during the overnight and early morning hours AIRMET Sierra for mountain obscuration may be needed. VFR will dominate over most leeward areas, but sheltered terrain will experience isolated MVFR conditions each afternoon, especially on the Kona slopes of the Big Island. The stable trade wind flow will produce light turbulence below 7,000 feet, but these conditions should not require AIRMET Tango through Friday.
An upper-level low to the west may produce some light turbulence above FL300 into early Friday.
MARINE
High pressure far northeast of the islands will remain nearly stationary through the remainder of this week and bring moderate to locally strong trade winds. High pressure will then re-center north of the region this weekend and help to further strengthen trades. Thus, a Small Craft Advisory for the windier waters and channels around Maui County and the Big Island remains in effect through at least Sunday.
Surf along south facing shores will be tiny to small over the next several days. A small, long period, south swell originating from a fetch near New Zealand will build late this weekend and help to boost surf heights through early next week.
Rough and choppy surf is expected for east facing shores through the forecast period due to the moderate trades. Tiny seasonal surf is expected for North facing shores.
HFO WATCHES/WARNINGS/ADVISORIES
Small Craft Advisory until 6 PM HST Sunday for Maalaea Bay- Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.
