EMPLOYEE OF THE MONTH TOUR WEATHERMAN - STEWART WILLIAMS Golf Magazine May 2001 As a Weather Channel meteorologist, I watch the skies for the PGA Tour wherever each week's event is being played.  I arrive on Tuesday to set up before Wednesday's pro-am, and stay on-site each day from 6 a.m. until the final group signs its scorecard. I'm usually hidden from view, sharing a construction trailer with the Tour's communications staff.  With two laptops, one connected to satellite pictures, the other to the National Lightning Detection Network, and our Thorguard lightning prediction system [pictured], I can track weather disturbances nationwide.  I anchor Thorguard to the roof of the trailer, and its sensors pick up electrical charges in the clouds and on the ground.  The receiver tells me the chance of lightning within 12 miles, and the chance within two miles.  As the percentages rise, I update Tour officials.  By the time there's an 80 percent chance of lightning within 12 miles, play has been suspended.  The Tour gives people at least 30 minutes' notice before a storm hits to seek shelter. So what do I do on clear, sunny days?  I get out, walk around, and watch some golf.  But I don't stray too far - just in case.
