Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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, May 26, 3:10 PM CDT, 4 hours 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
310 PM CDT FRI MAY 26 2006

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...
MAIN PROBLEMS TODAY ARE CONVECTION TONIGHT AND SATURDAY NIGHT.
SURFACE TROUGH EXTENDS FROM WYOMING NORTHEAST TO WESTERN NORTH
DAKOTA. COLD FRONT IN EASTERN MONTANA WITH WARM FRONT EAST-WEST
THROUGH SOUTHERN NORTH DAKOTA. CONVECTION BEGINNING TO DEVELOP IN
EASTERN WYOMING AND EXPECT THIS SPREAD NORTH AND EAST THIS AFTERNOON
AND EVENING THOUGH 18Z SOUNDINGS FROM KGGW AND KUDX SHOW SIGNIFICANT
CAP STRENGTH STILL EVIDENT WITH CIN OF -135 AT BOTH SITES. SURFACE
WOBBLES BACK AND FORTH AS MID LEVEL SOUTHWEST FLOW REMAINS PARALLEL
TO SURFACE TROUGH BUT EVENTUALLY MOVES EAST OF CWA BY SUNDAY.
FORECAST  AREA REMAINS IN SLIGHT RISK BOTH THIS EVENING AND
TOMORROW.

SUNDAY SURFACE LOW MOVES SLOWLY EAST INTO MINNESOTA WITH MID LEVEL
TROUGH MOVING OVER WESTERN NORTH DAKOTA. CONTINUED SHOWERS AND
THUNDERSTORMS WITH CHANCE POPS BUT SIGNIFICANTLY COOLER TEMPS AS
THICKNESS FALLS FROM 582 EAST TO 555 NORTHWEST CORNER.

.LONG TERM...MONDAY THROUGH THURSDAY...
TUESDAY AND WEDNESDAY THE FORECAST AREA SHOULD SEE ZONAL FLOW ALOFT
ACROSS THE FORECAST AREA WITH GOOD SURFACE MOISTURE AND INSTABILITY

SLIGHT CHANCE OF TSTMS THROUGH THE FORECAST PERIOD.  MODELS HAVE
UNDERGONE A CHANCE IN THE PAST 24 HOURS AND NOW INDICATE A UPPER
LEVEL RIDGE TO BUILD OVER THE ROCKIES BY THE END OF THE FORECAST
PERIOD. BUT THE TRANSITION IS SLOW...AND FOR NOW WILL KEEP A CHANCE
OF TSTMS OFF AND ON THURSDAY AND FRIDAY.  TEMPS SHOULD REMAIN ABOVE
NORMAL THROUGH THE PERIOD.
