AREA FORECAST DISCUSSION FOR CENTRAL/N-EAST SD AND W-CENTRAL MN NATIONAL WEATHER SERVICE ABERDEEN SD 315 PM CDT MON JUN 24 2002 MAIN FORECAST CHALLENGE IS THE CONTINUING CHANCE FOR THUNDERSTORMS TONIGHT. CURRENT ANALYSIS SHOWS A FRONT SITUATED FROM NORTHEAST TO SOUTHWEST OVER THE SOUTHERN PART OF THE CWA. A FEW SHOWERS AND THUNDERSTORMS HAD DEVELOPED ALONG THE FRONT AS OF 19Z...MAINLY FROM BIG STONE COUNTY IN MN TO JONES COUNTY. THIS FRONT LOOKS TO CONTINUE TO BE THE FOCUS FOR THUNDERSTORM DEVELOPMENT THIS EVENING INTO TONIGHT...BEFORE IT FINALLY PUSHES SOUTH AS A COLD FRONT TUESDAY. WILL CARRY ABOUT A 50 POP FOR ALL BUT THE EXTREME NORTHWESTERN CWA TONIGHT. CAPES RUNNING RIGHT AROUND 2200 J/KG IN THE SOUTHERN AND EASTERN CWA...WITH LIS OF -4 OR GREATER. MAY SEE A FEW SEVERE STORMS DEVELOP ALONG THE FRONT WHERE THE INSTABILITY WILL BE THE STRONGEST. HIGH PRESSURE MOVES INTO THE REGION BEHIND THE FRONT ON TUESDAY...ALONG WITH AN UPPER LEVEL RIDGE BUILDING OVER THE WESTERN U.S. THIS WILL BE THE GENERAL PATTERN THEN FOR THE REMAINDER OF THE FORECAST PERIOD. EXPECT DRY CONDITIONS FROM TUESDAY RIGHT INTO THE EXTENDED. TEMPERATURES SHOULD REMAIN FAIRLY WARM WITH PLENTY OF SUNSHINE ASSOCIATED WITH THE HIGH PRESSURE...AND LOW LEVEL TEMPERATURES REMAINING IN THE UPPER TEENS TO LOWER 20S. .EXTENDED DISCUSSION... CONDITIONS REMAIN DRY ACROSS THE EXTENDED PERIODS AS HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE AREA. A WEAK TROUGH APPROACHES THE REGION ON SUNDAY...BUT THERE IS LITTLE MOISTURE AVAILABLE...SO WILL JUST SEE AN INCREASE IN CLOUD COVER INTO SUNDAY AND MONDAY. THERE IS A HINT FOR A CHANCE OF PRECIPITATION INTO THE BEGINNING OF NEXT WEEK...BUT WILL KEEP THE FORECAST DRY FOR NOW. .ABR...NONE PARKIN/MJA
