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.

Area forecast discussion, Aug 13, 9:12 PM CDT, 6 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
912 PM CDT THU AUG 13 2009

.UPDATE...WV IMAGERY SHOWS PRONOUNCED SHORTWAVE MOVING THROUGH
WESTERN MONTANA SUPPORTING CONVECTION. 00Z BIS SOUNDING SHOWS
STRONG CAP IN PLACE WITH H7 TEMP AROUND 13C AND 142 J/KG OF CIN
KEEPING 2091 J/KG OF CAPE OUT OF REACH. CONVECTION UNDERWAY WELL
WEST AND SOUTH OF CWA. NORTHWEST PART OF STATE REMAINS IN SLIGHT
RISK OF SEVERE STORMS PER SPC...CONDITIONAL ON ONGOING CONVECTION
UPSTREAM REACHING ND FOR MAINLY A WIND THREAT. MODELS HAVE
STRUGGLED WITH DETAILS OVER OUR CWA WITH 18Z NAM GENERATING
CONVECTIVE PRECIP BASED ON OVERLY MOIST LOW LEVELS. INCOMING 00Z
NAM CONTINUES TO SHOW CONVECTION MAKING IT INTO NW ND AFTER
06Z...ALTHOUGH LOOKING A LITTLE WEAKER THAN COMPLEX THAT THE 18Z
NAM BROUGHT THROUGH. BOTTOM LINE IS THAT FORECAST HAS BEEN LEFT
ALONE WITH CHANCE POPS LOCATED OVER NORTHERN ZONES WHERE COMBINATION
OF ELEVATED INSTABILITY AND APPROACHING SHORTWAVE WILL BETTER
SUPPORT CONVECTIVE THREAT. SAVADEL
&&

.PREV DISCUSSION... /ISSUED 244 PM CDT THU AUG 13 2009/

SYNOPSIS...FLOW IS AMPLIFYING ACROSS THE NORTHERN TIER THANKS
TO A STRONG JET STREAK DIVING SOUTHWARD INTO THE BASE OF A
NORTHWESTERN TROUGH AND AN INTENSIFYING SHORTWAVE IN THE
WASHINGTON/OREGON/IDAHO TRISTATE. A SERIES OF SHORTWAVES EJECTING
INTO THE NORTHERN PLAINS WILL RESULT IN AN ACTIVE PRECIPITATION
PATTERN.

SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT
SHORTWAVES EMBEDDED IN MAIN BELT OF WESTERLIES ACROSS THE NORTHERN
TIER WILL ACT TO ENHANCE THE THERMAL GRADIENT PRESENT ACROSS NORTH
DAKOTA WHILE PRESENTING THE PROBLEM OF DECIDING WHEN AND WHERE
PRECIPITATION WILL FALL. IT SEEMS THAT TODAY WILL BE SIMILAR TO
YESTERDAY WITH A FEW AFTERNOON THUNDERSTORMS POSSIBLE ALONG THE
FRONTAL BOUNDARY FOLLOWED BY ADVECTION OF LOWER HEIGHTS ALOFT AND
MORE AREAL COVERAGE OF SHOWERS AND THUNDERSTORMS LATE EVENING
THROUGH FRIDAY MORNING. THE MAIN DIFFERENCE EVIDENT IS FRONTAL
POSITION...WHICH HAS SHIFTED ABOUT 100 MILES SOUTHEASTWARD IN THE
PAST 12 HOURS.

THE AIR MASS SOUTH OF THE FRONT SHOULD REMAIN VERY CAPPED TODAY.
DYNAMIC SUPPORT FROM THE SHORTWAVE PROBABLY WILL NOT ARRIVE UNTIL
LATE EVENING...AND LOOKS TO REMAIN OVER THE NORTHERN HALF OF THE
STATE.

SEVERAL SHORTWAVES ARE THEN FORECAST TO IMPACT THE AREA FRIDAY INTO
EARLY SUNDAY MORNING. TIMING ALL OF THESE WAVES IS A NIGHTMARE...SO
FORECAST PACKAGE RELIED HEAVILY ON CONTINUITY...12 UTC GFS/NAM...09
UTC SREF MEAN...00 UTC ECMWF BLENDED TOGETHER WITH RELEVANT MOS
PRECIPITATION GUIDANCE.

CONCERNING TEMPERATURES...FRONTAL PASSAGE WILL CAUSE AN ABRUPT END
TO THE HOT TEMPERATURES IN NORTH DAKOTA...ALTHOUGH NEAR AVERAGE
TEMPERATURES SHOULD REMAIN UNTIL THE STRONGER FRONT PASSES ON
SATURDAY AFTERNOON/EVENING. THEREAFTER...IT APPEARS THAT
TEMPERATURES WILL REMAIN BELOW AVERAGE WELL INTO THE LONG TERM.

LONG TERM...MONDAY THROUGH THURSDAY
THE MODELS ALL AGREE IN OVERALL TREND ON THE BROAD SCALE BRINGING
AN UPPER LEVEL TROUGH INTO THE PLAINS. LOOKS LIKE MONDAY THROUGH
THURSDAY WILL HAVE A SLIGHT CHANCE OF TSTMS AND SHOWERS AND ANOTHER
ROUND OF COOLER WEATHER.

AVIATION...MAIN WEATHER FACTOR TONIGHT WILL BE THE DEVELOPMENT OF
THUNDERSTORMS MAINLY ALONG AND WEST OF A NEARLY STATIONARY FRONT
THAT EXTENDED FROM BOWMAN TO ROLLA AT 19Z. IF THUNDERSTORMS
DEVELOP...THE POTENTIAL IS FOR STRONG WINDS AND HAIL SIMILAR TO
LAST NIGHT.

FIRE WEATHER...ANOTHER DAY OF HOT TEMPERATURES IS ONGOING FOR
AREAS SOUTH OF THE FRONT STRETCHING FROM NORTHEASTERN INTO
SOUTHWESTERN NORTH DAKOTA. MINIMUM RELATIVE HUMIDITIES ARE
EXPECTED TO REMAIN IN THE 20S AND 30S PERCENT TODAY...SO ANY
LIGHTNING STRIKING THE GROUND AWAY FROM PRECIPITATION MAY SPARK A
FIRE OR TWO. THEREAFTER...MINIMUM RELATIVE HUMIDITIES SHOULD
REMAIN ABOVE THE MIDDLE 30S PERCENT DUE TO COOLER TEMPERATURES
BEHIND THE FRONT AND NEARBY PRECIPITATION. EXPECT WINDS OUT OF THE
NORTH/NORTHEAST NORTH OF THE FRONT AND SOUTH/SOUTHEAST ON THE
SOUTH SIDE.

&&

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