Detailed Forecast

Synopsis

Showery cloud band remnants will move across Kauai today. Trade winds will push over the eastern end of the state late this afternoon and will bring a band of moisture along with it. This moisture will spread westward as the trades fill in across the rest of the state tonight and Saturday. A typical trade wind weather pattern is expected for the weekend and into next week.

Discussion

A ragged showery cloud band lingers across Kauai this morning and will bring light to moderate showers to that island through today. Elsewhere, overnight land breezes cut off shower activity and cleared skies over land. Cloud cover will likely increase once again over mauka areas as daytime heating sets in. Expect trade winds to gradually return beginning this afternoon as high pressure strengthens northeast of the state. Models show increasing showers as the trades spread westward, starting with windward areas of the Big Island this afternoon. By Saturday afternoon, trade winds will spread statewide.
Models show a moderate to locally breezy trade wind pattern across the state for next week, with showers riding in with the trade winds each day. Ridging aloft will keep our airmass stable, limiting total rainfall amounts. However, an increase in cloud and shower coverage is possible towards the middle of next week.

Aviation

A dissipating stationary front near Kauai will bring enhanced shower activity to areas west of Oahu this morning. This may allow for brief periods of MVFR ceilings and visibility. Elsewhere across the island chain, expect mainly dry conditions with partly cloudy skies and isolated showers.
This evening into tonight, southeasterly winds will back to a more easterly direction and bring a return of windward showers, especially over eastern portions of the Big Island.
AIRMET SIERRA remains in effect for Oahu and Kauai above 2500 feet due to reduced visibility from low clouds and showers.

Marine

A weakening boundary is over the western part of the state, near Kauai this early morning, and is heading west. Winds with a southerly component across the area will back toward the east over the next day or two and strengthen as high pressure builds far north and northeast of the islands. Moderate to strong trade winds will then continue through the middle of next week.
The current north swell remains elevated, though it has peaked. It will gradually lower through tonight. The High Surf Advisory was cancelled with the declining swell, but surf heights will remain near the 15-foot advisory threshold through the morning hours. No other significant northwest or north swells are likely through the middle of next week. And the Small Craft Advisory was also cancelled as combined seas have fallen below 10 feet.
Small, long-period south swells will maintain current south shore surf through Saturday. With no significant trade winds over and upstream of the state, most eastern shore surf will be from north swell wrap. However, strengthening trade winds this weekend will create rising, choppy surf along east facing shores.
