Detailed Forecast

Synopsis

Strong high pressure northeast of the islands and increasing stability will keep windy and rather dry trade wind weather around for the next few days. Scant showers will favor windward and mauka areas, with only light total rainfall expected. The strong winds may blow a few showers across leeward areas from time to time as well. Shower coverage may increase slightly late Monday and Tuesday as remnants of an old front pass through from the northeast.

Discussion

Strong trades continue as the islands feel the squeeze between strong 1035mb high pressure centered near 35N and a well-defined surface trough south of the Big Island. The increase in the local pressure gradient has also been accompanied by the rapid development of a strong and shallow inversion that slopes from around 4kft at Lihue to 5kft at Hilo. This not only forced trades to strengthen today but also provided a favorable environment for local accelerations in the windier locations of Maui County and the Big Island. The wind advisory will remain in effect through tonight.
Dry trades will hold firm tonight into Monday as existing high stability is reinforced by a very dry ~850-750mb airmass moving into the area from the east. Trades will weaken to breezy during this time, focusing limited showers over windward zones as high clouds slowly peel off to the north and east. Trades will usher in a band of remnant frontal moisture Monday night bringing an uptick in light windward showers Monday night. Otherwise, relatively dry weather continues through mid-week as building mid-level ridging brings continued continued stability and ensures rainfall stays on the lighter side.

Aviation

A large area of high pressure north northeast of the state will continue to bring moderate to breezy easterly trades across the islands tonight. Thus, scattered showers will mainly affect windward areas with very little precipitation elsewhere. Brief MVFR ceilings and visibility may occur with this activity, though not expecting anything widespread.
AIRMET Tango remains in effect below 7000 feet over and immediately south through west of mountains due to tempo moderate turbulence.

Marine

Strong trades will continue tonight, with Gale-force conditions in most of the windy waters around Maui and the Big Island. A Gale Warning remains in effect for these waters through 6 AM Sunday, with a Small Craft Advisory (SCA) in place for all other waters. The trades will ease into the moderate to locally strong range Sunday, then hold at those levels through the work week. The SCA will likely be scaled back to mainly the eastern waters on Sunday.
Surf along east facing shores will hold at or above normal levels through next weekend due the persistent moderate to strong trades over and upstream of the islands. Otherwise, surf along north, south, and west facing shores will remain small through next weekend.
