NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
401 am CDT Friday Aug 29 2014 


Short term (today through saturday)... 
regional radar images are showing two distinct areas of convection 
this morning. One of the areas is located across central Texas 
pushing to the southeast associated with a surface trough. This 
feature is the reflection of a middle-level trough axis pushing 
across the Southern Plains. The second feature is just offshore 
from deep south Texas. These two features will combine later this 
afternoon and evening to produce scattered showers and 
thunderstorms mainly along and east of Highway 281. With precipitable waters  
near 2 inches across the southeast counties...can't rule out heavy 
rain/localized flooding. Also... local soundings suggest gusty 
winds of 40 to 50 miles per hour with any strong thunderstorm that does 
develop. Some lingering showers and thunderstorms may affect The 
Hill Country and far southeast part of our County Warning Area during the evening 
hours before much of the activity comes to an end. For 
Saturday...scattered showers and thunderstorms are anticipated 
along and east of Interstate 35 as the upper level trough slowly 
exits the local area and pushes to the southeast. Heavy rain is 
possible once again across the coastal plains including the far 
southeast counties as precipitable waters  remain near 2 inches. 


&& 


Long term (saturday night through thursday)... 
a zonal flow is expected to control the weather pattern for the 
extended period with only sea-breeze type convection across the 
southeast counties during the afternoon period from Tuesday 
through Thursday of next week. Temperatutes will be slighly above 
normal averages with highs in the middle to upper 90s and lows in the 
middle to upper 70s.
