AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 234 PM CDT SUN SEP 3 2006 .DISCUSSION... UPPER LEVEL LOW PIVOTING SLOWLY SOUTHEAST THIS AFTERNOON. MAIN UPPER LEVEL FORCING PUSHING INTO NORTHWEST IOWA...WHICH HAS SPARKED SOME THUNDERSTORMS FROM FAR SOUTHEAST SD INTO NORTHWEST IOWA. HAD A REPORT EARLIER OF A FUNNEL WETS OF CANTON...AND THIS ENVIRONMENT DEFINITELY SUPPORTS FUNNELS WITH STRONG ENHANCED STRETCHING POTENTIAL UNDER THE UPPER LOW AND NEAR ANY OF THE WEAK CONVERGENT BOUNDARIES AT THE SURFACE. INSTABILITY MARGINAL SO NOT EXPECTING WIDESPREAD SEVERE...MAINLY A FEW FUNNELS AND SOME QUARTER OR SMALLER HAIL. MOST OF THE THUNDERSTORM ACTIVITY WILL MOVE EAST OF THE AREA BY 00Z...BUT ADDITIONAL WRAP AROUND SHOWERS LIKELY INTO THE NIGHT AND POSSIBLY THROUGH MONDAY MORNING. AFTER THIS...PRETTY QUIET WEATHER MONDAY NIGHT INTO WEDNESDAY. DID NOT MAKE ANY DRASTIC CHANGES TO TEMPERATURES AS MIXING TO AROUND 850-800MB SEEMS REASONABLE AND LOWS BELOW GUIDANCE ALSO LOOK ON TRACK WITH RIDGE OF HIGH PRESSURE MOVING THROUGH. IN THE LATTER PERIODS(THU-SUN)...NORTHWEST FLOW PREVAILS WITH A COUPLE OF WAVES OF INTEREST. THURSDAY LOOKS LIKE A WEAKER WAVE DROPS SOUTHEAST ACROSS THE REGION...BRINGING ENHANCED WARMING AHEAD OF THE INCOMING FRONT. WILL BUMP TEMPS ABOVE GUIDANCE ON THURSDAY. DISAGREEMENT THEN SETS UP FOR FRIDAY THROUGH SUNDAY AS THE NEW 12Z GFS MORE IN LINE WITH THE 00Z GFS IN DRIVING FRONT SOUTH OF THE AREA ON THURSDAY NIGHT. THE ONLY DIFFERENCE IS THAT THE 12Z GFS BURIES THE FRONT IN NORTHERN OK. THIS SEEMS A LITTLE DRASTIC AS JET STREAK NOT EXTREMELY STRONG AND LOCATED FARTHER NORTH. THE 06Z GFS AND DGEX WANT TO TIE UP FRONT NEAR THE CWA AND THIS SEEMS A BIT TOO FAR NORTH. SO...WILL AIM FOR FRONT GOING SOUTH OF AREA...JUST NOT QUITE AS FAR AS 12Z GFS. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE. NE...NONE. && 08
