Several thunderstorms developed along a stalled frontal boundary near Parker, Wise, and Cooke County. The environment was very unstable with a very dry airmass in the lowest 10 thousand feet of the atmosphere. This set up was perfect for very strong and localized microbursts, and several microbursts occurred in Cooke County. The most significant damage occurred in the town of Muenster. Later in the evening, a heatburst occurred in Tarrant County from light rain falling from a decaying thunderstorm into the very dry airmass. Winds around 70 mph were measured from this heatburst.
