Windy Balloon Launch: 7/17/18

On Tuesday, July 17th decaying thunderstorms to the northwest of Grand Junction produced gusty outflow winds across the Grand Valley. The Grand Junction Regional Airport measured a peak wind gust of 70 mph at 4:10 PM MDT! Those strong winds persisted over the next hour and, by the time we sent up our weather balloon at 5:00 PM gusts were up to 58 MPH. Weather balloons are launched at various locations all across the world twice a day, every day, under a wide variety of conditions. We won't launch if there's lightning nearby but otherwise it's fair game! Check out the video of the balloon launch below!
