The combination of a cold front, jet streak, and an upper level low pressure are to our north led to a severe weather outbreak across the county warning area.  Thunderstorms formed over Val Verde County around 1215 to 1230 AM. As the storms moved east they intensified quickly. This was associated with a low amplitude mid to high tropospheric trof coming from the west, from 700 to 200 mb. The storms continued east across the hill country to the Austin and Georgetown areas. As a cold front moved south around 730 to 800 AM, the storms intensified over Williamson, Travis and Northern Bastrop Counties.
