The current north-northeast swell will continue to subside through Sunday with a new northeast swell expected to arrive Sunday night, peaking first thing Monday below advisory levels. The surf has continued to decline at all the nearshore buoys, but remain high enough to keep the High Surf Advisory for east facing shores this morning. Expect the seas to continue to decline Saturday, with surf falling below advisory levels for the east facing shores by midday. The winds settled a bit overnight, but are expected to have a little boost Saturday morning. Meanwhile the above mentioned swell will continue to decline with seas expected to drop below the 10 ft mark by midday. Winds are likely going to remain strong enough for a small craft advisory for some of the typically windier locations into Sunday. Another northwest swell is expected to arrive Tuesday, peaking below advisory levels Wednesday. Another more northerly swell is possible later in the week.

Weather Outlook for Saturday

A stationary front over Maui will linger through today and then dissipate. Numerous showers will continue along the front, mainly across windward areas of Molokai and Maui. An upper level trough passing over the state this morning may trigger a few heavier downpours along the front. Cool and mainly dry weather will prevail across Oahu and Kauai. Weak high pressure will build north of the islands behind the front Sunday and Monday, with trade winds gradually weakening and rather cool weather continuing. Gentle trade winds and mainly dry weather will prevail through the first half of next week.

Active weather Friday evening over the eastern half of the state has quieted down somewhat early on this Saturday morning. Areas of light to locally moderate rain continue to affect windward sections of Maui and Molokai, but rainfall rates are lower than was observed last evening. No thunderstorms have been observed over the islands or adjacent coastal waters for the past several hours, after isolated storms developed early Friday evening. Mainly dry and cool conditions prevail over Oahu and Kauai, with just patchy light rain and drizzle lingering over some windward areas. A notably cool and dry airmass has spread into western parts of the state behind the front, with air temperatures over Oahu and Kauai early this morning mostly in the mid 60s, and and dewpoints in the upper 50s to near 60 degrees.

A stationary front remains over Maui, with an upper level trough moving over western parts of the state. Abundant high cloudiness is streaming over the eastern part of the state ahead of this trough. Water vapor imagery shows that the trough is moving steadily eastward. The 12Z Lihue sounding showed the drier airmass behind the front, with PW of 1.08 inches and an inversion based near 10K feet. The 12Z Hilo sounding was more moist with PW of 1.48 inches, but relatively stable with a couple of inversions based near 5K and 15K feet.

Rather wet weather will continue over windward sections of Molokai and Maui today near the front, with only scattered showers over the windward Big Island, and mainly dry conditions over Oahu and Kauai in the cooler airmass behind the front. Recent satellite/radar/sounding data suggest that the deeper moisture is starting to exit the state to the east, and with the upper trough continuing to move eastward today the potential for heavy rain along the stalled front should end by this afternoon. Will continue to mention locally heavy rains possible for windward areas of Maui and Molokai this morning. Over the Big Island summits, while cold conditions with a few snow showers will continue today, the departure of the deep moisture that was over the area Friday evening should allow for gradually improving conditions, and we have cancelled the winter weather advisory.

By this afternoon and evening, the cooler/drier airmass will spread across central parts of the state, as the upper trough moves east of the islands. Shower activity should decrease during this time as the upper support exits and moisture along the old frontal boundary becomes increasingly shallow. High-resolution models show another surge of northeast winds moving across the islands during this time, so some areas will see breezy conditions to go along with the rather cool temperatures. Moderate northeast winds along with continued cool temps and mainly dry conditions should prevail across the state for New Years Day. The best rain chances will occur on windward sections of the Big Island and east Maui, with little if any rainfall expected elsewhere.

Gentle trade winds with mainly dry conditions are forecast to prevail through the first half of next week as a weak surface ridge lingers just north of the state. Another weak front may approach the islands from the north around midweek, but models remain inconsistent with the exact timing and southward movement of this feature. Overall, a rather quiet weather pattern appears likely to prevail across the state during the first week of 2017.
