NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
1243 PM CDT sun Jul 5 2015 


Update... 
please see the 18z aviation discussion below. 


&& 


Aviation... 
cloud bases continue to rise early this afternoon with daytime 
heating. Currently all sites are VFR and this is expected to 
continue through this evening. A few showers remain possible this 
afternoon and early evening. These showers will be brief and coverage 
will be isolated...so will not mention in the aviation forecast at 
this time. Otherwise...gusty south winds are in store through the 
early evening. Winds should begin to ease through the overnight 
hours as low clouds develop. We/ll continue to mention MVFR ceilings 
developing along I-35 around 07z...with ceilings dropping into IFR 
around 10z. Out west at kdrt...MVFR ceilings are expected around 10z. 
Improving conditions are expected late in the forecast period as 
ceilings rise. 


&& 


Previous discussion... /issued 1114 am CDT sun Jul 5 2015/ 


Update... 
a few showers have developed during the late morning as skies have 
begun to clear over south central Texas. While the atmosphere is 
modestly unstable and isentropic lift across the eastern County Warning Area are 
sufficient to initiate some showers...laps/RUC soundings continue 
to indicate capping and a freezing level of about 14kft. Precipitable water 
values are only about in the 1.3-1.5 range as well. Ttu WRF hi res 
model seems to handle this accurately...with just stray shower 
development this afternoon and dissipating quickly by the end of 
diurnal heating. Not expecting anything hazardous but did increase 
probability of precipitation to slight chance across the east. 


Also...morning cloud coverage resulted in the hourly T trends to 
be a bit too aggressive...blended current observation into the trend to 
correct.
