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
NATIONAL WEATHER SERVICE ABERDEEN SD
815 PM CDT THU JUN 5 2003

.SHORT TERM...NO UPDATE.  PULSE SEVERE THUNDERSTORMS HAVE DROPPED
DIME SIZE HAIL OVER EASTERN ZONES ACCOMPANIED WITH RAIN AMOUNTS UP
TO AN INCH IN 2 HOURS.  THUNDERSTORMS HAVE ALSO PULSED ALONG
BOUNDARIES OVER THE WESTERN ZONES AS WELL.  REPORTS FROM EDMUNDS
COUNTY OF HIGH LEVEL COLD FUNNELS IN THE MID ATMOSPHERE AND LATER
SOME PEA-SIZE HAIL.  HAD A PUBLIC REPORT OF A TORNADO OVER WESTERN
STANLEY COUNTY THAT VELOCITY CROSS-SECTION SHOWED AS POSSIBLE...NO
VERIFICATION THOUGH FROM SPOTTERS IN THE AREA SO MAY HAVE BEEN A LOW
LEVEL COLD FUNNEL.  CURRENT FORECAST PACKAGE WITH OCCASIONAL SHOWERS
OR THUNDER IS WORKING WELL THIS EVENING.  RADAR SHOWS TOPS ARE
WARMING AND DYNAMICS ARE WEAKENING AS SUNSET APPROACHES.  CONVECTION
WILL CONTINUE THROUGH THE NIGHT BUT WITH LESS ENERGY.  MCNULTY

.LONG TERM...MONDAY THROUGH THURSDAY
MDLS IN GENERAL AGREEMENT WITH LONG-TERM PATTERN WITH INITIAL S/WV
PUSHING SOUTH OUT OF CANADA MONDAY NIGHT INTO TUESDAY. CAN/NOGAPS
LOOK A LITTLE MORE PROGRESSIVE WITH BRINGING THE SYSTEM THROUGH
EARLIER MONDAY...BUT AM LIKING THE LATER GFS AS SYSTEMS TEND TO SLOW
DOWN IN THE EXT. HOWEVER ALL MDLS AGREE IN KEEPING BEST DYNAMICS AND
MOISTURE TO THE NORTH OF THE ABR CWA. 12Z AVN IS SHOWING SOME DECENT
LL LIFT ACROSS CENTRAL SD AS THE FRONT MOVES THROUGH...BUT MOISTURE
SEEMS SOMEWHAT SCARCE. HAVE LEFT THAT TIME DRY FOR NOW...BUT WILL
CONTINUE TO MONITOR SYSTEM AS THIS TIME NEARS. ANOTHER VORT LOBE
ROTATING AROUND UPPER LOW IN CENTRAL CAN LOOKS TO SLIDE INTO THE NRN
PLAINS LATE TUE INTO WED. COULD SEE SOME SHRA POP UP IN SOUTHERLY
FLOW AHEAD OF THE SYSTEM...BUT A BETTER CHANCE FOR PRECIP WILL COME
WED AFTERNOON AS THE COLD FRONT SWINGS THROUGH. THEN REMAINDER OF
EXT LOOKS DRY. LOOKS LIKE COULD BE HEADING TOWARDS A PATTERN SWITCH
AS UPPER FLOW BECOMES MORE ZONAL INTO NEXT WEEK INSTEAD OF THE LARGE
WRN CONUS RIDGE. AS FAR AS TEMPS ARE CONCERNED...HAVE LEFT SIMILAR
TO PREVIOUS FCST AS THOSE VALUES CONTINUE TO LOOK ON TRACK.

.ABR...NONE.
