AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
804 PM CDT SAT MAY 22 2004

.DISCUSSION...

RADAR MOISIACS SHOWING NUMEROUS SUPERCELLS DEVELOPING ALONG WARM
FRONT WITCH IS SITTING WELL SOUTH OF CWA. LEADING EDGE OF RETURNS
WITH THE APPROACHING SHORTWAVE JUST BEGINNING TO ENTER THE SOUTHWEST
CWA. ONLY REAL CHANGES MADE TO GOING FORECAST IS DO ADJUST TIMING
AND POPS SLIGHTLY. STILL LOOKS LIKE POTENTIAL FOR HEAVY RAIN TONIGHT
AS WAVE ENTERS THE CWA...BUT AM CONCERNED THAT STRONG CONVECTION
ALONG THE WARM FRONT MAY ROB US OF OUR MOISTURE. THIS WILL HAVE TO
BE WATCHED AND CURRENT INDICATIONS STILL SUPPORT FLOOD WATCH AS FF
GUIDANCE VALUES INDICATE ITS NOT GOING TO TAKE MUCH RAIN TO GET SOME
FLOODING.

.PREV DISCUSSION...
LATEST WATER VAPOR LOOP SHOWS A POTENT UPPER LEVEL WAVE WITH A VERY
NICE DRY SLOT WORKING INTO SW NE. THE 18Z SURFACE ANALYSIS HAS A
SYNOPTIC FRONT FROM ABOUT KOGA TO KOFK TO KALO. A DEVELOPING WARM
AND MUCH MORE MOIST FRONT WAS LOCATED FROM ABOUT KHLC TO KCNK TO
KSTJ. LOOKS TO BE A MESO LOW FORMING NEAR KHLC WITH DRY/HOT AIR
WORKING INTO CENTRAL KS.

FOR LATE THIS AFTERNOON AND TONIGHT...MAY SEE TWO AREAS OF
CONVECTION DEVELOP. ONE WILL BE ACROSS NW CO AND WESTERN NE WHERE
STRONG LOW AND MID LEVEL FORCING WILL DEVELOP THIS AFTERNOON WITH
MODERATE INSTABILITY. MOST LIKELY MOVEMENT/DEVELOPMENT OF THIS
PRECIPITATION WILL TO THE NORTHEAST ALONG SYNOPTIC BOUNDARY. NEXT
AREA SHOULD BE OVER EASTERN NE AS DEVELOPING WARM FRONT CONTINUES TO
LIFT NORTH. MOVEMENT OF THIS ACTIVITY SHOULD ALSO BE
NORTHEAST...WITH RIGHT MOVING SUPERCELLS HEADING EASTNORTHEAST AND
LEFT MOVING SUPERCELLS MOVING ALMOST DUE NORTH. WITH THIS MOVEMENT
AND EXPECTED LOCATION OF WARM FRONT THIS AFTERNOON...WE SHOULD SEE
SOME SEVERE WEATHER FAR SOUTHERN CWA LATE AFTERNOON AND EVENING.
WILL CONTINUE FLOOD WATCH WITH SATURATED GROUND OVER CURRENT WATCH
AREA AND POTENTIAL FOR SIGNIFICANT RAINFALL AMOUNTS TONIGHT. WILL
ALSO BUMP POPS OVER SOUTHERN HALF OF CWA AS MISSING OUT ON RAINFALL
IN THAT AREA SEEMS DIFFICULT.

ANOTHER ROUND OF CONVECTION POSSIBLE AGAIN LATE SUNDAY INTO MONDAY
AS ANOTHER DECENT WAVE PASSES THROUGH. WILL HAVE SOME LATE NIGHT
POPS FOR ELEVATED RETURN FLOW ACTIVITY...THEN A DECENT CHANCE FOR
THE EASTERN CWA DURING THE AFTERNOON AND EVENING. CURRENTLY LOOKING
LIKE SOUTHEAST CWA WILL SEE BEST CHANCE FOR SEVERE WEATHER MONDAY
AFTERNOON/EVENING.

NEXT BETTER WAVE PROGGED BY BOTH THE ECMWF AND MRF TO COME OUT
FRIDAY INTO SATURDAY...AND WILL HAVE POPS FOR THIS.

NOT PLANNING ON CHANGING MUCH TEMPERATUREWISE FROM GOING FORECAST
OVER THE NEXT SEVERAL DAYS. THE MAIN CHANGE COME FOR SUNDAY...WHERE
CLOUDS AND COOLER AIR SHOULD KEEP MOST LOCATIONS FROM HEATING UP.
SHOOTING FOR NEAR 60 IN SW MN...TO THE MID 70S OVER THE SOUTHERN MO
VALLEY.
