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.

The nearest sounding before it

Bismarck Municip, ND (KBIS), launched 00:00Z, 7.8 hours before the alert went out and 152 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jun 19, 2:30 PM MDT, 11 hours 19 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
330 PM CDT SUN JUN 19 2005

.SHORT TERM...
TONIGHT THROUGH WEDNESDAY NIGHT...MAIN FORECAST PROBLEM IS
PRECIPITATION CHANCES THROUGH THE PERIOD.

WEAK COLD FRONT ACROSS SOUTHERN ND WILL REMAIN IN THIS PROXIMITY
TONIGHT INTO MONDAY. CAP LOOKS STRONG ACROSS SOUTHEAST ND WHERE
CLOUD COVER ATTESTS TO THE MID LEVEL INVERSION AT BIS/ABR. EXPECT
ANOTHER NOCTURNAL EVENT AND WITH MID LEVEL LAPSE RATES NEAR
ADIABATIC ANOTHER CHC FOR LARGE HAIL/STRONG WINDS A POSSIBILITY.
HOWEVER WITH STRONG CAP WILL NEED TO HAVE SOME HELP WITH LOW LEVEL
NOCTURNAL JET. EXPECT THE THUNDERSTORMS TO END DURING THE MORNING
HOURS...THEN ANOTHER NOCTURNAL EVENT MONDAY NIGHT INTO TUESDAY
MORNING. AS RIDGE BUILDS INTO THE NORTHERN PLAINS BY WEDNESDAY
EXPECT WARM TEMPS INTO THE 90S AS BROAD SOUTHERLY FLOW CONTINUES TO
BRING WARM AIR INTO THE REGION. THE CAP MAY LIMIT THE CHC OF
THUNDERSTORMS BUT A SLIGHT CHC CANT BE RULED OUT.

.LONG TERM...
THURSDAY THROUGH SUNDAY
A SHORT WAVE MOVING THROUGH SOUTHERN CANADA ON THURSDAY WILL
CONTINUE TO CREATE UNSTABLE CONDITIONS...AND WILL KEEP A CHANCE OF
THUNDERSTORMS IN THE FORECAST. FRIDAY THE ASSOCIATED SURFACE LOW
WILL BE IN ONTARIO WITH WEST TO NORTHWEST WINDS ACROSS THE STATE.
THIS SHOULD PULL IN DRIER AIR AND LESSEN THE CHANCE OF TSTMS.
SATURDAY ANOTHER LEE SIDE TROUGH WILL DEVELOP AND MOVE TO EASTERN
MONTANA/WESTERN NORTH DAKOTA AS THE WINDS ALOFT BACK WITH THE
APPROACH OF YET ANOTHER UPPER LEVEL LOW.  THE ASSOCIATED SURFACE LOW
MOVES ACROSS THE CENTRAL PLAINS ON SUNDAY AND MONDAY...WITH BEST
CHANCE OF SIGNIFICANT WX TO THE SOUTH...SO WILL HOLD OFF ON ADDING
PRECIP TO THE FORECAST.  TEMPERATURES CONTINUE TO LOOK SEASONABLE
THROUGH THE PERIOD.
