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.

AFTER SUNRISE. WILL CONTINUE LESSER POP ACROSS THE SOUTH...BUT WITH
A BETTER CHANCE OF THUNDER AS THE REMANTS OF THE VORT MAX OVER
GEORGIA MOVES EAST...BUT SKIRTING SOUTH OF THE AREA. THE WEDGE WILL
BE LOCKED FURTHER INTO PLACE DUE TO THE EVAPORATIVE COOLING AND LOW
LEVEL MOISTURE IN THE STABLE LAYER SHOULD PRODUCE AT LEAST MOSTLY
CLOUDY SKIES TOMORROW WITH HIGHS GENERALLY 65 TO 70.

ISENTROPIC LIFT KICKS IN TOMORROW NIGHT WITH A CHANCE OF RAIN
DEVELOPING AS EARLY AS SUNRISE IN THE WEST. SHOULD SEE RAIN SPREAD
OVER THE REMAINDER OF THE CWFA DURING THE DAY. BOTH GFS AND ETA
DEPICT A VORT MAX LIFTING NORTHEAST OUT OF THE GULF STATES MONDAY
NIGHT WHICH SHOULD CONTINUE THE SHOWERS AND INTRODUCE A BETTER
CHANCE OF TSRA AS THE WARM FRONT LIFTS NORTH.
