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.

Area forecast discussion, Jun 27, 3:30 AM CDT, 10 hours 39 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 330 AM CDT SUN JUN 27 2004 .DISCUSSION... WILL BE DRASTICALLY CUTTING POP NUMBERS FOR TODAY. DRY AIR AS ADVERTISED BY YESTERDAYS MODEL SOLUTIONS WAS RIGHT ON TARGET. THIS MORNING...THE DRY SUBSIDENT AIR IS ON THE LEADING EDGE OF SHORT WAVE RIDGE BUCKELING UP INTO THE CENTRAL GULF COAST. THIS CAN BE SEEN BEST ON WV IMAGERY. THIS SUBSIDENT REGION SHOULD NOT MOVE MUCH TODAY WITH THE TROUGH KEEPING THINGS TIED UP TO THE WEST. THE GRADIENT WHERE SH/TS FORM WILL BE SHARP. CURRENTLY WILL GO WITH ISOLATED OVER THE EASTERN MOST PORTION OF AREA WHILE BETTER MOISTURE PROFILES HOLD ON FROM NEW ORLEANS WEST KEEPING POP NUMBERS A LITTLE HIGHER. INTERESTING THING TO SEE TODAY IS HOW THE SQUEEZE PLAY WILL BE HANDLED BY THE TWO SYSTEMS. ATTM A SHORT WAVE MOVING NE ALONG THE EAST SIDE OF THE TROUGH AXIS IN TX AND THE RIDGING OVER THE CENTRAL GULF COAST IS SQUEEZING AN AREA OF INCREASED MOISTURE BETWEEN THEM. CANT RULE OUT MORNING ACTIVITY STARTING UP DUE TO THIS FEATURE WHICH AFTER LOOKING AT RADAR IS ACTUALLY STARTING. THIS ACTIVITY SHOULD RELAX ONCE THE CURRENT SHORT WAVE OVER WESTERN LA EJECTS NE. THE NEXT ONE WILL BE MOVING IN LATER THIS MORNING AND AFTERNOON. WITH THE SHORT WAVE RIDGING IN BASICALLY THE SAME PLACE...WOULDNT BE SURPRISED TO SEE A FEW TS GO SEVERE SINCE WE SHOULD GET PLENTY OF HEATING THROUGH MID DAY AND THE SQUEEZE PLAY ONCE AGAIN COMMENCES DUE TO THE NEXT SHORT WAVE. THE LINE WHERE TS FORM AND/OR GO SEVERE SHOULD SET UP QUITE SHARP ONCE AGAIN. THE LINE SHOULD BE FROM POPLARVILLE TO NEW ORLEANS TO HOUMA. ANY CITY ALONG AND WEST OF THIS LINE WILL HAVE A CHANCE AT SEEING SCATTERED SH/TS AS WELL AS THE POSSIBILITY OF AN ISOLATED SEVERE TS. WILL MENTION THIS IN HWO THIS MORNING. TROUGH OUT WEST THAT HAS BEEN SENDING NUMEROUS SHORT WAVES ACROSS THE AREA SHOULD BEGIN TO LIFT OUT TODAY AND WEAKEN. THE STATIONARY SFC BOUNDARY OVER NORTHERN LA SHOULD NOT MAKE MUCH HEADWAY THROUGH THE WEEK AND AS THOUGHT YESTERDAY...THE AVN IS BACKING OFF ON DRY AIR SURGE FARTHER SOUTH AND IS NOW BRINGING IT EASTWARD WHICH SEEMS MORE LIKELY. THIS KEEPS THE MAJOR RAINFALL NORTH OF THE AREA. BUT POPS DO NOT DROP SIGNIFICANTLY BUT SETTLE BACK TO A MORE SEANONAL TREND FOR A WHILE. THE CBRZ BEGINS TO GET STARTED AGAIN BY MONDAY AND TUESDAY CAUSING EARLY SH/TS TO BREAK OUT AND MAKING ITS WAY AS FAR INLAND AS THE STATIONARY SFC BOUNDARY. OTHERWISE THE HOT MUGGIES ARE BACK FOR EXTREME SE LA AND SOUTH MISS COASTS. && PRELIMINARY POINT NUMBERS...
