Wider weather episode

A stalled frontal boundary over the area provided a focus for convection to develop in the afternoon on July 4th. CAPE values of greater than 2000 J/kg and PWAT values near 1.8-2 allowed thunderstorms that developed along the stationary front to slowly drift southward while producing torrential rainfall rates of 1-2 per hour. Some areas saw 1-3 of rain over a 1 to 3 hour period which produced localized flash flooding.
