NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
657 PM CDT sun Aug 28 2016 


Aviation... 
some showers are currently passing over aus and storms are 
approaching and will likely affect drt over the next 2 hours. Once 
the sun GOES down am expecting the convection to decrease with the 
overnight hours mainly dealing with light NE surface winds and 
debris clouds. Look for areas of MVFR ceilings again in the 
morning hours across the aus/ssf/Sat taf sites. A little less 
likely out in drt. By 16-17z Monday the ceilings should improve 
and the return of scattered clouds and vcsh will dominate. The low 
pressure area near the Upper Texas coast will continue to bring just 
enough moisture into the area to get scattered sh/ts with 
afternoon heating. Not out of the question in getting some ts to 
affect the sites Monday PM but too early to try and give any 
specific timing details.

Previous discussion... /issued 639 PM CDT sun Aug 28 2016/ 


Update... 
cluster of thunderstorms across Val Verde, Kinney, and Edwards 
counties are showing signs of producing outflow boundaries well 
ahead of the precipitation cores which should serve to begin a 
downtrend in intensity over the next hour or so. As we lose 
daytime heating influences by 01-03z, the rest of the activity 
across south central Texas should wane in coverage and intensity. 


Have increased pops and quantitative precipitation forecast for southeastern Val Verde, western 
Kinney, and northern Maverick counties through the next 3 hours as 
well as hourly T/TD updates based off latest hourly obs. 


Previous discussion... /issued 255 PM CDT sun Aug 28 2016/ 


Short term (tonight through Monday night)... 
the latest water vapor loop shows an upper low over the 
northwestern Gulf/far southeast Texas this afternoon. This upper 
low will be the main weather feature of interest for the next 
several days. With the upper low in proximity to the region, we 
will continue to see above normal moisture levels. This moisture 
along with daytime heating will lead to isolated to scattered 
showers and thunderstorms through this evening. Most activity will 
be tied closely to daytime heating, so a decreasing trend in 
shower and thunderstorm activity is expected by late evening. Some 
locally heavy rainfall is possible, especially given the slow 
storm movement. For tomorrow, a similar pattern is in store as we 
continue to see an increase in deep layer moisture due to an 
increase in easterly flow in the lower and mid-levels. While most 
convection will likely occur in the afternoon and evening hours on 
Monday, we can't rule out some overnight showers due to the 
increase in moisture. 


Long term (tuesday through sunday)... 
the above mentioned upper low will drift southwestward into the 
middle Texas coast on Tuesday. With plenty of moisture in place, 
we expect another round of diurnal showers and thunderstorms 
across south central Texas. The upper low will weaken while 
moving southwestward into south Texas on Wednesday. The atmosphere 
will begin to slowly dry for the remainder of this week as the 
deeper moisture moves into south Texas. In addition, mid and upper 
level ridging along with the decrease in moisture will result in a 
decreased chance for rain. Temperatures will also begin to edge 
upward for late this week into early next week. However, given the 
recent rains and moist ground, we expect near or just below normal 
high temperatures along with normal overnight lows.
