4/1/2010 10:24 PM Very brief hailstorm. Hailstones were between 0.3 and 0.4 inches in diameter (measured with my snow ruler since that's what I had handy). Stones were white ice, but quite hard. Within 2 minutes, the shower turned to softer and smaller graupel pellets. 3/8" 1/4" Pea Size Rice Mixed|White Ice 2 1min Continuous False Same time as rain Before smaller hail 10-20
