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

WEST CENTRAL TEXAS FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN ANGELO TX
330 PM CDT SUN JUN 16 2003

.CURRENT...COLD FRONT IS NEAR I-10 WITH SHOWERS AND THUNDERSTORMS
ALL ALONG THE SOUTHERN TIER OF COUNTIES.

.TODAY...WILL GO WITH THE HIGHEST POPS ACROSS THE SOUTHERN COUNTIES
TODAY WITH FRONT. OTHERWISE TO THE NORTH...STILL UNDER SOME
INFLUENCE OF 50H LOW OVER NORTHEASTERN TEXAS. THIS COULD HELP TO
PRODUCE SOME ISOLATED ACTIVITY THIS AFTERNOON. TEMPERATURES JUST
ABOUT THE SAM AS YESTERDAY.

.TONIGHT-MONDAY...50H LOW CONTINUES TO PUSH TO THE EAST AND EFFECTS
ON THE AREA TO LESSEN THROUGH THE REMAINDER OF THE PERIOD. WILL
CONTINUE TO TREND POPS DOWN TO 10 PERCENT OR BELOW AND GRADUALLY
TAKE MENTION OUT OF THE FORECAST.

.TUESDAY-SATURDAY...RIDGE WILL BUILD INTO THE AREA...MAINLY TO THE
WEST AND KEEP THE AREA IN NORTH TO NORTHWEST FLOW THROUGH THE
PERIOD. ALTHOUGH THIS WOULD NORMALLY BE FAVORABLE REGIME FOR
PRECIPITATION...THERE IS NOTHING THAT I CAN HANG MY HAT ON AT THIS
TIME TO MENTION IN THE FORECAST. WILL PUT VERY LOW POPS IN THE GRIDS
AND WAIT FOR LATER MODEL RUNS TO SEE IF SOMETHING CAN ADDED TO THE
FORECAST. IT IS ABOUT THAT TIME OF YEAR FOR THE RAINS TO STOP AND
GET HOT. ALSO TRENDED TEMPERATURES UP A FEW DEGREES IN THE LATTER
PORTION OF THE EXTENDED AS SHOULD HAVE ENOUGH TIME BY THEN TO DRY
OUT THE GROUND TO GET SOME HEATING GOING. ALTHOUGH IT LOOKS TO BE
GETTING WARMER...STILL NOT AS WARM AS IT COULD BE THIS TIME OF YEAR.
