AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
915 PM CDT FRI JUN 6 2008

.DISCUSSION...
WEAK ELEVATED BNDRY LIFTING N ALONG I90. SHOWS UP ON SAT AND RADAR.
NAM PICKS UP ON THIS FEATURE AND WL LIFT NO OF I90 DURING THE NITE.
CUD BE FOCUS FOR SOME ELEVATED CONVECTION LATER TONIGHT SO WL UP
POPS A LTL FM PREVIOUS FCST. NAME IS PRETY UNSTABL WITH H85 LI-S S
OF I90 BY 12Z APPROACHING -9. OF COURSE THIS IS ALSO IN AN AREA
WHERE WARMER MID LEVL TEMPS EXPECTED SO IT MAY BE CAPPED. STILL NOT
COMPLETELY SURE IT WL BE CAPPED SO WL ADD SLIGHT CHC TO THE S.

&&

.AVIATION...
VFR...BUT OCNLY MVFR CIG IF TRW CAN DEVELOP AFT 06Z.

&&

.PREVIOUS DISCUSSION...
WINDS SHOULD WIND DOWN THIS EVENING AND CLOUDS SHOULD DISSIPATE
...BUT STILL EXPECT WINDS AROUND 10 TO 15 MPH THROUGHOUT THE NIGHT
AT MOST LOCATIONS. THIS SHOULD AID IN KEEPING TEMPERATURES UP A BIT
DESPITE LOWER DEW POINTS. WILL AIM FOR MID 50S TO LOWER 60S ACROSS
THE AREA.

OTHERWISE...FALL LIKE PATTERN SETTING UP FOR TH WEEKEND AS A STRONG
UPPER LEVEL JET WORKS INTO NORTH DAKOTA TONIGHT AND TIGHTENS UP THE
MID LEVEL BOUNDARY ACROSS THE AREA. THINGS LOOK A LITTLE TOO DRY
BELOW ABOUT 700MB TO REALLY GET ANYTHING GOING...SO THE FOCUS FOR
ANYTHING WILL LIKELY BE AT THIS LEVEL. INSTABILITY PRETTY MINIMAL SO
WILL JUST GO SHOWERS FOR NOW AND MAINLY IN THE FAR NORTH.

WEAK COLD FRONT GRADUALLY SHIFTS EAST THROUGH FORECAST AREA ON
SATURDAY BUT WITH LIMITED MOISTURE INSTABILITY/PRECIPITATION SHOULD
BE FAIRLY LIMITED WITH MAINLY LIGHT SHOWERS IN THE MORNING HOURS.
WITH THE UPPER LEVEL FORCING HANGING BACK TO THE WEST...HAVE SIDED
WITH SLOWER FRONTAL TIMING OF NAM AS OPPOSED TO GFS. BOUNDARY
APPEARS TO GET HUNG UP ACROSS SOUTHEASTERN PORTION OF FORECAST AREA
TOMORROW.  SOUTHERLY FLOW SOUTH OF THE BOUNDARY WILL ALLOW MOISTURE
TO RETURN TO THE REGION...CREATING THE POTENTIAL FOR SCATTERED
THUNDERSTORMS SOUTH OF THE BOUNDARY ACROSS NORTHWEST IOWA TOMORROW
AFTERNOON. FAIRLY SIZABLE CAP IN PLACE SHOULD KEEP CONVECTION
CHANCES DOWN TILL LATE AFTERNOON OR INTO THE OVERNIGHT SATURDAY
NIGHT AS A SHORTWAVE APPROACHES FROM THE SOUTHWEST. WITH CLOUDS AND
PRECIP HANGING AROUND...TEMPERATURES ON SUNDAY SHOULD BE QUITE COOL
NEARLY 10 DEGREES BELOW NORMAL.

A SHORTWAVE WILL MOVE THROUGH UNDER ZONAL FLOW ON MONDAY CREATING
ADDITIONAL CHANCES OF OF PRECIPITATION ADDING TO WHAT HAS BEEN A WET
PATTERN AS OF LATE. A WARM FRONT IS EXPECTED TO LIFT NORTH INTO THE
REGION ON TUESDAY...BEFORE A STRONG COLD FRONT AND WRAPPED-UP UPPER
LEVEL WAVE MOVES THROUGH THE NORTHERN PLAINS ON WEDNESDAY NIGHT INTO
THURSDAY. THIS APPEARS TO BE THE BEST CHANCE OF ORGANIZED SEVERE
WEATHER OVER THE NEXT WEEK. ZONAL FLOW CONTINUES INTO THE WEEKEND
WITH WEAK WAVES MOVING THROUGH AS THE UPPER LEVEL JET REMAINS
POSITIONED OVER THE NORTHER TIER OF THE US.
