What was reported inside it

Time	Report	Where	Remark
Jul 16, 9:00 AM CDT	HAIL 0.88	Wing, ND	DIME TO NICKEL SIZE HAIL... 4 TO 5 MINUTES IN DURATION...

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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 12:00Z, 1.9 hours before the alert went out and 78 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 16, 5:03 AM CDT, 3 hours 51 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
503 AM CDT SAT JUL 16 2011

.SHORT TERM...TODAY THROUGH SUNDAY AFTERNOON...

MAIN HIGHLIGHTS IN THE SHORT TERM PERIOD WILL CONTINUE TO BE
CHANCES FOR STRONG TO SEVERE THUNDERSTORMS AND HOT AND HUMID
WEATHER CONDITIONS. A MODEL BLEND WILL SUFFICE...BUT DID LEAN
AWAY FROM THE GFS/EC DEPICTIONS OF PRECIP CHANCES/QPF PLACEMENT.

CURRENTLY...SOUTHWEST FLOW ALOFT REMAINS OVER THE NORTHERN PLAINS
LEADING TO ANOTHER NIGHT OF NOCTURNAL CONVECTION. STORMS CONTINUE
TO BE MARGINALLY SEVERE THANKS TO UPPER LEVEL SUPPORT VIA THE
RIGHT ENTRANCE REGION OF AN UPPER JET STREAK...AND MID LEVEL
SUPPORT ON THE NOSE OF A LLJ. THIS ACTIVITY LOOKS TO BE MAINTAINED
TILL AROUND AND SHORTLY AFTER 12Z WHEN FORCING STARTS TO DIMINISH.

LOTS OF UNCERTAINTY AS TO THUNDERSTORM CHANCES LATER TODAY INTO
THIS EVENING. MODELS DEPICT A RATHER STRONG CAPPING INVERSION
HOLDING THROUGHOUT TODAY FOR MOST PLACES. THE EXCEPTION LOOKS TO
BE AROUND THE DEVILS LAKE BASIN AREA AS WELL AS ACROSS FAR SOUTH
CENTRAL CANADA WHERE THE CAP IS WEAKER AND WHERE MODELS SUGGEST A
MID LEVEL S/WV IMPULSE WILL TRACK. THE GFS AND ECMWF BOTH DEVELOP
PRECIP ACROSS MOST OF MY CENTRAL COUNTIES ALONG THE SFC TROUGH.
THINK THE BETTER CHANCES WILL BE OVER MY NORTHEAST AND EAST
CENTRAL...CLOSER TO WHERE THE 4KM WRF AND NAM INDICATE POSSIBLE
CONVECTION. WILL MENTION THE POSSIBILITY OF SEVERE STORMS.

THE OTHER HIGHLIGHT FOR TODAY WILL BE THE VERY WARM TEMPERATURES
COMBINED WITH SFC DEWPOINT TEMPS IN THE 60S TO MID 70S. RESULTANT
HEAT INDEX VALUES WILL BE OPPRESSIVE TO SAY THE LEAST ACROSS MY
CENTRAL COUNTIES. NOT AS WARM OR MOIST WEST ON THE BACKSIDE OF THE
TROUGH BUT STILL MUGGY. STILL THINK THE HIGHER DAYTIME TEMPS WILL
BE ALONG THE SFC TROUGH AXIS WHERE WE MAY SEE SOME BETTER SOUTH TO
SOUTHWESTERLY MIXING WINDS. THIS IS WHERE I PAINTED MID/UPPER 90S.
DO NOT THINK WE WILL SEE 100 GIVEN THE HIGH HUMIDITY...BUT CANNOT
RULE IT OUT ENTIRELY EITHER IF WE ARE ABLE TO MIX DOWN DRIER AIR
ALOFT.

CONTINUED WARM AND MUGGY TONIGHT...BUT UNLIKE THE LAST TWO NIGHTS
THE CHANCES FOR NOCTURNAL THUNDERSTORMS WILL BE LITTLE TO NONE
THANKS TO THE LACK OF A NOCTURNAL LLJ AND WEAKER SUPPORT ALOFT.

WARM FRONT SETTLES NEAR THE ND/SD BORDER AREA FOR SUNDAY...KEEPING
THE HOTTER TEMPERATURES SUNDAY AFTERNOON/EARLY EVENING MORE OVER
MY SOUTHERN COUNTIES. LOWERED TEMPS NORTH AND MAINTAINED MID/UPPER
90S SOUTH. MOIST EASTERLY FLOW WILL CONTRIBUTE TO WIDESPREAD
DEWPOINTS IN THE 70S FOR ALL BUT THE FAR NORTH AND WEST. HEAT
INDEX VALUES SUNDAY LOOK TO BE HIGHER SOUTH CENTRAL AND SOUTHEAST
THAN TODAY...AS WELL AS SOUTHWEST. LATER SHIFTS WILL NEED TO
CONSIDER ADDING PARTS OF SOUTHWESTERN NORTH DAKOTA INTO THE
EXCESSIVE HEAT WARNING OR INTRODUCE A HEAT ADVISORY. CHANCES FOR
THUNDERSTORMS SUNDAY DAYTIME WILL BE MINIMAL WITH THE UPPER LEVEL
RIDGE BUILDING FARTHER NORTH RESULTING IN A STRONG CAP.

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...

OVERALL WEATHER PATTERN REMAINS ABOUT THE SAME WITH THE
SUBTROPICAL RIDGE ANCHORED OVER THE CENTRAL PLAINS. PRECIPITATION
CHANCES WILL AVERAGE ONLY IN THE SLIGHT CHANCE CATEGORY MONDAY AND
TUESDAY WITH MODELS CONTINUING TO DEPICT THE RIDGE FARTHER TO THE
NORTH RESULTING IN A STRONG CAPPING INVERSION PERSISTING OVER THE
DAKOTAS. THIS WILL ALSO CAUSE HOT AND MUGGY CONDITIONS TO CONTINUE
THROUGH TUESDAY. BY MID WEEK A POTENT UPPER LEVEL S/WV TROUGH WILL
EJECT EAST-NORTHEAST ACROSS THE ROCKIES AND INTO SOUTH CENTRAL
CANADA...PUSHING THE RIDGE FARTHER SOUTH FINALLY ALLOWING DRY
SURFACE HIGH PRESSURE TO BUILD EAST INTO THE REGION. THE PATTERN
THEN TRIES TO REESTABLISH BACK TO OUR CURRENT FLOW.

&&

.AVIATION...

CURRENTLY...WIDESPREAD SHOWERS AND THUNDERSTORMS ARE DEVELOPING
ACROSS THE WEST NEAR KISN/KMOT/KDIK. WITHIN THESE STORMS...EXPECT
MVFR CEILINGS...SMALL HAIL...FREQUENT CLOUD TO GROUND
LIGHTNING...BRIEF HEAVY DOWNPOURS...AND WINDS GUSTING UP TO 40 MPH.
THESE SHOWERS AND THUNDERSTORMS WILL POSSIBLY AFFECT KBIS BY 12 UTC.

VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGHOUT THE
PERIOD...EXCEPT FOR MVFR CEILINGS IN SHOWERS AND THUNDERSTORMS...AS
WELL AS SOME PERIODS OF MVFR/IFR POSSIBLY AT KJMS/KBIS...WHERE
SCATTERED FOG MAY DEVELOP. THUNDERSTORMS MAY REDEVELOP LATER IN THE
PERIOD...AFTER 18 UTC...BUT THERE IS HIGH UNCERTAINTY TO WHETHER OR
NOT REDEVELOPMENT OCCURS.
