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, 9.2 hours before the alert went out and 36 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, Apr 13, 3:52 AM CDT, 19 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
352 AM CDT MON APR 13 2015

.SHORT TERM /NOW THROUGH TUESDAY/...MCS/SQUALL LINE MOVED ACROSS
DEEP SOUTH TEXAS OVERNIGHT LAST NIGHT WITH SCATTERED SHOWERS AND
THUNDERSTORMS DEVELOPING ONCE AGAIN ACROSS THE MIDDLE AND LOWER
VALLEY AND MOVING NORTHEASTWARD. UPPER LEVEL LOW RESPONSIBLE FOR
HELPING ALONG THE MCS IS MOVING ACROSS SOUTHERN NEW MEXICO AND WILL
SLOWLY TURN NORTHEASTWARD TOWARD THE TEXAS PANHANDLE AND
WEAKEN/OPPEN UP AS IT BEGINS TO BECOME ABSORBED IN THE FLOW BY LATE
TUESDAY. SURFACE ANALYSIS DEPICTS A MESO HIGH BEHIND THE DEPARTING
MCS WITH A COLD FRONT WELL TO OUR NORTH AND A TROUGH LINE ACROSS THE
LEE OF THE SIERRA MADRES.

ATMOSPHERE IS WORKED OVER AND WILL TAKE MOST OF THE DAY TO RECOVER.
ONCE THIS FINAL ROUND OF CONVECTION MOVES EASTWARD THAT SHOULD BE
ABOUT IT FOR THE MORNING HOURS. HAVE DECREASED POPS ACROSS THE AREA
THIS MORNING BASED ON CURRENT TRENDS AND HRRR/RAP NOT DEVELOPING ANY
PRECIPITATION. TAKING A LOOK AT SOUNDINGS OUT WEST...IT WILL TAKE
TILL APPROXIMATELY MID AFTERNOON BEFORE ATMOSPHERE IS PRIMED UP ONCE
AGAIN. HOWEVER...THERE IS ADDED DRY AIR ON SOUTHWESTERLIES IN THE
MID AND UPPER LEVELS AND A LACK OF GOOD SFC CONVERGENCE. THEREFORE
WILL HAVE TO LOOK WEST TOWARDS THE HIGHER TERRAIN FOR ANY CONVECTION
INITIATION. DID ADD A LITTLE HIGHER POP IN THE UPPER VALLEY AND
AROUND THE RIO GRANDE RIVER FOR ANY CONVECTION THAT MAKES IT INTO
OUR CWA. SPC ALSO DISCUSSES THIS AND HAVE OUR AREA IN MARGINAL RISK
FOR SEVERE WEATHER THIS AFTERNOON AND TONIGHT AND THE UPPER VALLEY
AND NORTHERN RANCHLANDS IN A SLIGHT RISK FOR SEVERE WEATHER. MAIN
THREATS IS LARGE HAIL AND DAMAGING WINDS.

BECAUSE OF THE UNCERTAINITY OF INITIATION AND OVERALL ISOLATED
COVERAGE OF PRECIPITATION HAVE ELECTED TO LET THE FLASH FLOOD WATCH
EXPIRE.

FRONT SAGS INTO THE AREA TUESDAY AND WITH HIGH PWATS AND A DECENT
SURFACE FOCUS EXPECT SHOWERS AND THUNDERSTORMS TO DEVELOP IN THE MID
TO LATE MORNING HOURS AND LAST THROUGH MUCH OF THE DAY.

NOW THROUGH TUESDAY...MODERATE SOUTHEASTERLY WINDS AND MODERATE
SEAS ARE FORECAST TO BE PREVAILING THROUGH TUESDAY. ISOLATED
THUNDERSTORMS WILL BE POSSIBLE ESPECIALLY THIS MORNING AND ONCE
AGAIN TUESDAY. CLOUD TO SURFACE LIGHTNING STRIKES...GUSTY
