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.

Bismarck Municip, ND (KBIS), launched 00:00Z, 11.2 hours before the alert went out and 252 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, Jul 4, 3:39 AM CDT, 2 hours 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
339 AM CDT WED JUL 4 2012

.SHORT TERM...TODAY THROUGH THURSDAY...

COLD FRONT EXPECTED BE NEAR/ALONG A MINOT TO BISMARCK LINE AND INTO THE
JAMES RIVER VALLEY BY 18Z. EXPECTING ANY PRECIPITATION TO MAINLY BE
CONFINED IN THE NORTHEAST ZONES WITH A DRY FROPA ELSEWHERE.
HOWEVER WILL METWATCH CLOSELY AS THE HRRR HAS BEEN CONSISTENTLY
SHOWING SOME SOUTHWARD EXPANSION IN THE PRECIPITATION THROUGH THE
EARLY MORNING. OTHERWISE EXPECT BREEZY CONDITIONS BEHIND THE
FRONT WITH DRIER AIR/LOWER DEW POINTS ARRIVING DURING THE DAY. STILL
WARM TODAY WITH HIGHS BETWEEN 80F AND 90F. COOLER AND DRIER AIR
SETTLES OVER WESTERN AND CENTRAL NORTH DAKOTA TONIGHT WITH LOWS
BETWEEN 50F AND 60F. THE NEXT SHORTWAVE IS SCHEDULED TO APPROACH
OUR SOUTHERN ZONES THURSDAY WITH A SLIGHT CHC OF SHOWERS/THUNDERSTORMS
IN THE AFTERNOON. MORE SUBSTANTIAL PRECIPITATION SLATED FOR THURSDAY
NIGHT INTO FRIDAY.

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY...

NEXT SHORTWAVE TROUGH WITH AN ASSOCIATED SURFACE LOW WILL MOVE
ACROSS SOUTH DAKOTA THURSDAY NIGHT THROUGH FRIDAY NIGHT. IT
APPEARS THAT THE MODELS ARE COMING INTO DECENT AGREEMENT WITH AN
MCS EVENT...STARTING IN WYOMING/WESTERN SOUTH DAKOTA THURSDAY
NIGHT AND ROTATING NORTHEAST INTO SOUTHERN NORTH DAKOTA. THE
POTENTIAL OF WIDESPREAD 1 INCH RAINFALL AMOUNTS ALONG AND SOUTH
INTERSTATE 94 THURSDAY NIGHT THROUGH FRIDAY AFTERNOON LOOK
REASONABLE AND HAVE MADE LITTLE CHANGES TO THE HPC QPF AMOUNTS.
POSSIBLE TOTAL RAINFALL AMOUNTS NEAR THE BORDER COULD BE AROUND
1. 5 INCHES. THEREAFTER...THE UPPER LEVEL FLOW GRADUALLY BECOMES
NORTHWEST THROUGH EARLY NEXT WEEK AS THE CENTRAL PLAINS RIDGE
SHIFTS WEST. THIS WILL STILL ALLOW FOR RIDGE TOPPERS TO MOVE
THROUGH NORTH DAKOTA BUT LOW LEVEL MOISTURE WILL BE CONSIDERABLE
LESS AND AREAL COVERAGE OF PRECIPITATION SHOULD FOLLOW.

&&

.AVIATION...VFR CEILINGS/VISIBILITIES EXPECTED NEXT 24HR. POSSIBLE
LOW VFR CEILINGS AT KISN AND KMOT THROUGH 12Z WEDNESDAY. AN
ISOLATED SHOWER OR THUNDERSTORM CANNOT BE RULED OUT AT KJMS
THROUGH 00Z THURSDAY. SKIES WILL CLEAR WEDNESDAY NIGHT.

.BIS WATCHES/WARNINGS/ADVISORIES...
