AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
939 PM CDT MON AUG 23 2004

.DISCUSSION...
STILL PRETTY QUIET ACROSS THE CWA THIS EVENING.  CELLS ON RADAR
STILL TRYING TO BACKBUILD INTO FAR NORTHEAST CWA...SO KEPT A SLIGHT
CHANCE GOING THERE...BUT OTHERWISE UPDATED EARLIER TO REMOVE EVENING
POPS FROM EASTERN COUNTIES.

ATTENTION THEN TURNS TO CHANCE FOR ADDITIONAL TSRA LATER TONIGHT.
TWO AREAS OF ONGOING ACTIVITY TO WATCH...ONE IN WESTERN NEBRASKA AND
ANOTHER DEVELOPING IN NORTHEAST KANSAS.  WEAK WAVE ASSOCIATED WITH
NEBRASKA STORMS SLIDES MAINLY SOUTH OF THE AREA OVERNIGHT...BUT 00Z
MODELS CONTINUE TO SHOW SOME WEAK LIFT WITH WARM ADVECTION LIFTING
NORTHEAST THROUGH FAR WESTERN PART OF THE CWA BY LATE TONIGHT.
PROBLEM IN THIS AREA IS PRETTY DRY LOWER LEVELS...SO ACTIVITY WILL
BE QUITE ELEVATED.  GOING SLIGHT CHANCE LOOKS LIKE BEST WAY TO GO.

AT THIS TIME...THINK ACTIVITY IN WESTERN NEBRASKA IS ALSO BEST
CHANCE FOR SOUTHERN AREAS TO SEE CONVECTION LATER TONIGHT...ALTHOUGH
NOT SURE IT WILL MAKE IT QUITE THAT FAR EAST BY DAYBREAK.  AS FOR
TSRA DEVELOPING IN KS...THIS LOOKS LIKE IT WILL STAY TIED CLOSELY TO
850 MB BOUNDARY...WHICH ALTHOUGH WEAK...REMAINS OVER FAR SOUTHERN
NEBRASKA AND NORTHERN MISSOURI.  WILL UPDATE TO DROP POPS OVER FAR
SOUTHERN CWA TO JUST SLIGHT CHANCE.  UPDATED GRIDS AND ZFP WILL BE
OUT SOON.
