For those in Honolulu looking forward to the weekend, the forecast calls for light, variable winds and mostly dry weather, transitioning from today's gradually diminishing trade winds, according to the National Weather Service. The Big Island's windward side will continue to see passing showers, but the rest will enjoy relatively clear skies.
The trade winds have been easing, and as we move into Sunday, conditions are stabilizing across most of the state. The high pressure system, which once stood prominently about 300 miles north of our bustling city, is weakening, reducing the chances of rain. While a weak front may pass over the islands late this weekend, it is expected to bring little moisture, leaving winds light throughout much of the week. An especially calm Thanksgiving forecast is on the horizon, as reported by the NWS.
In aviation news, expect showery weather and MVFR conditions over the windward Big Island today, while the rest of the island should experience fair weather with some sun peeking through scattered clouds. However, a mountain obscuration warning remains in effect for the Big Island above 2,500 feet and may persist throughout the day.
On the marine front, surface high pressure will promote gentle to moderate trades through tomorrow. Looking ahead, a weak front approaching Kauai on Sunday could shift the tranquil sea state to a more varied one. While not drastic, a series of swells from the northwest and north-northeast are expected to arrive over the next few days. These swells are not anticipated to reach advisory-level surf but could bring higher surf to north and east-facing shores. As these swells combine, they are expected to peak between Saturday and Monday, warranting close monitoring.
Lastly, the dry spell isn't just a topic of conversation, as KBDI values stay high and humidity might dip near critical levels until Sunday; fortunately, the modest trade winds we've been having should keep most fire weather concerns at bay.
