AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 423 AM CDT WED JUN 4 2008 .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. && AVIATION...
