A disturbance high in the atmosphere has created instability that led to snowfall on our Big Island summits yesterday. This feature will remain just south of the islands through Friday. Breezy trade winds will give way to increasingly moist southerly flow over the state. The combination of these two features will cause pockets of heavy rain and even a few thunderstorms over and near the state for the next few days. The disturbance is forecast to move away from the islands on Monday with the airmass drying out somewhat at that time.
Mostly cloudy for windward spots with frequent showers. Hazy for the Kona side with scattered showers. Locally heavy rainfall possible with a slight chance of thunderstorms. High temperatures from 78° to 83°. Winds will be out of the northeast around 15 mph.
UV index at 6 (“high” exposure level)
Winds will be variable around 15 mph. Mostly cloudy with likely showers in windward spots. Scattered showers for leeward areas. Chance of thunderstorms and locally heavy rainfall possible. Low temperatures from 68° to 73°.
