NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
623 am CDT Monday Aug 3 2015 


Aviation discussion...for 12z taf period... 
VFR to prevail for the next 24 hours as little to no changes were 
observed since the last forecast package. Towards the end of the 
taf period...some minor cloud cover could impact the i35 terminals 
but think moisture will be insufficient to result in a category 
change. 


&& 


Previous discussion... /issued 256 am CDT Monday Aug 3 2015/ 


Short term (today through tuesday)... 
currently...the County Warning Area is between two areas of scattered rain and 
this will continue for the remainder of the day. To our southeast 
is a coastal trough and precipitable water values between 2.2 and 
2.5 inches just off the coast. There is a sharp moisture gradient 
to the northwest and precipitable water values in our southeastern counties are 
expected to remain below 2 inches. Cant completely rule our a 
stray shower making it to our southeastern counties but the vast 
majority of this activity will remain closer to the Gulf of 
Mexico. Will carry a 10 pop across the southeastern counties but 
will not mention and showers in the official forecast. 


Low-level lift is providing the focus for shower activity well to 
our northwest and this will also not impact our area. The upper 
ridge remains flat and not well-defined as a trough is currently 
moving onshore near California. High-temperatures today will be 
similar to yesterday and surface winds will remain out of the 
southeast and be around 10 to 15 miles per hour...slightly increasing dew 
points. Heat indices will remain below 104 degrees area wide. 


For tomorrow...the ridge axis will begin to strengthen to our 
west...and will have an influence on our weather as highs could 
be a degree or two warmer than today. Models show some potential 
for sea breeze activity well to our east and will not mention 
anything in the forecast. 


Long term (tuesday night through sunday)... 
the ridge to our west will continue to strengthen on Wednesday and 
temperatures will continue to respond with near 100 degree 
temperatures expected for much of the County Warning Area. By Thursday and 
Friday...the ridge will slightly shift east and will have more of 
a hold over Texas. 850 temperatures are expected to increase as 
subsidence aloft increases and high temperatures will likely be 
near or above 100 degrees for much of the area Thursday-Sunday. 
Will have to watch surface moisture closely during this time frame 
as our western and southern counties will be close to heat 
advisory criteria. Will go ahead and begin to mention the elevated 
heat once again in the severe weather potential statement. With strong subsidence rain chances 
will be near zero during the long- term forecast.
