AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1053 AM CDT TUE JUN 14 2011

.DISCUSSION...
SHOWERS AND THUNDERSTORMS CONTINUE TO REDEVELOP AHEAD OF A WEAK
UPPER WAVE MOVING ACROSS SOUTHWEST MINNESOTA. RAINFALL RATES HAVE
PUSHED 2 INCHES PER HOUR WITH SOME OF THESE STORMS...WHICH HAS BEEN
CAUSE FOR WATER IN THE STREETS IN SOME COMMUNITIES. OVERALL THE
FLASH FLOOD THREAT IS LOW THE REST OF THE DAY...BUT A COUPLE OF
INCHES OF RAIN ARE CERTAINLY POSSIBLE IN A SHORT PERIOD OF TIME OVER
PORTIONS OF SOUTHWEST MINNESOTA THROUGH EARLY THIS AFTERNOON. MOST
OF THE REMAINDER OF THE FORECAST AREA SHOULD STAY DRY THROUGH MUCH
OF THE DAY WITH THUNDERSTORMS REDEVELOPING ACROSS CENTRAL SOUTH
DAKOTA...THEN MOVING EAST ACROSS THE FORECAST AREA THIS EVENING AND
OVERNIGHT. A GOOD PUSH OF WESTERN WINDS FOLLOWING THE PASSAGE OF A
TROUGH SHOULD ALLOW FOR SKIES TO CLEAR OUT. TEMPERATURES FORECAST IN
RELATIVELY GOOD SHAPE FOR TODAY...ALTHOUGH AREAS WHERE RAIN HAS
BEEN FALLING THIS MORNING MAY BE A FEW DEGREES TO WARM. WILL MAKE
MINOR MODIFICATIONS TO THE FORECAST SHORTLY.  /97

&&

.AVIATION...
SHOWERS AND THUNDERSTORMS CONTINUE MAINLY OVER SOUTHWEST MINNESOTA
THIS MORNING...MUCH OF THIS ACTIVITY SHOULD MOVE OUT OF THE AREA BY
EARLY THIS AFTERNOON. MORE THUNDERSTORMS ARE EXPECTED TO DEVELOP
OVER CENTRAL SOUTH DAKOTA AND THEN MOVE ACROSS EASTERN SOUTH
DAKOTA...SOUTHWEST MINNESOTA...AND NORTHWEST IOWA THIS EVENING AND
OVERNIGHT. VISIBILITY AND CEILINGS VARY GREATLY ACROSS THE FORECAST
AREA THIS MORNING. LOTS OF IFR ACROSS FAR SOUTHEAST SOUTH
DAKOTA...AND INTO NORTHWEST IOWA...SOUTHWEST MINNESOTA DUE TO LOW
STRATUS. THIS SHOULD HANG AROUND THROUGH THE DAY BUT LOW CLOUDS WILL
CLEAR OUT FROM WEST TO EAST TONIGHT. /97

