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 13, 2:57 PM CDT, 2 hours 11 minutes earlier.
Area forecast discussion, Jun 13, 2:57 PM CDT, 2 hours 11 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 257 PM CDT WED JUN 13 2012 .SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT... MAIN FORECAST PROBLEM IS THUNDERSTORM CHANCES TONIGHT. CURRENTLY...SURFACE LOW PRESSURE IS SITUATED OVER SOUTHEAST MONTANA WITH SOUTHERLY FLOW ACROSS WESTERN AND CENTRAL NORTH DAKOTA. SHORTWAVE LIFTING FROM NORTHERN MONTANA IN TO SOUTHERN SASKATCHEWAN IN PRODUCING A BAND OF SHOWERS THAT IS LIFTING ACROSS NORTHWEST NORTH DAKOTA. MOISTURE CONTINUES TO INCREASE OVER THE REGION WITH DEWPOINTS CURRENTLY IN THE MID 50S. MODELS INDICATE SCATTERED CONVECTION DEVELOPING ALONG THE EASTERN MONTANA COLD FRONT AS IT PUSHES INTO WESTERN NORTH DAKOTA. THE ONGOING CONVECTION IN THE NORTHWEST MAY ACTUALLY INHIBIT DESTABILIZATION...BUT WEST CENTRAL AND SOUTHWEST NORTH DAKOTA WILL SEE MORE SUN THIS AFTERNOON WHICH SHOULD HELP LOWER CONVECTIVE INHIBITION. CONVECTION WILL HAVE A SLIGHT TO MODERATELY UNSTABLE ATMOSPHERE TO WORK WITH INITIALLY WITH DECENT 0-6KM SHEAR. IN ADDITION...INCREASING LOW LEVEL MOISTURE IS NOT UNDERDONE BY FORECAST MODELS. AS CONVECTION TRACKS INTO CENTRAL NORTH DAKOTA SHEAR AND CAPE REMAIN BUT THE CAP STRENGTHENS AS YOU MOVE EAST FROM BISMARCK TO JAMESTOWN. HIGH RESOLUTION MODELS SEEM TO HIT ON THIS WITH THIS INITIAL CONVECTION HAVING A HARD TIME HOLDING TOGETHER AS IT MOVES INTO CENTRAL NORTH DAKOTA. A STRONG SHORTWAVE MOVING THROUGH WESTERN MONTANA THIS AFTERNOON WILL BE THE TRIGGER FOR EITHER ADDITIONAL THUNDERSTORM DEVELOPMENT THIS EVENING OR A STRENGTHENING OF CONVECTION THAT DEVELOPS THIS AFTERNOON ALONG THE EASTERN MT COLD FRONT. THE LATEST HRRR INDICATES CONVECTION DEVELOPING OVER THE NORTHERN HIGH PLAINS AND MOVING INTO THE WESTERN DAKOTAS BY MID EVENING AND TRACKING ACROSS THE LOCAL AREA LATE THIS EVENING AND OVERNIGHT. EML ADVECTING INTO THE REGION WILL MAINTAIN STEEP LAPSE RATES OVER THE FORECAST AREA TONIGHT. THIS CONVECTION MAY INITIALLY FORM AS DISCRETE SUPERCELLS BUT THEN DEVELOP INTO A LINEAR CONVECTIVE SYSTEM AS IT TRAVERSES THE AREA TONIGHT. ALTHOUGH A TORNADIC SUPERCELL CANNOT BE RULED OUT LATE THIS AFTERNOON OR THIS EVENING...THE MAIN THREAT OVERNIGHT WOULD BE LARGE HAIL AND DAMAGING WINDS. WITH PWATS INCREASING WELL ABOVE NORMAL...HEAVY RAIN CAN ALSO BE EXPECTED...ESPECIALLY FROM FROM THE FAR SOUTH CENTRAL INTO THE JAMES RIVER VALLEY. THIS AREA HAS NOT SEEN SIGNIFICANT RAINFALL LATELY AND THE PROGRESSIVE NATURE OF THE SYSTEM...WILL NOT ISSUE ANY HYDRO HEADLINES. PRECIPITATION MAY BE LINGERING IN THE FAR EAST ON THURSDAY MORNING. OTHERWISE THE MAJORITY OF THE DAY WILL BE DRY ACROSS THE SOUTHERN TWO THIRDS OF THE CWA. THE FAR NORTH WILL SEE A CHANCE OF SHOWERS AS THE UPPER LOW TRACKS ACROSS SOUTHERN CANADA. THE SHORT LIVED DRY SPELL SHOULD CONTINUE THROUGH THURSDAY NIGHT WITH UPPER LEVEL RIDGING OVER THE LOCAL AREA AHEAD OF THE NEXT SYSTEM. .LONG TERM...FRIDAY THROUGH NEXT WEDNESDAY... POTENT UPPER LEVEL WAVE/MID LEVEL CLOSED LOW WILL LIFT ACROSS THE ROCKIES AND THROUGH THE NORTHERN PLAINS FRIDAY-SATURDAY BRINGING LIKELY SHOWERS AND THUNDERSTORMS TO MOST LOCATIONS. UNCERTAIN IF WE WILL SEE WIDESPREAD SEVERE WEATHER THOUGH WITH DAYTIME HEATING ON FRIDAY LIMITED ALONG WITH MARGINAL CAPE. SCALED BACK CONSIDERABLY ON POPS SATURDAY AFTERNOON WITH DRY AIR PUNCHING INTO THE REGION FROM SOUTHWEST TO CENTRAL. LEFT CHANCES IN EAST FOR LINGERING SHOWERS/THUNDER...AND CHANCES ACROSS THE NORTH NEAR THE TRACK OF THE MID LEVEL LOW. DRY CONDITIONS REGION WIDE SATURDAY NIGHT WITH A WEAK RIDGE PUSHING ACROSS THE NORTHERN PLAINS. AFTERWARDS (SUN-WED)...OUR WEATHER PATTERN RETURNS TO VERY ACTIVE AS THE UPPER LEVEL JET BECOMES ORIENTATED OVER THE NORTHERN CONUS AND STEERS SEVERAL MID LEVEL DISTURBANCES FROM ACROSS THE ROCKIES INTO THE NORTHERN PLAINS. SHOULD SEE A GOOD CHANCE FOR PRECIPITATION EACH PERIOD. TEMPERATURES WILL AVERAGE NEAR NORMAL THROUGH THIS WEEKEND...TRENDING TO NEAR TO SLIGHTLY BELOW NORMAL MON-WED. && .AVIATION... AN AREA OF SURFACE LOW PRESSURE ACCOMPANIED BY AN UPPER LEVEL SHORTWAVE WILL COMBINE WITH INCREASINGLY UNSTABLE CONDITIONS TO BRING THUNDERSTORMS TO WESTERN INTO CENTRAL NORTH DAKOTA THIS AFTERNOON AND EVENING. MENTIONED VCTS GROUPS FOR ALL BUT KJMS. HEAVIER THUNDERSTORMS ARE POSSIBLE LATER THIS EVENING AND OVERNIGHT BEFORE 10Z MAINLY FOR KDIK...KBIS...AND KJMS. WHILE VFR CONDITIONS SHOULD PREVAIL FOR THE MAJORITY OF THE PERIOD...MVFR-IFR CONDITIONS CAN BE EXPECTED WITH ANY THUNDERSTORMS WHICH PASS OVER TERMINALS. && .BIS WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...TWH LONG TERM/AVIATION...NH
