NWS Sioux Falls, SD wrote its last area forecast discussion before the first event at Jun 4, 9:59 AM CST, 4 hours 31 minutes earlier.
AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 1059AM CDT WED JUN 4 2008 .DISCUSSION... VERY ACTIVE 36 HOURS COMING UP AS A POTENT UPPER LEVEL WAVE DIVES INTO THE FOUR CORNERS REGION TODAY. FOR TODAY...PRECIPITATION SHOULD CLEAR OUT OF MOST AREAS...BUT WITH WEAK UPPER LEVEL SUPPORT AND A MOIST PROFILE...CANNOT RULE OUT ADDITIONAL SHOWERS AND ISOLATED THUNDERSTORMS THROUGHOUT THE DAY. IN FACT...SOME OF THIS UPPER LEVEL SUPPORT MOVING ONTO THE WESTERN HIGH PLAINS AND COULD SEE SOME OF THIS PRECIPITATION MOVE INTO THE WESTERN CWA THIS AFTERNOON. WILL TAKE OUT THREAT OF TORNADOES/LAND SPOUTS FOR THIS AFTERNOON AND EVENING WITH THE LACK OF A DECENT BOUNDARY AND LACK OF HEATING...ESPECIALLY NOW THAT THE CLOUD COVER IN THE WEST IS EXPANDING PRETTY RAPIDLY. OTHERWISE...HEADING INTO TONIGHT...PRETTY GOOD CHANCE THAT A FLOOD WATCH WILL NEED TO BE ISSUED FOR MOST OF SOUTHEAST SOUTH DAKOTA AS MODELS CONTINUE TO CONVERGE ON A SOLUTION THAT BRINGS HEAVY RAIN INTO CENTRAL/SOUTHEAST SOUTH DAKOTA TONIGHT INTO THURSDAY MORNING...WITH ADDITIONAL DEVELOPMENT LIKELY ON THURSDAY AFTERNOON AND EVENING. SEVERE THREAT TONIGHT PRETTY MUCH JUST HAIL AND MAINLY LATE. BETTER CHANCES FOR SEVERE SHOULD BE SOUTH OF THE CWA. 08 && AVIATION... SHOULD REMAIN PRETTY MUCH LOW END MVFR TO OCCASIONAL IFR IN FOG AND THUNDERSTORMS FOR THE NEXT 24 TO 36 HOURS. && .PREV DISCUSSION... ADVECTION SHOWERS WITH EMBEDDED THUNDER SPREADING EWRD EARLY THIS MORNING. LOOKS LIKE MUCH OF THE CWA SHOULD BE ABLE TO SQUEEZE OUT MEASURABLE PRECIP. SHOULD DRY OUT FOR A TIME LATER THIS MORNING INTO THE EARLY AFTERNOON AS BEST MID LEVEL FORCING SLIDES EAST OF THE AREA...HOWEVER CONVOLUTED MOIST WRLY FLOW MAKES IT HARD TO COMPLETELY DISCOUNT SHOWERS ANYWHERE DURING THE REMAINDER OF THE DAY. NOT ANTICIPATING MUCH IN THE WAY OF SUNSHINE TODAY AS SFC HEATING WOULD MOSTLY BE SELF DESTRUCTIVE PROVIDED THE ABUNDANCE OF SFC MOISTURE...WITH THE EXCEPTION POSSIBLY IN THE WEST. SEVERE THUNDERSTORM THREAT NON EXISTENT THROUGH THE EARLY AFTERNOON...BUT MAY HAVE TO WATCH WRN AREAS LATER THIS AFTERNOON AND EARLY EVENING. MOISTURE AND TEMPERATURE ADVECTION IN THE LOWEST LEVELS AND SOME OF DRYING IN THE 700 TO 500 MB LAYER SHOULD DESTABILIZE THE ATMOSPHERE ENOUGH BY LATE AFTERNOON FOR THUNDERSTORM DEVELOPMENT...ESPECIALLY IN PLACES WHICH DO SEE A BIT OF SUNSHINE. SHOULD TIMING BE RIGHT WITH S/WV PASSAGE...ENHANCEMENT OF CONVECTION CAN BE EXPECTED. NAM AND GFS DIFFER ON THE EXTENT OF CAPE WITH THE GFS YIELDING MORE ROBUST MU CAPE VALUES THIS AFTERNOON...ALTHOUGH ML CAPES ARE SOMEWHAT SIMILAR IN THE 800 TO 1400 J/KG RANGE BY 00Z THIS EVENING IN THE JAMES VALLEY WEST. DEEP LAYER DIRECTION SHEAR DOES SUPPORT THE POTENTIAL FOR SUPERCELL THUNDERSTORMS IN THESE AREA LATE TODAY INTO EARLY EVENING...HOWEVER BUFKIT SOUNDINGS INDICATED TALL SKINNY CAPE...WHICH DOES NOT SUPPORT VIGOROUS UPDRAFTS. SO...MAINLY THINKING MARGINAL SEVERE STORMS POSSIBLE WITH THE POTENTIAL FOR