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
Birmingham, AL (KBMX), launched 12:00Z, 11.8 hours before the alert went out and 215 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 NATIONAL WEATHER SERVICE MOBILE AL 358 PM CDT SAT MAY 30 2015 .SHORT TERM [TONIGHT THROUGH SUNDAY AFTERNOON]...THE CENTRAL GULF COAST REMAIN IN BETWEEN A BROAD TROUGH TO THE WEST AND AN UPPER RIDGE OVER THE WESTERN ATLANTIC. THE COVERAGE OF SHOWERS AND THUNDERSTORMS THIS AFTERNOON HAS BEEN THE GREATEST OVER FAR WESTERN ZONES CLOSER TO THE UPPER TROUGH AND BETTER DEEP LAYER MOISTURE. MEANWHILE...SEABREEZE ACTIVITY HAS IGNITED OVER THE FLORIDA PANHANDLE. SHOWERS AND THUNDERSTORMS WILL GRADUALLY DISSIPATE ACROSS MOST OF THE AREA TONIGHT. AS AN UPPER SHORTWAVE EJECTS NORTHEASTWARD OUT OF THE BASE OF THE UPPER TROUGH TONIGHT...A COLD FRONT WILL MOVE INTO CENTRAL MISSISSIPPI. DUE TO THE HIGHER MOISTURE CONTENT AND APPROACHING SHORTWAVE AND COLD FRONT...WILL LEAVE ISOLATED TO SCATTERED ACROSS FAR NORTHWEST ZONES OVERNIGHT. THE UPPER TROUGH WILL ADVANCE EASTWARD THROUGH THE DAY ON SUNDAY WITH THE COLD FRONT ALSO PROGRESSING EASTWARD. AHEAD OF THE FRONT...MOISTURE LEVELS WILL INCREASE AND ALLOW FOR BETTER DEVELOPMENT OF SHOWERS AND THUNDERSTORMS. THE HIGHEST COVERAGE WILL BE WEST OF INTERSTATE 65 WITH SCATTERED COVERAGE TO THE EAST.

WITH THE SURFACE BOUNDARY STALLED OVER NORTHERN FL...LOW LEVEL FLOW OVER THE SOUTHEASTERN CONUS IS GENERALLY WEAK AND VARIABLE. RESULTANT TEXT GUIDANCE IS TEMPS AND POPS A BIT ABOVE SEASONAL. BOTH ECMWF AND GFS TEXT PRODUCTS ARE WITH A DEGREE OF EACH OTHER...ALONG WITH THE GFS ENSEMBLE MEAN. WITH GUIDANCE IS PRETTY GOOD AGREEMENT...HAVEN'T DEVIATED. WEDNESDAY NIGHT INTO FRIDAY...THE GFS AND ECMWF DIVERGE WITH THE HANDLING OF THE CLOSED LOW. THE ECMWF HAS A LOOSELY ORGANIZED LOW MEANDERING SLOWLY EAST OVER THE FL PENINSULA TO OVER THE FL ATLANTIC COAST. THE GFS ON THE OTHER HAND...DEEPENS THE LOW AND MEANDERS IT NORTHEAST ALONG THE ATLANTIC COAST...TO OVER THE GA/SC LINE BY FRI EVENING. THE GFS ALSO IS ADVERTISING THIS LOW DEVELOPING A SURFACE LOW OFF THE YUCATAN COAST...THEN TAKING IT NORTHEAST BEFORE STALLING IT WITH THE UPPER LOW OVER THE GA/SC STATE LINE. IN BOTH SCENARIOS...THE FA COMES UNDER DRY NORTHERLY FLOW...WITH A DRY PERIOD FRIDAY INTO SATURDAY AND TEMPS DROPPING TO AROUND SEASONAL LEVELS. && .AVIATION...VFR CONDITIONS WILL PREVAIL THROUGH MUCH OF THE PERIOD OUTSIDE OF ISOLATED TO SCATTERED SHRA/TSRA.
