The radar

The Minot AFB radar (KMBX), 64 km from the middle of the area, began a volume at 04:40 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

Bismarck Municip, ND (KBIS), launched 00:00Z, 4.6 hours before the alert went out and 243 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, Sep 18, 10:55 PM CDT, 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
1055 PM CDT WED SEP 18 2013

.UPDATE...
ISSUED AT 1056 PM CDT WED SEP 18 2013

UPDATE TO CLEAR LOGAN AND MCINTOSH COUNTIES FROM SEVERE
THUNDERSTORM WATCH. ALSO INCREASED POPS AND ADDED AREAS OF FOG
OVER THE NORTH CENTRAL.

UPDATE ISSUED AT 1005 PM CDT WED SEP 18 2013

CANCELLED SEVERE THUNDERSTORM WATCH #527 FOR SIOUX AND EMMONS
COUNTIES IN SOUTH CENTRAL NORTH DAKOTA. BOWING LINE SEGMENT
CONTINUES OVER MCINTOSH AND DICKEY COUNTIES AND WILL KEEP THE
WATCH IN EFFECT FOR THE FAR SOUTHEAST CWA.

THUNDERSTORMS ALSO CONTINUE OVER THE NORTHWEST...BUT THESE HAVE
DECREASED IN INTENSITY OVER THE PAST HOUR. UPDATE CLEARED WATCH
AND UPPED POPS IN THE SOUTHEAST CWA WHERE CONVECTION IS ONGOING.

UPDATE ISSUED AT 822 PM CDT WED SEP 18 2013

SEVERE THUNDERSTORM WATCH CONTINUES FOR THE SOUTHEAST PART OF THE
FORECAST AREA...SIOUX...EMMONS...LOGAN...MCINTOSH...LAMOURE...AND
DICKEY COUNTIES UNTIL MIDNIGHT CDT. CONVECTION JUST SOUTH OF THE
NORTH AND SOUTH DAKOTA STATE LINE WAS MOVING EAST-NORTHEAST...
TOWARD THE WATCH BOX AREA.

OTHER CONVECTION WAS OVER THE NORTHWEST...NORTH OF WILLISTON...AND
MOVING NORTHEAST...WHILE A THIRD AREA OF CONVECTION WAS NORTH OF
BEACH...ALSO MOVING NORTHEAST.

HAVE MAINTAINED POPS AS PREVIOUS FORECAST REFLECTING THE HIGHEST
CHANCES IN THE NORTHWEST AND THE SOUTHEAST PARTS OF THE FORECAST AREA.

WE DID INCREASE WINDS LATER TONIGHT AND DURING THE DAY THURSDAY
BASED ON LATEST GUIDANCE AND CURRENT CONDITIONS UPSTREAM...THAT
WILL BE INTO NORTH DAKOTA THURSDAY. THE SPEEDS WILL BE BORDERLINE
ADVISORY CRITERIA OVER SOUTHWEST NORTH DAKOTA AND THIS WILL BE
REEVALUATED FOR A FUTURE FORECAST ISSUANCE.

UPDATE ISSUED AT 605 PM CDT WED SEP 18 2013

UPDATE EARLY THIS EVENING FOR THUNDERSTORMS OVER NORTHWEST AND
SOUTHEAST PORTIONS OF THE CWA. SPC HAS EXTENDED THE CURRENT SEVERE
THUNDERSTORM WATCH EAST TO INCLUDE DICKEY AND LAMOURE COUNTIES.
CONVECTION HAS DEVELOPED NEAR THE SURFACE LOW. VERY MOIST AND
UNSTABLE AIRMASS REMAINS IN THIS AREA. ALTHOUGH WATCH IS A SEVERE
THUNDERSTORMS...THINK THE TORNADO THREAT WOULD BE HIGHER NEAR THIS
AREA. FARTHER WEST...CONVECTION MOVING THROUGH WESTERN SOUTH
DAKOTA MAY CLIP THE SOUTH CENTRAL. WITH STRONG BULK SHEAR
INCREASING HERE...THE THREAT OF STRONG WINDS AND LARGE HAIL
APPEARS HIGHER HERE. CONVECTION IN THE NORTHWEST WILL NEED TO BE
MONITORED WITH UPPER LEVEL SYSTEM APPROACHING...BUT IT APPEARS TO
BE DIMINISHING AS IT LIFTS FARTHER NORTH.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 255 PM CDT WED SEP 18 2013

THE MAIN FORECAST CONCERN DURING THE SHORT TERM PERIOD IS
CONVECTIVE TRENDS AND SEVERE WEATHER POTENTIAL THROUGH TONIGHT.
LATEST THINKING IS CLEARING ACROSS THE FAR SOUTHEAST WILL PROVIDE
AT LEAST A BRIEF WINDOW THIS EVENING FOR SEVERE WEATHER NEAR THE
WARM FRONT/SURFACE LOW...WITH ENHANCED LOW LEVEL SHEAR PROVIDING
THE CHANCE OF AN ISOLATED TORNADO.

