Detailed Forecast
Synopsis
Strong trade winds will gradually weaken over the next several days with moderate trades expected by the middle of the week. Showers will increase and will mainly be focused over windward and mauka areas with light rainfall amounts.
Discussion
Currently, looking at radar and satellite we have clouds showers moving across the islands with some upper level clouds streaming overhead during to a upper level low to the west.
Trades will gradually weaken over the next few days. A weak upper level trough will pass near the state late Monday into Tuesday. This could enhance showers particularly near Kauai through late Tuesday and maybe Wednesday. Some weak instability will be greatest near Kauai, which should allow for some periods of moderate rain. For rest of the state, the shower activity is not expected to be as frequent as Kauai, but some passing showers are expected through at least the middle of the week with windward and mauka locations getting most of the showers.
The aforementioned upper level trough should move westward and away from Kauai by Thursday with an upper level ridge building in from east. Drier conditions will be possible towards the end of the week and into the weekend. However some passing showers riding in on the moderate trades can't be ruled out.
Aviation
Breezy trades through today and will gradually decline through midweek. Windward and mauka showers expected with some limited spillover so some leeward areas. MVFR conds in heavier SHRA otherwise VFR prevails.
AIRMET Sierra is in effect for windward portions of all islands. Conds should improve in the morning hours.
AIRMET Tango is in effect for mod turb downwind of island terrain.
Marine
High pressure far northeast of the islands will drive moderate to locally strong trade winds through tonight before weakening during the remainder of the week. The Small Craft Advisory has been scaled back to the windier waters and channels around Maui County and the Big Island through tonight.
Surf along south shores will remain small through the early afternoon today until a moderate, long period south swell starts filling in slowly. This swell is expected to peak just below High Surf Advisory criteria on Tuesday before declining Wednesday.
Surf along east facing shores will remain rough and choppy through the week. Surf along north facing shores will remain tiny with mainly background energy through the forecast period.
Peak high tides associated with the lunar cycle will lead to minor coastal flooding along shorelines and low lying coastal areas through Thursday. A Coastal Flood Statement has been issued for the daily peak tide each afternoon and may be exacerbated by the ongoing south swell as it peaks on Tuesday.
