Did it verify

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

.MARINE...
NO CHANGES TO CWF HEADLINES...WILL RAISE GALES ALL ZONES W/ 7AM
PACKAGE (AS WE'LL EASILY BE WITHIN 12 HRS OF THE ONSET). THINKING
REMAINS SIMILAR TO PREV FCST...STRONG 1035 MB SFC HIGH OFF NEW
ENGLAND AND A 990 MB SFC LOW TRACKING INTO THE WESTERN GREAT LAKES
WILL MAKE FOR A VERY WINDY SITUATION ACRS THE WATERS. ONLY LIMITING
FACTOR IS MIXING THE WINDS DOWN OVER THE COLD WATERS (SFC WATER
TEMPS UPR 40S TO MID 50S). GRADIENT SHOULD BE SUFFICIENT FOR AT
LEAST 25-30 KT SUSTAINED AND GUSTS AROUND 35 KT (WILL CONTINUE TO GO
A LITTLE HIGHER OVER NRN CSTL WATERS WHERE GRADIENT IS A LITTLE
STRONGER). IN ADDITION TO THIS...ANY CONVECTION THAT GETS GOING
WOULD POTENTIALLY BRING STORM FORCE WIND GUSTS LATE AFTN/EVENG...AND
WILL HANDLE W/ SMW'S AS NEEDED.

ADDED A HIGH SURF ADVSY FOR ERN SHORE ZONES...FLOW REMAINS NEARLY
PERPENDICULAR TO THE SHORE THROUGH MUCH OF THE EVENT (AND STILL AT
ABOUT A 45 DEGREE ANGLE LATER THIS AFTERNOON/EVENING) SO NEARSHORE
WAVES SHOULD REACH 8 FT OR POSSIBLY A BIT HIGHER AT THAT TIME.
FARTHER SOUTH/ VA BCH TO THE NRN NC OUTER BANKS...ORIENTATION OF THE
COASTLINE IS SUCH THAT WINDS BECMG MORE SSE TO S (AS EXPECTED THIS
AFTN/EVENG) WOULD LIKELY KEEP SEAS CAPPED JUST BELOW 8 FT AT THE
SHORELINE (8-10 FT FARTHER OFFSHORE). THIS WILL BEAR WATCHING
HOWEVER AS IT WILL BE CLOSE.

CONDITIONS QUIET DOWN BY SUNDAY MRNG...SCA'S WILL NEED TO REPLACE
GALE WRNG'S AND WILL LIKELY LINGER INTO LATE SUN MRNG (FOR SEAS ON
THE COAST). OTHERWISE...GNLY SUB-SCA WINDS/SEAS EXPECTED WITH FLOW
BECMG SW FRO LATER SUN-MIDWEEK.

.TIDES/COASTAL FLOODING...
RAISED A CSTL FLOOD WRNG FOR OCEAN CITY FOR THIS EVENG'S HIGH TIDE
CYCLE...BASED ON PATTERN (DESPITE GFS BASED MDL GDNC ONLY PREDICTING
AT MOST MARGINAL MINOR FLOODING).
