Oregon is in snow drought. Oregon State Climatologist @larryoneill.bsky.social discusses how much snow the state needs to avoid potential water shortages. capitalpress.com/2026/01/05/o...
Oregon sees snow shortage to start 2026, storm won’t solve problem | Capital Press
Oregon’ snowpack was poor to start the new year and while a significant storm the first week of 2026 could help, it won’t solve the shortage.

State climatologist @larryoneill.bsky.social explains why atmospheric rivers may become more common in a warming climate. www.opb.org/article/2025...
As climate changes, the PNW could experience stronger and more frequent atmospheric rivers
As the climate changes, atmospheric rivers hold more moisture, and that means more rainfall, according to Oregon's climatologist.
