.SHORT TERM (Tonight through Saturday Night)... A weak upper level
shortwave will move into Texas tonight bringing a chance for
thunderstorms to the Rio Grande Plains after midnight. The feature
will move across to the east Friday and spread a slight chance for
thunderstorms as far east as Kerrville and Hondo. An upper level low
will move into the Southern Plains Friday night and bring a frontal
system across Texas. A warm front will move across our CWA from west
to east followed by a cold front Saturday. This system will bring
chances for thunderstorms Friday night through Saturday night with
the best chances during the afternoon Saturday over the eastern half
of the CWA. Models have continued to trend drier with this system
and rain amounts should be moderate. There is still a slight chance
that some storms could be strong to severe and produce large hail and
strong winds, but this is also looking less likely.

&&

.LONG TERM (Sunday through Thursday)...
Starting Sunday an upper level ridge will build over the Southern
Plains. This will bring dry weather and warming temperatures through
Tuesday. A series of shortwaves will move through the upper level
northwesterly flow during the middle of the week producing slight to
low end chance POPs. The strongest of these will be Thursday and rain
chances will spread across most of the CWA.
