A front, which has been lingering north of our area, marched south on July 6th and brought damaging storms and widespread flooding.   Sufficiently strong mid-level flow supported damaging wind in some cases. However, the main impacts were from flash flooding.  This was supported by the presence of anomalously high precipitable water values, deep warm cloud depths, and sufficient instability and lift.
