Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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 12:00Z, 10.4 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
NATIONAL WEATHER SERVICE BISMARCK ND
350 PM CDT THU AUG 24 2006

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT...
LARGE SURFACE LOW CENTERED OVER NORTH CENTRAL SOUTH DAKOTA WITH
BROAD LOW PRESSURE EXTENDING FROM WESTERN MANITOBA THROUGH THE
DAKOTAS THIS AFTERNOON. UPPER LEVEL SHORTWAVES WITH GOOD VORTICITY
ENERGY OVER NORTH CENTRAL NORTH DAKOTA AND ANOTHER OVER SOUTHWESTERN
NORTH DAKOTA AT THIS TIME. CLUSTER/LINE OF THUNDERSTORMS ASSOCIATED
WITH THE UPPER LEVEL SHORTWAVES COVERING MOST OF CENTRAL NORTH

TONIGHT WILL KEEP A CHANCE OF THUNDERSTORMS OVER CENTRAL NORTH
DAKOTA LATE TONIGHT. WILL ALLOW THE FLASH FLOOD WATCH TO EXPIRE.

EXPECT HIGHS ONLY IN THE 70S ON FRIDAY WITH SOME CYCLONIC FLOW ALOFT
AND WEAK SURFACE HIGH. MODELS INDICATE ANOTHER UPPER SHORTWAVE
MOVING INTO SOUTHWESTERN NORTH DAKOTA ON FRIDAY...SO KEPT SMALL
CHANCE OF THUNDERSTORMS THERE - SIMILAR TO PREVIOUS FORECAST.

SATURDAY AND SUNDAY ZONAL UPPER LEVEL FLOW WITH WITH WEAK HIGH
PRESSURE OVER THE STATE. DRY CONDITIONS FORECAST WITH SEASONAL
TEMPERATURES.

.LONG TERM...MONDAY THROUGH THURSDAY NIGHT...
MONDAY AND TUESDAY UPPER LEVEL RIDGE BUILDS INTO THE NORTHERN
