AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
345 PM CDT THU JUN 16 2011

.DISCUSSION...
NO EASY CALL ON TONIGHTS CHANCES FOR THUNDERSTORMS WITH THE STRONG
MCS IN EASTERN KANSAS POTENTIALLY ALTERING FLOW A BIT. A LOOK ACROSS
THE WESTERN HIGH PLAINS SHOWS SOME FAIRLY DRY AIR AT THE SURFACE
FROM SW KS SOUTHWARD WITH DEW POINTS 50 DEGREES OR DRIER. THERE DOES
APPEAR TO BE A WEDGE OF HIGHER DEW POINT AIR FROM SOUTHWEST NEBRASKA
INTO CENTRAL KS THAT COULD WORK NORTHWARD TONIGHT SO STILL SEEING A
GOOD THREAT FOR A WESTERN HIGH PLAINS MCS TO PROGRESS EAST INTO THE
CWA LATE TONIGHT. THE BEST CHANCES STILL APPEAR TO BE WEST OF
INTERSTATE 29 AND ESPECIALLY ALONG AND WEST OF THE JAMES RIVER
VALLEY. SEVERE THREAT STILL EXISTS WITH ELEVATED CAPE VALUES AROUND
1500 J/KG...ALBEIT VERY SKINNY CAPE...AND SOME MINOR AMOUNT OF
SHEAR. NOT EXPECTING A WIDESPREAD EVENT WITH THIS SET UP WITH THE
BEST CHANCES IN THE WESTERN CWA. WILL KEEP HIGHEST POPS CONFINED TO
THESE AREAS. FAIRLY EFFICIENT SET UP AS WELL WITH PWAT VALUES
CLIMBING TO AROUND 1.50 INCHES. OTHERWISE...WITH AN EAST TO
SOUTHEAST WIND REMAINING IN PLACE THROUGH THE NIGHT EXPECT MILD
LOWS...MAINLY IN THE 60S. /08

WITH GROUND SO SOGGY AND SOME FLOODING GOING ON IT WILL NOT TAKE TOO
MUCH TO BRING SOME FLASH FLOODING WITH EXPECTED THUNDERSTORMS FRIDAY
INTO FRIDAY EVENING. AM GOING WITH A FLASH FLOOD WATCH FOR THE
RECENT SOGGY AREAS WHICH GENERALLY IS ALONG AND NORTH OF INTERSTATE
90. WAS NOT SURE FOR A WHILE ON INCLUDING SOME OF OUR WESTERN AREAS
BUT THE POTENTIAL FOR HEAVY RAIN MAY BE A BIT BIGGER THERE...AT
LEAST NORTH OF THE INTERSTATE...THAN TO THE EAST AND THERE IS A
RIPER AREA SOUTH OF HURON.

TIMING IS A LITTLE TRICKY ON STORMS WITH SOME DECREASE POSSIBLE
FRIDAY MORNING FOLLOWED BY REDEVELOPMENT DURING THE DAY. HAVE GONE
WITH HIGH CHANCE TO LIKELY POPS INTO THE EVENING THOUGH FOR THE
WHOLE STRETCH OF TIME A POP WOULD SURELY BE HIGHER. WILL NOT
HIGHLIGHT SEVERE STORMS AT THIS TIME THOUGH HAVE NO QUARREL WITH THE
SLIGHT RISK. UPPER DYNAMICS WILL BE GOOD...BETTER THAN USUAL FOR
THIS TIME OF YEAR...WITH OTHER FACTORS SUCH AS THERMAL AND MOISTURE
GRADIENTS THERE BUT NOT THAT EXCITING.

