by

Austin / Travis County and South Central Texas Weather Update #17
Prepared by UT University/Incident Meteorologist Troy Kimmel
225pm CT – Saturday / 18 April 2015

…. “Enhanced” Risk of Severe Thunderstorms for Texas Hill Country….
….”Slight” Risk of Severe Thunderstorms IH35 Corridor and Eastward ….

As anticipated, clouds have broken  with surface heating acting to quickly
destabilize the atmosphere over the central and western parts of our area.
This is happening as the next upper level low pressure disturbance.. rotating
in a counterclockwise direction around the upper low over Colorado.. heads
eastward out of west Texas. As this occurs.. atmospheric lift and instability
will cause the development of rain showers and strong thunderstorms to our
distant west over the next few hours with severe weather a possibility..

The NWS/Storm Prediction Center has issued a SEVERE THUNDERSTORM
WATCH valid until 9pm tonight for the Texas Hill Country west of the IH35
corridor counties. The IH35 corridor counties.. Williamson.. Travis and Hays
are NOT in this watch.
