FORECAST DISCUSSION FOR EASTERN NORTH DAKOTA AND NORTHWEST MINNESOTA NATIONAL WEATHER SERVICE EASTERN ND/GRAND FORKS ND 315 PM CDT MON JUN 23 2003 MAIN FORECAST CHALLENGE WILL BE DEALING WITH ANY ADDITIONAL RAINFALL DUE TO THE PERSISTENT SOUTHWEST FLOW ALOFT. MODELS REMAIN IN DECENT AGREEMENT IN KEEPING LITTLE CHANGE IN THE SOUTHWEST FLOW THRU WED BEFORE WAVE FINALLY MOVES THRU ON THU. WILL CONTINUE TO LEAN TOWARD THE ETA FOR THE GRIDS. MAIN CONVECTIVE CLUSTER STILL JUST BRUSHING OUR EASTERN FRINGE COUNTIES. HAVE SEEN LARGE HAIL/STRONG WINDS AND FLASH FLOODING ASSOCIATED WITH THESE. THESE WILL CONTINUE PROGRESSING EASTWARD AND SHOULD CLEAR OUR FA SHORTLY. FAIRLY WEAK SFC FLOW MAKES PICKING OUT ANY BOUNDARIES DIFFICULT. HOWEVER THE STALLED SFC BOUNDARY AND LOW LEVEL QUASI/STATIONARY FRONT STILL LIE ACROSS THE FA. SFC DEW POINTS IN THE MID-UPPER 60S OVER ALMOST ENTIRE FA. SOME CLEARING HAS LED TO BETTER HEATING AND MSAS COMPUTED LIS WELL BELOW ZERO ALL ALONG THE STATIONARY BOUNDARY. JET INDUCED MID-UPPER LEVEL CLOUDS ACROSS THE WESTERN DAKOTAS ARE PRODUCING SOME ELEVATED THUNDERSTORMS/LIGHTNING STRIKES. FLOW WILL BRING THESE INTO OUR FA SO WILL KEEP A THUNDER CHANCE THRU MIDNIGHT ALL AREAS AND ONLY TAKE OUT KDVL REGION AFTER MIDNIGHT. BIG DISCREPENCY IN MODEL QPF BY 00Z-06Z TUE...WITH ETA BULLSEYE GOING TO SOUTHWEST MN AND AVN CENTERED IN WEST CENTRAL MN. THINK THE ETA DEPICTION MUCH MORE SENSIBLE WITH LOW LEVEL JET KICKING IN FURTHER SOUTH TONIGHT. EITHER WAY...WILL STICK WITH FLASH FLOOD HEADLINES DUE TO SATURATED SOILS TONIGHT. MAY ALSO ADD A PATCHY FOG MENTION LATE. WEAK EMBEDDED WAVES IN THE SOUTHWEST FLOW CONTINUE INTO TUE. MAIN SFC FEATURES DO SHIFT SOUTHEAST...WITH HIGH BRINGING MORE STABLE AIR INTO THE NORTHWEST FA. WILL KEEP A BROADBRUSHED CHANCE OF PCPN FOR THE ENTIRE AREA AND RESTRICT THUNDER TO THE SOUTH. SPC DAY 2 CONVECTIVE OUTLOOK KEEPS SLIGHT RISK AREA TO THE SOUTH OF THE FA SO WILL FINALLY GET SEVERE WORDING OUT OF THE GRIDS. SAME STORY CONTINUES TUE NIGHT SO WILL GO WITH PERSISTENCE. HARD TO BE IN A HURRY TO REMOVE PCPN CHANCE ON WED...BUT WILL GO WITH SHOWERS AS BEST INSTABILITY SHIFTS SOUTH. MODELS SHOW 500 MB TROUGH AXIS FINALLY MOVING EAST OF THE FA BY THU...BUT IT DOES BRING ANOTHER WEAK WAVE IN THE CYCLONIC FLOW AND A COLD POOL. SO WILL ADD A THUNDER CHANCE THU AFTERNOON. .EXTENDED...LONGWAVE TROUGH AXIS FORECAST OVER CENTRAL ND FRIDAY WILL SHIFT OVER THE GREAT LAKES ON SUNDAY AND MONDAY. OPERATIONAL 500 HPA GFS IS IN REASONABLE AGREEMENT WITH THE ENSEMBLE MEAN HOWEVER THE ENSEMBLE MEAN HAD HIGHER AMPLITUDE FOR SATURDAY AND LOWER HEIGHTS OVER THE GREAT LAKES FOR SUNDAY AND MONDAY. WILL GO COOLER FOR SATURDAY THROUGH MONDAY THAN CURRENTLY FORECAST. SOUTHWEST FLOW ALOFT WILL RETURN TO THE AREA BY NEXT MONDAY WITH A CHANCE OF PRECIPITATION. SHORT WAVE FORECAST TO MOVE THROUGH FRIDAY WITH PRECIPITATION MOST LIKELY IN THE NORTHEAST ZONES. .FGF...FLASH FLOOD WATCH ALONG AND SOUTH OF A LINE FROM KFAR-KPKD TONIGHT. GODON/HOPPES
