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

.DISCUSSION...
NOT TOO MANY CHANGES TO FORECAST THIS EVENING. WARM SECTOR TSRA
ACTIVITY HAS DIMINISHED WITH LOSS OF INSOLATION.  FOCUS NOW IS ON
BOUNDARIES IN THE AREA...DRY LINE/PRE FRONTAL TROUGH JUST WEST OF
THE CWA...AND WARM FRONT ACTIVITY ALONG FAR NORTHEAST BORDER.  NOT
MUCH MOVEMENT TO EITHER AREA OF STORMS...ALTHOUGH STARTING TO SEE
SOME ADDITIONAL DEVELOPMENT INTO FAR SOUTHWEST COUNTIES OF OUR CWA
AS OF 0230Z.  HAVE ADJUSTED POPS A LITTLE TO COVER ACTIVITY IN THE
NORTHEAST CWA BETTER...OTHERWISE PREVIOUS FORECAST OF TSRA CHANCE IN
CENTRAL SD SPREADING EAST OVERNIGHT LOOKS OK.  JH

&&

.PREV DISCUSSION...
PULSE THUNDERSTORMS CONTINUE TO REDEVELOP ACROSS THE REGION ON TAIL
END OF UPPER VORT LOBE MOVING THROUGH WESTERN MN. CONVECTION ALSO
DEVELOPING NORTHWARD FROM EASTERN NEBRASKA...WHICH WILL LIKELY TRACK
INTO NW IA BY LATE AFTERNOON AND EARLY EVENING. SHEAR PRETTY WEAK
AND INSTABILITY MARGINAL...SO ONLY PULSE HAILERS ARE EXPECTED.
ANOTHER AREA OF CONVECTION SHOULD DEVELOP OVER THE WESTERN HIGH
PLAINS OF THE DAKOTAS AS A STRONG WAVE ROTATES THROUGH EASTERN MT.
MOST OF THIS ACTIVITY WILL TRACK EAST AND NORTHEAST...BUT SOME
DEVELOPMENT COULD OCCUR AS FAR SOUTH AS OUR CWA...SO WILL CONTINUE
CHANCE POPS TONIGHT...JUST SLOW DOWN THE PROGRESSION A LITTLE. FRONT
SHOULD WORK INTO THE CWA ON TUESDAY AFTERNOON...AND WITH BETTER
SHEAR AND DECENT MOISTURE...SHOULD SEE A BETTER CHANCE FOR SEVERE
STORMS..ESPECIALLY OVER THE EASTERN HALF OF THE CWA.

QUITE A BIT OF DISAGREEMENT BETWEEN THE ETA AND GFS FOR WEDNESDAY AS
GFS TRIES TO HOLD ON TO SOME DAYTIME CONVECTION WHILE THE ETA IS DRY
AND HEATS US OUT A LITTLE MORE. WILL JUST GO CONSENSUS HERE AS MANY
THINGS COULD CHANGE DEPENDING UPON CONVECTION.

THURSDAY INTO THURSDAY NIGHT COULD PROVE TO BE DRY FOR MOST
LOCATIONS AS MAIN UPPER WAVE BEGINS TO DIG INTO THE SOUTHERN ROCKIES
AND BETTER MOISTURE ADVECTION AND MID LEVEL FORCING WELL WEST OF THE
AREA. ALSO THINKING THAT WITH RIGHT REAR QUAD OF UPPER JET MOVING
THROUGH THE WESTERN HIGH PLAINS AND A STRONG MID LEVEL FRONT...COULD
END UP WITH MOSTLY POST-FRONTAL ACTIVITY THURSDAY NIGHT. THAT WOULD
KEEP ALL BUT THE WESTERN THIRD OF THE CWA DRY. SO WILL ONLY PLACE
POPS OVER THE WEST THURSDAY NIGHT. BY FRIDAY...MAIN WAVE BEGINS TO
ROTATE NORTHEAST AND FRONT WORKS ACROSS CWA. IF THE SLOWING TREND
CONTINUES...FRIDAY COULD PROVE TO BE A PRETTY BUSY DAY WITH GOOD
SHEAR AND A STRONG UPPER LEVEL JET.

IN THE LATTER PERIODS...MAIN WAVE MOVES THROUGH LATE FRIDAY...BUT
ZONAL FLOW CONTINUES THROUGH THE WEEKEND INTO EARLY NEXT WEEK. WHILE
THE FORECAST WILL BE DRY ON SUNDAY AND MONDAY...NOT OUT OF THE
QUESTION TO SNEAK SOMETHING IN. OTHERWISE...BACK TO WHAT LOOKS LIKE
AT OR BELOW NORMAL TEMPERATURES SUNDAY AND MONDAY...SO WILL GO
SLIGHTLY BELOW GUIDANCE TO COMPENSATE FOR COOLER...POSSIBLY CLOUDIER
CONDITIONS.
