Short term (today through saturday)... 
an mesoscale convective system/mesoscale convective vortex is slowly dropping south into the Edwards Plateau 
while a weak upper level short-wave is moving northeast into the 
northern Mexican state of Chihuahua. The ongoing showers and 
thunderstorms associated with the mesoscale convective vortex should tend to wane toward 
morning as the airmass stabilizes. The mesoscale convective vortex stalls over western 
parts of south central Texas while the short-wave moves into the 
northern Mexican state of coahuila this afternoon into tonight. 
These two features along with some surface boundaries to interact 
with a moist airmass to generate scattered to numerous showers and 
thunderstorms later this morning through this evening. Some storms 
may produce locally heavy rainfall up to 3 or 4 inches...gusty 
winds and small hail. A few showers and thunderstorms may linger 
overnight. The mesoscale convective vortex will be absorbed by the short-wave by Saturday. 
Isolated to scattered showers and thunderstorms will develop on 
Saturday as the short-wave moves across central Texas. A slight 
cooling trend of daytime temperatures is expected due to clouds 
and rain. 


&& 


Long term (saturday night through thursday)... 
the short-wave moves off to the east Saturday night with isolated 
showers and thunderstorms lingering. An upper level ridge builds 
into south central Texas on Sunday and persists into Tuesday. A 
rain-free period with slightly above average temperatures can be 
expected. By the middle of next week...an upper level trough 
weakens the upper level ridge. Have maintained the slight chance 
of showers and thunderstorms for late Wednesday into Thursday due 
to passage of the upper level trough.
