231 AM CDT WED JUL 29 1998

PCPN THREAT THE PRIMARY CONCERN THIS FCST.  EXTREMELY DIRTY FLOW PTRN
EXPECTED TO CONT ACRS FCST AREA THRU THE END OF THE WEEK...WITH FRONTAL
BOUNDARIES CONVERGING ON REGION.  NGM/AVN LOOK MUCH MORE LIKE ETA THIS
RUN...ALTHO PREFER ETAS DEPICTION OF 2 DISTICNT FRONTS VS NGM/AVN
WHICH BLEND THE TWO.  ONE FRONT FROM SE NEB ALNG MO/IA BRDR AT 07Z
FCST TO DRIFT INTO NRN MO AND STALL OUT.  SRN BDRY SOMEWHERE ALNG A
LINE FM NRN OK TO NR MO/ARK BRDR...AND THIS ONE FCST TO DRIFT SLOWLY
NWD.  ELEVATED TSRA ALL OVER SRN KS INTO SW MO ATTM...WITH ADDL
REDVLPMT OVR SC KS.  WILL BREAK OFF SRN ZONES FOR CAT WORDING AS EXPECT
THIS TO PERSIST FOR MUCH OF MORNING.  MAY BE A BREAK THERE FOR A TIME
THIS AFTN...BUT CHCS FOR REDEVLPMT AS WELL.  CONTEMPLATED A FLOOD WATCH
FOR FAR SRN COUNTIES...AND TOUCHED BASE WITH SGF/STL. BUT...LATEST LOOK
AT RADAR ESTIMATES SUGGEST AMTS WONT BE TOO BAD.  FOR NOW...WILL HOLD
OFF AND HOPE FOR THE BEST.  CENTRAL THIRD WILL NEED POPS TDY FOR PSBLTY
THAT THIS MORNING CNVCTN COULD DVLP NWD SOME...AND WITH BDRYS NRBY SOME
AFTN DVLPMT WORTH DECENT POPS.  WILL BOOST SOME.  FOR NRN THIRD...MDLS
/ESP ETA/ REALLY DRY OUT NE MO BEHIND FROPA.  AM TEMPTED TO BREAK OFF
FAR NE CORNER TO REMOVE POP TDY.  OTW...WILL MAINTAIN A LOW POP FOR
REMAINDER OF NRN THIRD WITH BDRY AND MOISTR IN PLACE.

TONITE...BETTER DYNAMICS IN PLACE WITH RIPPLE IN THE FLOW WORKING ACRS
AREA IN CONJUNCTION WITH RRQ OF UPR JET.  EXPECT MCS TO BLOW ACRS NEB
AND TREK SE TWD NW MO...AND ALSO COULD SEE DVLPMT RIGHT OVR FCST AREA
WITH H8/H7 BDRYS LYING NW-SE ACRS FCST AREA...SIMILAR TO CRNT ACTION AND
TREND OF PAST SEVERAL NIGHTS.  WILL MAINTAIN HIGH POPS TONITE AND EVEN
BOOST INTO THURS.

TEMPS TO BE PROBLEMATIC AS WELL WITH LOTS OF CLDS EXPECTED AND PDS OF
RAIN.  THINK THERE WILL BE JUST ENOUGH BREAK FM THE CLDS/PCPN TDY TO
ALLOW THE MERCURY TO REACH THE MID 80S MOST AREAS.  A BIT COOLER OVR
NE MO.  LOWS IN LATEST PKG APPEAR ON TARGET TONITE...BUT WILL LWR HIGHS
ON THURS A NOTCH DUE TO EXPCTD RAIN/CLDS.

LATEST RUN OF AVN SUPPORTS DRY TREND FOR WKND...SO NO CHGS THERE.

KS...NONE
MO...NONE
