Boulder - About 100 volunteer weather observers -- the people who measure temperature, gauge rainfall and snow depth, and check for severe weather -- will receive special recognition in Boulder on April 21.

This will also be a day of briefings and tours. Dr. Thomas Schlatter, of NOAA’s Forecast Systems Lab, will talk about Rocky Mountain Weather. Dr. Erik Rasmussen, of NOAA’s National Severe Storms Lab, will share his scientific experiences as a tornado chaser. Visitors will also tour the Space Environment Center. Helping to build the event are Cooperative Program Managers at Colorado weather forecast offices in Boulder/Denver, Grand Junction and Pueblo and Cheyenne, Wyoming and Goodland, Kansas. NOAA is hosting along with the National Center for Atmospheric Research and the Colorado Climate Center at Colorado State University. http://coco-rahs.fsl.noaa.gov/weatherworkshop/
