Summary

The high pressure in the north of the state will keep moderate to temporarily breezy trade winds at the end of next week. Pretty dry and stable conditions are expected until early Sunday, with some light showers that are at times effective in windward and mauka areas. A more typical shower regime for trade winds should resume on Sunday afternoon and last until the end of next week, with showers favoring the windward and mauka areas, mainly at night and in the early hours of the morning, and an isolated shower from time to time reaching communities in the Slipstream.

discussion

There is currently a 1033 mb high high on the surface in the center about 1400 miles north-northeast of Honolulu and driving moderate trade winds over the island chain this morning. Infrared satellite imagery shows clear to partially cloudy skies in most areas, with a little more cloud cover over the windward stretches of Maui and the Big Island, where radar images show some showers moving ashore. Elsewhere, very little shower activity is noted. The main short-term concern revolves around the likelihood of rain in the next few days.
The high pressure will continue in the north-northeast of the state today before absorbing it into a new stronger high in the north of the islands from Sunday to Monday. That high will then settle south and closer to the state from Tuesday through the end of next week. Trade winds will prevail during the weekend with moderate to locally breezy levels. The trades could then ease slightly on Monday before rising to airy levels from Tuesday through the end of next week.
As for the remaining weather details, a fairly dry and stable trade wind pattern is expected by early Sunday. Some light showers are possible during this time, mainly in windward areas, as well as over the lee slopes of the Big Island in the afternoon and evening hours. A weak mean disturbance then appears to slide slowly west over the islands from Sunday afternoon to Tuesday. This feature will likely raise the inversion heights slightly and slightly increase the activity of trade wind showers. No major change in the general weather pattern is expected for the second half of next week as trade showers continue to be concentrated in the windward and mauka areas, especially at night and in the early morning hours, with an occasional shower spilling over the communities in the Lee reached.

aviation

A surface high north of the area is sustained locally strong easterly winds near the surface. The low-level current will carry clouds and showers over the eastern parts of the islands, especially at night and early in the morning. The afternoon warming will create clouds and showers over the southwest slopes of the Big Island and Maui. Riding at high altitude keeps the atmosphere dry and stable so that VFR conditions prevail. There are no AIRMETs in effect and none are expected.

marine

A near-surface high center well to the north of the area will support seasonally sustained trade winds that will be moderately to locally strong, likely requiring Small Craft Advisory for waters around Maui County and the Big Island for the foreseeable future.
A small NNW swell is expected today, after that very little NW swell is expected. Moderate SSW swell is expected through the weekend, and the latest buoy observations suggest the swell might be a little bigger than expected, but peak surf heights are currently expected to be below High Surf Advisory levels along the S-facing banks stay. More small swells from the S are expected early next week. Trade winds near and upstream of the islands will provide brief ENO wind waves that will result in near-seasonal surf along the east-facing coast.
