Puna Weather

Friday 6th December 2024

Today through the upcoming weekend mostly dry with light to moderate easterly Trade winds.

Monday and Tuesday scattered showers with moderate to breezy east-northeast Trade winds.

The ridge overhead that has supported the dry weather of late is weakening over this weekend. An upper level trough approaches from the north lifting and weakening our inversion layer for thicker clouds and better shower coverage on Monday and Tuesday.

Another upper level trough dives south pinching off a closed low to our southeast. This feature has good dynamics and a decent cold pool aloft. The low is long lived and develops a surface reflection, which eventually heads towards our island bringing the threat of heavy rains and strong winds. It looks a little like a Kona low, but to our east instead of to our west... not a typical scenario. If this comes to pass the wet weather would likely begin around December 14th. This is a long ways off and I wouldn't normally lean into it this early, but other models, notably the Euro, show a nearly identical solution.
