Austin / Travis County and South Central Texas Weather Update #3
Prepared by UT University/Incident Meteorologist Troy Kimmel
1015am CT – Wednesday / 28 March 2018
.. Another Round of Rain Showers and Thunderstorms over the Next Couple of Hours ..
.. NWS Austin-San Antonio Issued Flash Flood Watch Continues Until 7pm …
At mid morning.. another developing complex of rain showers and thunderstorms..
to our south southwest.. is sweeping east northeastward as it expands northward a bit.
These thunderstorms have produced / are producing some quarter size (1.00″) or
larger in the area from San Antonio westward. I think that most of the strongest
thunderstorm activity will remain south of the Austin metro area but I do expect
frequent lightning in the Austin metro area and the IH35 corridor with scattered to
numerous thunderstorms through midday. Some hail may occur in areas mainly south
of Austin. Additional rainfall in the Austin metro area/IH35 corridor will average
somewhere in the 1/4 to 1/2 inch range with heavier rain possible to the south of the area.
Overnight rainfall was, on average, mostly in the 1 to 3 inch range, but pockets of 4 to
5 inch amounts occurred, based on the LCRA Hydromet gauge network, in eastern parts
of Travis County as well as central and eastern parts of Hays County.
By late tonight into Thursday, the upper level low pressure area as well as the last in a
series of weak fronts will move through the area with clouds and rain chances decreasing
and, indeed, sunshine, westerly winds and warmer temperatures returning for most of the
A secondary cold front will pass through the area tomorrow night with cooler temperatures,
under a mostly clear sky, tomorrow night into Friday.
