The overall weather synopsis indicates that gentle to moderate trade winds will prevail through Thursday as a weak surface ridge sits approximately 300 miles north of Kauai. Modest showers will likely remain focused over the windward slopes, though an upper-level disturbance may work to bring more rainfall to Kauai by late Tuesday and into Wednesday. High clouds mainly over the southern end of the island chain will also become noticeable as the disturbance continues.
Trade winds are expected to strengthen and stabilize by Friday and Saturday, providing somewhat drier conditions.
Analysts note that the current weather conditions stem from a weakened subtropical ridge located about 300 miles north of Kauai, with trade winds easing in response. A weak upper-level trough is located just north of Kauai, as thinner high clouds filter over the Big Island. A mid-level ridge is contributing to these stable conditions, with a moisture deficit contributing to low rainfall totals, primarily affecting Big Island and Kauai.
While rainfall totals have remained low, the good news is that no AIRMETs are in effect, and VFR (Visual Flight Rules) conditions are anticipated to prevail across much of the state through Tuesday. The slight weather disturbances leading to brief passing showers are mainly localized to windward areas.
As we move into the week, while trade winds are anticipated to strengthen, residents are encouraged to remain aware of potential changes in weather patterns and prepare for possible coastal impacts during the elevated high tides, expected to peak in the early afternoon hours of Wednesday.
In summary, the Big Island will experience a mix of weather conditions that includes cloudy skies, scattered showers in some areas, and highs that vary significantly depending on location, with trade winds adding a breezy element to the overall forecast.
