Area Forecast Discussion National Weather Service Honolulu HI 343 PM HST Tue May 26 2020

SYNOPSIS. Light trade winds tonight and Wednesday will strengthen to moderate to locally breezy levels during the second half of the week, and continue into the weekend. The trade winds will focus low clouds and showers over windward areas. Varying amounts of benign high clouds are expected to move over the islands through Friday.

DISCUSSION. No significant changes to the forecast or the general thinking. However there have been some short term changes, mainly to increase PoPs over the windward sides of the islands tonight. In satellite animation, we can see some low clouds riding in on the trades to the east of the Big Island and Maui. Anticipate an uptick in shower activity in those areas overnight as a result.

The ridge to the north of the islands is expected to lift the north, which will allow trade winds to filter back into the region from south to north. We are seeing some light trade winds this afternoon, and expect those to become more widespread tonight and Wednesday. A new high building in north of the islands will help to increase our trades to moderate levels through the weekend.

Meanwhile, an upper level low to the southwest of the islands is ushering in some high clouds from the south, and those clouds have spread over the Big Island to Oahu by this afternoon. The upper level low is expected to gradually move to the west, which will spread the high clouds to Kauai by Wednesday morning. The high clouds will linger through Friday, before thinning and exiting the area to the west. Have boosted the Sky grids through the time period to better account for the presence of the high clouds.

With the returning trade winds, expect showers to be focused over the windward sides of the islands. As mentioned above, an uptick is likely tonight over windward slopes of the Big Island and Maui. Otherwise passing showers will be the norm over the next several days. There are indications in the long range models that we could see an increase in trade wind shower activity early next week.

AVIATION. Expect late afternoon sea breezes to develop with light winds still in place with possibly a few inland showers. That should change beginning tonight as the high builds and strengthens to the northeast, increasing the northeast trade winds speeds. That trend should continue for the next few days. This means that any showers that develop will favor windward mauka areas with passing MVFR conditions in those areas as well, especially overnight and into the early morning hours. VFR conditions are to be expected elsewhere.

There are no AIRMETs currently in effect.

MARINE. A ridge of high pressure about 240 nm north of Kauai will gradually lift north over the next few days, then persist just outside of the offshore waters through the weekend. This will cause the return of easterly trade winds with wind speeds becoming fresh to locally strong by Wednesday night. Currently we have no marine warnings posted, but Small Craft Advisory conditions are expected to return to the typical windy areas around Maui and the Big Island by Wednesday night.

Surf along north facing shores should see a small reinforcing north-northwest swell fill in through the day Wednesday with a peak expected Wednesday night. As this swell declines Thursday and Friday, a new north swell should fill in late Friday into Saturday.

Surf along south facing shores will remain near the summer average through the weekend as a series of small south-southwest and south-southeast swells moves through. An upward trend is expected next week with a moderate south swell possible by the middle of next week. This swell is due to a strong storm-force low currently southeast of New Zealand.

Surf along east facing shores will remain below the May average through the weekend due to the lack of strong trades upstream of the state.

For more details on surf see the latest Collaborative Nearshore Swell and Wind Forecast for Oahu (SRDHFO).

HFO WATCHES/WARNINGS/ADVISORIES. None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
