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 00:00Z, 10.0 hours before the alert went out and 136 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 27, 3:53 AM CDT, 1 hour 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
353 AM CDT MON APR 27 2015

.SHORT TERM /NOW THROUGH TUESDAY/...CURRENTLY THE UPPER LEVEL LOW
IS CENTERED OVER NEW MEXICO WITH A BROAD AREA OF DIFFLUENCE ALOFT
FROM NORTH TO SOUTH CENTRAL TEXAS. A COLD FRONT IS MOVING SOUTHEAST
ACROSS THE AREA WITH A LINE OF THUNDERSTORMS DEVELOPING WITH FROPA.
THE LATEST RADAR SCANS SHOW THE LINE WEAKENING FURTHER SOUTH OF CRP
BUT DEWPOINTS STILL RANGE BETWEEN 75 TO 79 DEGREES ALONG THE NORTHERN
COUNTIES WITH SE WINDS IN PLACE. SOME OF THE STORMS DEVELOPING OVER
CRP AREA COULD MAKE ITS WAY INTO THE NORTHERN COUNTIES OF BROOKS AND
KENEDY. AS A RESULT INCREASE POPS FOR THE POTENTIAL OF SOME
CONVECTION OCCURRING IN THE EARLY MORNING HOURS. AS THIS LOW
MOVES FURTHER EAST TODAY...EXPECT FROPA TO ARRIVE BY MID DAY WITH
ABUNDANCE OF DRY AIR STARTING TO FILTER IN FROM THE WEST. ONCE THE
DRY AIR BEGINS TO MOVE INTO THE AREA...THE RAIN CHANCES WILL BE
LIMITED FOR ANY CONVECTION THIS AFTERNOON. HOWEVER...STRONGER
PRESSURE GRADIENT BEHIND IT WILL INCREASE NORTHWEST WINDS BETWEEN
15 TO 20 MPH WITH GUSTS UP TO 25 MPH. THE LATEST AQI KEEPS US
UNDER A MODERATE AIR QUALITY AT THIS TIME FOR TODAY BUT AS THE
FRONT MAKE ITS WAY INTO THE AREA WILL ALLOW FOR THE HAZE AND MIST
TO MOVE FURTHER SOUTH INTO THE GULF OF MEXICO AND GIVE THE CWA A
BREAK OF THE AGRICULTURAL BURNING SMOKE. THIS DRY AIRMASS WILL
CLEAR SKY CONDITION ALLOWING FOR MORE DAYTIME MIXING TODAY. HIGH
TEMPERATURES WILL BE HOT RANGING FROM 90 TO 93 DEGREES ALONG THE
RIO GRANDE VALLEY.

TONIGHT...THE CLOSED LOW MOVES SLOWLY EAST INTO NORTHERN TEXAS AND
OKLAHOMA WITH A RELAX PRESSURE GRADIENT EXPECTED OVERNIGHT. THE LIGHT
WINDS AND CLEAR SKY WITH A FEW CIRRUS STREAMING ACROSS WILL ALLOW FOR
TEMPERATURES TO LOWER TO MID TO LOW 60S. OVERNIGHT THE SURGE OF HIGH
PRESSURE WILL MAKE  IT THROUGH THE AREA INCREASING NORTHERLY WINDS
TUESDAY. THE BREEZE CONDITIONS WILL PREVAIL THROUGH THE DAY WITH GUSTY
WINDS. THICKNESS VALUES CONTINUE TO SHOW A LOWERING TREND WITH THIS LOW
WHICH WILL ALLOW FOR TEMPS TO REMAIN IN THE MID TO UPPER 70S AND NEAR
80S ALONG THE RGV. THIS WILL POSSIBLY BE THE LAST TIME WE WILL SEE TEMPS
THIS LOW UNTIL FALL. DUE TO THE ABUNDANCE OF DRY AIR IN THE AREA THE
POTENTIAL FOR RAIN IS NIL.
&&

.MARINE...
NOW THROUGH TUESDAY...UPPER LEVEL LOW OVER NEW MEXICO WILL TRAVEL EAST
DURING THE SHORT TERM. THIS CLOSED LOW WILL BRING A COLD FRONT TODAY SHIFTING
WINDS TOWARDS THE NORTH TO NORTHWEST THIS AFTERNOON. THE SEAS WILL NOT INCREASE
AS MUCH TODAY AS THE GRADIENT REMAINS RELAX. CONDITIONS BEGIN TO CHANGE TUESDAY
AS THE MAIN SURGE OF THE HIGH PRESSURE MAKE ITS WAY SOUTHEAST INCREASING WINDS
AND SEAS TUESDAY DURING THE DAY. SCA WILL BE POSSIBLE TUESDAY DUE TO STRONG WINDS
AND HIGH BUILDING SEAS.
