Looking Ahead

A low pressure disturbance moving through the region continues to drive rain showers eastward across the state today. Moderate to heavy showers over the western islands led to elevated stream levels on Kauai and Oahu with some reports of flash flooding this morning. These convective showers will move into Maui and Hawaii County later today with periods of heavy rainfall and the potential for a few thunderstorms. Strong winds aloft are reaching the Big Island summits coupled with snowfall and low visibilities will produce treacherous wintery conditions at the highest elevations. Drier air will move into Kauai later this morning and Oahu this afternoon with improving weather conditions pushing eastward across the entire state on Sunday. Wind speeds will become light and trend towards land and sea breezes for the first half of next week. Trade winds returning with isolated to scattered windward and mauka showers by Thursday.
