AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
355 AM CDT TUE JUN 18 2002

ONCE AGAIN...UNSETTLED FCST THRU MUCH OF THE WEEK WITH PERSISTENT SW
FLOW ALOFT. IN THE SHORT TERM...NUMEROUS BNDRYS EVIDENT ON THE VIS
SAT PICTURE. ONE IS IN SOUTHEAST NEB...ANOTHER CIRCULATION EVIDENT
WITH THE MID LVL LOW AND A SMALL BNDRY UNDERNEATH IT IN S CNTRL
SD...AND A THIRD IN SW MN WITH THE DEPARTING LINE OF WK CONVECTION.
MID LVL ENERGY IS STRONG MOVG INTO THE AREA THRU MIDNIGHT...AND THE
QSTN REMAINS...CAN WE CLEAR OUT...HEAT UP ENUF TO BREAK THE CAP. VIS
SAT SHOWS CI THINNING IN THE SW CWA...AND THE SPEED SHEAR IS THE
GREATEST THERE WITH 50 KTS IN THE MID LVLS ENTERING INTO THIS AREA.
SO SOMETHING COULD GO IN THAT AREA UNDERNEATH THE CIRCULATION. THE
ERN HALF OF THE CWA SHOWS STRONGLY VEERED SNDGS...BUT WITH LESS
SPEED SHEAR. SO CONVECTION IS DEFINITELY A THREAT...ALMOST ANYWHERE
ATTM IN THE FSD FA...AT LEAST THRU MIDNIGHT. AFT MIDNIGHT...MDLS IN
GOOD AGREEMENT ON PUMPING UP A STRONG MID LVL THERMAL RIDGE...
SEEMINGLY CAPPING THINGS OFF AGAIN. HOWEVER IF CONVECTION DOES GO
BEFORE MIDNIGHT...WARM MID LVL TEMPS WL LIKELY NOT HINDER THE TS TOO
MUCH UNTIL MAYBE SUNRISE. SO THEREFORE...OPTED NOT TO WORD ZONES FOR
EVE TS...EXCEPT IN THE WEST. AS ADVERTISED...STRONG LOW LVL BNDRY
BEGINS TO MOVE INTO THE FSD CWA ON WED...WITH STRONGLY CONFLUENT MID
LVL FLOW OVER IT. WARM MID LVL TEMPS COOL DRAMATICALLY...AND AM
EXPECTING TS TO REFORM ALONG AND BEHIND THE BNDRY IN THE WEST AND
NORTH THRU THE DAY...ENTERING THE SRN HALF OF THE CWA AT WED NIGHT.
POTENTIAL FOR MCS EXISTS NEAR THIS BNDRY LATE WED NIGHT MOVG UP FM
WRN NEB...IN THE FAVORED RIGHT REAR ENTRANCE RGN OF STRONG JET IN
ND. LOW LVL JET STAYS RATHER STRONG...BOTH TNGT AND WED TO KEEP THE
GULF FEED GOING...SO BLV LIKELY POPS ARE WARRANTED IN THE SOUTH HALF
WED NIGHT.

ON THURSDAY...STILL CONCERNED ABOUT LINGERING TS OR SHRA IN THE SRN
PARTS OF THE CWA...JUST NORTH OF THE STALLED LOW LVL BNDRY. AND ON
THURSDAY NIGHT AND FRI MRNG...BOTH MDLS DEPICT A RIDGE RIDER MOVG UP
THE SW FLOW ALOFT FROM THE WRN PLAINS. ALSO ETA SHOWS THE LOW LVL
BNDRY...LIFTING SLIGHTLY NWD INTO THE FSD CWA THU NIGHT...LIFTING
SLIGHTLY MORE NWD ON FRIDAY. AVN WASHES THIS BNDRY OUT MORE WHEN IT
IS SOUTH OF THE CWA THU EVENING...WHICH DOESNT MAKE A LOT OF SENSE.
SO STILL CANNOT RULE OUT PCPN CHCS THU NIGHT AND FRI...BUT WITH
DRYING CONDITIONS IN NW IA ON FRIDAY... CLOSER TO THE HEART OF THE
UPR RIDGE. SPEAKING OF WHICH...UPR RIDGE BECOMES CENTERED OVER THE
ERN FSD CWA FRI NIGHT THRU SAT NIGHT...ESSENTIALLY CAPPING THINGS
WITH SUBSIDENCE. NEW AVN SHOWS A DECENT RIDGE RIDER MOVG UP FM THE
WRN PLAINS FRI NIGHT AND SAT MRNG...WITH NO AFFECT ON THE FA. RIDGE
DOES BREAK DOWN HOWEVER ON SUNDAY...WITH THE NEXT WAVE PROGGED
SUNDAY NIGHT AND MONDAY. NOT MUCH TO KEY ON TUE ATTM.
