Area Forecast Discussion National Weather Service Honolulu HI 400 AM HST Mon Jan 20 2020

SYNOPSIS. Breezy trade winds will continue today, then shift out of the southeast and diminish Tuesday through Friday. A mostly dry land and sea breeze pattern will result, with the best chance for a few clouds and showers setting up over interior areas through the afternoon periods. A front will stall and weaken near Kauai Friday with trades briefly returning Saturday.

DISCUSSION. A broad surface high centered just north of Hawaii will provide stable conditions and breezy trade winds today. Dew points are in the low to mid 60s across the state this morning with morning soundings at Hilo and Lihue indicating a strong inversion around 6 kft and precipitable water around 1 inch. Infrared satellite and radar both show an area of concentrated low clouds and showers that arrived last night and will move across the area, particularly Oahu and Maui County, through the morning. The low inversion should keep most of the rain and clouds windward, but may see an occasional shower reach the leeward side due to the breezy trades. The clouds and showers should dissipate by this afternoon and any rainfall will be on the lighter side.

A progressive pattern setting up over the northern Pacific is expected this week as the polar jet becomes highly zonal. Two fronts will passing to the north this week, with possibly a third early next week. The first front will shift the surface high towards the southeast and bring the associated ridge over the islands. The winds will respond by veering southeast and diminishing Tuesday through Friday, allowing a land and sea breeze regime to setup. Rain chances will remain limited due to the dry air and strong subsidence expected to continue through this time period. The best chance for a few clouds and light showers will shift over interior areas through the afternoon hours each day.

Long range GFS and ECMWF stall and weaken the second front near Kauai on Friday, with possible an uptick in showers for the northern end of the state. Trade winds may briefly return Saturday as a bubble high quickly passes north of the state before the next passing front to the north causes the wind to veer out of the southeast Sunday. This front is expected to weaken as it nears the island early next week, but it's too early to tell if it will directly impact the state.

AVIATION. Overnight, stratocumulus reformed near Kauai and Oahu bringing some lower ceilings to windward areas. More showery low clouds can be found over the windward areas of Maui and the Big Island, as well as the adjacent windward coastal waters. The stratocumulus is expected to burn off by mid morning while some of the showers will linger over windward areas. Brief periods of MVFR conditions are possible with these isolated showers, but expect VFR to prevail overall.

Breezy trade winds warrant the continuation of AIRMET Tango for tempo low level turbulence below 7,000 feet. Trades will weaken later today and Tango should be able to be canceled by tonight.

MARINE. A surface high passing far N of the islands is supporting breezy to strong NE to E trade winds, and a Small Craft Advisory (SCA) remains posted for all waters through this afternoon. As the high moves steadily E and a front approaches from the NW the next couple of days, winds will veer and gradually weaken as the associated ridge moves closer to the islands. Winds will become mainly E today, light SE to variable Tuesday, and light and variable Wednesday and Thursday as the ridge moves over the islands. A new high passing N of the islands around Friday will push a second front toward the islands, while supporting moderate trade winds heading into next weekend, with the front currently expected to stall near Kauai and Oahu.

A new long-period NNW swell is expected to peak at low-end advisory levels today, thus a High Surf Advisory remains in effect for exposed N and W shores. This swell will diminish late today and Tuesday, but will be followed on Wednesday by a significantly larger NW swell that will likely peak near High Surf Warning heights, with an even larger swell potentially arriving next Saturday. Choppy surf along E facing shores will gradually diminish as winds weaken the next couple of days. Winds and seas have warranted an extension of the existing SCA through this afternoon, but diminishing winds and seas will allow its cancellation by tonight or Tuesday at the latest. However, seas associated with the two large NW swells discussed above will warrant an SCA for most areas later this week.

HFO WATCHES/WARNINGS/ADVISORIES. High Surf Advisory until 6 PM HST this evening for North and west facing shores of Kauai, Oahu, Molokai and Niihau, and north facing shores of Maui.

Small Craft Advisory until 6 PM HST this evening for all Hawaiian waters-

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
