Ringed by developing thunderheads

This was the view looking west from our house this evening, across to the Loch Lomond and The Trossachs National Park. The atmosphere is very unsettled here just now and the city of Stirling appears to be ringed tonight by fast-growing cumulonimbus thunderhead clouds. All very dramatic but no thunder and lightning yet. I pieced together this panorama using MS Live Essentials Picture Gallery's panorama stitching tool.
