The local office's own words before the first event, 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 the first event at Jul 25, 1:55 PM CST, 7 hours 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 255 PM CDT WED JUL 25 2001 FORECAST CONTINUES TO BE ONE POP AFTER ANOTHER...SOMETHING I DO NOT LIKE TO DO...BUT GIVEN THE SITUATION...HAVE NO CHOICE. NGM FROM YESTERDAY DID A BETTER JOB BY HANGING BACK ON THE PRECIP FOR THIS MORNING. HOWEVER...WITH TONIGHTS ROUND OF PRECIP IT LOOKS TO TAKE IT OUT OF THE CWA TOO QUICKLY THURSDAY MORNING. ETA/AVN WERE IN CLOSER AGREEMENT. ACTUALLY THE FORECAST WILL BE A COMPILATION OF THE 3 MODELS. PROBLEM THROUGH PERIOD IS CHANCE OF THUNDERSTORMS IN WEST FLOW AS UPPER LOW IN WESTERN SASKATCHEWAN CONTINUES TO ROTATE WEAK WAVES THROUGH NORTH DAKOTA. SURFACE SUPPORT IS IN THE FORM OF A STALLED TROF ALONG THE MONTANA BORDER THAT WILL MEANDER EAST AND WEST INTO THURSDAY. THIS SHOULD ACT AS A FOCUS MECHANISM FOR STORM DEVELOPMENT. LIFTED INDICES REMAIN 0 TO -4 RANGE NEXT FEW DAYS WITH CAPES STEADILY RISING...FROM 500 TO 1600. FEELING IS INDIVIDUAL STORMS WILL FIRE WEST AND FORM INTO A LARGE COMPLEX OF WEAK STORMS/RAIN...AND MOVE SLOWLY EAST. WITH THAT...WILL KEEP CHANCES GOING CENTRAL AND EAST THURSDAY MORNING. ONE WAVE AFTER ANOTHER CONTINUES INTO FRIDAY NIGHT CONTINUING THE CHANCES FOR STORMS. A POTENTIAL REPERCUSSION COULD BE ON HIGH TEMPS...WITH CLOUDS/RAIN HOLDING THEM BACK INTO EARLY AFTERNOON. A BREAK COMES SATURDAY AS MID LEVEL RIDGING RIDGES IN...FOLLOWED BY A DEEPENING H5 LOW IN THE WEST WHICH REESTABLISHES SOUTHWEST FLOW INTO ND FOR SUNDAY-TUESDAY. THANKS TO KABR FOR COORDINATION ON POSSIBLE FLASH FLOOD WATCH. CONCERN IS LOW FLASH FLOOD GUIDANCE SOUTHWEST-SOUTH CENTRAL ND INTO NORTH CENTRAL SD. WILL OPT NOT TO ISSUE ONE NOW AS QPF IS HIGHLY UNCERTAIN. AND IF STORMS DO FORM INTO A LARGE AREA OF RAIN IT WOULD REDUCE THE RISK OF FFLOODING...SPREADING RAIN AMOUNTS OUT OVER TIME. WILL PASS ON TO EVENING SHIFT TO RE-EVALUATE. .BIS...NONE. GJP MARTIN
