Looking ahead, trade winds will gradually strengthen through Sunday, with predominantly dry conditions expected for the weekend.
However, as a weak upper-level trough approaches the area, an increase in rain activity is anticipated starting Monday, likely lasting through at least the middle of next week.
Bands of moisture could lead to some showery weather, particularly in windward and mountain locations.
Radar and satellite imagery show stable stratocumulus clouds across many areas but with little rain reported.
A strong inversion around 5000 feet is limiting the vertical development of clouds observed this afternoon.
As forecasters look to Sunday, dry and stable conditions are likely to prevail with reinforced trade winds resulting in breezy weather.
Heightened fire weather concerns are anticipated for Sunday, particularly across Maui County and parts of the Big Island, where drier fuels meet stronger winds.
Residents and visitors alike are urged to maintain caution with any activities that might ignite sparks in outdoor settings.
On Monday, expect a noticeable uptick in showers as the upper-level trough approaches the state, leading to more active periods of showery weather persisting through the midweek.
Although no significant rainfall is expected, the anticipated showers may influence outdoor plans due to intermittent moisture bands moving through various parts of the island.
Windward and mountain locations will likely experience the most rainfall on Tuesday or Wednesday of the upcoming week.
In the extended forecast, as the upper-level trough shifts westward away from the islands late next week, a ridge will build from the east.
While passing showers are still likely, they are expected to be less frequent and less intense than those seen earlier in the week.
As we move into Tuesday and Wednesday, trade winds will gradually lessen as the high pressure weakens north of the islands, with moderate to locally breezy conditions projected by midweek.
In terms of aviation, high pressure will remain northeast of the islands, increasing breezy trade winds through tomorrow.
Limited shower activity is anticipated under a drier, more stable air mass, although a few clouds and brief showers may favor windward and mountain segments.
While brief MVFR conditions may arise, the overall forecast indicates VFR conditions should prevail.
Meanwhile, AIRMET Sierra remains in effect for temporary mountain obscuration in windward regions of Oahu and Kauai due to persistent MVFR ceilings.
AIRMET Tango may also be issued this evening as low-level winds increase under the prevailing inversion.
For marine conditions, high pressure northeast of the islands will ensure fresh to strong trades tonight through Sunday, tapering slightly into early next week with a Small Craft Advisory currently in effect.
Small to moderate period southwest swells will remain below average until Monday when a new moderate long period swell begins to arrive.
This swell could peak by Tuesday, nearing High Surf Advisory levels, coinciding with the peak of king tides that may pose risks for coastal flooding in susceptible areas.
Compounding the coastal flooding threat, a continuing southwest swell will enhance impacts.
A Small Craft Advisory is in place for the Oahu Leeward Waters, Kaiwi Channel, Maui County Windward and Leeward Waters, and the Big Island Windward Waters until 6 PM HST on Sunday.
Overall, residents and visitors in the Big Island areas should prepare for variable weather conditions and possible disruptions to their outdoor activities.
For further updates, locals are encouraged to remain tuned into local weather services.
