Detailed Forecast

Synopsis

The low pressure system north of the islands will weaken over the next few days. A weak ridge will build north of the region allowing light to moderate trade winds to return through Friday. Trade winds will diminish once again over the holiday weekend with more stable and drier trends lasting through Memorial Day.

Discussion

A low pressure system north of the Hawaiian Islands will weaken a bit today allowing subtle building of the subtropical ridge north of the state. This slight increase in the strength of the ridge will produce light to moderate trade winds across the region through Friday.
An upper level low northeast of Oahu will keep enough instability over the area to produce brief passing showers during this trade wind time period. A few thunderstorms may develop over the higher terrain on the Big Island on Thursday afternoon. Otherwise cloud and shower trends will tend to favor windward and mountain areas in the overnight to early morning hours through Friday. Trade wind speeds will remain light enough to keep lingering daytime sea breezes over terrain favored western slopes of most islands. Wind convergence between sea breezes and light trade winds will produce some afternoon shower bands over select leeward locations.
Another low pressure system and cold front will move slowly across the Central Pacific basin north of the region late Friday through Monday. This approaching system will break down the weak ridge north of the state producing another round of light and variable winds over the region. Local scale land and sea breezes will strengthen during this time period. A building upper level ridge will produce warmer temperatures with stable weather trends through the Memorial Day Weekend. Another great weekend for outside activities.

Aviation

Light, but gradually strengthening, background flow will favor persistence of weak land breezes and prevailing VFR through early this morning. Moderate trades today will nudge the pattern toward a more typical distribution of showers focused mainly over windward coasts and slopes. A modified sea breeze pattern will emerge over favored leeward and sheltered areas.
No AIRMETs are in effect.

Marine

E to SE winds will trend a little stronger today as a trough N of the islands gradually dissipates, while a surface ridge to the N strengthens slightly. The locally moderate E winds may briefly become fresh in the channels, with winds remaining below Small Craft Advisory speeds. Winds are expected to diminish over the weekend as the ridge is forced southward to near Kauai by a front passing N of the islands.
Surf will be below High Surf Advisory (HSA) levels along all shores for the foreseeable future, but a steady pulse of small to moderate swells are expected from both the S and NW. The S swells may push surf close to HSA-levels along S facing shores over the next couple of days, trending a little lower over the weekend. Surf along N facing shores will trend a little higher the next couple of days, with a potentially larger NW swell arriving on Memorial Day and persisting into next week.
See the Coastal Hazard Message (CFWHFO) for information regarding minor coastal flooding during the time of peak high tides the next couple of afternoons.
