Honolulu is expected to have rainy and windy conditions in the coming days due to an upper-level trough west of Kauai. Windward slopes and higher terrain are forecasted to receive more rain and cloud cover due to breezy trade winds, as reported by the National Weather Service . Localized showers from a surface trough about 550 miles west of Kauai are interacting with a maritime trade flow, bringing moisture and overcast conditions expected to continue into Friday, with rainfall mainly in windward areas and upper elevations earlier in the day.
Forecast models indicate the upper-level low will weaken into a mid-level trough within 24 hours, remaining stationary before mid to upper-level ridging arrives on Saturday to stabilize conditions. A front is expected to reach the islands on Sunday, bringing showers and clouds, followed by drier air early next week, according to the National Weather Service in Honolulu. Easterly trade winds, moderate to breezy, are steady across Hawaii with an AIRMET Sierra issued for obscured mountain regions due to persistent showers.
A subtropical jet stream is producing moderate to severe turbulence between 25,000 and 39,000 feet, with a SIGMET SIERRA series issued for severe turbulence from 27,000 to 35,000 feet, expected to continue into the morning. Fresh to locally strong trades are forecast through the week, though an approaching front may weaken and shift these winds. A Small Craft Advisory is in effect for parts of Maui County and the Big Island, likely extending into Friday.
An extra-large northwest swell is anticipated on Sunday due to a hurricane-force low near the Kuril Islands, with rough east shore surf and minor swells along south shores, as stated by the National Weather Service ..
