Mean Green

TOP IMAGE: A shelf cloud approaches from the southwest along a strong gust front around 5:33 PM, CDT Friday, June 29, 2012 as seen from the protective front entrance overhang at Noelridge Christian Church in Cedar Rapids, Iowa. The leading clouds took on a greenish-gray appearance as they plowed through and gobbled up temperatures in the mid-80s with dew points in the upper-60s. MIDDLE IMAGE: A base wind velocity capture taken of the area at 5:32 PM. Blue areas show 60-80 knot wind speeds, with green indicating 50 kts. or less. The white "X" at top shows the relative position of the camera. BOTTOM IMAGE: No apparent damage took place around my spotter's position at the church, but about an hour later back at home I discovered that a medium-sized branch had fallen on our roof (the only such damage for blocks) and had, ironically, disabled my roof-mounted weather station, breaking off the wind vane and anemometer arm!
