Subject: 100 pm Thursday June 12 -- Severe Storms Today and Tonight

South Central Texas Partners...

...HEADLINE...Strong to severe thunderstorms from late this afternoon through late tonight.

...AREA OF CONCERN...The best chance for severe storms will be along and north of U.S. Highway 90, including the Austin and San Antonio metro areas.

...IMPACTS...The most likely threats are hail and damaging winds, but tornadoes and heavy rainfall resulting in localized flash flooding are also possible. Some storms may produce very large hail (greater than golf ball-size), and damaging winds may be as high as 75 mph. 

 ...TIMING...Supercell thunderstorms should develop over the Hill Country by 4-5 pm with some moving east-northeast and others almost due south. Later, a line of strong to severe thunderstorms is expected to sweep across areas along and east of I-35 between 9 pm and 2 am.

...CONFIDENCE...Moderate.

...DISCUSSION...A weak cold front will stall just to the north of our area this afternoon. This front and the higher terrain of the Hill Country will be the sources of lift for thunderstorms to develop by 4-5 pm. These storms will likely become supercells and bring all types of severe weather: tornadoes, large hail, damaging winds, heavy rain/ local flash flooding, and intense lightning. Later on in the evening, a squall line is expected to sweep from north to south across areas along and east of I-35. The main threats with the line of storms will be damaging winds and heavy rain/flash flooding. At this time we do not expect significant river flooding, but campgrounds, low water crossings, and other areas right on river and creek banks are at risk, and persons in those areas should closely monitor the weather through the night. There is also a Heat Advisory in effect for the Rio Grande Plains today and Friday.
