Weather Discussion:
Mostly cloudy over the south TX region this morning, with scattered showers and thunderstorms
east and southeast of San Antonio.  These storms are from a much larger complex of storms
which is slowly moving off to the east.  More showers and storms are still redeveloping east of
San Antonio, and look to last through the mid to late morning hours before moving out over the
Gulf.  With the abundant moisture in place, isolated to scattered showers and storms look
possible across the region later this afternoon.  Mostly cloudy with high temperatures in the
upper 70’s, lower 80’s with cooler temps over hill country.  Mostly cloudy overnight with isolated
showers in the evening.  Overnight lows temps in the upper 60’s, lower 70’s with cooler temps
over hill country.  Fog possible in the overnight hours.

Isolated showers and thunderstorms are possible again on Tuesday, but the development of
rain will likely depend on the sun coming out and warming up the ground.  Tuesday high temps
in the mid to upper 80’s with cooler temps over hill country.  Mostly cloudy overnight Tuesday
with isolated showers and storms possible over hill country, and patchy overnight fog.  Tuesday
lows in the lower to mid 70’s.  Another low pressure system looks to move across the region on
Wednesday, with scattered to widespread showers and thunderstorms.  Some storms could be
severe and produce heavy rainfall.  Wednesday highs in the lower to mid 80’s with cooler temps
over hill country.  The low pressure system slowly moves off to the east on Thursday with more
showers and storms.  Mostly cloudy on Friday.
