Summary

The low pressure system north of the islands will weaken over the next few days. A weak ridge will form north of the region, allowing light to moderate trade winds to return by Friday. Trade winds will decrease again on the holiday weekend with more stable and drier trends until Memorial Day.

discussion

A low pressure system north of the Hawaiian Islands is becoming somewhat weaker today, which enables a subtropical structure of the subtropical ridge north of the state. This slight increase in the strength of the back will generate light to moderate trade winds across the region through Friday.
An upper plain northeast of Oahu is maintained over the area enough instability to produce brief transient showers during this trade wind season. Some thunderstorms may occur over the higher ground on the Big Island on Thursday afternoon. Otherwise, cloud and shower trends will tend to favor windward and mountainous areas during the night until the early hours of the morning until Friday. Trade wind speeds remain slow enough to keep sea breezes over the daytime terrain that favors the western slopes of most of the islands. The wind convergence between ocean breezes and light trade winds will create some bands of afternoon shower over selected leeward locations.
Another low pressure system and a cold front will slowly move across the Central Pacific Basin north of the region from Friday to Monday. This approaching system will break the weak ridge north of the state and create another round of light and variable winds over the region. The local land and sea breezes will increase during this time. A ridge of buildings on the upper level will produce warmer temperatures with stable weather trends during Memorial Day weekend. Another great weekend for outdoor activities.

aviation

A slight but gradually increasing background current favors the persistence of weak land winds and the prevailing VFR until this morning. Moderate trades today will steer the pattern towards a more typical distribution of showers, mainly focused on windward coasts and slopes. The pattern of the sea breeze changes over preferred leeward and protected areas.
There are no AIRMETs in force.

marine

The winds from E to SE will tend to be somewhat stronger today, as a trough N of the islands gradually dissolves, while a surface ridge to N is slightly reinforced. The locally moderate e-winds can briefly get fresh in the canals, with the winds remaining below the recommended speeds for small boats. Winds are expected to ease over the weekend as the ridge is forced southward to near Kauai by a front running north of the islands.
The surf will be below the High Surf Advisory (HSA) level on all banks for the foreseeable future, but a steady pulse of small to moderate swells is expected from both S and NW. The swells can drive the surf on the S-oriented banks close to HSA levels for the next few days and tend to be slightly lower on the weekend. Surfing along the north-facing coastlines will tend to be a bit higher for the next few days, with a potentially larger NW wave arriving on Memorial Day and lasting into next week.
