The radar

The Austin/San Antonio radar (KEWX), 21 km from the middle of the area, began a volume at 23:13 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Corpus Christi, TX (KCRP), launched 12:00Z, 11.2 hours before the alert went out and 247 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Austin/San Antonio, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 21, 2:45 PM CDT, 3 hours 28 minutes earlier.

Area forecast discussion, Jun 21, 2:45 PM CDT, 3 hours 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
245 PM CDT SUN JUN 21 2015

.SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)...
NEARLY IDENTICAL SET UP TODAY AS YESTERDAY WITH CONVECTION FORMING
ALONG AND EAST OF THE 700 MB TROUGH AXIS AND PROPAGATING NORTHWARD
IN THE MEAN FLOW. THEREFORE...THE FORECAST HAS HIGH POPS AND
MENTION OF LOCALLY HEAVY RAIN IN THE WESTERN HALF OF THE AREA...
WITH CHANCE POPS FURTHER EAST. CONVECTION ALLOWING MODELS (CAMS)
INDICATE THE SPIN UP OF AN MCV...AND/OR THE TRANSITION OF THE 500
MB CLOSE LOW OVER NORTHEAST TEXAS SOUTHWESTWARD THIS EVENING. IF
THIS EVOLUTION OCCURS...RAINFALL ALONG THE RIO GRANDE PLAINS AND
IN THE WINTER GARDEN SOUTHWEST OF SAN ANTONIO WILL CONTINUE
THROUGH THE NIGHT. WHILE OVERALL QPF IS NOT EXPECTED TO BE
DRAMATIC...MANY LOCATIONS SOUTHWEST OF SAN ANTONIO MAY RECEIVE 1/2
TO 1 INCH AND A FEW SPOTS UP TO 2 INCHES BY 7 AM MONDAY.

LOOK FOR THE START OF THE DRYING...THEN WARMING TREND ON MONDAY AS
THE SUBTROPICAL RIDGE BEGINS TO RE-ESTABLISH ITSELF ACROSS THE
SOUTHERN U.S. AND DISSIPATES/MOVES THE PERSISTENT TROUGH OVER
TEXAS. PW IS STILL HIGH ENOUGH THAT LOW POPS WERE RETAINED ON
MONDAY.

&&

.LONG TERM (TUESDAY THROUGH SUNDAY)...
THE SUBTROPICAL RIDGE CONTINUES TO BUILD...BUT FLATTENS OUT...
THUS SUBSIDENCE WILL DRY THINGS OUT...AND TEMPS WARM...BUT NOT
PARTICULARLY HOT DUE TO THE LOW HEIGHTS OF THE RIDGE AND STILL
MOIST CONDITIONS USING UP NEAR-SURFACE HEATING FOR EVAPORATION.
TEMPS SHOULD CLIMB BACK TO SEASONAL NORMALS BY THE END OF THE
WEEK.

A LARGE LONGWAVE TROUGH IN THE GULF OF ALASKA WILL FORCE A RIDGE
OVER THE GREAT BASIN...AND THUS A RESULTING TROUGH OVER THE
MISSISSIPPI RIVER VALLEY. THIS WILL BRING A COLD FRONT INTO AT
LEAST OKLAHOMA...IF NOT NORTHEAST TEXAS AND POSSIBLY AS FAR SOUTH
AS OUR AREA EARLY NEXT WEEK. THE UPPER LEVEL FLOW WILL BE
FAVORABLE FOR MCS DEVELOPMENT OVER THE TEXAS PANHANDLE AND
OKLAHOMA...THEN PROPAGATING SOUTH INTO OUR AREA AND BRINGING A
CHANCE OF RAIN AND POSSIBLY SEVERE STORMS WITH DAMAGING WINDS. THE
FIRST CHANCE OF ANY OF THIS ACTIVITY OR RAIN IS NEXT SUNDAY.
