What happened

The episode as NWS DMX wrote it up.

Thunderstorms developed early in the morning ahead of an approaching warm front. Very little in the way of severe weather occurred with them, however dime size hail was reported during the initial development stage. The main problem was the heavy rainfall that occurred on saturated ground. Urban flooding was reported as one to two inches of rain fell in one to one and one half hours time. This caused some property damage.
