discussion

High pressure in the north is maintained today with breezy trade winds, with the winds easing a bit tonight and Monday as the high shifts west. Early morning satellite imagery shows streaks of rainy low cloud moving on the windward slopes from Maui to Kauai. Expect rain to continue on the windward side, along with the occasional shower of rain before it becomes partially clear by noon. The Big Island can expect typical trade wind weather into the next week, with occasional rain over windward areas and a day pattern on the leeward side of mostly clear nights and mornings, which are mostly cloudy, with occasional showers in the afternoon and evening.
A static trade wind weather pattern will continue into the coming week with moderate to stormy easterly winds and showers mainly falling over the windward coasts and slopes. Occasional stains of moisture on the trades lead to increasing rainfall.

aviation

High pressures in the north of the state will propel breezy trade winds for the next few days, while a central ridge maintains stable conditions with an inversion between 5,000 and 7,000 ft. AIRMET Tango remains below 8,000 ft above and immediately southwest by northwest of the mountains for all islands and is likely to remain so through Monday.
Aside from afternoon clouds and a few showers on the Kona slopes of the Big Island later in the afternoon, MVFR conditions will be focused on the windward areas. There is currently no AIRMET Sierra for mountain darkening and the conditions for that remain borderline early this morning. Monitors all output requests.

marine

Strong high pressure far north of the area continues to generate fresh to strong trade winds over the area this morning. Trades will ease slightly tonight through the first half of next week but are likely to remain strong in the typically windy areas of Maui and the Big Island. The Small Craft Advisory (SCA) was scaled back a bit this morning as trade in parts of the marine area has eased slightly, with the SCA now covering the waters around Kauai and the typically windy waters around Maui and the Big Island until 6 p.m. tonight. The SCA will likely be scaled back later in the day to include only the typically windy waters around Maui and the Big Island, with this SCA likely to last through the middle of the week.
A new long south swell is only just beginning to arrive at NOAA buoys south of Hawaii at 3 a.m. and is expected to gradually fill in locally this afternoon and tonight. These waves will bring them to the south-facing banks for a longer period of time this week, well above normal surf. Surf will likely take place at High Surf Advisory Levels Monday through Wednesday, with the peak day expected to be Tuesday. The swell will then gradually decrease from Thursday to the next weekend. A number of small, short-term swells are expected in the northwest in the middle of the week, keeping the surf just above typical summer levels. Heavy east trade over and upstream of the islands will continue to create increased short-term surf along the east-facing coast through Monday. The surf on the east coast will gradually trend down and below the summer average from Tuesday through next week as the trade winds relax over and upstream of the state.
