Austin / Travis County and South Central Texas Weather Update #9
Prepared by UT University/Incident Meteorologist Troy Kimmel
445pm CT – Friday / 17 April 2015

Severe Thunderstorm Watch for IH35 Corridor Counties Continues Until 7pm …

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

At 445pm… no severe weather is indicated. Rain showers and thunderstorms are
spreading northward into the Austin metro area and the IH35 corridor counties.
Dangerous and deadly cloud-to-ground lightning is accompanying these
thunderstorms along with periods of heavier rain as well as gusty wind. This will
make what would, under a clear sky, be an otherwise usual Friday afternoon rush
hour traffic headache into something twenty times as bad. Use caution if you must
be on the roadways.

The latest short range high resolution computer models suggest a fairly progressive
movement of these cells through the area over the next few hours. As a result, rainfall
should remain on the beneficial side.. especially where it falls over the Texas hill country
which is still in drought. Although we need to watch this closely, I’m thinking that we’ll
see some one and two inch rainfall totals across the area with heaviest rainfalls in areas
to our south and southeast in the current flash flood watch area.

I’ll continue to monitor.. tk
