TK’s Special Briefing…. (745am CT-Fri/17Apr2015)

Austin / Travis County and South Central Texas Weather Update #6
Prepared by UT University/Incident Meteorologist Troy Kimmel
745am CT – Friday / 17 April 2015

Multi Day Severe Weather Risk…
… Severe Thunderstorm Risk Again Today into Tonight …
… Severe Thunderstorm Risk Again Saturday into Saturday Night …

… NWS/Austin-San Antonio Flash Flood Watch for Areas east of the the IH35
Corridor Counties 1pm Today Until 1am Tomorrow Morning … This DOES NOT
include the IH35 corridor counties at this time

At 730am… I do not see any precipitation on NWS Doppler weather radar anywhere
in the local area / IH35 corridor counties…

The latest short range high resolution computer models suggest a resurgence of rain
showers and thunderstorms.. some possibly severe.. by early to mid afternoon. This
occurs as we start to get daytime heating today and instability increases again in
combination with passing upper air disturbances. These thunderstorms may contain
larger hail in excess of 1″ in diameter and damaging straight line thunderstorm¬† winds
at or above 58 mph along with frequent deadly cloud-to-ground lightning. There is a
smaller risk of tornadoes mainly south of the Austin area proper. This thunderstorm
risk will continue into the nighttime hours tonight. Upwards of 1 to 2 inches of rain with
some isolated higher totals could occur.. mainly in areas along and east of the IH35
corridor counties.

Here is the NWS/Storm Prediction Center Day 1 severe weather outlook (7am today
to 7am Saturday)…


In closing, permit me to talk about the severe thunderstorm risk again tomorrow
into tomorrow night. The outlook area.. from the NWS/Storm Prediction Center..
for 7am Saturday through 7am Sunday is quite similar¬† to today’s outlook…


In summary, we’re in a midst of a multi day severe thunderstorm risk for
the IH35 corridor counties. All interests are responsible for remaining weather
aware through the next couple of days.. have a way of receiving the latest weather
information and be ready to act in case the NWS issues advisories/watches
and/or warnings for your local area.

Here is a link to the latest NWS/Austin-San Antonio short fused advisories
and warnings in chronological order with the latest issuances at top (check the

current

Always remember that frequent cloud to ground lightning is the BIGGEST and
most common hazard with any thunderstorms.. when they threaten, please stay
indoors and away from electrical appliances and plumbing devices.

I will continuing to monitor…
