About Meteorologist Jim Woodmencey

Jim started MountainWeather™ in 1991 after many years of working outside in the weather, climbing and skiing! Here is his story in brief............

Jim graduated with a B.S. in Meteorology from Montana State University in Bozeman in 1982. While attending college in the late 70's and early 80's Jim worked as a mountain guide in the summers out in the Cascades of Washington for the American Alpine Institute, teaching climbing, and guiding peaks in the Cascades, and Alaska.

Immediately following college graduation he went to work for the National Park Service in Grand Teton national Park, where he spent 14 summers as a Climbing Ranger, and received the Department of the Interior Valor Award for a rescue on the Grand Teton in 1985.

During the Winter of 1985-86 he worked as an avalanche forcaster and meteorologist for the Alaska Avalanche Forecast Center in Anchorage. Following this brief foray to the north, he returned to the Tetons and continued working in the summer as a Ranger and in the winters as a ski-guide for High Mountain Heli-Skiing. (Jim "retired" from heli-ski guiding in 2008 after 20 seasons.)

Jim's work with the heli-ski operation is what prompted him to buy his first computer and forecast the weather for them from his own office starting in 1991. A heli-ski operation is a very weather dependent business, and better forecasts not only increase revenue, but also safety. Word of the forecasting he did for the heli-ski operation spread through the ski community of Jackson Hole and it wasn't long after that weather forecasting became a full-time endeavor.

Jim began his first broadcasting job with a local radio station in Jackson Hole in 1993 and has done a "live" morning radio show featuring his weather forecast for the Jackson Hole area for over 22 years.

While still climbing, mountain biking, hiking, and skiing recreationally, Jim's local weather forecasting duties, and maintaining the content on this website, consume his weekly work schedule.  Everyday Jim draws on the experience he has had working in the mountains to make a better forecast of the weather in mountains. In addition to organizing and teaching a variety of weather courses throughout the year.

Jim has authored two books, Reading Weather, published by Falcon Guides in 1998  & Weather in the Southwest, published by Southwest Parks & Monuments Association in 2001.

Jim completed an educational project through UCAR (University Corporation for Atmospheric Research), writing the content for an online module for COMET® (Cooperative Program for Operational Meteorology, Education and Training) entitled Avalanche Weather Forecasting, which is now available on-line for viewing on-line. See the module at this link: COMET Avalanche Weather Forecasting Module.

Most recently, in 2014 Jim became part of the adjunct faculty at Alaska Pacific University in Anchorage, teaching a weather course through the Enviromental Sceince and Outdoor Studies programs, as well as working on a senior project advisory committee.

Jim is a member of the American Meteorological Society (AMS), and a professional member of the American Avalanche Association (AAA), as well as a Certified Avalanche Instructor.
