Overall, the weather forecast suggests a pattern of moderate to locally breezy east-southeast trade winds that will continue into the coming days.
A broad surface trough developing to the west of the islands is projected to enhance showers temporarily, particularly favoring windward and mauka regions during nights and leeward areas during afternoon hours.
Advancing into Monday night, a more stable easterly trade wind pattern is predicted, aiding the decrease in shower activity as upper level heights rise, and drier air begins to filter in from the east.
As the week progresses, expect more typical easterly wind conditions to dominate the weather pattern, with possible easing of the trade winds by next weekend.
Current atmospheric conditions include a shift to an east-southeast steering flow, causing low-level clouds and showers to ride along the trades, creating variable weather across the island chain.
Meteorologists have noted that the conditions leading up to the broad surface trough are influencing the current high cloud coverage, particularly impacting the western regions of the island.
This pattern gives a glimpse of what is expected through the short term, while vog remains a concern, especially as the east-southeast flow pushes it across the islands and momentarily westward by midweek.
Aviation conditions indicate moderate to breezy east-southeasterly winds continuing through Monday, potentially leading to mountain obscuration, particularly over Kauai and Oahu.
The forecast anticipates that VFR conditions will be most common, but there may be periods of MVFR ceilings and visibility due to existing passing showers.
AIRMET Sierra and AIRMET Tango are currently effective for mountain obscuration and moderate turbulence downwind of the islands’ terrain, likely remaining in effect into Monday.
In terms of marine forecasts, fresh east-southeast winds are expected tonight, with a Small Craft Advisory in place due to stronger winds anticipated over typical windy waters and leeward Maui waters through Monday.
As the surface ridge rebuilds to the north, trade winds are expected to shift back to their usual easterly direction, with the advisory likely adjusted accordingly.
The late-season northwest swell will decrease, while south-facing shores continue to see a mix of small background swell, followed by the potential of a more significant swell late Tuesday and Wednesday.
A long-period south-southwest swell is forecasted to build on Friday, potentially leading to surf well above average by the weekend.
Overall, the weather report emphasizes how dynamic conditions will evolve over the next few days and the careful watch that meteorologists will maintain over changing weather patterns.
