NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
725 PM CDT Tuesday Sep 2 2014 


Update... 
based on current radar trends...we have sent a quick update to the 
forecast to expand rain chances into the western Hill Country. We 
still expect a decreasing trend this evening...but can/T rule out 
mainly isolated convection over the next couple hours. Minor 
changes have also been made to the sky cover...winds and dew 
points to account for the latest observational trends. 


&& 


Previous discussion... /issued 642 PM CDT Tuesday Sep 2 2014/ 


Aviation... 
isolated to scattered rain showers will dissipate by 02z and have no effect on the 
taf sites. Expect a repeat tonight of the past few nights with 
MVFR stratus developing around 07z at the I-35 sites and 10z at 
kdrt. MVFR should last until 16z and then lift to VFR ceilings. The 
I-35 sites should have scattered clouds after 20z...but also a prob30 of 
thunderstorms and rain from 20-24z. Winds will remain southeast and become 10g22kt 
at 16z for kdrt...and after 20z at the I-35 sites. 


Previous discussion... /issued 326 PM CDT Tuesday Sep 2 2014/ 


Short term (tonight through Wednesday night)... 
Tropical Storm Dolly will make landfall in northeastern Mexico 
this evening. A southeasterly flow has allowed a deeper moist 
airmass with precipitable waters  near 2 inches to move inland across the coastal 
plains. Widely scattered and an occasional thunderstorm have 
developed along and east of I-35. These will continue to move to 
the northwest before dissipating this evening by a little after 
sunset. As Dolly moves further inland and weakens...this deeper 
moisture spreads further west across south central Texas. Expect 
showers and thunderstorms to develop early in the morning near the 
coastal plains and then spread west across the area during the day 
with dissipation most areas by sunset. Coverage will be scattered 
in the south and become much more isolated in the north closer to 
subtropical ridge. Locally heavy rainfall is possible due to precipitable waters  
near 2 inches. Have maintained low chance probability of precipitation Wednesday night 
mainly across the Rio Grande plains due to upslope flow enhancing 
lift and closer proximity to the nighttime rains associated with 
the center of the remnant low of Tropical Storm Dolly. A slight 
cooling of highs is expected across southern parts of our area on 
Wednesday due to more clouds and rain. 


Long term (thursday through tuesday)... 
Thursday into Friday...the remnant low of Dolly will dissipate. 
However...moisture levels are slow to decrease as the subtropical 
ridge becomes more dominant. Isolated to scattered are expected 
during the daytime hours...retreating to the Rio Grande plains 
Thursday night and Friday night. Saturday through Monday...the 
subtropical ridge settles over our area. Isolated showers and 
thunderstorms are possible along the seabreeze near the coastal 
plains. In addition...on Sunday...a weak surface boundary briefly 
moves into central Texas. Isolated showers and thunderstorms are 
possible across our northern counties. By Tuesday...the boundary 
dissipates and the ridge becomes more dominant ending the rain 
chances. High temperatures warm slightly under the ridge...except 
a brief dip across the far northeast on Sunday due to clouds and 
rain. Low temperatures will be near to slightly above seasonable 
levels.
