Discussion
The upper air sounding this afternoon depicts a dry and stable profile as a mid-level high pressure dominates in the area. This feature will suppress any deep convection that attempts to develop. As a result, conditions remain generally fair with only passing showers embedded within the trade wind flow. Latest satellite trends supports the sounding, showing fair weather cumulus across the islands with no organized areas of convection nearby. Model guidance indicates little change in the overall pattern, with the mid-level ridge expected to persist through the new week.
At the surface, moderate easterly trade winds will continue, ranging from 10 to 15 mph. These trades will help maintain stable conditions while carrying brief, passing clouds at times. Overall, expect fair weather through the upcoming week, with limited rainfall potential.
Marine
Latest wave heights at the Aunu'u PacIOOS buoy are around 5 to 7 feet. Light to moderate easterly winds near 10 mph are producing somewhat textured seas, but overall marine conditions remain fairly calm. Seas are expected to remain in the 5 to 7 foot range through the new week, with only minor fluctuations. No significant winds or swells are anticipated during the forecast period.
