Advisory-level surf will remain possible along the east facing beaches due to the strong trade winds, beginning as early as Saturday evening. Elsewhere, no significant surf is anticipated through the weekend. Looking ahead through the upcoming week, the latest wave model guidance has begun to reflect a small to moderate south swell by the end of next week in response to the recent gale located east of New Zealand. Although later observations at the buoys farther south across the Pacific will need to be monitored over the coming days, this southerly source will likely support near advisory-level surf along the south facing shores by next Friday. The current advisory and gale warning will remain in place through the day Saturday. Although the winds will begin to ease Sunday through the upcoming week, the Small Craft Advisory will likely be extended, mostly for the windier marine areas from the Pailolo Channel to the waters south of the Big Island.

Weather Outlook for Saturday

Strong and gusty trade winds will affect the state through today, with a slight drop in winds expected for the rest of the holiday weekend. A dry and stable air mass will result in rather dry conditions with very little rainfall through today. The airmass will gradually moisten from the east tonight through the remainder of the holiday weekend, leading to increased showers that will periodically spread leeward on the smaller islands. A fairly wet moderate to breezy trade wind pattern will prevail during the early to middle part of next week, followed by lighter trade winds and somewhat drier conditions for the later part of the week.

Mainly dry and windy conditions prevail across the Aloha State on this early Saturday morning. Rain gauge and radar data show some light rainfall amounts over windward sections of Maui and the Big Island. The strong trade winds are being driven by surface high pressure centered about 1200 miles NNE of Oahu. Aloft, an upper level low is centered several hundred miles west of Kauai, and continues to bring areas of high-level cloudiness over the islands. A mid level ridge is located just to the northeast of the islands, and a very stable airmass is present over the state. The 12Z Lihue sounding shows a low/strong inversion based around 5k feet, with strong low-level winds ranging from 25 to 35 kt.

A few locations around the state have observed wind advisory criteria conditions of 30 mph sustained winds or 50 mph wind gusts thus far during this event. Most areas have seen sustained winds of 20-25 mph and peak gusts in the 40-45 mph range. The latest model guidance continues to indicate that the strongest winds are occurring now and will continue into this morning before slowly diminishing. Model soundings show low-level winds near 30 kt during this time, with the inversion remaining strong and lower than usual. This combination of factors will continue to produce conditions conducive for strong wind gusts over and downwind of island terrain. A wind advisory remains in place through 6 PM today for the entire state, and there is a small chance that the Haleakala summit will see high wind warning conditions. Otherwise, rather dry conditions will persist today. The above mentioned mid level ridge and unusually low inversion will keep low-level moisture minimal. A few showers may affect the windward Big Island and windward East Maui, but little to no rain is expected elsewhere.

Trade winds will ease somewhat tonight and Sunday, and shower activity is expected to return to more normal levels as the inversion rises and increased low-level moisture moves into the state from the east. Expect passing but more frequent showers over windward areas, with the breezy trade winds carrying some showers over leeward portions of the smaller islands at times.

A somewhat wet moderate to breezy trade wind pattern appears to be in store from Sunday night through at least Tuesday, as areas of increased low-level moisture move through the state, while forecast soundings show the inversion up between 8 and 10 thousand feet. Showers will remain most frequent over windward areas, but should be numerous and substantial enough so that some will be carried leeward in the trade wind flow. Somewhat drier and less breezy trade wind conditions may develop around midweek and continue through the later part of the week.

The high clouds that have been producing periods of interesting sky conditions during the past several days will thin over at least the eastern half of the state today as the upper level low to our west drifts further away and ridging noses in from the southeast. Thicker high clouds will likely return by Tuesday and continue through midweek as the upper trough to our west strengthens once again.
