An upper level ridge dominated the upper air pattern over the Western United States with weak flow over the Borderland. A surface convergence area was setup near the Rio Grande Valley with sufficient moisture in place to produce thunderstorms across the region. One of these storms produced a quick inch of rain around Hill which lead to some localized flash flooding.
