Puna Weather

Saturday 18th October 2025

Today through most of next week periods of scattered windward showers, some brief downpours are likely. Thunder looks unlikely and freezing level should remain above our mountain tops.

A low aloft to our west had weakened our inversion for better shower coverage the past couple of days. This upper level low exits to our west as a new one approaches from the northeast (500mb vorticity animation). During this period light to moderate easterly trade winds push moisture (moisture anomaly animation) up our mountains, providing lift. The combination of trade winds, moisture, and some dynamics add up to bring some much needed rain over the next 5 to 7 days.
