Last Updated on Sunday, 10 January 2010 00:03 Written by Roger Hill
April 18 was my favorite chase day of the year. A dryline/front intersection (triple point) was the focus for intense convection this day. I arrived north of Wichita in time for the first cb to go up. It died quickly as other towers also tried in vain to break the cap. Finally by late afternoon a storm broke the cap and went on the be the most scenic supercell of the year. It moved slowly across McPherson county, Kansas as it became a gorgeous "upside down wedding cake" with intense cg, hail and a couple of tornadoes.
