NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
311 am CDT Wednesday Aug 20 2014 


Short term (today through thursday)... 
showers and thunderstorms have dissipated across the western 
counties and am not expecting much in the way of additional 
activity. The upper tough/shear axis responsible for the 48 hours 
of activity has weakened and lifted to the northeast. There is a 
slight chance of sea breeze showers and thunderstorms across the 
coastal plains counties this afternoon. Precipitable water values then drop off 
and will keep a dry forecast across all of south central Texas on 
Thursday. Highs today and Thursday will be persistent...in the 
upper 90s to near 100 degrees for much of the area. 


&& 


Long term (thursday night through tuesday)... 
a mostly dry forecast will continue through Sunday. Moisture will 
remain rather sparce and this should limit the activity. Cant 
completely rule out a stray shower on any given afternoon...but 
the chances were too low to mention at this time. Precipitable water values 
increase to near 2 inches across the southeastern counties on 
Monday and this should be sufficient to warrant a mention of 
thunderstorms in this area Monday. Models are showing this 
increase in moisture to be short lived with precipitable water values returning to 
below 1.8 inches Tuesday. Temperatures in the extended will 
continue to be persistent with highs in the upper 90s to near 100 
degrees and lows in the middle to upper 70s across much of the 
area.
