The disturbance bringing us all of this unsettled weather is just west of Kaua‘i and forecast to move over the islands later today and tonight. The trough is expected to lift away from the state on Thursday. However, spots heavy rainfall will be left in its wake because of southwesterly winds and a humid airmass. Thursday night through Friday we are forecast to get into a more stable and “normal” weather pattern but this will be short-lived. A cold front is forecast for this weekend which will bring increasing chances for rain again.
We have southeast to south winds today around 15 to 20 mph. High temperatures are forecast from 76° to 81°. Mostly cloudy skies are expected for Hawaii County with showers and the chance of heavy rain and thunderstorms. If we get thunderstorms, they could be accompanied by small hail and damaging winds. It’s a developing weather situation and the potential is there. I’ll keep an eye on it.
