Puna Weather
Tuesday 24th March 2026
Today moderate to breezy northerly winds with widely scattered showers this morning and possible thunderstorms, with periods of heavy rain, this afternoon and evening.
Wednesday moderate to breezy northeast winds with widely scattered showers mostly during the night and early morning hours.
Thursday through Sunday moderate to breezy northeast winds and mostly dry. Progressively colder nights through the period.
Our Kona low is now to our east, but residual moisture remains in place over the region. Also in place today is colder air aloft. As such there is again a chance for afternoon thunderstorms.
The departing Kona low will place us under increasingly dry and stable northerly flow beginning later tonight, with dew points dropping into the upper 50s this weekend. This will make for dry weather and chilly nights.
The MJO is in a active phase and currently traversing the Pacific basin. With much warmer than normal sea surface temperatures from the dateline west, tropical activity is forecast to be higher than normal. Long range model runs are keeping a jet stream branch over the tropical central Pacific for a couple of week. This creates too much shear (shear chart) for any tropical lows to form, and by the time the jet lifts north (2 weeks or so) the MJO pulse will be continuing towards Africa. Nonetheless a tremendous amount of rain is in the forecast (Rain chart).
