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

Santa Teresa, NM (KEPZ), launched 12:00Z, 7.1 hours before the alert went out and 100 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, May 4, 3:56 AM MDT, 9 hours 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM
356 AM MDT MON MAY 4 2015

.SYNOPSIS...
AN UPPER LOW WILL MOVE TO ARIZONA THIS AFTERNOON AND ACROSS NORTHERN
NEW MEXICO ON TUESDAY. THIS WILL ALLOW ISOLATED SHOWERS AND
THUNDERSTORMS TO CONTINUE TODAY AND TONIGHT. THE LOW MOVING ACROSS
NEW MEXICO TUESDAY WILL ALLOW MOISTURE TO DIMINISH...WITH JUST A
SLIGHT CHANCE FOR THUNDERSTORMS OVER THE MOUNTAINS. TEMPERATURES
WILL RUN AT TO SLIGHTLY ABOVE NORMAL. WEDNESDAY INTO THE WEEKEND A
DRY SOUTHWEST FLOW ALOFT WILL DEVELOP AND KEEP THE AREA DRY.
AFTERNOONS WILL BECOME BREEZY...BUT DESPITE THIS...TEMPERATURES WILL
REMAIN NEAR NORMAL.

&&

.DISCUSSION...
UPPER LOW NOW JUST OFF THE SOUTHERN CALIFORNIA COAST. HAS NOT BEGUN
TO ENTRAIN MUCH MOISTURE SO HARD TO SEE. DRY SLOW CONTINUES OVER THE
AREA BUT SO DOES A 130 KT JET WITH WEAK DISTURBANCES. THIS SHOULD BE
GOOD ENOUGH FOR ANOTHER ROUND OF SHOWERS/THUNDERSTORMS TODAY AND
TONIGHT. WINDS LIKELY MAIN HAZARD AGAIN. LATEST HRRR SHOWS DCAPES OF
UP TO 850 J/KG. DEW POINT DEPRESSIONS SLIGHTLY LESS THAN SUNDAY BUT
STILL AROUND 50 DEGREES THIS AFTERNOON. WIND GUST POTENTIAL LOOKS TO
BE 40-50 MPH WITH ANY STORMS/SHOWERS. LACK OF DEEP MOISTURE AND/OR
HIGH DEW POINTS SHOULD PRECLUDE HEAVY RAINFALL...MAYBE .25 - .50
INCHES WITH THUNDERSTORMS.

UPPER LOW TO WESTERN NEW MEXICO TUESDAY MID DAY AND THEN OVER THE
COLORADO ROCKIES BY TUESDAY EVENING. THIS LOW PASSAGE AND WEAK
PACIFIC SURFACE FRONT WILL HELP TO SCOUR OUT MOISTURE SOME. MODELS
STILL SHOWING JUST ENOUGH RESIDUAL MOISTURE AND INSTABILITY TO KICK
OFF A FEW THUNDERSTORMS OVER THE MOUNTAIN ZONES. OTHERWISE POPS OUT
FOR THE REST OF THE FORECAST PERIOD...AS DRY SOUTHWEST FLOW ALOFT
AHEAD OF A WEST COAST UPPER TROUGH DEVELOPS AND PERSISTS INTO THE
WEEKEND. AFTERNOONS WILL BECOME BREEZY TO WINDY THURSDAY THROUGH
SATURDAY. DESPITE THIS PATTERN HIGH TEMPS SHOULD REMAIN AT OR
SLIGHTLY ABOVE NORMAL.

&&

.AVIATION...VALID 04/12Z-05/12Z...
VFR CONDITIONS SHOULD PERSIST AT ALL TAF SITES THRU THE PERIOD. WEAK
DISTURBANCES WILL RESULT IN ANOTHER ROUND OF HIGH BASED SHOWER
ACTIVITY DEVELOPING AFTER 20Z WITH 26015G25KT SCT-BKN080-100
PREVAILING. -TSRA SCT-BKN080CB POSSIBLE OVER HIGHER TERRAIN AND AT
KTCS DURING THE AFTERNOON AND EARLY EVENING.
&&

.FIRE WEATHER...
A FEW WEAK DISTURBANCES ALOFT WILL MOVE PAST THE REGION TODAY AND
TONIGHT AS AN UPPER LOW TRACKS EAST FROM THE COAST OF SOUTHERN
CALIFORNIA. THIS WILL BRING ANOTHER ROUND OF MAINLY HIGH BASED
SHOWER ACTIVITY TO THE FIRE ZONES. INITIALLY MOST OF THE SHOWERS
WILL EVAPORATE BEFORE REACHING THE SURFACE WHICH WILL PRODUCE
LOCALLY GUSTY WINDS. THE BEST CHANCE FOR ACTUAL WETTING PRECIP WILL
BE OVER THE HIGHER TERRAIN OF THE NORTH AS WELL AS THE FAR EASTERN
FIRE ZONES THIS AFTERNOON AND EVENING.

MIN RH VALUES WILL RUN ABOUT 2O PERCENT FOR THE LOWLANDS AND 30
PERCENT FOR THE MOUNTAINS TODAY. AS DEEP WESTERLY FLOW DEVELOPS
TUESDAY MIN RH VALUES WILL DROP ABOUT 5 PERCENT WITH AN ADDITIONAL 5
PERCENT DECLINE FOR THE REST OF THE WEEK AHEAD. AS ANOTHER STRONGER
UPPER STORM APPROACHES LATE WEEK STRONGER AFTERNOON SURFACE WINDS
WILL DEVELOP WHICH COULD LEAD TO SOME FIRE WEATHER CONCERNS FOR THE
THURSDAY THRU SATURDAY PERIOD.
