Area Forecast Discussion National Weather Service Honolulu HI 824 PM HST Sat Jul 20 2024

SYNOPSIS
Trade winds will gradually strengthen over the next couple of days as a stable pattern of mainly windward showers prevails. A batch of moisture moving in the trade wind flow will produce an increase in showers Monday night and Tuesday. Trade winds are expected to strengthen Wednesday and Thursday, bringing drier weather.

DISCUSSION
A shallow batch of moisture that moved over the island chain today is clearing this evening, allowing a stable trade wind flow to return. The moisture was not very impressive, leading to a slight boost in windward rainfall from the Big Island to Oahu.
However, the increase in shower activity was more extensive on leeward Big Island, where daytime sea breezes tapped the moisture.
Rainfall on the Kona slopes will gradually taper off through midnight, while showers will be minimal elsewhere.

Expect a drier and slightly stronger trade wind flow to prevail on Sunday and Monday. A surface high far north of the state will gradually build, leading to the uptick in trades, and mid-level ridging will hold firm, maintaining stable conditions. Drier air will slowly move in on the trade wind flow, leading to minimal windward rainfall and mostly dry conditions leeward. Exceptions will be on the Kona slopes of the Big Island, where clouds and showers will develop each afternoon, and leeward Kauai, which could see a couple of brief showers Sunday afternoon.

An increase in shower activity is due Monday night and Tuesday as another batch of moisture moves in on the trades. This area will be deeper than the one that passed through today, which suggests that shower chances will be higher, especially for windward areas.
Leeward slopes of the Big Island, and possibly Haleakala, will likely be active Tuesday afternoon, while leeward areas elsewhere will experience a few passing showers. A mid-level trough will accompany the moisture, but generally stable conditions will remain aloft, minimizing chances for any heavy rainfall.

Drier conditions and stronger trade winds will develop Wednesday and Thursday as the mid-level trough moves away and the high to the north builds. Expect minimal windward rainfall and dry conditions over most leeward areas.

AVIATION
Moderate trades will continue for the next several days with clouds and showers favoring windward and mauka areas, particularly overnight. In addition, clouds and showers will build up on the Kona slopes of the Big Island each afternoon. A few of the showers could bring brief MVFR conditions. Otherwise, VFR should prevail.

No AIRMETs are currently in effect.

MARINE
A strengthening high pressure system far north of the Hawaiian Islands will increase the trade winds into the fresh to locally strong range tonight. Trade wind speeds will be strong enough to support Small Craft Advisory (SCA) conditions over the windier waters and channels near Maui and the Big Island through much of next week. An SCA has been issued for these waters through Sunday night. Additional waters will likely be added next week as wind speeds increase from Monday into Tuesday.

Background south swell energy pulses are forecast to continue, with surf remaining below average through much of next week.
Small, choppy surf will increase along east facing shores as locally strong trade winds increase over the next few days.

Spring tides will peak this weekend, with local tide gauges showing water levels are still running about a half a foot above guidance and at least 1 foot higher than the Mean Higher High Water (MHHW) threshold at Hilo, Kahului, and Honolulu. The Coastal Flood Statement for isolated minor flooding remains in effect through Monday evening.

FIRE WEATHER
A typical summer trade wind weather pattern will prevail into Monday, followed by wetter conditions Monday night and Tuesday. On Wednesday and Thursday, trade winds will strengthen, and somewhat dry and stable conditions will develop. This could lead to some fire weather concerns.

HFO WATCHES/WARNINGS/ADVISORIES
Small Craft Advisory until 6 AM HST Monday for Maalaea Bay- Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.
