The radar

The Aberdeen radar (KABR), 123 km from the middle of the area, began a volume at 09:34 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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

Aberdeen, SD (KABR), launched 00:00Z, 9.6 hours before the alert went out and 185 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
348 AM CDT THU JUN 14 2012

.SHORT TERM...TODAY THROUGH FRIDAY AFTERNOON...

FORECAST HIGHLIGHTS IN THE SHORT TERM PERIOD WILL BE LINGERING
PRECIPITATION AND COOL TEMPERATURES TODAY ASSOCIATED WITH AN UPPER
LEVEL LOW...THEN ANOTHER ROUND OF THUNDERSTORMS FRIDAY. MODELS ARE
REASONABLY SIMILAR SO WENT WITH A BLEND OF GUIDANCE.

CURRENTLY...FOR THE SEVERE THUNDERSTORM WATCH...WILL EXPIRE THE
REMAINING COUNTIES WITH THIS FORECAST PACKAGE. THE OVERALL CHANCE
FOR AN ISOLATED SEVERE STORM ANY MORE THIS MORNING REMAINS LOW.
ADDITIONAL SHOWERS/CONVECTION CONTINUES TO TRACK NORTHEAST ACROSS
THE WEST AND CENTRAL. MAINLY SHOWERS NOW BUT CANNOT RULE OUT AN
ISOLATED THUNDERSTORM THROUGH 12Z.

POTENT UPPER LEVEL WAVE/MID LEVEL LOW PRESSURE SYSTEM WILL SLOWLY
TRACK EAST ACROSS FAR SOUTH CENTRAL CANADA TODAY. SHOULD SEE MOST
IF NOT ALL OF THE PRECIPITATION ACROSS SOUTHERN NORTH DAKOTA END
BY 12Z...WITH POST FRONTAL PRECIPITATION DEVELOPING NORTHWEST INTO
NORTH CENTRAL THIS MORNING AND AFTERNOON ALONG AND BEHIND A STRONG
SECONDARY COLD FRONT. WINDS BECOME RATHER GUSTY TODAY BEHIND THE
FROPA...BUT AT THIS TIME LOOKS MARGINAL AS FAR AS WIND ADVISORY
NUMBERS SO HELD OFF ON ANY HEADLINES. THE DAY SHIFT WILL WANT TO
DIGEST LATEST GUIDANCE IN CASE WIND HEADLINES BECOME WARRANTED.

WEAK MID LEVEL RIDGE/SFC HIGH PRESSURE BUILD ACROSS THE REGION
TONIGHT RESULTING IN DRY WEATHER AND LIGHT WINDS.

OUR FLOW QUICKLY TRANSITIONS TO SOUTHWESTERLY FOR FRIDAY AHEAD OF
YET ANOTHER STRONG MID/UPPER LEVEL S/WV. SEVERE WEATHER
PARAMETERS ONCE AGAIN WILL YIELD A THREAT FOR STRONG STORMS FRIDAY
INTO FRIDAY EVENING AS THE MID LEVEL LOW APPROACHES NORTH DAKOTA.

.LONG TERM...FRIDAY EVENING THROUGH WEDNESDAY NIGHT...

POTENT UPPER LEVEL WAVE/MID LEVEL CLOSED LOW WILL CONTINUE TO
LIFT ACROSS THE ROCKIES AND THROUGH THE NORTHERN PLAINS FRIDAY
NIGHT-SATURDAY BRINGING LIKELY SHOWERS AND THUNDERSTORMS TO MOST
LOCATIONS...ESPECIALLY FRIDAY EVENING AND OVERNIGHT EARLY SATURDAY
MORNING. SCALED BACK CONSIDERABLY ON POPS SATURDAY AFTERNOON WITH
DRY AIR PUNCHING INTO THE REGION FROM SOUTHWEST TO CENTRAL. LEFT
CHANCES IN EAST FOR LINGERING SHOWERS/THUNDER...AND CHANCES ACROSS
THE NORTH NEAR THE TRACK OF THE MID LEVEL LOW.

DRY CONDITIONS REGION WIDE SATURDAY NIGHT WITH A WEAK RIDGE PUSHING
ACROSS THE NORTHERN PLAINS. AFTERWARDS (SUN-WED)...OUR WEATHER
PATTERN RETURNS TO VERY ACTIVE AS THE UPPER LEVEL JET BECOMES
ORIENTATED OVER THE NORTHERN CONUS AND STEERS SEVERAL MID LEVEL
DISTURBANCES FROM ACROSS THE ROCKIES INTO THE NORTHERN PLAINS.
SHOULD SEE A GOOD CHANCE FOR PRECIPITATION EACH PERIOD.

TEMPERATURES WILL AVERAGE NEAR NORMAL THROUGH THIS
WEEKEND...TRENDING TO NEAR TO SLIGHTLY BELOW NORMAL MON-WED.

&&

.AVIATION...

AS THE MID LEVEL AND SURFACE LOW TRACK OUT OF SASKATCHEWAN AND
INTO MANITOBA TODAY...A WEST TO NORTHWEST WIND WILL INCREASE WITH
SURFACE SPEEDS OF 15 TO 30 KNOTS. THERE IS A CHANCE OF
SHOWERS...POSSIBLY A THUNDERSTORM...WITH THE HIGHER CHANCES ACROSS
NORTHERN TAF SITES...KISN AND KMOT. NO SEVERE THUNDERSTORMS ARE
FORECAST THROUGH 15/1200 UTC.
