Looking Ahead
The disturbance bringing us all of this unsettled weather is just west of Kauai 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.
Today
We have south to southwest winds today around 15 to 20 mph with higher gusts. High temperatures are forecast from 78° to 83°. Mostly cloudy skies are expected for Maui County with the possibility for heavy showers and the chance of thunderstorms as well. If we get thunderstorms, damaging winds and hail are possible. It’s a developing weather situation and the potential is there. I’ll keep an eye on it.
