The system that has been causing the state's recent stormy weather is weakening but still overhead, according to Derek Wroe, a forecaster with the National Weather Service.

Meanwhile, the state's regular trade wind pattern is returning.

Tonight's forecast calls for partly cloudy skies with scattered showers mainly over windward and mountain areas, and the possibility of isolated showers over leeward sections, Wroe said.

"There's still some chance for some isolated, locally heavy showers today but it looks pretty good so far," Wroe said, noting that the greatest chance of thundershowers is in the Big Island's peaks.

If wet weather conditions continue to lift, Wroe said, forecasters may consider lifting the flash flood watch this afternoon.
