The episode as NWS ABR wrote it up.
After a dry winter and spring, below normal rainfall for June brought severe drought conditions to the area. Much of the rainfall for June was below 50 percent of normal with much of the area receiving 20 to 40 percent of the normal rainfall. Some locations were at 10 to 15 percent of normal rainfall. Central and north central South Dakota were the hardest hit with the drought conditions. As a result of the severe dryness, alot of grazing land and stock ponds dried up and ranchers had to either buy additional feed for their animals, transport them to healthier pastureland for grazing, or sell their herds prematurely. CRP land was opened up to ranchers for haying and livestock grazing. Feed supplies and hay supplies were running short and water had to be hauled to alot of cattle. Crops suffered with much having to be cut up for hay or replanted. The crops that did make it have a low harvest potential. Water levels on lakes and rivers were also way down. Burn bans and voluntary or mandatory water restrictions were implemented across much of the area. All counties were declared drought disasters.

AREA FORECAST DISCUSSION FOR CENTRAL/N-EAST SD AND W-CENTRAL MN NATIONAL WEATHER SERVICE ABERDEEN SD 345 PM CDT FRI MAY 31 2002 MAIN FORECAST CONCERN WILL CONTINUE TO BE PROSPECTS FOR CONVECTION SATURDAY NIGHT INTO SUNDAY...AND ALSO TEMPERATURES SATURDAY AFTERNOON. MODELS IN FAIR AGREEMENT THROUGH 48 HOURS ALTHOUGH DIFFER SOMEWHAT IN EVOLUTION OF MID LEVEL SHORT WAVE NORTHWEST OF CWA SATURDAY NIGHT INTO SUNDAY. HOWEVER...EVOLUTION OF LARGER SCALE PACIFIC WAVE INTO EARLY NEXT WEEK IS HANDLED IN SIMILAR FASHION BY THESE MODELS. MAIN OUTLIER MODEL CONTINUES TO BE SLOWER AND CLOSED ECMWF SOLUTION. LITTLE CONCERNS FOR THIS EVENING WITH AVN AND ETA BOTH IN GENERAL AGREEMENT IN TAKING WEAK MID LEVEL WAVE NORTH OF CWA ACROSS NORTHEAST NORTH DAKOTA AND SOUTHEAST MANITOBA. SURFACE PRESSURE ANALYSIS SHOWS REFLECTION OF MID LEVEL WAVE WITH SLP TROUGH ACROSS NORTH DAKOTA. SOME CONVECTION ASSOCIATED WITH THIS SYSTEM NOTED IN PAST FEW HOURS ACROSS NORTH CENTRAL NORTH DAKOTA. DRY AIR ADVECTION SHOULD HINDER ANY PRECIPITATION CHANCES ACROSS NORTHERN CWA...SO WILL KEEP TONIGHT DRY ACROSS ENTIRE CWA. ONLY CONCERN FOR TONIGHT IS HOW FAST SURFACE DEW POINTS DROP ACROSS NORTHWEST CWA. MESOETA AND RUC SHOWING FAIRLY STRONG SURFACE DEW POINT GRADIENT APPROACHING WESTERN CWA. WILL GO FOR LOWEST OVERNIGHT TEMPERATURES IN THIS AREA IN THE LOWER 50S. FOR TOMORROW...UPPER PV ANOMALY ACROSS SOUTHWEST US EJECTS NORTHEASTWARD DOWNSTREAM OF LARGER SCALE UPPER TROUGH AXIS IN THE PACIFIC. BY TOMORROW AFTERNOON...BEGIN TO SEE MID LEVEL SIGNATURE OF UPPER ANOMALY ACROSS MONTANA/WYOMING WITH 700 HPA TROUGH DEVELOPING. GOOD ISENTROPIC LIFT ON 310K SURFACE NOTED BY LATE EVENING ACROSS MOST OF CWA. FAIRLY GOOD MAGNITUDE TO LOW LEVEL JET ALSO...WHICH WILL ENHANCE LOW LEVEL CONVERGENCE. ALSO SOME UPPER LEVEL DIVERGENCE NOTED IN ASSOCIATION WITH BROAD RIGHT ENTRANCE REGION OF UPPER JET. RETURN OF LOW LEVEL MOISTURE COMBINED WITH THE ABOVE FACTORS SHOULD ALLOW FOR GOOD CHANCE OF FAIRLY WIDESPREAD CONVECTION LATE SATURDAY NIGHT. BY SUNDAY STRONGEST LOW AND MID LEVEL FRONTOGENESIS AXIS MOVES NORTH OF CWA. ETA AND AVN HAVE BOTH TRENDED A LITTLE FARTHER NORTH WITH POSITIONING OF SLP MINIMUM AND FEEL THAT MOST WIDESPREAD PRECIPITATION WILL OCCUR NORTH OF CWA ON SUNDAY AND SUNDAY EVENING. HOWEVER...SECONDARY UPPER SPEED MAX AND WEAK UPPER DIVERGENCE DOWNSTREAM OF LARGER SCALE TROUGH AXIS RESULTS IN AN INVERTED SLP TROUGH AXIS ACROSS CWA IN BOTH ETA AND AVN SOLUTION. WITH LINGERING LOW LEVEL MOISTURE WILL KEEP CONVECTIVE CHANCES GOING THROUGH EARLY SUNDAY AFTERNOON. WILL KEEP MONDAY DRY AS CYCLOGENESIS WITH MAIN PACIFIC SHORT WAVE SHOULD OCCUR ACROSS CENTRAL PLAINS...KEEPING MAIN LOW LEVEL FRONTOGENESIS AND ISENTROPIC LIFT SOUTH OF CWA. NDM .EXTENDED DISCUSSION... GENERALLY KEPT ON A COURSE SIMILAR TO THE AVN. OTHER MODELS EXCEPTING ECMWF ARE LEANING TOWARD A LITTLE MORE PROGRESSION OF POSITIVELY TILTED ROCKIES TROF. HOWEVER THAT SAID THE AVN BOTH 00Z AND 12Z RUN MIGHT STILL BE A TAD FAST. POSITIVE TILT NATURE OF UPPER TROF SUGGESTS THAT MAIN SYNOPTIC BOUNDARY WILL REMAIN WELL SOUTH OF CWA. WILL THEREFORE KEEP TUESDAY THROUGH THURSDAY TIME PERIOD DRY. NOT REALLY CONFIDENT ABOUT DETAILS FOR FRIDAY BUT AT THIS TIME WILL LEAN TOWARD CHANCE OF THUNDERSTORMS FRIDAY AS NEXT UPPER TROF IS PROGGED ACROSS THE ROCKIES AND INTO THE PLAINS. MOSTLY BASED TEMPS OFF AVN 8H TEMPS AND MEX GUIDANCE. TDK .ABR...NONE.
