Fresh to strong northerly winds will continue to filter southward today as a cold front across the Big Island passes east of the state. Trades are forecast to return by Sunday as high pressure builds north of the state.

The northwest swell will slowly decrease through the rest of the weekend. A moderate, short-period north swell will build quickly today. The combination of these two swells will keep surf at advisory level along north facing shores, so the High Surf Advisory (HSA) remains in effect through this afternoon for north facing shores of the smaller islands. This source will fade into early next week. Surf will also increase along east facing shores today as the building north swell energy wraps in, and is expected to reach advisory level. Therefore, the HSA also covers east facing shores through this afternoon.

The Small Craft Advisory for most waters remains in effect through tonight due to a combination of swell and strong northerly winds expected behind the front.

Weather Outlook for Saturday, 26th January 2019

Summary

A weak cold frontal boundary southeast of the state will continue to spread clouds and showers over Maui and the Big Island through the morning hours. Cool and breezy north to northeast winds are forecast with mostly sunny skies for all other areas. Trade wind weather will continue through next week with clouds and some showers favoring windward and mountain areas.

Detailed Discussion

The leading edge of the cold front has passed through the Big Island this morning. Clouds and showers will continue to spread over north and east sections of Maui and the Big Island this morning. Drier and cooler air moving in from the north today will reduce clouds and showers over both islands through the afternoon. Strong upper level winds at 600 MB’s will support advisory level winds over the Big Island summits of Maunakea and Maunaloa today. The Wind Advisory (NPWHFO) for both summits was extended into the evening time period.

A cool, dry and breezy north to northeast wind will blow in behind the front with high and low temperatures falling a few degrees below normal for this time of year across Hawaii Nei. Much drier air will move into the islands from the north with Precipitable Water (PW) levels falling below the 0.75 inch threshold. Expect mostly sunny weather for most areas this weekend in a stable atmosphere. An upper level trough passing to the northeast of the state may bring some elevated showers to the north and eastern slopes of the Big Island on Sunday. These cool temperatures will last through Sunday before the temperatures start warming back up early next week.

Fair weather conditions remain in the forecast for most islands through the week with a strong high pressure system anchored far to the north of the islands providing dry and stable weather across the region. One hitch in this mostly dry forecast hinges on the movement of an upper level low drifting down from the north across the eastern half of the state on Tuesday. This low rapidly weakens as it passes just east of the Big Island on Tuesday afternoon and evening. Some upper level instability, associated with this low, may elevate showers along the north and eastern slopes of the Big Island on Tuesday night. Otherwise a drier trade wind weather pattern will prevail through Friday with clouds and some showers will favoring typical windward and mountain locations through the week.
