AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 747 PM CDT WED JUL 18 2007 .DISCUSSION... RECENT MESOANALYSIS ACTUALLY LEAVES A LOT MORE QUESTIONS ON DEVELOPMENT TONIGHT. HAVE NOT SEEN ACTIVITY OUT WEST MAKE ANY AGRESSIVE EWRD PUSH...OUTSIDE A BRIEF ROGUE TS DEVELOPING BETWEEN KVTN AND KPHP. WOULD SEEM THAT ACTIVITY IS LARGELY UPSLOPE IN ORIGIN. OTHERWISE...THE ACC TRAIN CONTINUES OVR CWA WITHIN BROADLY FRONTOGENETIC ZONE. COLD POOL FROM EARLIER CONVECTION HAS NOW SHOVED FULLY S OF THE CWA...MAKING NR SFC AIR USELESS FOR ALL PRACTICAL PURPOSE. MOST UNSTABLE PARCEL IS MORE REASONABLE FOR LIFT DOWN TOWARD THE OUTFLOW/FRONTAL BNDRY IN NERN NEBRASKA... BASED 900-875HPA. DYNAMIC FORCING REALLY DOES NOT APPEAR TO GET ANY BETTER AFTER THE 03-06Z WINDOW...WITH WAVE MOVING THRU CNTRL SD ATTM. IF YOU SUBSCRIBE TO THE THEORY THAT THE ATMOSPHERE REACTS TO GRADIENTS...THEN IT WOULD APPEAR FROM THERMODYNAMIC ANALYSIS THAT THE MOST LKLY AREA FOR ADDITIONAL POTENTIALLY SIGNIFICANT DEVELOPMENT WOULD BE NEAR AND SOUTH OF THE MISSOURI RIVER...BUT REMAINING ELEVATED WITHIN OUR CWA. WOULD HAVE TO SEE THAT START UP SOON...OR THE WINDOW WL START TO SHIFT SWRD FOR DEVELOPMENT. WL BE MAKING SOME CHANGES TO FCST PACKAGE IN THE NEXT HOUR OR SO...TO REFLECT THESE THOUGHTS. && .PREV DISCUSSION... FIRST ROUND OF CONVECTION IS DEPARTING THE CWFA...WITH SOME SCATTERED REDEVELOPMENT ELSEWHERE IN THE ERN HALF. SFC BOUNDARY CONTS TO EXIST IN THE FAR SE PTN OF THE FA...ROUGHLY FM KSLB TO KSUX. CONCERNED ABOUT MORE CONVECTIVE DEVELOPMENT IN OUR SE CORNER IN THE NEAR TERM...POSSIBLY BEING SEVERE WITH HVY RAIN NEAR THE SFC BOUNDARY WHERE THE CAP HAS SUFFICIENTLY WEAKENED...EXCELLENT DEEP LYR SHEAR EXISTS...AND RAIN COOLED AIR HAS NOT REACHED. BUT OTHERWISE...ANOTHER CONCERN IS THE NEW CONVECTION THAT HAS DEVELOPED IN THE WRN PLAINS. THIS IS ASSOCIATED WITH THE LAST PIECE OF ENERGY WHICH HAS MOVED OUT OF WY AND MT...AND CURRENTLY IN THE WRN DKTS. DID SOME LAST MINUTE ADJUSTMENT TO THE WX/POP GRIDS TO ACCOUNT FOR POSSIBLE REDEVELOPMENT IN OUR ERN HALF...AND BOOSTED POPS IN OUR WRN HALF FOR LATE EVENING...KEEPING SOME HIGH POPS GOING IN MUCH OF OUR E SHORTLY AFTER MIDNIGHT...AGAIN LOOKING AT THE WRN PLAINS ACTIVITY. IT IS SORT OF A RACE...AS INSTABILITY IS HIGH. BUT THRU TIME TONIGHT...THE LOW LEVEL FLOW BECOMES INCREASINGLY MORE STABLE AS IT GETS DEEPER OUT OF THE NORTH. NOT EXPECTING MUCH FOR SVR ACTIVITY ANYWHERE AFTER AROUND 1 AM OR SO DUE TO THE WIND SHIFT. OTHERWISE...PLEASANT HIGH PRES TAKES OVER ON THU AND FRI. LOWERED TEMPS A TAD GIVEN THE NEW LOW LEVEL TEMPS OFF OF THE NAM AND GFS. ALTHOUGH THU WL BE GREATLY MIXED. RETURN FLOW BEGINS IN EARNEST ON SATURDAY PROVIDING SOME WARMER TEMPS. IN THE EXTENDED...LARGE BLOCKING HIGH STILL LOOKS TO BE IN PLACE. SO KEPT THE EXTENDED HUMID...DRY FOR WX AND WARM TO HOT. MJF && .AVIATION... MAIN ACTIVITY WL BE A THREAT FOR TS THIS EVENING AND OVERNIGHT. BE ALERT FOR POSSIBLE MVFR/IFR FOG AND STRATUS WHICH COULD DEVELOP LATE TONIGHT AND THUR MORNING DUE TO RAIN COOLED AIR. AT THIS POINT...HAVE MINIMIZED THAT POSSIBILITY IN THE TAFS DUE TO THE N TO NE SFC FLOW. BUT SOMETHING TO KEEP AN EYE ON. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE. NE...NONE. && CHAPMAN
