NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
328 am CDT Friday Aug 1 2014 


Short term (today through saturday)... 
cold front has sagged south to near the coastal plains extending 
to the Rio Grande plains and serranias del burro of Mexico. A 
northwesterly flow aloft will allow weak upper level short-waves 
to drop to the southeast along the Rio Grande. Ample moisture 
with precipitable waters  up to 2 inches will be lifted by the frontal zone and 
short-waves to generate isolated to scattered showers and 
thunderstorms across the Rio Grande plains to the coastal plains. 
Drier air filtering into the eastern Hill Country to along the 
I-35 corridor northeast of San Antonio will keep rains out of 
those areas. Clouds and rain will allow for below average 
temperatures. 


&& 


Long term (saturday night through thursday)... 
an upper level ridge over The Rockies and an upper level trough 
over the eastern states makes a northerly flow aloft drying the 
airmass with precipitable waters  falling below 1.5 inches Sunday into Monday as 
the front dissipates. The upper level ridge slowly builds east 
Tuesday through Thursday as the upper level trough fills. Rains 
are not expected Sunday into the middle of next week. Although... 
can not rule an isolated shower or thunderstorm near the coastal 
plains Sunday and Wednesday. An easterly wave per the European model (ecmwf) moves 
west under the ridge generating isolated showers and thunderstorms 
east of I-35 on Thursday. A slow warming trend is expected as the 
ridge becomes more dominant leveling off by the end of the week 
due to the easterly wave.
