Area Forecast Discussion National Weather Service Honolulu HI 940 AM HST Thu Jan 20 2022

SYNOPSIS. A weakening ridge over the state will produce one more day of light and variable winds. Expect afternoon clouds and a few spotty showers over island interior sections, while showers will be more widespread on the Big Island and Maui, especially on southeast slopes. High pressure passing north of the state will bring a return of light trade winds on Friday. Winds will increase to moderate strength trade this weekend and push an area moisture over windward slopes, followed by brief drying late Sunday into Monday. Another increase in trad wind showers is possible late Monday and Tuesday.

DISCUSSION. A surface ridge will remain over the state and produce light and variable winds for one last day. The ridge currently stretches over Kauai and is producing east to southeast winds around the Big Island that shift out of the south over the Garden Isle. An area of diffuse low level moisture is being pushed onto southeast slopes of the Big Island and Maui this morning. Expect showers to persist along these slopes today, while afternoon sea breezes produce more extensive afternoon clouds and showers along leeward Big Island and Maui as compared to the last several days. Ridging aloft will maintain stable conditions and inhibit heavy shower development. For Kauai, Oahu, and Molokai, afternoon sea breezes will lead to scant shower activity. The weakening surface ridge will hang on tonight, leading to overnight land breezes and clearing over most areas.

Friday will be a transition day, with trades staging a comeback. Surface high pressure will build north of the state while a cold front stalls and begins to dissipate within 100 miles north of Kauai. Initially, conditions will be rather dry, but moisture from the dissipating front may be pushed into windward Kauai and Oahu Friday night.

Trade winds will increase to moderate strength on Saturday as a surface ridge holds north of the state, and trades will likely shift out of the northeast on Sunday as a weak surface approaches from the east. The moisture from the dissipated front should clear out and lead to a decrease in showers Sunday afternoon. In addition, an upper level low dropping southward to the east of the state will produce increased north winds on the high summits of the Big Island.

Expect trade winds to remain in place through next week, possibly becoming breezy and gusty by Wednesday. The above mentioned surface low will fall apart, but its remaining moisture will fuel windward rainfall for parts of the state late Monday and Tuesday, especially for the Big Island and Maui.

AVIATION. With a surface ridge over the western end of the state, winds will remain light to moderate. Sea breezes will develop during the day over many areas, with land breezes taking hold in the overnight hours. Showers will mainly form over mauka and interior sections during the afternoon and early evening, with clearing as the nighttime progresses. Also, a weak east wind regime over the Big Island this morning is bringing showers into the eastern and southeastern parts of the isle.

A weak trade wind flow will likely return statewide Friday as the surface ridge moves north of the islands.

No AIRMETs are in effect, and none are anticipated through tonight.

MARINE. A surface ridge over the area will continue to support light to locally moderate winds into tonight, favoring an E to SE direction near the Big Island, and SE to S near Kauai. A weakening front moving toward the area will cause the ridge to move S and weaken and light and variable winds will prevail from tonight into Friday. A high pressure cell passing N of the area will then support moderate to locally fresh NE winds from Friday afternoon into early next week, potentially reaching Small Craft Advisory (SCA) levels over the typically windy waters around Maui County and the Big Island. The passing high will also push fragments of the front over the area, leading to an increase in showers, mainly over windward waters Friday and Saturday.

The current NW swell is on the slow decline today as available buoy observations indicate the swell is diminishing in height and period. This will only be a temporary lull however, as a powerful long-period WNW swell is expected to build Friday, peak Friday night/Saturday, then gradually diminish through Sunday. Surf heights are expected to reach or exceed High Surf Warning (HSW) criteria during the peak of the swell for exposed N and W facing shores, including the W facing shores of the Big Island. After dropping below HSW levels, continued reinforcements from the WNW may require a High Surf Advisory (HSA) through early next week. The weekend's large WNW will bring combined seas over 10 feet, requiring a SCA for seas in most zones. Additionally, a small to moderate ENE swell is possible over the weekend, generated by a gale low E of the islands. There will be also a slight increase in short period choppy surf for east facing shores as moderate to fresh trade winds return.

HFO WATCHES/WARNINGS/ADVISORIES. None.