HAIL IN THE LOW END SEVERE RANGE. ONE OTHER THING TO WATCH WILL BE THE POTENTIAL FOR LANDSPOUTS WITH THESE STORMS. PROGGED 2 KM VGP VALUES IN THE .1 TO .4 RANGE AND LAPSE RATES AROUND 7 DEG/KM. SHOULD THERE BE ENOUGH SURFACE HEATING...WHICH REMAINS A QUESTION AT THIS TIME...THEN A FEW LANDSPOUTS ARE CERTAINLY A POSSIBILITY. BETTER CHANCES FOR SEVERE THUNDERSTORM WILL BE LATER TONIGHT AND THEN AGAIN LATE THU AFTERNOON INTO THU EVENING. STRONG ELEVATED WARM FRONT WILL MOVE NORTH ACROSS THE CWA AFTER MIDNIGHT TONIGHT. THUNDERSTORMS ARE ANTICIPATED TO DEVELOP ALONG THIS FRONT WITH SOME STORMS LIKELY BECOMING SEVERE. MAIN SEVERE THREAT WITH THESE ELEVATED STORMS WILL HAIL TO THE SIZE OF GOLF BALLS...AND POSSIBLY LARGER. THESE STORM SHOULD MOVE FROM THE SRN CWA AROUND MIDNIGHT...TO THE NRN EXTEND OF THE CWA TOWARDS SUNRISE. THEN GENERALLY SHOULD SEE A BREAK IN THE THUNDERSTORM ACTIVITY LATER IN THE MORNING AND INTO MID AFTERNOON. SET UP FOR LATE THU AFTERNOON/EVENING IS A POTENTIALLY VOLATILE ONE. SEVERE THREAT WILL LARGELY DEPEND ON PLACEMENT OF UPPER TROUGH AND SFC WARM FRONT. MODELS HAVING DIFFERENT IDEAS ON PLACEMENT AND TIMING BUT LIKELY THERE WILL BE HIGH THREAT OF SEVERE WX ALONG AND EAST OF I29 AND POSSIBLY AS FAR WEST AS THE WRN CWA BORDER. VERY LARGE HAIL...DAMAGING WIND GUSTS...AND STRONG TORNADOES WILL BE POSSIBLE. THE MAIN TORNADO THREAT WILL BE ALONG THE SFC WARM FRONT...WHICH AT THIS TIME IS EXPECTED TO BE DRAPED ACROSS SE SD AND SW MN. WILL ALSO HAVE TO MONITOR THE FLOOD POTENTIAL WITH THUNDERSTORMS TONIGHT AND AGAIN TOMORROW. THINGS DRY OUT ON FRIDAY AND STRONG COLD FRONT PUSHES EAST OF THE AREA. MODELS HAVE SHIFTED UPPER LOW FARTHER NORTH...SO LOWER THE CHANCES FOR POP FRI MORNING. RESIDUAL MOISTURE AND COOLER TEMPERATURES ALOFT...COULD SEE SOME SHOWERS/ISOLATED THUNDERSTORMS LATE IN THE DAY FRI. OTHERWISE OVERALL WET WX PATTERN TO CONTINUE INTO THE FORESEEABLE FUTURE. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE. NE...NONE. && LIEBL/RYRHOLM

MINOR TO MODERATE FLOODING IS EXPECTED ALONG PORTIONS OF THE VERMILLION RIVER THE NEXT FEW DAY. RAINS FROM THUNDERSTORMS ARE EXPECTED OVER THE NEXT FEW DAYS...WHICH COULD BE CAUSE FOR CONTINUED OR ADDITIONAL FLOODING. HEAVY RAIN WILL MOVE INTO SOUTHERN SOUTH DAKOTA TONIGHT AND CONTINUE INTO TUESDAY MORNING. RAINFALL AMOUNTS OF 1 TO 3 INCHES WILL BE POSSIBLE...ESPECIALLY ALONG AND WEST OF THE JAMES RIVER VALLEY. THIS COULD CREATE SOME LOCALIZED FLASH FLOODING ISSUES AS WELL AS INCREASE THE THREAT OF ADDITIONAL FLOODING ON CREEKS...STREAMS AND RIVERS. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY HEAVY RAIN AND SEVERE THUNDERSTORMS WILL AGAIN BE POSSIBLE THURSDAY AFTERNOON AND NIGHT. THE BEST CHANCE FOR SEVERE THUNDERSTORMS SHOULD BE SOUTH AND EAST OF A BROOKINGS TO YANKTON LINE WITH GOLF BALL SIZED HAIL...WIND GUSTS TO 70 MPH AND STRONG TORNADOES ALL THREATS. HEAVY RAIN WILL ALSO BE A THREAT TO THE WEST OF THIS LINE WITH AN ADDITIONAL ONE TO TWO INCHES OF RAIN LIKELY ACROSS MUCH OF THE AREA THROUGH LATE THURSDAY NIGHT. .SPOTTER INFORMATION STATEMENT...
