AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
350 AM CDT MON JUN 14 2004

.DISCUSSION...
TSTM COVERAGE AND STRENGTH REMAIN MAIN FORECAST CHALLENGE BOTH IN
SHORT AND INTERMEDIATE TERM.

SHORT TERM...INTENSE SHORTWV TROF/VORT MAX MOVG ACRS SERN SD DRIVING
SFC FNT AND SCT STRONG/SVR THUNDERSTORMS ACROSS NERN NEBRASKA...NOT
HANDLED THE BEST WITH YDAS PROGS...SPCLY THE UPR SYSTEM AND QPF.  WL
BE DOING LAST MINUTE ADJUSTMENT IN TSTM POPS/COVERAGE WITH EARLY
MORNING THUNDERSTORMS...BUT IT LOOKS LIKE MUCH OF THE ACTIVITY COULD
BE CONFINED TO FAR ECNTRL NEBR AND IA COUNTIES BY ISSUE TIME.  WL
KEEP SMALL POPS IN THIS MORNING ACROSS THE SOUTH HOWEVER AS FRONT
WILL BE PUSHING THROUGH HIGHER THETA E AIR.  FRONT SETTLES S OF MUCH
OF CWA THIS AFTN WITH AN APPARENT DECREASE CHANCE OF TSTMS.
HOWEVER...WL KEEP SMALL IN ACRS THE SE AS FRONT SHOULD LOSE ITS SWD
PUSH AND OUTFLOW BOUNDARIES HAVE BEEN RECENTLY CREATING RESULTS NOT
QUITE AS EXPECTED. MADE LTL CHANGE TO HIGHS.

TNGT INTO TUE NIGHT/EARLY WED. RATHER ACTIVE CONVECTIVE PERIOD FOR
CWA IN THE WORKS...ALTHOUGH BASED ON LATEST GFS/ETA LOOKS LIKE THE
WARM ADVCTN CONVECTION MAY BE DELAYED UNTIL MORE AFTER MIDNIGHT
LEADING INTO TUE AM.  ADJUSTED POPS A LTL TO REFLECT THIS.  SWING
SHIFT ALREADY BEGIN INCREASING POPS LATER TUE INTO TUE...AND BESIDES
SVR WEATHER...HEAVY RAIN ALSO WILL BECOME AN ISSUE.  DID NOT ISSUE A
FLOOD WATCH WITH MORNING PACKAGE...BUT WITH RECENT SIGFNT RAINS AND
LOW FLASH FLOOD INDICES THIS MAY HAVE TO BE ADDRESSED IF MODELS QPF
FCST REMAINS CONSISTENT AND ACTIVITY LOOKS LIKE IT WL LINGER FOR ANY
LENGTH OF TIME.  STILL SOME QUESTION ON HOW CONVECTIVE DEBRIS AND
ANY OUTFLOW BOUNDARIES AFFECT NEW DVLPMNT PREFRONTAL TUE SO DIDNT
CHANGE CONVECTIVE TIMING OR HIGHS TOO MUCH...IF ANY.

REST OF FCST...STRONGER UPR TROF SWINGING ACRS NRN PLAINS LATE TUE
WL BE DRIVING A STRONGER COLD FRONT THROUGH AND S OF CWA WED. THIS
HAS BEEN FAIRLY CONSISTENTLY ADVERTISED LAST SVRL RUNS SO LOWERED
HIGHS A LTL WED AND THU.  EVEN WITH SFC HIGH BUILDING INTO CNTRL
PLAINS...HARD TO RULE OUT PCPN FOR SURE AS A SERIES OF SHRTWV TROFS
CONTINUE PIVOTING THRU OR NEAR CWA.  SO MADE LTL/NO CHANGES TO POPS.
