What was reported inside it

Time	Report	Where	Remark
Aug 2, 5:45 PM CDT	TSTM WND GST 50	5 Ssw New Johns Lake, ND	STORM SPOTTER ESTIMATES WINDS AROUND 50MPH.

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, 10.7 hours before the alert went out and 79 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Bismarck, ND wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 2, 2:50 PM CDT, 2 hours 52 minutes earlier.

Area forecast discussion, Aug 2, 2:50 PM CDT, 2 hours 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
250 PM CDT THU AUG 2 2012

.SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT.  THE MAIN FORECAST
CONCERN WILL BE THE CHANCE OF THUNDERSTORMS.  AFTERNOON RADAR MOSAIC
SHOWS SHOWERS AND A FEW THUNDERSTORMS ACROSS PARTS OF EASTERN
MONTANA AND FAR WESTERN NORTH DAKOTA.  A FEW STRONG STORMS HAVE BEEN
SEEN ACROSS PARTS OF EASTERN MONTANA WHERE 100MB MLCAPE VALUES OF
1000-1500 J/KG ARE IN PLACE. EARLIER...THE STORMS WEAKENED A BIT
AS THEY MOVED EAST...BUT THAT TREND MAY NOT LAST WITH INCREASING
INSTABLITY ACROSS PARTS OF WESTERN NORTH DAKOTA.

THUNDERSTORMS WILL CONTINUE TO DEVELOP/MOVE OUT OF EASTERN
MONTANA TONIGHT IN ADVANCE OF AN UPPER LOW CURRENTLY LOCATED
ACROSS PARTS OF ALBERTA. SOME OF THE THUNDERSTORMS COULD BE
SEVERE...ESPECIALLY IN WESTERN PARTS OF NORTH DAKOTA WHERE THE
INSTABILITY WILL BE THE GREATEST. THE LOW LEVEL JET IS EXPECTED TO
INCREASE TONIGHT...WITH THE NOSE OF THE JET PUSHING INTO PARTS OF
SOUTHERN NORTH DAKOTA LATE TONIGHT. THIS SHOULD HELP KEEP
THUNDERSTORMS GOING THROUGH THE OVERNIGHT HOURS...HOWEVER THE
STORMS MAY DIMINSIH TO SOME DEGREE FRIDAY MORNING AS THE LOW
LEVEL JET BEGINS TO WEAKEN.

AS THE UPPER LOW MOVES SOUTHEAST TONIGHT INTO FRIDAY...IT WILL PUSH
A COLD FRONT ACROSS THE REGION. THE FRONTAL POSITION WILL A KEY FACTOR
IN DETERMINGING WHERE ADDITIONAL CONVECTION WILL FIRE ON FRIDAY
AFTERNOON. PRESENTLY IT APPEARS THE BOUNDARY SHOULD BE SOMEWHERE
FROM NEAR ROLLETTE-WISHEK BY EARLY AFTERNOON. THIS WILL CONFINE
THE MAIN SEVERE WEATHER THREAT TO THE EASTERN PART OF THE FORECAST
AREA...AND THIS IS IN LINE WITH THE CURRENT SPC DAY 2 OUTLOOK.

.LONG TERM...SATURDAY THROUGH NEXT THURSDAY...

THE EXTENDED PERIOD BEGINS WITH A SECONDARY COLD FRONT ADVECTING
SOUTH ACROSS THE NORTHERN PLAINS AND A STRONG UPPER LEVEL LOW
PROPAGATING EAST FROM EASTERN NORTH DAKOTA INTO WESTERN MINNESOTA.
WRAP AROUND PRECIPITATION...ESPECIALLY ACROSS THE NORTH...SATURDAY
MORNING LOOKING MORE AND MORE LIKELY WITH MODELS DEVELOPING A DECENT
TROWAL WRAPPING AROUND THE LOW AND PUNCHING SOUTH FROM SOUTH CENTRAL
CANADA INTO NORTHERN NORTH DAKOTA. MODELS DO DIFFER ON THE MAGNITUDE
OF THIS FEATURE ALONG WITH THE EASTWARD PROPAGATION OF THE UPPER
LOW. WILL KEEP LIKELY POPS NORTH WHERE MODELS SEEM TO BEST AGREE ON
WITH LESSER CHANCES FARTHER SOUTH DUE TO MORE UNCERTAINTY. WILL
CONTINUE WITH ALL SHOWERS AND NO THUNDER SATURDAY DAYTIME WITH
LITTLE IF ANY CAPE STILL DEPICTED BY GUIDANCE.

