Austin / Travis County and South Central Texas Weather Update #14
Prepared by UT University/Incident Meteorologist Troy Kimmel
935pm CT – Friday / 17 April 2015
At 930pm.. via NWS Doppler weather radar.. I am watching as precipitation
moves off to the northeast of the Austin metro area and ends southwest to
northeast across the IH35 corridor counties.
Up to 9pm..
… there have been no reports of severe weather in the IH35 corridor
counties today
… the rainfall totals, since 12 noon, along the IH35 corridor counties
includes 0.40″ at Austin Bergstrom International Airport and 0.41″ at Austin
City (Camp Mabry). The LCRA Hydromet (http://hydromet.lcra.org/full.aspx),
as of the current time, shows heaviest totals to 1.21″ in their gauge near
Jonestown in northwest Travis County and 1.02″ at the Bull Creek gauge at Loop
360 in northwest Austin.. all other totals are less than 1 inch along the IH35
corridor. NWS Doppler weather radar storm total rainfall estimates show that
in excess of 2 inches of rain occurred tonight in a narrow strip between Lago
Vista.. Leander and Georgetown in extreme northwestern Travis and Williamson
counties.
As of 9pm.. the City of Austin website, www.atxfloods.com , shows only shows
eleven (11) of the 761 lower water crossings flooded at the current time.. with
three of those in the Cedar Park area (within that heavy rain area of western
Williamson and extreme northwestern Travis county).. the rest in northeastern
Caldwell and central and southwestern Bastrop counties.
The latest short range high resolution computer models suggests that we’re once
again in a break that should last until a few hours before sunrise when the
redevelopment of rain showers and thunderstorms is expected as another upper
air low pressure disturbance begins it’s move across the area.
Remember.. there continues, according to the NWS/Storm Prediction Center, to be
a risk of severe thunderstorms for tomorrow (Saturday) into tomorrow night as this
new disturbance moves through. Large hail, up to an inch in diameter or larger,
along with straight line thunderstorm winds gusts to 58 mph or higher is possible.
Frequent deadly cloud-to-ground lightning will be likely for tomorrow into tomorrow
night as the last disturbance moves across the area.
That’s it for now… will continue to monitor… tk
