MCS WEST OF GID IS PROPAGATING SEWRD WITH TIME AS IT FEEDS INTO THE
MOISTURE RICH ATMOS IN PLACE.  850H LLJ AND THETA-E AXIS IN PLACE IS
AIDING THE SEWRD MOVEMENT OF THE MCS INTO NRN KS.  CURRENT MODEL
DATA SHOWS CORFIDI VECTORS AND 850-300MB THICKNESS VALUES TAKING
THIS MCS SE INTO CEN KS LATE TNGT OR EARLY THU MORNING TOWARDS ICT.
EXTROPOLATION BRINGS THIS MCS INTO THE RSL/SLN BY 06Z AND SOUTH INTO
HUT/ICT BY AROUND 09-10Z.  SO WILL SEND OUT AN UPDATE AND GO LIKELY
IN CEN SECTIONS OF KS AND RAISE POPS TO 40-50 IN SRN KS. BOWING

330 PM CDT WED JUN 11 2003

DATA AS OF THIS AFTERNOON DOES NOT SHOW MUCH OF A FOCUS FOR ANY TSTM
DVLPMENT FOR LATER THIS AFTN AND EVENING. BEST FOCUS APPEARS TO BE
OVER THE NRN/CNTRL HIGH PLAINS...WELL N OF OUR REGION. WK WV MOVING
THROUGH THE TX PNHNDL IS SHOWN IN THE WV/SAT IMAGERY...BUT IS ONLY
PRODUCING MID CLOUDS ATTM. FEATURE IS MOVING NWD CLOSER TO MY SRN
ZONES...AND WL WATCH FOR SOME DVLPMNT NEAR THE OK BORDER THIS
EVENING. OVERALL...ATMOS IS WEAKLY CAPPED AS OF THIS AFTN AND INSTAB
IS HIGH...BUT THERE IS NO TRIGGER. IF ANYTHING GOES, IT WL BE VERY
ISOLD.

ANOTHER WV KICKS OUT INTO THE SRN AND CNTRL PLAINS TONIGHT...WHICH
WL BE ACCOMPANIED BY A MODEST LLJ AND ISENT LIFT. ETA IS STRONGER
WITH THESE FEATURES...ESP THE ISENT LIFT. ALL MODELS SHOW THAT THESE
FEATURES WL CONTRIBUTE TO CONVECTIVE DVLPMT TNGT ACRS NEBR.
PROPAGATION VECTORS SUGGEST THAT LEFTOVER MCS COULD MOVE INTO THE
CWA VERY LATE TONIGHT THROUGH EARLY AFTN TOMORROW. THE ETA IS MOST
AGGRESSIVE WITH BRINGING TSRA IN...BUT THATS NO SURPRISE AS ITS
ISENT LIFT PROGS ARE MUCH STRONGER IN OUR AREA...AND FURTHER SOUTH
THAN THE OTHER MODELS. GOING FCST MENTIONS SLT CHC OF TSRA
TNGT...AND I WILL KEEP THE MENTION. UPPED POPS LATE TNGT INTO TMRW
MORNING TO AROUND 30 FOR NRN AND ERN SXNS IN CASE WEAKENING MCS
DECIDES TO CLIP AREA AS PER ETA.

OVERALL...NOT MUCH CHANGE TO THE GOING FCST FOR OTHER PERIODS. HAVE
BASICALLY KEPT THE LOW CHC POPS GOING THROUGH THE WEEKEND. UPR FLOW
IS WK AT BEST...AND SUBTLE UNRESOLVED FEATURES WL BE THE MAIN
CULPRITS FOR CONVECTIVE INITIATION OVER THE NEXT FEW DAYS. SUPPOSE
THE BEST CHC FOR SHRA/TSRA CUD BE LATE FRI/FRI NGHT/SAT...AS MID LVL
COOL POCKET STRENGTHENS OVERHEAD AS IT MOVES SEWD AND TRIES TO CLOSE
OFF. HAVE REFLECTED THIS THINKING IN POP FCST...WITH HIGHEST POPS
DURING THE AFOREMENTIONED TIMEFRAME. M60S-L70S DEWPOINTS ARE PROGGED
THRU THE PD, WHICH WL CONTRIBUTE TO HIGH CAPE VALUES.

WITH LITTLE UPR SUPPORT THRU THE FCST PD...GOOD CONVECTION
ORGANIZATION WL BE LIMITED. ONLY SVR POTL WL COME IN THE FORM OF
PULSE-TYPE MULTICELL STORMS, AND/OR THE LINEAR COLD-POOL MODE.

KEPT MONDAY AND TUE DRY ATTM. WL HAVE TO SEE HOW MID LVL CLOSED LOW
DVLPS AND MOVES BEFORE INSERTING POPS. MAY MOVE JUST FAR ENUF SE BY
THEN TO PRECLUDE ANY RAFL.

AS FAR AS TEMPS GO THRU THE FCST PD...MAINLY MID 80S DURING THE DAY
AND 60S AT NIGHT IN THIS STAGNANT PATTERN. MODERATE-HIGH DEWPOINTS
WL ACCOMPANY THESE MODEST TEMPERATURES. TEMPERATURES MAY
OCCASIONALLY BE AFFECTED BY DEBRIS CLOUDS/OCNL TSRA DURING THE
DAYLIGHT HOURS...WITH THESE LOCALES LOWER AND OTHER DRY AREAS
HIGHER.

AS ALWAYS...COMMENTS/OPINIONS WELCOME...
