A weak surface trough that brought areas of showers to much of the state the past few days has finally moved west of Kauai. Trade winds will now become fully established and continue through the upcoming week. We will see showers favoring windward and mauka areas, most frequently at night and during the early morning hours. Overall, the next week will be drier for most folks than this past week.
Stable and mostly dry trade wind weather is expected through Monday, with trades increasing a bit more to breezy levels by Monday afternoon. Isolated to scattered showers will continue to ride in with the trade winds, especially over Kauai and windward areas. Showers will be most prevalent in these locations during the overnight through morning periods, which could produce brief MVFR conditions. Otherwise VFR conditions should prevail at area terminals.
AIRMET Sierra remains in effect for north through east sections of Kauai this evening due to some lingering moisture in the area.
AIRMET Tango is also in effect for low-level turbulence downwind of island terrain. This AIRMET will likely be needed through the next several days. In addition, AIRMET Tango has been issued this evening for moderate upper level turbulence over the islands as well. Model guidance indicates that upper level turbulence is expected to largely diminish by Monday morning as the upper jet over the islands weakens and moves farther east.
