NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
556 PM CST Thursday Nov 20 2014 


Discussion...update for 00z aviation below. 


&& 


Aviation...MVFR ceilings currently prevail along and east of a 
czt-erv-gtu line...including aus/Sat terminals...and will expand 
west through the evening reaching drt around 04z. Patchy -ra and 
isolated rain showers will continue through the evening along and east of 
I-35...and impact the aus terminal through 02z. Ceilings will 
lower through the late evening and eventually reach IFR at 
aus/Sat/ssf around 05z-06z...along with a mix of MVFR visibilities 
in br. Confidence increasing that stratus will lower overnight... 
with LIFR ceilings and IFR visibilities developing at 
aus/Sat/ssf/drt between 08z-12z and persisting through 17z. 
Ceilings eventually become MVFR again at aus/Sat/ssf and VFR at 
drt around 18z Friday.

Previous discussion... /issued 330 PM CST Thursday Nov 20 2014/ 


Short term (tonight through Friday night)... 
low level moisture will slowly increase across south central Texas 
through Friday evening as a surface high pressure system sits over 
the Middle-Atlantic States. Slight chance to chance of showers and 
even isolated thunderstorms are expected across the eastern half 
of south central Texas Friday as instability increases. Friday's 
highs will reach the lower 70s across most areas with middle 70s over 
the southern part of the Rio Grande. Chances for rain will 
increase across the entire region Friday night as an upper level 
trough pushes across central Texas. 


Long term (saturday through thursday)... 
a potent upper level system is forecast to push across the area on 
Saturday. Ahead of the system...surface dewpoints are anticipated 
to be in the middle 60s with middle to upper level southwest winds 
supporting strong to severe storms. Severe storm parameters are 
even supporting isolated super cells capable of producing tornadoes. 
However...the main weather threats for this event will be large 
hail and damaging winds. Storms will push across The Hill 
Country/Edwards Plateau area Saturday morning into the afternoon period. 
There is a six hour window Saturday afternoon from noon to 6 PM 
for organized cells to form and track to the northeast. Areas 
along and east of Highway 281 should monitor weather 
conditions closely for latest information and updates as this 
event unfolds. 


Saturday night...the upper level storm system is forecast to push 
to the northeast and away from the area with weather conditions 
improving from west to east. By Sunday...a dry cold front will 
push across the area followed by a cooler airmass. This airmass 
will keep temperatures in the middle 60s for highs and middle 30s to 
lower 40s through at least Wednesday of next week.
