An upper-level trough will bring increased high clouds and renewed chances for isolated heavy showers and thunderstorms this afternoon and Monday. Light winds favor chances for mainly afternoon showers Tuesday and Wednesday, followed by rebuilding trade winds Thursday and Friday.

Predominately light northeasterly winds among some land-sea breezes will remain in place through the next several days under high pressure well northeast of the Hawaiian Islands and a surface trough lingering to the west. Some terminals may experience some mid- to high-clouds and embedded light showers, resulting in brief periods of MVFR conditions. Otherwise, expect VFR conditions to prevail across most terminals through the period.
No AIRMETs in effect.
A trough approaching slowly from the west will allow winds to veer east southeasterly and weaken later today through early next week across the local waters. This feature will also bring a slight chance of thunderstorms to the waters surrounding Kauai this afternoon through mid day Monday. By Thursday, high pressure ridging builds back in north of the state with fresh easterly trade winds returning to the region lasting through next weekend.
Swell, from every direction, and surf will remain very small through late Monday. A small, medium period, northwest swell will move into the region by Monday night and continue through Wednesday. A moderate, medium period northeast swell arrives Tuesday and peaks on Wednesday, bringing moderate surf to north- facing shores, before slowly declining through the end of the week.
A series of overlapping small south swells will move into the region this week keeping surf heights on the small side. Surf heights along east facing shores also remain small due to weaker trade winds until the arrival of the small medium period northeast swell building into the Hawaii region from Tuesday through Thursday.
None.
