Puna Weather
Wednesday 8th October 2025
Today through Friday light winds and only widely scattered showers.
Saturday and Sunday light to moderate easterly trade winds with a few more showers likely.
Late Sunday and Monday moderate easterly trade winds with frequent windward showers, some of which could be heavy at times.
An upper level low to our northwest (500mb chart) is interrupting our trade winds, placing us in light southerly flow aloft. This pattern may bring some showers to our southern shores, but despite the southerly flow, low level moisture is limited.
The upper level low weakens and exits the region as we head into the weekend allowing surface high pressure to become established to our north for a return of easterly trade flow (surface animation).
Enhanced low level moisture approaches from the northeast (moisture anomally animation) some time Sunday, likely later in the day, for a significant bump in rain, likely to last, off and of, through much of next week, as it is coupled with a weakening and lifting of our inversion layer to as much as 15,000' at times. DCAPE looks to remain below 1,000J/kg, so thunder is currently looking unlikely. Nonetheless, this looks like a good scenario for an extended period of wet trades.
