Breezy trade winds will continue into early next week due to surface high pressure far north of the islands. A Small Craft Advisory remains in effect through Monday afternoon for the typically windier waters adjacent to the islands of Maui County and the Big Island. The latest forecast indicates that SCA winds will likely persist for most of these same waters from Monday night through the middle of next week.

The breezy trade winds will generate modest choppy surf along east facing shores of the islands from this weekend into early next week. A long fetch of strong trades developing east and northeast of the islands next week may cause a slight increase in surf heights along east facing shores by the middle of next week. Small southeast and south swells will maintain small background surf along south facing shores through the middle of next week.

Weather Outlook for Saturday, 28th July 2018

Summary

Moderate to breezy trade winds will persist into next week as high pressure holds firm north of the state. Stable weather will continue, focusing showers over windward slopes and supporting some afternoon showers over the leeward slopes of the Big Island. An area of tropical moisture may bring an increase in showers to portions of the state sometime between Wednesday and next Friday.

Detailed Discussion

A stable trade wind flow remains in place with patches of high clouds affected mainly the western half of the state. A 1031 mb surface high sitting over 1,800 miles northeast of the state is driving the trades. A ridge aloft centered overhead is maintaining stable conditions with an inversion holding between 4,000 and 7,000 ft according to the Lihue sounding and recent aircraft data. Rainfall has been modest overnight and focused over windward Big Island. An upper level trough far west of the islands is triggering thunderstorms 600 to 700 miles southwest of Kauai and sending scattered to broken high clouds over the western end of the state.

Expect only subtle changes in local weather through at least Tuesday. The trades will drop slightly on Sunday, then pick back up during the first half of next week as high pressure strengthens to the north of the state and a weak trough passes south of the islands. Stable conditions will remain in place as the ridge aloft stays parked overhead. Random pockets of moisture will move through, affecting mainly windward slopes. High clouds will periodically stream over mainly the western end of the state as the upper level trough stays off to the west.

An increase in shower activity is possible during the middle to end of next week. East Pacific Tropical Depression Gilma is forecast to dissipate well east of the state, but its associated moisture may impact the islands as early as Wednesday and continue into next Friday. The highest chance for precipitation looks to be across the windward Big Island, as models keep the bulk of the remnant moisture south of the island chain.
