Honolulu residents can expect to see a convective weather pattern in the coming days, as light winds continue to dominate the region and showers are anticipated near the coast overnight and in the island interiors during afternoons and evenings. By the weekend, light to moderate trade winds are slated to make a return, however, the air is predicted to remain moist, suggesting a possibility of showers even in the usually drier leeward areas, according to the latest report from NWS - Honolulu Weather Forecast.As the current week advances, a weakening stationary front around 350 miles northwest of Kauai is keeping the winds meandering across the western islands, which has lead to a varied breeze pattern, while areas such as Maui County and the Big Island experience light to moderate east-southeasterlies, the NWS report outlined.
Over the weekend and into early next week, it is expected that moderate trade winds will reassert themselves, nevertheless, with a storm system taking shape west of Hawaii, another period of hefty rainfall and thunderstorms appears to be on the horizon for Tuesday and Wednesday.This unsettled atmosphere, partly due to an upper-level trough moving across the islands, has prompted a Winter Weather Advisory for elevations above 11,000 feet on the Big Island—effective from noon today until 6 PM Friday. This trough is anticipated to generate heavier afternoon and evening showers, and potentially isolated thunderstorms, with the Big Island summits likely to see snowfall as well.
When it comes to aviation, matters are a bit turbulent; a stalled frontal boundary together with an extensive trough over the island chain is creating irregular wind patterns, which in consequence, might bring about heavier scattered showers and occasional thunderstorms with potentially reduced visibility and ceiling in intense storms, local IFR conditions in more robust activity have been predicted by the NWS. Meanwhile, surf conditions along north and west-facing shores are expected to grow later today, potentially reaching advisory levels overnight due to a new swell arriving from the north-northwest, even as east-facing shores stay calm and south-facing swells continue to be small but could see an increase by next Tuesday.Mariners and the coastal populace will be dealing with a mix of light to moderate east-southeast winds until Friday, while land and sea breezes influence conditions near the coasts; a transition to moderate easterly trades is forecast for the weekend as high pressure builds to the north.
Finally, for those at high altitudes, particularly hikers and winter sports enthusiasts on the Big Island, the NWS's Winter Weather Advisory advises preparedness for chilly and challenging conditions until Friday evening..
