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.

.SHORT TERM...
CONVECTION HAS BEEN SLOW TO DEVELOP THIS AFTN GIVEN DEEP/MIXED
DIVERGENT WESTERLY FLOW AND LACK OF MUCH FOCUS ATTM. HOWEVER EXPECT
AS WEAK S/W AXIS DRIFTS INTO THE W LATER...WILL SEE AT LEAST SCTD
TSRA DEVELOP OVER THE NEXT FEW HOURS WITH ONLY ISOLD ELSW PER STRONG
CAP OVERHEAD. MODELS SUGGEST THAT SOME OF THE WRN PRECIP WILL SLOWLY
WORK ACROSS THE BLUE RIDGE LATE THIS EVENING/OVRNGT BUT IFFY AS TO
ANY COVERAGE AFTER MIDNGT. THEREFORE WILL KEEP LOW CHCS GOING W
MAINLY THIS EVENING WITH SLIGHT CHCS OUT E AND ELSW UNTIL ABOUT
MIDNGT. OTRW SIMILAR TO THE PAST FEW NIGHTS WITH PC FOR DEBRIS
CLOUDS AND SOME PATCHY FOG/HAZE ARND. TEMPS GNRLY IN THE 60S. FRONT
TO THE W REMAINS THE MAIN CONVERGENCE AREA TUE IN RESPONSE TO LAST
STRONG S/W EJECTING NE TOWARD THE OH VALLEY LATE. SINCE CWA LOOKS TO
REMAIN SE OF THE MAIN UVV CORRIDOR...APPEARS AGAIN FORCING DUE TO
OLD BOUNDARIES AND OROGRAPHIC HEATING GIVEN HIGH THETA/PWAT IN
PLACE. LESS CAP ALSO SUPPORTS A LITTLE QUICKER/MORE WDSPRD COVERAGE
SO WILL LEAN CHCS E ACROSS THE BLUE RIDGE. OTRW WARM/STICKY WITH
TEMPS AGAIN 78-85 W AND ARND 90 SE.
&&
.LONG TERM...
FIRST CHALLENGE IS THE TIMING/POSITION OF THE FRONT MID-WEEK. MODEL
TRENDS HAVE BEEN SLOWER WITH THE SYSTEM. HAVE TRENDED TIMING A BIT
SLOWER WITH BEST CHANCES WEDNESDAY NIGHT WEST...AND THEN LINGER
PRECIP A LITTLE LONGER DURING THE DAY THURSDAY. FRONT RETURNS NORTH
FRIDAY AS A WARM FRONT AND RETURNS PRECIP CHANCES TO THE AREA.
HEADING INTO SATURDAY WE GET BACK INTO DIURNAL PRECIP CHANCES WITH
THE BEST CHANCE NORTH TOWARDS THE WARM FRONT. BY EARLY NEXT WEEK AN
UPPER TROUGH IS PROGGED TO DEVELOP IN THE CENTRAL U.S. AND ITS
ASSOCIATED COLD FRONT WILL BE GETTING CLOSER TO THE AREA.
GOOD...MOIST SOUTHWEST FLOW WITH INCREASING JET DYNAMICS IN ADVANCE
OF THIS SYSTEM SHOULD KEEP DAILY CHANCE OF CONVECTION WITH THE BEST
CHANCE WEST.
