Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 29 minutes after it went out.

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, 5.5 hours before the alert went out and 176 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, Jun 19, 11:34 PM CDT, 57 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
1134 PM CDT WED JUN 19 2013

.UPDATE...
ISSUED AT 1125 PM CDT WED JUN 19 2013

THERE WILL BE NO MAJOR CHANGES TO THIS UPDATE. GETTING MORE ROBUST
ELEVATED CONVECTION DEVELOPING IN OUR WESTERN AREAS AND AS
PREVIOUSLY THOUGHT...THIS ACTIVITY WILL SLOWLY SPREAD NORTH AND
EAST OVERNIGHT. CAN/T RULE OUT A STRONG TO LOCALLY SEVERE HAIL
EVENT OVERNIGHT...AND LOCALLY HEAVY RAIN WITH FAIRLY SLOW MOVING STORMS.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY NIGHT)
ISSUED AT 306 PM CDT WED JUN 19 2013

MAIN ISSUE THROUGHOUT THE PERIOD WILL BE CHANCES AND STRENGTH OF
CONVECTION.

WV LOOP AND UPPER AIR ANALYSIS HAVE THE MAIN RIDGE OVER THE
NORTHERN PLAINS...ALTHOUGH THERE ARE SOME WEAK EMBEDDED SHORTWAVES
MOVING THROUGH THE DAKOTAS UNDER THE RIDGE AXIS. SOUTHEASTERLY
WINDS HAVE DEVELOPED OVER THE SOUTHERN AND WESTERN CWA ALONG THE
FRONT SIDE OF A SFC TROUGH EXTENDING FROM SOUTHERN ALBERTA INTO
WESTERN SD. MANY OF THE MODELS HAVE CONVECTION MOVING INTO OUR
SOUTHERN COUNTIES TONIGHT ALONG THE SHORTWAVE CURRENTLY MOVING
THROUGH SD. THERE HAS BEEN SOME DECENT CU DEVELOPING TO OUR SOUTH
AND WEST. MODELS HAVE BEEN OVERESTIMATING SFC MOISTURE
THOUGH...PARTICULARLY THE GFS AND NAM WHICH HAVE DEW POINTS THIS
AFTERNOON IN THE MID 60S AND THEY HAVE BEEN IN THE 50S IN REALITY.
THINK THERE WILL BE SOME SCATTERED THUNDERSTORM ACTIVITY TONIGHT
AS THAT WEAK SHORTWAVE COMES OUT. HOWEVER...WITH VERY WEAK SHEAR
DO NOT THINK THERE WILL BE MUCH IN THE WAY OF SEVERE.

ANOTHER WEAK SHORTWAVE TROUGH WILL BE LIFTING INTO THE NORTHERN
PLAINS TOMORROW. MUCH OF THE DEVELOPMENT TOMORROW WILL DEPEND ON
EXACTLY HOW CONVECTION TONIGHT PLAYS OUT. THINK THERE SHOULD BE
ENOUGH CLEARING FOR DESTABILIZATION. WITH CONTINUED SOUTHEASTERLY
WINDS THERE SHOULD BE BETTER MOISTURE...ALTHOUGH THE NAM AND GFS
HAVE NEAR 70 DEW POINTS AND ARE PROBABLY OVERESTIMATING. WILL
CONTINUE TO KEEP HIGH POPS AND WITH THE POSSIBILITY OF 2000 J/KG
OF CAPE THERE COULD BE SOME ACTIVITY THAT BECOMES SEVERE THURSDAY
AFTERNOON. THE CONVECTION WILL CONTINUE TO MOVE EASTWARD THROUGH
THE MN COUNTIES THROUGH THURSDAY NIGHT SO KEPT POPS HIGH.

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 306 PM CDT WED JUN 19 2013

THE CHANCES FOR CONVECTION CONTINUE THROUGH FRIDAY AND SATURDAY
AS SOUTHWESTERLY FLOW ALOFT CONTINUES ALONG WITH MINOR SHORTWAVES.
IT IS DIFFICULT TO PINPOINT SUCH SMALL SCALE FEATURES THIS FAR
OUT. HOWEVER...MOST OF THE MODELS SEEM TO BE LATCHING ONTO A MORE
SIGNIFICANT SHORTWAVE COMING THROUGH FRIDAY NIGHT AND SATURDAY.
THUS...KEPT POPS A BIT HIGHER DURING THAT PERIOD THAN DURING THE
DAY ON FRIDAY WHERE THERE COULD BE A BIT OF A LULL IN ACTIVITY
ALTHOUGH COMPLETELY DRY IS NOT GUARANTEED. TEMPS WILL CONTINUE TO
BE WARM WITH HIGHS IN THE UPPER 70S TO 80S AND LOWS IN THE 60S.

SATURDAY NIGHT-WEDNESDAY...
AN ACTIVE WEATHER PATTERN WILL CONTINUE ACROSS THE NORTHERN PLAINS
DURING THIS PERIOD. THE 12Z GFS/ECMWF ARE IN GENERAL AGREEMENT IN
LIFTING THE MAIN TROUGH TOWARDS THE SOUTHERN CANADIAN PRAIRIES ON
SUNDAY...WHILE THE GEM IS MUCH FARTHER SOUTH. BY MONDAY...THE
OPERATIONAL MODELS SUGGEST A MORE ZONAL FLOW PATTERN
DEVELOPING...WITH THE ECMWF SHOWING THE FORECAST AREA ON THE
PERIPHERY OF A DEVELOPING MID/UPPER LEVEL RIDGE ACROSS THE HIGH
PLAINS BY THE MIDDLE OF NEXT WEEK. TEMPERATURES WILL CONTINUE TO
REMAIN NEAR OR A BIT ABOVE NORMAL...WITH HIGHS IN THE 70S AND
80S...AND LOWS IN THE 50S AND 60S.

MAINTAINED SOME POPS THROUGH MOST PERIODS...AS CONFIDENCE IS LOW ON
TIMING PRECIP CHANCES DURING ANY GIVEN PERIOD. AT THIS POINT THE
BEST RAIN CHANCES APPEAR TO BE WITH THE PASSAGE OF THE UPPER TROUGH
SAT NIGHT INTO SUNDAY. THEREAFTER...THE TIMING OF EMBEDDED SHORTWAVE
TROUGHS IN THE QUASI-ZONAL FLOW AND THE LOCATION OF LOW-LEVEL
BOUNDARIES/GREATER MOISTURE TRANSPORT WILL DETERMINE WHERE/WHEN
BETTER RAIN CHANCES WILL BE.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 1125 PM CDT WED JUN 19 2013

THE CHANCES FOR SHOWERS AND THUNDERSTORMS WILL INCREASE FROM WEST
TO EAST OVERNIGHT AND THURSDAY. HAVE STARTED TO MENTION SOME
CONVECTION...ALTHOUGH TIMING REMAINS TOUGH. FOR NOW HAVE KEPT ALL
CIGS IN VFR CATEGORY...AND WILL CONTINUE TO REVISE FORECAST ONCE
TIMING AND AREAL COVERAGE BECOMES A BIT MORE CERTAIN.
