/ISSUED 332 AM HST Fri Jan 6 2023/
Radar shows very little shower activity this morning, while satellite loop shows mostly clear skies across the smaller islands. Scattered to patchy broken cloud cover persists over windward and southeast facing areas of the Big Island. Expect isolated to scattered showers across windward areas of the Big Island this morning, with dry conditions elsewhere. By this afternoon, PW values below an inch will move in as inversion heights continue to lower to 5,000 feet or less. Little shower activity is expected statewide as very dry air spreads to all of the main Hawaiian Islands.
A surface ridge will remain nearby through Tuesday. Expect very little change in the overall weather pattern, with mostly dry conditions and light to moderate trade winds. Models show a weak front could approach Kauai and Oahu by the middle of next week, potentially increasing showers for the western islands. Light and variable winds may occur on Tuesday in advance of this front, with perhaps a return of light to moderate trade winds for Wednesday.
