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
Tuscon, AZ (KDMA), launched 00:00Z, 1.5 hours before the alert went out and 84 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.

NWS Tucson, AZ wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 5, 2:26 PM MST, 4 hours 6 minutes earlier.
Area forecast discussion, Jul 5, 2:26 PM MST, 4 hours 6 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 226 PM MST SAT JUL 5 2014 .SYNOPSIS...A CHANCE OF THUNDERSTORMS OVER THE WEEKEND. A WEAK DISTURBANCE IS EXPECTED TO HELP ENHANCE THUNDERSTORMS MONDAY AND TUESDAY BEFORE SOME DRYING LEADS TO A DOWNWARD TREND THE SECOND HALF OF NEXT WEEK. && .DISCUSSION...SHOWERS AND THUNDERSTORMS CONTINUED TO DEVELOP MAINLY IN THE MOUNTAINS THIS AFTERNOON WITH THE AID OF DAYTIME HEATING AND A WEAK IMPULSE MOVING NORTH OUT OF SONORA MEXICO. THE AIR MASS REMAINED VERY MOIST AND THE STEERING FLOW WAS LIGHT AND VARIABLE SO THE MAIN CONCERN THROUGH THIS EVENING WILL BE LOCALLY HEAVY RAINFALL. CANNOT RULE OUT SOME STRONG WINDS WITH THE HEAVIER DOWNPOURS. THE ACTIVITY SHOULD PRETTY MUCH DIMINISH AFTER SUNDOWN AND AS THE IMPULSE MOVES OVER CENTRAL ARIZONA. SIMILAR COVERAGE EXPECTED TOMORROW...BUT THE MEDIUM RANGE MODELS CONTINUED TO ADVERTISE A STRONG IMPULSE ROTATING THROUGH SOUTHEAST ARIZONA ON MONDAY. THIS FEATURE COULD RESULT IN MORE ORGANIZED THUNDERSTORM ACTIVITY MONDAY AFTERNOON AND EVENING...WITH LINGERING AREAS OF RAIN MONDAY NIGHT. THAT SAID...WILL KEEP THE TREND OF INCREASING POP VALUES FOR MONDAY COMPARED TO TODAY AND SUNDAY. THEREAFTER...THE LARGE SCALE PATTERN BECOMES LESS FAVORABLE FOR A DECENT COVERAGE IN STORMS AS THE IMPULSE ROTATES OVER SOUTHERN ARIZONA AND TAKES A TURN TOWARD THE NORTH THROUGH SOUTHEAST CALIFORNIA. BY NEXT WEEKEND THOUGH...MODELS HINT AT THE FLOW PATTERN BECOMING MORE FAVORABLE FOR WIDESPREAD THUNDERSTORM ACTIVITY STARTING SATURDAY INTO THE FOLLOWING WEEK. && .AVIATION...VALID THROUGH 07/00Z. SCATTERED THUNDERSTORMS THRU 06/04Z WITH FOCUS OVER THE MOUNTAINS AND WESTERN PIMA COUNTY. DUE TO LIGHT WINDS ALOFT SLOW AND ERRATIC STORM MOTION EXCEPT WHERE DRIVEN BY STRONG OUTFLOWS. OTHERWISE FEW-SCT080 SCT-BKN120. WIDELY SCT THUNDERSTORMS REDEVELOPING AFT 06/19Z...AGAIN MAINLY OVER MOUNTAINS. WINDS VARIABLE TO 10 KTS EXCEPT VCNTY THUNDERSTORMS. AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS. CERNIGLIA && .FIRE WEATHER...SCATTERED THUNDERSTORMS INTO THIS EVENING. WITH SLOW MOVEMENT...THE STORMS ARE CAPABLE OF HEAVY RAINFALL. EXPECTING SOME WIDELY SCATTERED STORMS AGAIN SUNDAY...PRIMARILY OVER THE MOUNTAINS. MONDAY AND TUESDAY EXPECT AN INCREASE IN THE AMOUNT OF CONVECTION ACROSS THE AREA...THEN CHANCES DIMINISHING SOME WEDNESDAY ONWARD. HUMIDITY LEVELS WILL REMAIN HIGH THROUGH WEDNESDAY THEN DIMINISH A BIT THEREAFTER. WINDS THROUGH NEXT WEEK WILL BE GENERALLY LESS THAN 15 MPH WITH THE EXCEPTION OF STRONG GUSTY OUTFLOW WINDS UNDER AND AROUND ANY THUNDERSTORMS.
