Troy’s Special Briefing…. (145pm CT Sat/29Apr2017)

Austin / Travis County and South Central Texas Weather Update #2
Prepared by UT University/Incident Meteorologist Troy Kimmel
145pm CT – Saturday / 29 April 2017

.. Enhanced Severe Thunderstorm Risk Continues This Afternoon into Tonight
with Cold Frontal Passage ..

At 200pm.. the warmer, more stable air aloft – referred to as a “temperature
inversion” – continues to hold strong across the area as the cold front/dry line continues
to progress east southeastward along a line from Durant, OK southwestward to
about 40 miles west of the DFW metroplex to just west of Hamilton, TX to northeast
northeast of Junction where it intersects with a surface dry line that extends southward
to west of Del Rio. At this time, because of the more stable air aloft, we’re seeing little
in the way of precipitation along and ahead of the front.

Temperatures, ahead of the front over central and north Texas, are approaching
90 degrees along the IH35 corridor from San Antonio through Austin northward to the
DFW metrplex while immediately behind the front the temperatures fall into the
50s and 60s. Temperatures over the Texas panhandle are in the 30s and 40s.

The real question is… when are the thunderstorms to develop along the front? There’s
little question in my mind that they will, but they’re already a bit behind my schedule I
set in the last update. I feel that when they do, which will come with weakening and
removal of the inversion, there will be quite a bit of energy released and the development
should be fairly rapid.

Let’s continue to be “weather aware” and to listen to the latest updates from the
National Weather Service…. I’ll keep you advised.
