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

Brownsville Intl, TX (KBRO), launched 00:00Z, 1.5 hours before the alert went out and 163 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.

Area forecast discussion, Jun 3, 7:40 PM CDT, 48 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
740 PM CDT WED JUN 3 2009

.DISCUSSION...TORNADIC THUNDERSTORMS HAVE DEVELOPED OVER
BROOKS...HIDALGO AND STARR COUNTIES THIS EVENING. THESE TORNADIC
THUNDERSTORMS ARE MOVING SOUTH TOWARD MCCOOK AND BUILDING WEST TO LA
GLORIA. THESE THUNDERSTORMS HAVE LEFT COPIOUS AMOUNTS OF RAIN IN
FALFURRIAS...WHERE STREET FLOODING IS PREVALENT. THE ATMOSPHERE
REMAINS VERY UNSTABLE AND OUTFLOW BOUNDARIES FROM THE NORTH ARE THE
LIFTING MECHANISM. EXPECT STRONG TO SEVERE THUNDERSTORMS TO CONTINUE
TO MOVE SOUTH INTO CENTRAL AND WESTERN HIDALGO COUNTY.
&&

.PREV DISCUSSION.../ISSUED 144 PM CDT WED JUN 3 2009/500MB RIDGE
ACROSS NORTHERN MEXICO EXPECTED TO BUILD EASTWARD INTO THE STATE THE
NEXT COUPLE OF DAYS. THIS WILL PROVIDE AN INCREASE IN SUBSIDENCE
ACROSS DEEP SOUTH TEXAS WITH LESS IN THE WAY OF CLOUDS AND RAIN
CHANCES THROUGH THE REST OF THE WEEK. TEMPERATURES WILL BE SLIGHTLY
WARMER AS A RESULT. WILL GO AHEAD AND BLEND MET/MAV MOS TEMPERATURES
THE NEXT COUPLE OF DAYS. WITH THE RIDGE ACROSS SOUTH TX THROUGH THE
WEEKEND INTO EARLY NEXT WEEK...VERY WARM AND HUMID CONDITIONS TO
PERSIST WITH NOT MUCH IN THE WAY OF RAIN CHANCES. WITH THE LACK OF
LOW TO MID LEVEL MOISTURE ACROSS THE WESTERN GULF OF MEXICO EARLY
NEXT WEEK...WILL KEEP MENTION OF RAIN CHANCES OUT OF THE FORECAST
GRIDS THROUGH THE REST OF THE PERIOD BUT WOULD NOT BE SURPRISED TO
SEE AN ISOLATED SHOWER OR TWO DURING THE AFTERNOON HOURS MAINLY
ALONG THE SEABREEZE.
&&

.AVIATION...THE INTERACTION BETWEEN AN OLD MCS BOUNDARY MOVING SOUTH
AND THE SEA BREEZE SPARKED SOME EARLY AFTERNOON SHOWERS WITH
EMBEDDED LIGHTNING IN THE VICINITY. THIS ACTIVITY MAY REACH MFE
WITHIN AN HOUR...WITH THE POSSIBILITY OF SEVERE WEATHER PASSING OVER
THE MFE AIRPORT AT 930 TO 10 PM.
&&

.MARINE...LOADED THE LATEST WNAWAVE4 GRIDS...WHICH KEEP SEAS LOW
THROUGH EARLY NEXT WEEK BEFORE FINALLY BUILDING THEM UP TO MODERATE.
OTHERWISE...LIGHT WINDS AND LOW SEAS WILL CONTINUE BECAUSE OF A WEAK
PRESSURE GRADIENT SPREAD OVER THE LOWER TEXAS COAST. THREE FEET SEAS
AT BUOY020 EARLY THIS AFTERNOON ARE COMPOSED MOSTLY OF EAST SWELL.
BEACH REPORTS SHOW SLIGHTLY LOWER SEAS CLOSER IN AND A LOW RISK OF
RIP CURRENTS. MARINE SHOWER ACTIVITY SHOULD TAPER OFF OVER THE NEXT
TWO OR THREE DAYS AS UPSTREAM H5 RIDGING MOVES OVERHEAD.
