Partly to mostly cloudy skies are expected in windward and mauka areas tonight with likely showers in the forecast. Leeward areas should be mostly cloudy becoming mostly clear as the land breeze kicks in and pushes our clouds out to sea. Winds are out of the northeast from 5 to 20 mph. Low temperatures are expected in the range of 66° to 73° with a low of about 49° at 5000 feet.

Rainfall may increase slightly and temperatures may drop slightly Friday and into the weekend. Drier conditions are expected Sunday. Winds are forecasted to shift and become light and southerly ahead of a front expected in the Wednesday / Thursday time frame.
