Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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.

SHORT TERM...CONCUR WITH THE ETA/AVN THAT THE UPPER TROUGH WILL LIFT
SLOWLY NWD TDA...YET STILL CONTRIBUTE TO SYNOPTIC SCALE LIFT OVER
THE CWFA. EXPECT THE WEAK BNDRY CURRENTLY OVER THE SRN CWFA TO
PROVIDE SFC FORCING OVER THE CWFA TDA. PROXIMITY SOUNDINGS INDICATE
EXTREMELY MOIST CONDITIONS OVR THE REGION. THE COMBINATION OF
SFC-UPPER FORCING/COPIOUS MSTR WILL LIKELY RESULT IN WIDESPREAD PCPN
OVER THE CWFA TDA. WL MAINTAIN THE FFA FOR THE CWFA THROUGH 0Z WED.
AFTER 0Z...SIGNIFICANT DRYING/UPPER RIDGING EXPECTED TO TAKE PLACE.
WATER VAPOR IMAGERY CURRENTLY REVEALS THE DRYING ASSOCIATED WITH
THIS RIDGING MOVG WWD ACROSS THE CNTRL GULF. WL FCST AT LEAST LIKELY
POPS OVER THE CWFA TDA...WITH SIGNIFICANTLY LOWER POPS TONIGHT/WED.

EXTENDED...DO NOT ANTICIPATE PCPN THU-SAT...AS THE RIDGE
BUILDS/DRYING DEVELOPS OVER THE REGION. THE MRF PROGS THE FOREGOING
UPPER TROUGH TO ROTATE AROUND THE UPPER RIDGE AND AFFECT THE CWFA
AGAIN BY SUN. WL MAINTAIN A SLIGHT CHANCE FOR CONVECTION SUN-MON.

MARINE...DECENT DYNAMICS IN THE FORM OF UPR DIFLUENCE WL SUSTAIN
WIDESPREAD CONVECTION FOR AT LEAST ONE MORE FCST PERIOD. SOME STORMS
MAY CONTAIN MIX DOWN SOME STRONG WINDS AND WL MENTION THIS IN THE
FCST.  HOWEVER...IT DOES APPEAR THAT THESE DYNAMICS WL BEGIN
BREAKING DOWN LATER TDA AND ESPECIALLY TNT.  THUS...THE COVERAGE OF
PCPN WL BE ON THE DECLINE.  STILL THINK THERE WL BE ENOUGH RESIDUAL
LOW LVL MOISTURE TO KEEP IN ISOLATED POPS ON WED AND THU.  IT DOES
APPEAR THAT MARGINAL SCA CONDITIONS WL CONTINUE FOR THE
NEARSHORE/OFFSHORE WATERS FOR AT LEAST TDA WITH SCEC CONDITIONS FOR
THE BAYS.  ONSHORE FLOW WL SLOWLY RELAX TO MORE TYPICAL JULY LVLS AS
THE MODERATE LLJ SLOWLY DECREASES OVER THE NEXT FEW DAYS.
