AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
340 PM CDT TUE JUN 14 2011

.DISCUSSION...
THUNDERSTORMS THE MAIN FOCUS FOR THIS AFTERNOON AND EVENING. RAIN
HAS BEEN PERSISTANT WITH THUNDERSTORMS AND RAINFALL RATES OF 1 TO
NEARLY 2 INCHES AN HOUR HAS CAUSED FLASH FLOODING OVER MUCH OF SW
MN. RADAR ESTIMATES OF 3 TO 4 INCHES HAVE BEEN VERIFIED BY GROUND
REPORTS. AREAS OF RAIN MAINLY OVER SW MN THIS AFTERNOON IS EXPECTED
TO LIFT NE THE REST OF THIS AFTERNOON AS THE MAIN THETAE ADVECTIVE
MOVES INTO CENTRAL AND EASTERN MINNESOTA. FLASH FLOOD THREAT WILL
SUBSIDE AS THUNDERSTORMS EXIT THE FORECAST AREA. OVERALL CHANCES FOR
THUNDERSTORMS WILL CONTINUE INTO THE EARLY MORNING HOURS. TROUGH OF
WARM AIR ALOFT WILL KEEP CHANCES GOING INTO THE EVENING EAST OF
INTERSTATE 29 WHILE SURFACE BASED CONVECTION IS POSSIBLE MAINLY WEST
OF THE JAMES VALLEY. POTENTIAL FOR SEVERE THUNDERSTORMS EAST OF
INTERSTATE 29 IS RAPIDLY DECREASING THIS AFTERNOON AS EFFECTIVE
SHEAR DROPS FROM 40-50 KTS AT 18Z TO 10-20 KTS BY 00Z. MAIN CHANCE
FOR SEVERE THUNDERSTORMS WILL BE ALONG THE WESTERN FRINGES OF THE
FORECAST AREA UNTIL EARLY THIS EVENING. MAINLY WILL HAVE WATCH THE
SURFACE TROUGH WHERE THERE IS DEEPER INSTABILITY AND LOCALIZED SHEAR
EXISTS. SPC MESOANALYIS INDICATING 2500 J/KG OF SURFACE BASED CAPE
NEAR CHAMBERLAIN AS OF 19Z. SURFACE CAPE RAPIDLY DECREASES INTO THE
JAMES VALLEY DUE TO COOL EASTERLY FLOW. SHOULD SEE CAPE VALUES DROP
OFF BY LATE THIS AFTERNOON AS TROUGH MIXES DRIER AIR IN FROM THE
WEST AND SURFACE HEATING WANES. OTHERWISE FOR TONIGHT...CHANCES FOR
PRECIPITATION DECREASING FROM WEST TO EAST WITH CLEARING BEHIND THE
TROUGH. SHOULD SEE WESTERLY FLOW AND CLEAR SKIES ACROSS THE FORECAST
AREA TOWARDS SUNRISE. /97

IT IS BORDERLINE ON WHETHER THERE COULD BE ANY LINGERING LIGHT
SHOWERS IN SOUTHWEST MN EARLY WEDNESDAY MORNING...WILL LEAVE A
SLIGHT CHANCE FOR THE FAR NORTHEASTERN EDGE JUST FOR THE EARLY
MORNING. OTHERWISE A WESTERLY FLOW OF DRY MILD AIR SHOULD BRING
CLEAR TO MOSTLY CLEAR SKIES. AN UNSTABLE AND SLIGHTLY MORE MOIST AIR
BRUSHING THE SAME NORTHEAST EDGE MAY GIVE WAY TO SPOTTY
THUNDERSTORMS THERE AND WILL GO WITH A SLIGHT CHANCE FOR THE
AFTERNOON. TEMPERATURES STILL ON TRACK FOR A MILD AND PLEASANT
DAY...POSSIBLY GETTING A BIT BREEZY AROUND MIDDAY BUT NOT REALLY
WINDY. WINDS WILL THEN DROP OFF TO GIVE A CLEAR AND PLEASANT EVENING.

MOISTURE AND INSTABILITY RETURN STARTS QUITE RAPIDLY FROM THE SOUTH
LATER WEDNESDAY NIGHT AND CONTINUES THURSDAY WITH THE RIDGING AHEAD
OF SIGNIFICANT WESTERN USA TROUGH. HAD A THOUGHT OF BRINGING A
MENTION TO THE FAR SOUTH LATE WEDNESDAY NIGHT BUT IT SHOULD TAKE A
LITTLE WHILE FOR THE MOISTURE TO GET DEEP ENOUGH EVEN FOR MID LEVEL
CONVECTION. WILL BRING IN THE SLIGHT CHANCE SLOWLY THURSDAY DURING
THE UNFAVORABLE DAYTIME PERIOD THEN KEEP MENTION OF THUNDERSTORM
CHANCE ALL OF AREA FOR THURSDAY NIGHT ON THROUGH THE REST OF THE
FORECAST PERIOD...OR THROUGH NEXT TUESDAY. REAL FINE TUNING
DIFFICULT AT THIS TIME SINCE WITH THE MAJOR TROUGH APPROACHING
SLOWLY FROM THE WEST...THERE SHOULD NOT BE ANY VERY LONG PERIOD
WITHOUT A THREAT. 12Z GFS AND EC RUNS HINT AT PUSHING THE THREAT
THROUGH A BIT FASTER NEAR THE END OF THE PERIOD BUT WILL NOT PULL
THE TRIGGER OM A DRY DAY 7 YET ESPECIALLY SINCE SHOWERS MAY LINGER
ON THE BACK SIDE OF THE UPPER LOW EVEN IF THESE MODELS ARE RIGHT.

TEMPERATURES WILL BE SOMEWHAT WARMER DURING THE FORECAST PERIOD THAN
THEY HAVE BEEN WITH MOST OF THE WARMING ON NIGHTTIME TEMPERATURES
GIVEN QUITE A BIT OF CLOUD COVER EXPECTED AND THE WARMEST AIR
STAYING SOUTH OF AREA. / WILLIAMS

&&

.AVIATION...
SHOWERS AND THUNDERSTORMS CONTINUE MAINLY OVER SOUTHWEST MINNESOTA
THIS AFTERNOON...MUCH OF THIS ACTIVITY SHOULD MOVE OUT OF THE AREA
BY EARLY THIS EVENING. MORE THUNDERSTORMS ARE POSSIBLE OVER CENTRAL
SOUTH DAKOTA LATE THIS AFTERNOON AND THEN COULD MOVE ACROSS EASTERN
SOUTH DAKOTA THIS EVENING. THUNDERSTORMS TO END OVERNIGHT AS TROUGH
AXIS MOVES EAST OF THE AREA. LOTS OF IFR ACROSS THE FORECAST AREA
THIS AFTERNOON WITH THUNDERSTORM ACTIVITY AND STRATUS. WILL BECOME
VFR AS DRY AIR MOVES IN BEHIND THE TROUGH. /97