TO THE WEST...THERE IS STILL CONSIDERABLE UNCERTAINTY. WHILE DEEP
LAYER SHEAR IS FAVORABLE...MOISTURE/INSTABILITY ARE NOT AS
IMPRESSIVE. HIGH RESOLUTION SHORT TERM MODELS SUGGEST POTENTIAL
FOR STORMS TO MOVE INTO FAR SOUTHWEST NORTH DAKOTA...THEN PUSH
EAST ALONG THE BORDER. WIDESPREAD SEVERE WEATHER IS NOT
ANTICIPATED OVER CENTRAL AND WESTERN COUNTIES...BUT WE WILL LIKELY
HAVE A FEW STRONG TO NEAR SEVERE STORMS TO MONITOR TONIGHT. TOWARD
DAYBREAK THURSDAY...THE TRAILING COLD FRONT AND MAIN UPPER TROUGH
WILL PUSH INTO THE STATE. EXPECT LOW CLOUDS...SCATTERED SHOWERS
AND A GUSTY WEST WIND. THE STRONGEST GRADIENT WILL LIKELY BE
ACROSS THE SOUTHWEST...BUT NOT ANTICIPATING ADVISORY LEVEL WINDS
AT THIS TIME. AFTERNOON TEMPERATURES WILL BE MUCH COOLER
THURSDAY...WITH HIGHS FROM THE UPPER 50S TO UPPER 60S.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 255 PM CDT WED SEP 18 2013

MODELS ARE IN GOOD AGREEMENT EARLY IN THE PERIOD BUT BEGIN TO
DIVERGE SLIGHTLY EARLY NEXT WEEK. EXTENDED PERIOD BEGINS WITH
PROGRESSIVE TROUGH OVERHEAD PUSHING EASTWARD. RIDGE BUILDS IN
THROUGH THE WEEKEND BRINGING CONTINUED DRY AND MILD TEMPERATURES
ACROSS THE STATE. TEMPERATURES INITIALLY IN THE 60S ON FRIDAY WILL
WARM TO THE 70S OVER THE WEEKEND AND INTO EARLY NEXT WEEK.
GFS/ECMWF DIFFERENCES BEGIN TO INCREASE BY MONDAY AS THE RIDGE
SHIFTS TO THE GREAT LAKES REGION WITH A TROUGH APPROACHING THE
NORTHERN PLAINS AND BRINGING THE NEXT CHANCE OF PRECIPITATION
BEGINNING SUNDAY NIGHT. BY TUESDAY THE GFS DEVELOPS A BROAD
CYCLONIC FLOW ACROSS MUCH OF WESTERN NORTH AMERICA WHILE THE ECMWF
HOLDS A SHARPER LONGWAVE TROUGH ALONG THE WESTERN NORTH AMERICAN
COAST. HOWEVER...BOTH MODELS DO BRING CLOSED UPPER LOW TO GREAT
BASIN BY WEDNESDAY PLACING OUR REGION IN SOUTHWEST FLOW ALOFT.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 1056 PM CDT WED SEP 18 2013

VFR CONDITIONS TO START THE TAFS OFF. BUT MVFR CEILINGS REMAIN A
POSSIBILITY ACROSS THE NORTH THIS EVENING. CONVECTION IS POSSIBLE
OVER THE SOUTHERN TAF SITES THIS EVENING. LATE TONIGHT AS LOW
PRESSURE MOVES EAST...WRAP AROUND MOISTURE WILL DROP SOUTH ACROSS
THE AREA BRINGING MVFR TO IFR CEILING NORTH TO SOUTH ACROSS THE
AREA THROUGH MID MORNING. ADDED AREAS OF FOG AT KMOT AS VISIBILITY
HAS RAPIDLY DECREASED TO A QUARTER MILE.

.BIS WATCHES/WARNINGS/ADVISORIES...
NONE.
