I’ve been a “weather geek” since I was young child. I joined the military out of high school and was lucky to get my dream job in weather. I have 20 years of military weather experience which includes forecasting the weather all over the world. Highlights were six years in Alaska and making life and death weather decisions during deployments. I love mountains, I love snow, and I love summertime thunderstorms. I spend a bunch of time playing outdoors and found my paradise in Pagosa Springs. I do Pagosa Weather as a community service. Hopefully you find us helpful!

  1. Blondie from Blondie’s Fruit and vegetable stand east of town said it always snowed on September 10th in Pagosa Springs for the last 10 years. The snow would not stick to the ground. As an avid gardener I have kept an eye out for on freezing temps before they happen so I can pick my tomatoes before a freeze. We are experiencing amazingly warm weather for our area and I am very grateful!
