.DISCUSSION...
THE SUBTROPICAL MOISTURE PLUME LOCATED ACROSS THE WRN U.S. CONTINUES
TO RICHEN WITH MOISTURE AS REMNANT "DORA" AND OTHER DISTURBANCES
ACROSS THE TROPICS EXPERIENCE WEAK TO MODERATE SHEAR FROM THE
WESTERLIES. THIS BELT OF MOISTURE IS EXPECTED TO MEANDER NORTH AND
SOUTH ACROSS THE CNTL AND NRN PLAINS AS DISTURBANCES TRACK THROUGH

PRODUCE ROUNDS OF ISOLATED TO SCATTERED THUNDERSTORMS. THE SPC HAS
OUTLOOKED PARTS OF THE FCST AREA FOR ISOLATED SEVERE THUNDERSTORMS
LATE TODAY...WEDNESDAY AND THURSDAY. THE NAM12 SUGGESTS THE POTENTIAL
FOR CONVECTIVE DEVELOPMENT ACROSS THE BLACK HILLS LATE FRIDAY. A
BLEND OF THE GFS AND NAM WAS USED FOR POPS...TEMPS...AND QPF. NO
SIGNIFICANT HEAT ISSUES ARE EXPECTED THROUGH FRIDAY AS DEW PTS
HOVER IN THE 60S AND TEMPS REMAIN BELOW 100F.

MODEST 35 TO 40KT 0-6KM BULK SHEAR AND MLCAPE/800MB CAPE NEAR OR

ISOLATED COVERAGE. NONETHELESS...WIND DAMAGE AND LARGE HAIL ARE THE
PRIMARY CONCERN LATE IN THE AFTERNOON AND DURING THE EVENING HOURS.

OTHERWISE STORMS ARE EXPECTED TO DEVELOP LATE THIS AFTERNOON OR THIS
EVENING ACROSS THE WEST WITH A MCS DEVELOPING AND SWEEPING THE FCST
AREA OVERNIGHT. THIS SYSTEM SHOULD BUILD A WEAK MESOHIGH AND COLD
FRONT WHICH BECOME THE FOCUS ADDITIONAL STORM DEVELOPMENT ACROSS
WESTERN NEB WEDNESDAY THROUGH FRIDAY.

SATURDAY THROUGH TUESDAY...THE GENERAL CONSENSUS OF THE 12Z GEM...
GFS...GEF 00Z ECMWF AND ENSEMBLE SUGGEST THE UPPER LEVEL RIDGE ACROSS

AREA NEXT TUESDAY. ISOLATED POPS ARE IN THE FCST MONDAY AFTN/MONDAY
NIGHT FOR THE APPROACH OF THE COLD FRONT. OTHERWISE HIGHS IN THE 90S
ARE EXPECTED ALL DAYS EXCEPT UPPER 80S ON TUESDAY BEHIND THE FRONT.

VFR CONDITIONS THIS EVENING. THEN A SHORT WAVE WILL MOVE ACROSS THE
AREA WITH A CHANCE FOR STRONG THUNDERSTORMS THAT WILL BRING GUSTY
WINDS AND POSSIBLY SOME HAIL. MVFR AND POSSIBLY BRIEF IFR
VISIBILITIES ARE POSSIBLE WITH THE THUNDERSTORMS. MOST OF WESTERN
AND NORTH CENTRAL NEBRASKA COULD BE EFFECTED...INCLUDING KLBF AND
KVTN TERMINALS...THUS HAVE INCLUDED IN THE 18Z TAF. FOLLOWING THE
CONVECTION WILL BE A RETURN TO VFR CONDITIONS THAT ARE EXPECTED TO
CONTINUE THE REST OF THE NIGHT AND INTO WEDNESDAY.

&&

THE NORTH PLATTE RIVER MONDAY AFTERNOON. THIS WILL REACH NORTH
PLATTE STARTING ON WEDNESDAY AND WILL INCREASE TO 6.4 FEET...OR 0.4
FEET...BY EARLY FRIDAY.

THE PLATTE RIVER AT BRADY NORTH CHANNEL DROPPED BELOW FLOOD STAGE
EARLIER TODAY AND WILL CONTINUE TO DROP OVER THE NEXT SEVERAL
DAYS...THUS THE FLOOD WARNING WAS CANCELED. THE RIVER LEVEL IS
EXPECTED TO CONTINUE TO FALL...HOWEVER BY THE END OF THE WEEK...THE
