NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
246 PM CDT Sat Aug 1 2015 


Short term (tonight through Sunday night)... 
daytime heating working on deeper moisture with precipitable waters  of 1.6 to 1.8 
inches has allowed isolated showers and thunderstorms to develop 
over the Edwards Plateau this afternoon. This deeper moisture will 
slowly erode this evening as a drier airmass with below normal precipitable waters  
of 1.2 to 1.6 inches continues to filter in from the east. Expect 
showers and thunderstorms to dissipate a little after sunset with 
loss of daytime heating and the drier airmass. 


For Sunday...the subtropical ridge remains from the southwestern 
states into the Southern Plains. Strong subsidence underneath the 
ridge and below normal moisture levels will not allow for rain. 
Daytime temperatures continue to be slightly above normal with 
some highs around 100. Heat index values will be near or just 
above actual temperatures as drier air aloft mixes to the surface 
during the daytime hours. 


&& 


Long term (monday through saturday)... 
the Sunday pattern continues next week into next weekend with no 
rain expected and slightly above average daytime temperatures. 
Lower level flow off the Gulf of Mexico strengthens by middle week 
increasing humidity levels allowing for heat index values above 
105 during the afternoon hours southeast of I-35 and in spots 
along the Rio Grande. 


The only potential for any rain may be from an old surface 
boundary currently in the Gulf of Mexico that moves onshore to 
generate some showers and thunderstorms. Most models dissipate 
this boundary over the Gulf with no impacts to south central 
Texas.
