Synopsis for hawaiian coastal waters.. A cold front dissipating over the northwest waters tonight will keep the surface ridge in a weakened state through Sunday. Light winds will continue into the first half of next week as another cold front approaches the area from the northwest direction on Tuesday. Light to moderate large scale winds will allow land and sea breezes to develop in the near-shore waters of each island.

Area Forecast Discussion National Weather Service Honolulu HI 836 PM HST Sat Jan 15 2022

SYNOPSIS. Light and variable winds are expected through much of the upcoming week as a series of fronts pass north of the islands. Moisture associated with the tail-end of the fronts clipping the western end of the state as they pass will support better shower chances, especially over interior and mauka locations through the afternoon and early evening hours when sea breezes form. Otherwise, quiet conditions are expected with minimal rainfall.

DISCUSSION. Guidance remains persistent and advertises the active pattern holding over the northern Pacific, featuring a series of cold fronts passing the area to the north. The subtropical ridge has responded and shifted southward over the islands, which supports the ongoing land and sea breeze regime remaining in place through much of next week. Although the bulk of the weather associated with these passing systems will remain north of the islands, some moisture clipping the western end of the state along the tail-end of the passing fronts may act to trigger or enhance afternoon showers over interior and mauka locations when the sea breezes form. For the overnight and early morning periods, clouds and showers will tend to favor areas near the coasts and across our adjacent coastal waters.

The first front in the series moved into the area today and diminished into a weak trough near and north of Kauai. Satellite- derived PWs reflect this and depicts a residual moisture axis extending southwest through the western end of the state with values near 1.5" - which supports the ongoing showers around Kauai this evening and overnight tonight. Guidance suggests this moisture axis diminishing with a drying trend through the day Sunday. A similar scenario is expected Tuesday through Wednesday as the next front moves into the area, then again by next weekend.

AVIATION. Current radar trends show limited shower activity across the state, mainly confined southeast of the Big Island in the vicinity of an upper trough. Would expect only isolated showers in the vicinity of TAF sites through the remainder of the night, as weak high pressure and land breeze formation dominate the region. Otherwise, satellite data shows sea breeze clouds which formed earlier, continuing to diminish across most of the islands, while a layer of upper clouds drift in across the northern reaches of the state.

This afternoon, the weak wind pattern continues, allowing for diurnal sea breeze clouds and showers for interior sections and along slopes. Land breeze development during the evening will help diminish afternoon showers and clouds. Mainly VFR conditions are expected again today with some MVFR cigs possible in developing in heavier showers.

Currently, no AIRMETs are in effect. However, AIRMET Tango could be required later tonight through early Sunday for a potential period of mod upper lvl turb.

MARINE. A cold front dissipating over the northwest waters tonight will keep the surface ridge in a weakened state through Sunday. Light winds will continue into the first half of next week as another cold front approaches the area from the northwest direction on Tuesday. Light to moderate large scale winds will allow land and sea breezes to develop in the near-shore waters of each island.

The current west-northwest swell is building roughly 2 feet above forecast guidance this evening. A High Surf Advisory (HSA) remains in effect for exposed north and west facing shorelines through Sunday morning. This swell energy will peak tonight and then slowly decrease in height on Sunday, likely falling below advisory thresholds from Sunday afternoon to evening. The next west-northwest swell will move into the region early Tuesday, building to HSA levels by Tuesday night. This swell energy will peak on Wednesday night and fall below HSA thresholds on Thursday. Long range guidance continues to show a larger west- northwest swell arriving by Friday night, easily reaching HSA levels and possibly exceeding High Surf Warning thresholds by Saturday if the current wave model trends hold.

Elevated seas will periodically reach Small Craft Advisory (SCA) levels for exposed coastal waters as large swells move through this week. A SCA remains in effect for exposed waters surrounding Niihau and Kauai; including windward waters and channels near Oahu, Molokai and Maui.

HFO WATCHES/WARNINGS/ADVISORIES. High Surf Advisory until 11 AM HST Sunday for Niihau-Kauai Leeward-Waianae Coast-Oahu North Shore-Maui Windward West-Kauai North-Molokai Windward-Molokai North-Molokai West-Maui Central Valley North-Windward Haleakala.

Small Craft Advisory until 6 AM HST Sunday for Kauai Northwest Waters-Kauai Windward Waters-Kauai Leeward Waters-Kauai Channel- Oahu Windward Waters-Kaiwi Channel-Maui County Windward Waters.