ACTIVITY SHOULD DECREASE AND END FROM THE WEST FRIDAY NIGHT AS
IMPULSE MOVES THROUGH...THEN WE SHOULD HAVE A DRY AND MILD DAY
SATURDAY BEFORE SOME RIDGING AHEAD OF MAJOR WESTERN TROUGH BRINGS A
RETURN OF MOISTURE AND INSTABILITY AND A RETURN OF A THUNDERSTORM
THREAT BY SUNDAY. NEXT SYSTEM SEEMS TO HAVE BETTER POTENTIAL EVEN
THAN THIS ONE WITH THE DYNAMICS COMING IN EARLY NEXT WEEK BUT WILL
KEEP CHANCES TO HIGH CHANCE TO LOW LIKELY THREAT WITH THE TIMING
UNCERTAINTIES.

EVEN MORE UNCERTAINTY ABOUNDS WITH THE SPEED OF THIS NEXT DEEPER
WAVE MONDAY INTO TUESDAY. FOR NOW WILL DECREASE AND END STORMS BY
WEDNESDAY WITH JUST A RETURN TO SLIGHT CHANCE BY THURSDAY. THIS
SEEMS TO BE THE BEST GUIDANCE CONSENSUS FOR NOW BUT MODELS HAVE BEEN
CHANGING A LOT 5 PLUS DAYS AHEAD SO THIS IS ONLY OUR BEST SHOT. ONLY
GUARANTEE IN THIS PATTERN IS THAT TEMPERATURES WILL BE MILD TO WARN
DEPENDING MAINLY ON DAYTIME CLOUD COVER...BUT CERTAINLY NOT HOT.
/ WILLIAMS

&&

.AVIATION...
PRETTY MUCH VFR THROUGH LATER TONIGHT...THEN THUNDERSTORM CHANCES
WILL INCREASE FROM WEST TO EAST AFTER ABOUT 5Z. THE BEST CHANCE
SHOULD BE FROM ABOUT 5Z THROUGH 12Z FROM WEST TO EAST WITH SOME
HEAVY RAIN POSSIBLE. AS THE RAIN EXITS TO THE EAST AND NORTHEAST A
GOOD CHANCE FOR MVFR CONDITIONS WITH A CHANCE FOR IFR CONDITIONS FOR
AWHILE IN THE MORNING. ADDITIONAL CHANCES FOR THUNDERSTORMS WILL
EXIST THROUGH THE DAY ON FRIDAY.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST SOUTH DAKOTA...

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS...
SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP AND MOVE INTO
SOUTH CENTRAL SOUTH DAKOTA THIS EVENING...THEN CONTINUE NORTHEAST
ACROSS THE AREA OVERNIGHT. SOME OF THE STORMS NEAR THE MISSOURI
RIVER VALLEY COULD BECOME SEVERE THIS EVENING...WITH HAIL TO THE
SIZE OF HALF DOLLARS AND WIND GUSTS TO 60 MPH THE PRIMARY THREATS
SOUTHWEST OF A LINE FROM CHAMBERLAIN TO YANKTON SOUTH DAKOTA.

FLOODING...
RECORD HIGH RELEASES ARE OCCURRING FROM THE MISSOURI RIVER
RESERVOIRS AND WILL CONTINUE INTO MID SUMMER. HIGH WATER LEVELS
WILL CAUSE SIGNIFICANT IMPACTS BETWEEN CHAMBERLAIN AND SIOUX
CITY.

MANY PORTIONS OF THE JAMES RIVER VALLEY WILL SEE MINOR TO
MODERATE FLOODING THROUGH THE WEEKEND DUE TO RECENT RAINFALL. IN
ADDITION...HEAVY RAINS EARLIER THIS WEEK HAVE RESULTED IN MINOR
FLOODING ALONG PORTIONS OF THE ROCK RIVER AND LITTLE SIOUX RIVERS
IN NORTHWEST IOWA. LOWER PORTIONS OF THE BIG SIOUX RIVER ARE ALSO
EXPECTED TO RISE ABOVE FLOOD STAGE BY THIS WEEKEND.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

SCATTERED SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE
AREA...ESPECIALLY NORTH OF INTERSTATE 90...FRIDAY MORNING. THESE
STORMS ARE NOT EXPECTED TO BE SEVERE. HOWEVER...A COLD FRONT
