Thank you so much, Joseph, for going above and beyond with your incredible hospitality! What an unforgettable way to celebrate my 30th birthday. I'm excited to analyze how ecosystems exhibit resilience under hydrological drought/intensification 🌳 The 3rd picture is supposed to be a tadpole (iykyk)

Winter weather is forecast to impact a large part of the country in the coming days. Will there be snow, ice, rain? NWS Meteorologist Haley Thiem explains how the temperature of the air between the clouds and the ground determine the type of precipitation you get.

A large December storm hit the mountains of the Pacific Northwest – and left snow conditions in the Yakima Basin worse off in its wake. How might this event be a harbinger of winters to come? I offer this perspective piece, published today in @theconversation.com #snow #drought #climatechange
theconversation.com
The western US is in a snow drought, and storms have been making it worse
A major atmospheric river brought record precipitation to the Pacific Northwest, yet the snow and water supply still suffered. It’s a growing problem.
