The episode as NWS ABQ wrote it up.
An upper level high pressure system shifted westward centering over portions of Utah and western Colorado. With sufficient moisture as well as instability, storms initially developed over northern portions of the state during the afternoon hours. These storms increased in coverage into the early evening with general storm motions toward the west and southwest. The thunderstorms, though not severe, did produce significant amounts of rainfall in very short time durations. This led to flooding of the Las Conchas Fire burn scar as the storms moved from north to south covering the entire burn scar.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Albuquerque, NM wrote its last area forecast discussion before the first event at Jul 11, 1:48 PM MST, 2 hours 12 minutes earlier.