&&

.PREV DISCUSSION...
WANING ELEVATED BOUNDARY CONTINUING TO PRODUCE A LINE OF SCATTERED
SHOWERS VERY EARLY THIS MORNING FROM NEAR BRIDGEWATER TO DELL RAPIDS
TO TRACY. MORE SIGNIFICANT SHOWERS/THUNDERSTORM COMPLEX TRACKING
ALONG THE SOUTH DAKOTA/NEBRASKA NEAR TYNDALL...AND PUSHING TO THE
EAST. QUESTION BECOMES WHERE THIS COMPLEX WILL END UP THIS
MORNING...WITH THE HRRR MODEL ONCE AGAIN HANDLING THE CONVECTION
POORLY. IF IT HOLDS TOGETHER...AT ITS CURRENT RATE OF SPEED IT WILL
TRACK ACROSS OUR NORTHWESTERN IOWA ZONES BETWEEN 12Z AND 14Z THIS
MORNING. WITH THE EXIT OF THIS FEATURE...THINK THERE WILL BE A
GENERAL BREAK IN ACTIVITY UNTIL LATE MORNING/EARLY AFTERNOON WHEN
REDEVELOPMENT WILL OCCUR IN OUR WEST WITH THE APPROACH OF A MORE
SIGNIFICANT UPPER LEVEL TROUGH. CURRENT OBS/SATELLITE INDICATING AN
AREA OF STRATUS OVER MUCH OF THE CENTRAL AND SOUTHEASTERN PORTIONS
OF THE COUNTY WARNING AREA...AND MODEL RH FIELDS INDICATING THAT THE
STRATUS WILL HOLD OVER MUCH OF THE CWA THROUGH MOST OF THE
DAY...THOUGH MAY BREAK IN THE WEST BY AFTERNOON. THIS WILL PLAY A
PART IN KEEPING THE POTENTIAL FOR SEVERE STORMS AT BAY. MARGINAL
CHANCE OF SEVERE STORMS WILL OCCUR OVER OUR SOUTH CENTRAL SOUTH
DAKOTA ZONES...WHERE MUCAPE VALUES PER BUFKIT SOUNDINGS ARE PROGGED
TO BE AROUND 2000 J/KG BY AFTERNOON...THOUGH EFFECTIVE SHEAR VALUES
ARE FAIRLY LOW...SO THINK THAT A SEVERE STORM WOULD BE ISOLATED IF
IT OCCURS AT ALL. EXPECT RAINFALL AMOUNTS TO REMAIN IN
CHECK...GENERALLY RUNNING FROM NEAR 3 TENTHS TO AROUND HALF AN INCH
FOR THE PERIOD OF TODAY/TONIGHT...WHICH WILL REMAIN BELOW FLASH
FLOOD GUIDANCE...EVEN IN AREAS THAT RECEIVED SO MUCH RAIN ON MONDAY.
IF RAINFALL AMOUNTS WOULD COME IN HIGHER THAN FORECASTED...WOULD
NEED TO WATCH FOR FLASH FLOODING THROUGH THE CENTRAL PORTIONS OF THE
JAMES RIVER VALLEY WHERE THE STATIONARY BAND SET UP YESTERDAY. WITH
THE CLOUDS AND AN EASTERLY LOW LEVEL FLOW...HIGHS WILL REMAIN BELOW
NORMAL WITH UPPER 60S TO NEAR 70 EAST TO LOWER/MID 70S WEST AND FAR
SOUTH.

SHOWERS AND THUNDERSTORMS WILL OVERSPREAD THE AREA FROM WEST TO EAST
TONIGHT...EXITING OUR EAST ON WEDNESDAY MORNING AS THE UPPER WAVE
PUSHES INTO THE UPPER MIDWEST. BEHIND THE EXITING
WAVE...NORTHWESTERLY WINDS WILL PICK UP ON WEDNESDAY AFTERNOON. WITH
CLEARING SKIES AND BETTER MIXING...HIGHS EXPECTED TO MAKE IT INTO
THE MID 70S NORTHEAST TO AROUND 80 THROUGH THE JAMES RIVER VALLEY
INTO THE MISSOURI RIVER CORRIDOR.

THURSDAY WILL BE MAINLY DRY AND WARMER AS UPPER LEVEL RIDING BUILDS
INTO THE REGION. DID THROW SOME SLIGHT POPS IN ALONG THE MISSOURI
RIVER CORRIDOR WITH INCREASING MOISTURE TRANSPORT/INSTABILITY ON A
DEVELOPING LOW LEVEL IN CONJUNCTION WITH A WEAK MIDLEVEL WAVE
TRACKING ACROSS THE REGION. HIGHS ON THURSDAY LOOKING TO BE IN THE
UPPER 70S TO LOWER 80S. A BETTER WAVE EMBEDDED IN THE UPPER LEVEL
RIDGE PUSHES INTO THE AREA ON FRIDAY...WITH SLIGHTLY BETTER CHANCES
FOR SHOWERS/THUNDERSTORMS.  /JM
