Area Forecast Discussion National Weather Service Honolulu HI 924 AM HST Sun Jun 23 2024

SYNOPSIS
High pressure north of the state will maintain breezy trade winds the next few days. Showers will primarily favor windward coasts and slopes. Trades will weaken slightly around the middle of the week, with a possible uptick in shower activity late in the week.



DISCUSSION
The downstream pressure gradient from a 1030 mb high centered approximately 950 miles north of Kauai remains tight enough across the island chain to continue breezy trades the next few days. The Hawaiian Islands will remain under the stabilizing influence of mid-level ridging as the area falls along the southeasterly periphery of the 700 mb ridge positioned to the northwest. Water vapor imagery continues to show a drier air mass over the islands this morning with widely scattered weak trade showers.

While morning sounding precipitable waters fall in-line with late June climatology numbers (1.3-1.4 inch pwats), mid to upper level northeasterly drier air advecting into the state will limit overall shower activity today with light, isolated showers primarily confined to windward coasts and slopes. Slightly higher mid- level moisture advecting in Monday, along with a 6-7 kft fairly saturated layer, may be enough to increase shower coverage and produce a few hundredths more rain in those communities that typically stay wet during a normal trade flow pattern. Little to no movement of the lower and upper ridge planted north of the islands through Tuesday ensures breezy trades under partly to mostly cloudy windward skies...mostly to partly sunny leeward skies. High pressure at all levels begins to transition east during the latter half of the week. This will weaken the lower level pressure gradient enough to subtly suppress trade flow to more gentle magnitudes, although easterlies will still remain breezy along ridge lines and within more east-to-west orientated valleys. Lowering mid to upper heights, with periodic ribbons of higher moisture passing to the west, will increase shower frequency and areal coverage later in the week. Higher confidence in the development of an upper level disturbance east northeast of the islands will certainly boost weekend rain chances as we close out the month of June.



AVIATION
Breezy to locally windy trades will continue through Monday.
Showery cloud bands embedded in the trade flow will produce periods of MVFR conditions across windward/mauka areas of each island, particularly through the overnight and early morning hours each day. Conditions will improve through the late morning and afternoon periods.

AIRMET Sierra remains in effect for tempo mountain obscuration for windward slopes of most islands, which will likely continue through today.

AIRMET Tango remains in effect for mod low-level turb over and downwind of island terrain due to the breezy trade winds. This AIRMET will continue through Monday.



MARINE
Strong easterly trades continue through early this week, and the Small Craft Advisory remains in effect for all waters through Monday night. Trades then weaken slightly Tuesday into midweek.

Surf along east-facing shores will remain rough and choppy through Monday followed by a gradual downward trend during mid-week as trades weaken slightly.

Expect slightly elevated surf near or slightly below seasonal norms along south facing shores through Tuesday as a small, medium to long period, south swell moves through. The swell has already shown up on the Barbers Point Buoy with energy in the 14-16 second bands. However, this should be short-lived, with a downward trend expected by Tuesday night. Despite a blocking high that has set up over our typical swell window southeast of New Zealand, a gale has formed northeast of this high with the head of the fetch aimed at the islands within the 180 to 200-degree directional band. Given the shorter travel distance, surf associated with this source should trend up late this week.

Nearly flat conditions along north facing shores today. A small, medium period, northwest swell will bring tiny surf to north facing shores late Monday through mid week.
