Detailed Forecast

Synopsis

Light winds and mostly dry weather will continue into next week. Expect clear skies at night with afternoon and early evening interior clouds and scant showers. A weak front expected to stall and dissipate over the area this weekend may bring a subtle increase in clouds and showers to Kauai and Oahu on Saturday.

Discussion

There is little to no change in forecast philosophy from last evening. Surface troughing to our east has weakened the subtropical ridge, causing winds to become light and variable across local waters. Upper ridging pushing over the area from the west will keep our airmass stable, limiting shower coverage and intensity. This relatively dry, light wind weather pattern is expected to persist into next week. Light background flow will allow development of local land and sea breezes. Land breezes will lead to mostly clear nights and mornings while converging sea breezes will drive cloud formation over island interiors during afternoon and early evening hours, possibly triggering a few showers.
Expect a few minor variations from an otherwise extended period of light winds and dry weather. A weak high passing north of the area turned light winds to the north and northeast this morning, overriding the land breezes to push a few showers across windward areas. Expect winds to become variable again later today as the weak high moves away. A surface trough southeast of the Big Island will move slowly west. Associated moisture may increase cloud cover and fuel a few showers across windward Big Island tonight and Friday, while also increasing winds to moderate speeds. This moisture is expected to move east over the weekend, but models show it will move back toward the Big Island Sunday night and Monday, potentially increasing clouds and showers over southeast and windward portions of the Big Island. A weak front moving into the area from the northwest on Saturday may induce a short period of light to moderate northwest to north winds. This front may also bring an increase in showery low clouds Friday night and Saturday, mainly over Kauai and Oahu, with the front dissipating by Sunday.

Aviation

A weakening cold front stalling northwest of the state will keep light and variable winds in the forecast into Friday. A light background northeasterly wind will interact with land and sea breezes over each island today. Mostly VFR conditions are expected.
No AIRMETs are currently in effect or anticipated at this time.

Marine

Light to moderate northeast trade winds will persist over the eastern waters through Friday, while light and variable winds prevail over the western end of the state. today, strongest over the eastern end of the state. As a front approaches from the northwest Friday night, light to moderate west-northwest will briefly develop over the western waters. The front will move into the western islands on Saturday, with winds shifting around to the northeast at light to moderate speeds. Winds will become light and variable Saturday night and Sunday as the front stalls out over the western or central islands and dissipates. Winds may then pick up out of the southwest at light to moderate levels Sunday night and Monday, as a new front approaches from the northwest. A large northwest swell combined with a subsiding north swell will keep advisory level seas in place over exposed windward waters through tonight. Another round of advisory level seas is expected late Saturday through the middle of next week as a series of large northwest swells move through. Winds are expected to hold below advisory thresholds through the middle of next week.
A large northwest swell continues to run 2 to 3 feet above guidance early this morning, while the current north swell continues its slow decline. The northwest swell will generate warning and/or advisory level surf along most north and west facing shores through tonight. See the Coastal Hazard Message (CFWHFO) for additional details. An even larger northwest swell is set to arrive this weekend, with solid warning level surf expected for most north and west facing shores. North and west shore surf is forecast to dip to advisory levels Sunday night and Monday, before getting a boost back to warning levels Monday night through Tuesday night, then lowering to advisory levels Wednesday.
