AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
332 PM CDT MON AUG 2 2004

.DISCUSSION...

FOR THIS AFTERNOON...BAND OF MID LEVEL CONVECTION DEVELOPING OVER
THE NORTHERN CWA. SOME THREAT OF HAIL FORM THESE STORMS...POSSIBLY A
LITTLE WIND. THIS CONVECTION SHOULD CONTINUE THROUGHOUT THE
AFTERNOON AND INTO THE EVENING...DEVELOPING SLOWLY SOUTH AS IT MOVES
EAST. THE OTHER THREAT AREA WILL BE OVER THE SOUTHWEST CWA NEAR A
SFC BASED BOUNDARY AND WEAK MESO LOW. THIS AREA AND POINTS NEAR THE
MISSOURI VALLEY REGION WILL SEE THE MAIN THREAT FOR TORNADIC
ACTIVITY IF THUNDERSTORMS DEVELOP. WILL ALSO HAVE HIGHEST POPS IN
THIS AREA AS SHEAR AND INSTABILITY SUGGEST POTENTIAL TO BECOME
ORGANIZED WHEN IT DEVELOPS. PWAT VALUES ALSO VERY HIGH...ABOVE 2
INCHES...SO SIGNIFICANT DOWNPOURS WILL BE POSSIBLE. STORM MOTION
SHOULD BE QUICK ENOUGH THAT TRAINING WILL NOT BE A MAJOR ISSUE...SO
WILL NOT BE ISSUING A FLOOD WARNING.

EXPECT A DECENT MCS TO DEVELOP FROM ACTIVITY DEVELOPING THIS
AFTERNOON...WHICH SHOULD PUSH THE JUICY AIR AND LOW LEVEL BOUNDARY
PRETTY FAR SOUTH. WILL STILL INCLUDE LOW POPS FOR TUESDAY AFTERNOON
AND EVENING AS BOTH THE GFS AND 18Z MESOETA TRY TO BRING ACTIVITY
BACK INTO MAINLY SOUTHERN CWA.

A WEAK WAVE WITH MID LEVEL FRONTOGENESIS SKIRTS ACROSS NORTHERN SD
ON WEDNESDAY...BUT WILL NOT INTRODUCE ANY POPS AT THIS TIME.
TEMPERATURES WILL FALL BACK TO BELOW NORMAL AS BOUNDARY SLIDES
SOUTH. SHOULD BE A LITTLE HUMID AGAIN ON TUESDAY...BUT COOLER AND
DRIER AIR SLIDES IN FOR WEDNESDAY AND THURSDAY.

IN THE LATTER PERIODS...FRIDAY AND SATURDAY SHOULD SEE A WARMING
TREND FROM THE COOLER AIR WORKING IN MID WEEK...AHEAD OF NEXT
BOUNDARY COMING SOMETIME LATE SATURDAY THROUGH SUNDAY. ECMWF/GFS AND
CANADIAN ALL SHOW THIS FEATURE...SO WILL AGREE WITH THIS AND LEAVE
POPS IN FOR SATURDAY NIGHT. FOR SUNDAY AND MONDAY...WILL GO A LITTLE
BELOW GUIDANCE AS CANADIAN AND ECMWF BOTH A LITTLE COOLER THAN THE
GFS. BOTH THE ECMWF AND CANADIAN HANDLED CURRENT INCOMING COLD FRONT
FOR TUESDAY BETTER THAN THE GFS LATE LAST WEEK.
