Weather Discussion:
Mostly cloudy across south TX this morning, with temperatures in the lower 60’s to mid 70’s.  A
cold front is approaching Del Rio and will move east through the rest of the region today.  
Scattered showers and a few thunderstorms are possible along and ahead of the front today.  
As the front interacts with warmer air later today, scattered to widespread showers and
thunderstorms are likely east of San Antonio.  A few storms east and northeast of San Antonio
could be severe later this afternoon.  The main threat today is large hail and damaging straight
line winds.  Skies look to become mostly clear after the rain passes.  High temperatures in the
lower to mid 80’s, with cooler temps over hill country.  Rain looks to be in eastern TX by sunset,
with mostly clear skies overnight.  Low temps in the mid to upper 50’s, with cooler temps over hill
country and warmer temps near the coast.

High pressure moves into the region on Saturday with mostly sunny skies and highs in the lower
to mid 80’s.  Partly cloudy overnight Saturday with lows in the upper 50’s, lower 60’s.  Partly
cloudy on Sunday with highs in the mid to upper 80’s.  A weak front looks to pass through the
region overnight Sunday, with isolated showers north of San Antonio.  Partly cloudy on Monday,
then a better chance for rain on Tuesday when another front looks to move through the region.
