Puna Weather
Wednesday 18th February 2026
Today and Thursday moderate easterly trade winds with widely scattered showers, mostly during the night and early morning.
Friday through Monday light to moderate easterly trade winds with scattered showers, possibly heavy at times. Some thunder is possible through the period and the snow level should hover around 11,000', possibly lower in heavier snow showers.
A ridge is overhead today into Thursday (1st 500mb chart) supporting an strong inversion over us and limiting showers.
Friday through Monday an upper level trough is right over us (2nd 500mb chart) with cold air for thick clouds and some instability. Since yesterday models have made some adjustments and the trough aloft is now forecast to be a little stronger, which places us under westerly flow aloft (skew-t), and on the drier side of our mountains. Models also show some mid-level drier air getting wrapped into the circulation beginning Sunday further limiting rainfall potential.
All in all expect some showers and maybe a good thunderstorm.
