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.

What forecasters said that day

The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Bismarck, ND wrote its last area forecast discussion before this tornado warning went out at Jun 25, 3:06 PM CDT, 3 hours 25 minutes earlier.

Area forecast discussion, Jun 25, 3:06 PM CDT, 3 hours 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
306 PM CDT FRI JUN 25 2010

.SHORT TERM...TONIGHT THROUGH MONDAY NIGHT..
MULTIPLE OUTFLOW BOUNDARIES REMAIN IN PLACE ACROSS SOUTHERN NORTH
DAKOTA FRIDAY AFTERNOON. A SURFACE TROUGH REMAINS IN PLACE ACROSS
EASTERN MONTANA. ATMOSPHERE VERY UNSTABLE WITH AREAS OF CONVECTION
ONGOING BUT BELOW SEVERE LIMITS AT THIS TIME. ANTICIPATING
SHORTWAVE ENERGY TO MOVE UP THE WESTERN RIDGE AXIS INTO NORTH
DAKOTA LATE THIS AFTERNOON AND THIS EVENING WITH OUTFLOW BOUNDARIES
AND SURFACE TROUGH ALONG MONTANA/NORTH DAKOTA BORDER BEING THE
FOCAL POINTS FOR SIGNIFICANT CONVECTION LATER THIS EVENING AND
OVERNIGHT.

ADDITIONAL THUNDERSTORMS ARE EXPECTED SATURDAY AFTERNOON AND
EVENING ACROSS CENTRAL NORTH DAKOTA AS THE UPPER SHORTWAVE TROUGH
MOVES THROUGH. BY SUNDAY AND MONDAY THE REGION WILL FINALLY BE
UNDER THE INFLUENCE OF AN UPPER RIDGE...BRINGING WARMER
TEMPERATURES AND DRY WEATHER.

.LONG TERM...TUESDAY THROUGH FRIDAY NIGHT...
FORECAST CHALLENGE IN THE LONG TERM WILL BE FIGURING OUT THE
TIMELINE ON THE BREAKDOWN AND/OR SHIFT OF THE CENTRAL PLAINS UPPER
LEVEL RIDGE WHICH AMPLIFIES OVER THE NORTHERN PLAINS BEGINNING
TUESDAY. THE GFS HAS BEEN CONSISTENT IN HOLDING THE RIDGE IN PLACE
THROUGH THURSDAY BEFORE SHIFTING IT EASTWARD. THE ECMWF HAS BEEN
CONSISTENT WITH A QUICKER SHIFT...SHIFTING IT EAST BY TUESDAY
EVENING. THE ECMWF SCENARIO WOULD CERTAINLY OPEN UP A SOUTHWEST FLOW
WITH MULTIPLE SHORTWAVE TROUGHS LINING UP AND HEADING INTO THE
NORTHERN HIGH PLAINS. THE GFS SOLUTION WOULD AT LEAST KEEP THE
SHORTWAVES AWAY FROM WESTERN AND CENTRAL NORTH DAKOTA THROUGH
THURSDAY. HAVE WEIGHTED THE GFS SOLUTION MORE HEAVILY WITH A SLOWER
EASTWARD SHIFT OF THE RIDGE PER HPC GRIDS. EXPECTING DRY WEATHER
TUESDAY THROUGH THURSDAY THEN INTRODUCED A SLIGHT CHANCE FOR
THUNDERSTORMS THURSDAY NIGHT THROUGH FRIDAY NIGHT AS SHORTWAVES
MIGRATING THROUGH. TEMPERATURES WILL WARM THROUGH THE PERIOD WITH
MID AND UPPER 80S FOR AFTERNOON HIGHS AND OVERNIGHT LOWS IN THE
UPPER 50S TO MID 60S.

.AVIATION...SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE FRIDAY
AFTERNOON THROUGH SATURDAY EVENING. VFR CONDITIONS WILL DOMINATE
OUTSIDE OF ANY SHOWERS AND THUNDERSTORMS. HOWEVER WITH ANY HEAVY
DOWNPOURS OR SEVER WEATHER ASSOCIATED WITH THE STRONGER
THUNDERSTORMS AERODROMES MAY EXPERIENCE A BRIEF PERIOD OF MVFR
CEILINGS AND VISIBILITIES.

.BIS WATCHES/WARNINGS/ADVISORIES...
