Austin / Travis County and South Central Texas Weather Statement #1
Prepared by UT University/Incident Meteorologist Troy Kimmel
345pm CT – Friday / 13 April 2018
As we go into our weekend, two weather related risks that we face here on the IH35 corridor… I will continue to monitor both of these risks…
As a strong upper level low pressure areas passes north of the area by tonight and an associated surface cold front moves across the IH35 corridor by midnight tonight, high resolution model guidance suggests that a few strong thunderstorms may develop just to our west or overhead between 6 and 8pm tonight and progress east southeast across the area.
Larger hail and damaging straight line thunderstorm winds are the biggest threat along with a lesser risk of tornadoes. The severe weather risk will be greatest in areas to the north, northeast and east of the Austin area proper. Dangerous cloud-to-ground lightning will accompany any thunderstorms that develop.
Any outdoor activities this evening into tonight should be weather aware and be ready to seek safe shelter if thunderstorms develop.
(2) .. A Wildfire Risk for Tomorrow into Tomorrow Night ..
.. A Fire Weather Watch Has Been Issued for the IH35 Corridor and Westward ..
Please pay close attention to the latest information tomorrow into tomorrow night from local officials reference this wildfire risk.
