The Honolulu Weather Forecast, provided by the National Weather Service (NWS), indicates a calming of northwest winds which will be replaced by a developing sea breeze/land breeze as a weak front fizzles out over the Big Island. National Weather Service's report notes that the state is in for a gradually wetter pattern from tomorrow into the early part of next week, with increased moisture driven by moderate northeast trades. Eyes will also be on another front that could sweep through parts of Hawaii from Sunday to Monday, potentially cementing the damp conditions and causing shifts in wind patterns.
Radar imagery, as noted by the National Weather Service, currently shows isolated to moderate showers near the Big Island, with predominantly dry conditions elsewhere. The dewpoints have decreased across various regions, signaling drier air but the Big Island will retain higher moisture levels. The typically arid boundary layer could limit interior cloud development, save for the Big Island where daylight warming could drive the creation of clouds and a smattering of interior showers.
From tomorrow through the weekend, island residents can anticipate enhanced wet weather. "Expect an increase in clouds and showers that will mainly along windward and mauka showers," the National Weather Service outlines. The moisture-rich pattern looks to persist with a subsequent weather front potentially acting as a catalyst for more widespread rainfall later in the coming week.
On the aviation front, a chilly and stable air mass behind the weakening front is expected to hang over parts of the state, with mountain obscuration an issue in certain locations. "Moderate to severe upper-level turbulence is expected to persist through the day over and N of the islands due to a sharp trough aloft," per National Weather Service's advisory. Mariners should also take heed as a Small Craft Advisory remains in effect through 6 p.m. tomorrow, owing to seas reaching in excess of 10 feet.
For beachgoers, the NWS cautions that a High Surf Advisory remains in effect for north facing shores until 6 p.m. HST Friday. Surfers should expect larger, disorganized waves resulting from a combination of northwest swells. Conversely, eastern shores will see surf levels below their typical rhythm and southern shores will experience minimal surf activity through the middle of next week. Lastly, despite low dewpoints posing potential fire weather concerns, winds are expected to stay subdued, thereby averting critical conditions.