CLOUDS...PRECIP...AND STRONG CAA ASSOCIATED WITH THE LOW WILL KEEP
HIGHS COOL SATURDAY AND WELL BELOW AVERAGE...FROM AROUND 70 TO 75
MOST LOCATIONS. SOME LOCATIONS MAY STRUGGLE TO BREAK 65 DEPENDING ON
THE DURATION OF CLOUD COVER AND PRECIPITATION. BREEZY AS WELL ACROSS
THE CWA BUT AT THIS TIME IS EXPECTED TO BE BELOW WIND ADVISORY
CRITERIA AS THE PRESSURE GRADIENT FORCING DOES NOT LOOK TOO
IMPRESSIVE.

HIGH PRESSURE BUILDING INTO THE DAKOTAS IN THE LOWS WAKE WILL
QUICKLY DRY THINGS OUT SATURDAY NIGHT WITH DRY CONDITIONS PERSISTING
THROUGH SUNDAY NIGHT. LOWS SUNDAY MORNING WILL BE RELATIVELY CHILLY
THANKS TO THE EXPECTED CLEAR SKIES AND LIGHT WINDS ASSOCIATED WITH
THE SFC HIGH...FROM THE MID 40S TO LOW 50S. SURFACE HIGH PRESSURE
MOVES EAST SUNDAY RESULTING IN INCREASING RETURN FLOW/WAA. HIGHS
SUNDAY SHOULD BE ABOUT 10-15 DEGREES WARMER THAN SATURDAY.

NORTHWESTERLY FLOW ALOFT IS STILL DEPICTED NEXT WEEK MON-THURS WITH
THE UPPER RIDGE STRETCHED OUT ACROSS THE ROCKIES AND A LONG WAVE
TROUGH OFF TO OUR EAST. THIS SHOULD KEEP THE REAL WARM AIR WEST AND
SOUTH OF THE STATE WITH HIGHS AND LOWS NEAR NORMAL. MODELS DO TRY TO
MOVE THE RIDGE FARTHER EAST MID WEEK...WHICH WOULD PRODUCE A SLIGHT
WARMING TREND TO ABOVE NORMAL TEMPERATURES. WILL ALSO MAINTAIN A DRY
FORECAST MOST PERIODS MONDAY-THURSDAY. MODELS ARE KEYING IN ON A
SUBTLE IMPULSE CUTTING ACROSS THE NORTHERN PLAINS TUESDAY/TUESDAY
NIGHT...SO OPTED TO KEEP THE ALLBLEND GUIDANCE OF SLIGHT CHANCE POPS
WEST TUESDAY DAYTIME...AND AREA WIDE TUESDAY NIGHT. WHILE IT IS
POSSIBLE ANOTHER WEAK EMBEDDED WAVE IN NORTHWEST FLOW ALOFT COULD
DEVELOP ISOLD-SCT SHOWERS/THUNDER...TOO UNCERTAIN RIGHT NOW TO
INTRODUCE ANY OTHER WEATHER INTO THE FORECAST.

&&

.AVIATION...SURFACE HIGH PRESSURE WILL CONTINUE TO MOVE EAST
TODAY AS LOW PRESSURE DEVELOPS INTO THE WESTERN DAKOTAS LATER THIS
AFTERNOON...AND INTO THE CENTRAL DAKOTAS TONIGHT. VFR CONDITIONS
WILL CONTINUE THIS AFTERNOON FOR MOST LOCATIONS ALONG WITH LIGHT
AND VARIABLE WINDS. INCREASING CLOUDS WEST ALONG WITH SCATTERED
SHOWERS AND THUNDERSTORMS NOW THROUGH 00Z...INCLUDING KISN AND
KDIK. MVFR OR LOWER CIGS/VIS POSSIBLE WITH ANY SHRA/TSRA WHICH
PASSES OVER A TERMINAL. CLOUDS WILL CONTINUE TO INCREASE CENTRAL
AND EAST LATE TODAY INTO TONIGHT AS THE SURFACE LOW MOVES INTO THE
REGION. SCATTERED THUNDERSTORMS WILL CONTINUE TO DEVELOP NEAR THE
SURFACE LOW AS WELL WITH POSSIBLE MVFR AND LOWER CIGS/VIS FOR
KMOT...KBIS AND KJMS THIS EVENING THROUGH THE OVERNIGHT. WILL
CONTINUE THE MENTION OF VCTS/VCSH DUE TO THE SCT NATURE OF THE
PRECIPITATION. WILL ISSUE TEMPO GROUPS AS NEEDED.

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