AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
647 AM CDT SAT JUN 8 2013

.SHORT TERM...(THIS AFTERNOON THROUGH SUNDAY)
ISSUED AT 640 AM CDT SAT JUN 8 2013

MESSY WEEKEND AHEAD WITH THE POTENTIAL FOR HEAVY RAIN AND SOME
FLOODING. FIRST OFF...WITH VERY LITTLE INSTABILITY OR SHEAR TODAY
THE THREAT FOR SEVERE THUNDERSTORMS IS VERY LOW. MAYBE AN ISOLATED
HAILER OR TWO IN THE WESTERN CWA LATER THIS AFTERNOON BUT FOR NOW
JUST THINKING AN EFFICIENT RAINMAKING SYSTEM OVER THE NEXT 24 HOURS.
A BAND OF WARM ADVECTION ACCOMPANIED BY A WEAK LEAD UPPER LEVEL WAVE
WILL ALLOW SHOWERS AND THUNDERSTORMS TO CONTINUE TO PROGRESS
EASTWARD. THIS AREA WILL LIKELY REACH THE FAR EASTERN CWA BY LATE
MORNING WHILE THE WESTERN AREA MAY SEE A LULL FOR AWHILE. RAINFALL
AMOUNTS...WHILE NOT PROLIFIC COULD REACH CLOSE TO AN INCH IN SPOTS
THROUGH EARLY AFTERNOON WITH THE WARM ADVECTIVE BAND WITH PWAT
VALUES ABOUT 1.35 INCHES AND A FAIRLY DEEP BUT VERY SKINNY CAPE. BY
MID AFTERNOON STRONG UPPER LEVEL SUPPORT...NOTED AS A VERY STRONG
WAVE FOR THIS TIME OF YEAR ON THE 7Z WATER VAPOR IMAGE IN EASTERN
MONTANA...WILL MOVE INTO THE JAMES RIVER VALLEY AND IF TEMPERATURES
CAN WARM A LITTLE MORE THAN EXPECTED MAYBE AN ISOLATED SEVERE STORM
WOULD BE POSSIBLE...MAINLY BECAUSE OF THE STRENGTH OF THE UPPER
FORCING...BUT FOR NOW EXPECT THEM TO REMAIN BELOW SEVERE CRITERIA.
THIS SECONDARY AREA OF SHOWERS AND THUNDERSTORMS WILL BRING ANOTHER
ROUND OF DECENT RAINFALL POTENTIAL...LIKELY IN THE HALF AN INCH TO
INCH AND A HALF RANGE. WILL NOT ISSUE ANY FLOODING HEADLINES YET BUT
WITH FLASH FLOOD GUIDANCE AROUND 2 TO 2.5 INCHES IN MANY LOCATIONS
WILL NEED TO KEEP AN EYE ON THE RIVERS AND LOCAL CREEKS AND STREAMS
TONIGHT IF THE SECOND AREA OF HEAVY RAIN CAN SET UP IN THE SAME AREA
AS WHAT OCCURS THIS MORNING. BACKED OFF ON HIGHS FURTHER TODAY WITH
MORE CONFIDENCE IN CLODS AND PRECIPITATION BUT GENERALLY HIGH IN THE
60S...MAYBE NEAR 70 IN CENTRAL SOUTH DAKOTA AND SOUTHERN PARTS OF
NORTHWEST IOWA.

CONVECTION BEGINS SHIFTING EAST TONIGHT BUT MODELS SLOW TO TAKE
UPPER LEVEL SUPPORT EAST...SO WILL NEED TO KEEP SOME POPS IN FARTHER
WEST THAN PREVIOUS FORECAST. HEAVIER RAIN CONTINUES TO BE THE MAIN
THREAT AND MAINLY OVER NORTHWEST IOWA AT THIS TIME.

.LONG TERM...(SUNDAY NIGHT THROUGH FRIDAY)
ISSUED AT 640 AM CDT SAT JUN 8 2013

MONDAY INTO TUESDAY SHOULD BE FAIRLY QUIET TIME FRAME WITH
TEMPERATURES MODERATING BACK MUCH CLOSER TO NORMAL. HIGHS FROM 75 TO
85 WITH LOWS IN THE 50S TO LOWER 60S WILL MAKE IT FEEL A LITTLE MORE
LIKE SUMMER. POSSIBLY A BIT OPTIMISTIC WITH TEMPERATURES FOR MONDAY
AS GROUND WILL LIKELY BE VERY WET BUT STILL SEEMS PRETTY LIKELY.

DURING THE WEDNESDAY THROUGH FRIDAY TIME FRAME AN INTERESTING
PATTERN LOOKS TO SET UP. WHILE RIDGING ALOFT IS EXPECTED TO DEVELOP
AND SUSTAIN THROUGH THE PERIOD THE RIDGE IS NOT EXCEPTIONALLY
STRONG. WITH SUGGESTIONS THAT A LOW LEVEL BOUNDARY COULD BE IN PLACE
OVER CENTRAL NEBRASKA INTO WESTERN SOUTH DAKOTA A BIT OF AN MCS LIKE
PATTERN MAY EVOLVE WHERE THUNDERSTORMS DEVELOP OVER THE WESTERN HIGH
PLAINS DURING THE AFTERNOON AND EVENING THEN SPREAD EASTWARD INTO
THE AREA AS THE LOW LEVEL JET STRENGTHENS AND VEERS TO THE SOUTHWEST
AS INDIVIDUAL WAVES PASS. ENOUGH DIFFERENCES IN THE MODELS THAT
SELECTING A TIME FRAME IS NOT EASY BUT WILL LEAN TOWARDS WEDNESDAY
THEN AGAIN THURSDAY NIGHT INTO FRIDAY AS HOLDING THE MOST POTENTIAL
FOR HIGH IMPACT WEATHER. IF WE DO GET THE HEAVIER RAIN POSSIBLE
TODAY THEN ANY ADDITIONAL THREATS FOR HEAVY RAIN WILL START TO
CREATE SOME PROBLEMS THUS THIS WILL NEED TO BE CLOSELY WATCHED.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z SUNDAY MORNING)
ISSUED AT 641 AM CDT SAT JUN 8 2013

LOW CONFIDENCE FORECAST TODAY IN TERMS OF BOTH CEILING AND
CONVECTION TIMING. WARM AIR ADVEICTION BAND OF SHOWERS AND
THUNDERSTORMS MOVING THROUGH THE AREA THIS MORNING. CURRENT RADAR
AND SATELLITE TRENDS WOULD SUGGEST A BREAK TOWARDS MID
DAY...HOWEVER....SHORT TERM MODELS CONTINUE TO INDICATE SHOWERS
AND THUNDERSTORMS CONTINUING TO DEVELOP ACROSS THE AREA THROUGHOUT
THE DAY. WITH LACK OF LOW CEILINGS ACROSS THE REGION....HAVE
RAISED CEILING EVEN THOUGH SOUNDING PROFILES AND RH TIMES SECTIONS
INDICATE NEARLY SATURATED ENVIRONMENT THROUGH THE AFTERNOON INTO
THE OVERNIGHT.
