Puna Weather
Thursday 2nd October 2025
Today through most of Saturday mostly dry with light to moderate easterly trade winds.
Late Saturday into early Sunday widely scattered showers.
Sunday and Monday mostly dry with light to moderate easterly trade winds turning to northerly and becoming light by Tuesday.
Wednesday through Friday windward showers increase from isolated to scattered through the period with light winds becoming moderate from the east.
A ridge aloft is keeping our atmosphere pretty dry and stable through the weekend. Despite the stable conditions, a narrow band of moisture approaches from the northeast (satellite image), and is likely to generate a few showers late Saturday into early Sunday.
The ridge aloft exits to our west early next week as an upper level trough sets up to our northwest beginning mid-week (200mb chart). This feature draws some tropical moisture up from the south and also lifts our inversion to nearly 10k ft. As soon as the easterly trades return, around Thursday or Friday the components are in place for windward showers (moisture, a lifted inversion, orographic lift).
The upper level trough lifts off to the northwest towards the end of next week ushering in a change in the weather, as models indicate a strengthening subtropical high to our northeast and an extended period of moderate easterly trades over us (surface winds animation), most likely leading to scattered windward showers.
