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 Jun 24, 3:32 AM CDT, 18 hours 1 minute earlier.

Area forecast discussion, Jun 24, 3:32 AM CDT, 18 hours 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
332 AM CDT TUE JUN 24 2008

.SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT
FORECAST CONCERNS/HIGHLIGHTS IN THE SHORT TERM WILL CONTINUE TO BE
CONVECTIVE CHANCES TODAY THROUGH THURSDAY NIGHT. BIGGEST CONCERN
WILL BE THE TODAY/TONIGHT PERIOD...AND THEN THE THURSDAY/THURSDAY
NIGHT PERIOD WHERE SEVERE WEATHER CHANCES INCREASE SUBSTANTIALLY.
WILL UTILIZE A GENERAL MODEL BLEND...AS ALL MODELS IN DECENT
AGREEMENT WITH TIMING AND PLACEMENT OF MAIN FEATURES.

CURRENTLY...A MID/UPPER LEVEL SHORT WAVE TROUGH HAS PUSHED EAST OF
THE REGION THIS EARLY MORNING...ALONG WITH ITS ASSOCIATED WEAK
SURFACE TROUGH. THESE FEATURES WERE RESPONSIBLE FOR SOME SEVERE
WEATHER THE OTHER EVENING ACROSS MY EASTERN COUNTIES...WITH THE
REMNANTS OF THIS CONVECTION FADING AWAY OVER SOUTH CENTRAL ND. OUR
NEXT SYSTEM/UPPER LEVEL WAVE IS ALREADY MOVING INTO WESTERN
MONTANA...RESULTING IN A DEVELOPING LEE SIDE SURFACE TROUGH
STRETCHED ACROSS THE NORTHERN HIGH PLAINS OF MT AND WY.

AHEAD OF THE SURFACE TROUGH TODAY WE WILL SEE SOUTH-SOUTHEASTERLY
WINDS INCREASING...RESULTING IN WAA AND MOISTURE ADVECTION INTO THE
NORTHERN PLAINS. WITH SFC DEWPOINTS CLIMBING INTO THE LOWER 60S AND
DAYTIME HIGHS CLIMBING UP INTO THE 80S...ATMOSPHERIC INSTABILITY
WILL RAPIDLY INCREASE THROUGHOUT THE DAYTIME HOURS. THIS SETS THE
STAGE FOR THUNDERSTORMS DEVELOPING AS THE LEE SIDE TROUGH ADVECTS
INTO WESTERN ND EARLY THIS AFTERNOON...AND AS THE UPPER LEVEL S/WV
TROUGH SLIDES EAST INTO THE LOCAL REGION. EXPECTING A MUCH GREATER
COVERAGE OF STORMS THAN WHAT WE SAW YESTERDAY...AS THIS FRONTAL
SYSTEM IS MUCH STRONGER ALONG WITH MORE FAVORABLE SHEAR PROFILES FOR
ORGANIZED CONVECTIVE ACTIVITY. PLENTY OF UPPER LEVEL SUPPORT FOR
LARGE SCALE ASCENT AS ALL MODELS PUT A BULLS-EYE OF DIVERGENCE OVER
CENTRAL ND BY 0Z. THINKING RIGHT NOW IS SOME SHOWERS SHOWING UP
LATER THIS MORNING OVER MY NORTHWEST CLOSER TO THE BEST ISENTROPIC
ASCENT...THEN MORE WIDESPREAD DEVELOPMENT WEST EARLY THIS AFTERNOON
AS LOW LEVEL CONVERGENCE AND MID/UPPER LEVEL DYNAMICS START TO
UTILIZE THE INCREASING CAPE. THE TROUGH AXIS/FRONTAL BOUNDARY WILL
THEN BE THE FOCUS FOR ONGOING CONVECTION THROUGH THE AFTERNOON AND
EVENING HOURS AS IT PROGRESSES EAST ACROSS THE FORECAST AREA. STRONG
TO SEVERE STORMS ARE LIKELY...WITH SPC PUTTING MUCH OF THE CWA IN
THE 30 PERCENT PROBABILITY FOR SEVERE HAIL AND DAMAGING WINDS. ISOLD
TORNADIC ACTIVITY ALSO POSSIBLE WITH THE SIG TOR PARAMETER MAXIMIZED
OVER SOUTH CENTRAL ND AND SPC PAINTING A 5 PERCENT PROB HERE WHERE
THE SFC WARM FRONT WILL BE LOCATED AND MOISTURE ADVECTION/POOLING
MAY BE MAXIMIZED.

MOST IF NOT ALL CONVECTION WILL HAVE PUSHED EAST BY AROUND MIDNIGHT
TONIGHT. WEAK CAA AND DRY CANADIAN AIR WILL MOVE IN BEHIND THIS
SYSTEM FOR WEDNESDAY UNDER A WEAK SURFACE HIGH PRESSURE. THE
ATMOSPHERE BECOMES UNSTABLE AGAIN HOWEVER DURING THE
AFTERNOON...PLUS EMBEDDED SHORT WAVE IMPULSES IN OUR WESTERLY FLOW
ALOFT ADVECT ACROSS THE REGION. THUS WILL CONTINUE OUR SLIGHT CHANCE
FOR THUNDER THROUGH WED NIGHT.

ANOTHER ROUND OF ORGANIZED STRONG TO SEVERE STORMS IS IN THE OFFING
FOR THURSDAY/THURSDAY NIGHT. LOOKS LIKE ALMOST AN IDENTICAL PATTERN
TO WHAT WE WILL SEE TODAY AND TONIGHT WITH ANOTHER FRONTAL BOUNDARY
AND UPPER LEVEL TROUGH MOVING THROUGH THE REGION. MINIMAL CHANGES
WERE NEEDED HERE...BUT DID INTRODUCE THE CHANCE FOR SEVERE
WEATHER.

.LONG TERM...FRIDAY THROUGH TUESDAY...
LINGERING SHOWERS AND THUNDERSHOWERS WILL PERSIST BEHIND THE SURFACE
TROUGH FRIDAY AS THE UPPER LEVEL COLD POOL COMES ACROSS THE STATE.
THE GFS40 TQ INDEX IS OVER 16 THROUGH THE EVENING HOURS. THIS
POINTS TOWARD COLD POOL CONVECTION.

THE REMAINDER OF THE EXTENDED PERIOD BRINGS A LARGE RIDGE OVER THE
WESTERN HALF OF THE NATION. WEAK IMPULSES MOVING SOUTHEAST DOWN THE
FRONT OF THE RIDGE MAY BRING SOME NOCTURNAL THUNDERSTORMS TO THE
AREA.

&&

.AVIATION...
MORE CONVECTION IS ON TAP FOR TUESDAY. I USED THE WRF 4KM MODEL FOR
LOCATION AND TIMING OF THE THUNDERSTORMS...SOME OF WHICH WILL BE
SEVERE. THE STRONGEST AND MOST ORGANIZED ACTIVITY WILL FORM IN A
LINE IN WESTERN NORTH DAKOTA AROUND 22Z AND THEN PROGRESS EAST TO
JMS BY 04Z WEDNESDAY.

&&

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