AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORTH PLATTE NE
620 AM CDT THU JUN 4 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 338 AM CDT THU JUN 4 2015

TODAY AND TONIGHT...ALL MODELS SHOW A 300MB WAVE MOVING THROUGH COLO
THIS MORNING. DONT BOTHER LOOKING BELOW THAT LEVEL. THE MODELS ARE
VACANT AT 500MB. THUS IT APPEARS SOME UPPER LEVEL SUPPORT WILL MOVE
THROUGH THE FCST AREA FROM SOUTHWEST TO NORTHEAST TODAY SUPPORTING
SCATTERED TSTMS. DEPENDING ON HOW THE LONG HEAVY CONVECTION LASTS
ACROSS SERN NEB THIS MORNING COULD PLAY A ROLE IN THE COVERAGE OF
STORMS ACROSS NCNTL NEB THIS AFTERNOON. THE RAP MODEL MOVES THIS
CONVECTION INTO MISSOURI BY 15Z WHICH WOULD ALLOW FOR MOISTURE
TRANSPORT TO RESUME ACROSS NCNTL NEB WITH PWAT INCREASING TO 1.25 TO
1.5 INCHES. STILL THE BEST INSTABILITY...STEEPEST LAPSE RATES AND
HIGHEST K INDICES WILL LIKELY BE ACROSS SRN NEB WHERE AN H850MB WARM
FRONT WILL BE LOCATED. THE FRONT WILL TRY AND LIFT NORTH TONIGHT
PROVIDING FOCUS FOR ANOTHER ROUND OF TSTMS ACROSS SWRN NEB.

THE FCST CARRIES A 20 TO 50 POP WITH THE BETTER CHANCES EAST OF
HIGHWAY 83 TODAY AND ACROSS SWRN NEB TONIGHT.

HIGHS TODAY RISE INTO THE 70S TO NEAR 80. SIGNIFICANT MID LEVEL
CLOUDINESS IS EXPECTED WITH SOME CLEARING SOUTH. HIGH PRESSURE
ACROSS MANITOBA AND WRN ONTARIO WILL BUILD VERY SLOWLY EAST. THE NAM
AND GEM REG MODELS ARE WARMER WITH HIGHS AROUND 80. THE FORECAST
FOLLOWS THE MIDDLE OF THE ROAD.

SPC OUTLOOKS THE SOUTH AND WEST FOR SLIGHT CHANCES OF SEVERE
WEATHER. ELSEWHERE ITS 5 PERCENT. A 60KT 300MB SPEED MAX WILL MOVE
THROUGH WITH THE UPPER LEVEL WAVE TODAY. THESE STRONG WINDS ARE
STILL IN PLACE ACROSS THE SOUTH AT 21Z. THE RAP SHOWS 3000J/KG MIXED
LAYER CAPE AND 40KT OF 0-6KM BULK SHEAR ALONG AND SOUTH OF
INTERSTATE 80. BY 20Z THE CAP IS GONE HOWEVER SO IS THE FORCING. THE
FORCING IS NORTH OF THIS AREA SO A LOWER POPS IS IN PLACE SOUTH THIS
AFTN...20-30 PERCENT.

NEEDLESS TO SAY...SOME STORMS WILL BE CAPABLE OF LOCALLY HEAVY
RAINFALL. THE REMNANTS OF PACIFIC HURRICANE ANDRES APPEAR TO STILL
BE ACROSS THE SRN ROCKIES TODAY.

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 338 AM CDT THU JUN 4 2015

THE EXTENDED FORECAST CONTINUES TO BE ACTIVE AS THE UPPER LEVEL
PATTERN FAVORS SEVERAL OPPORTUNITIES FOR PRECIPITATION...AT LEAST
THROUGH THE UPCOMING WEEKEND.  THOUGH THE CONVECTIVE PRECIPITATION
CHANCES COME NEARLY EVERY PERIOD IN THE EXTENDED...THE FORECAST IS
NOT ANTICIPATED TO BE A COMPLETE WASHOUT...AS THE PRECIPITATION
CHANCES WILL BE TIED TO KEY MESOSCALE FEATURES AND THE PASSAGE OF
SUBTLE MID-LEVEL DISTURBANCES.  THUS FORECAST CONFIDENCE IS LESS
THAN IDEAL AT THIS POINT...BOTH CONCERNING TIMING AND LOCATION OF
ANY POTENTIAL QPF.

BEGINNING LATE WEEK...A FAIRLY AMPLIFIED PATTERN WILL EXIST AND
CONTINUE INITIALLY INTO COMING WEEKEND.  THE UPPER LEVELS WILL BE
CHARACTERIZED WITH A DEEP TROUGH OVER THE WESTERN CONUS...RIDGING
ATOP THE PLAINS AND A TROUGH OVER THE EASTERN THIRD OF THE CONUS.
THE CENTRAL CONUS RIDGE DOES UNDERGO A BREAKDOWN /FLATTENING/ AS A
NORTHERN PLAINS WAVE MOVES THROUGH THE AREA ON SATURDAY...WHICH
PROVIDES FOR A GREATER DIRECT INFLUENCE OF SOUTHWEST FLOW FROM THE
WESTERN CONUS TROUGH.  A DISTURBANCE IS SUGGESTED TO PASS THROUGH
SOUTHWEST FLOW LATE FRIDAY NIGHT INTO SATURDAY AND PROVIDE FOR A
SOLID OPPORTUNITY OF QPF.  THE MODELS DURING THIS TIME PERIOD SHOW A
FAIRLY ROBUST MCS TRAVERSE FROM NORTHEAST COLORADO/WESTERN PANHANDLE
NORTHEAST ACROSS MUCH OF THE FORECAST AREA.  WITH THIS IN MIND THE
POP FORECAST WAS TRENDED UPWARD INTO LIKELY AND HIGH END CHANCE.

THE RIDGE FLATTENS FURTHER SATURDAY INTO SUNDAY...BUT THE MODELS
CONTINUE TO KEY ON CONVECTION INITIATING OFF WARM FRONT/SUBTLE
DISTURBANCES...CHANCE POPS WERE MAINTAINED THROUGH THE WEEKEND.

THE MODELS THEN SHEAR THE TROUGH TO THE WEST OF THE FORECAST AREA
EARLY NEXT WEEK...WITH THE LOW RE-FOCUSING OFF THE SOCAL COAST...YET
THERE REMAINS A PRECIPITATION SIGNAL AS A SYNOPTIC BOUNDARY REMAINS
IN THE REGION...AND ADDITIONAL LOW AMPLITUDE WAVES CROSS THROUGH THE
FLOW.  BY MID WEEK...THERE ARE INDICATIONS THAT A BROAD RIDGE WILL
DEVELOP LEADING TO DRYING CONDITIONS.

EPISODES OF SEVERE WEATHER WILL BE POSSIBLE THROUGH AT LEAST THIS
WEEKEND...HOWEVER AT THIS POINT THE GREATER CONCERN COMES WITH THE
POTENTIAL OF HEAVY RAINFALL....ESPECIALLY TRUE FRIDAY NIGHT INTO
SATURDAY WHEN PWATS INCREASE IN EXCESS OF AN 1.75" AT KLBF AND WARM
CLOUD DEPTHS INCREASE TO NEAR 3000 METERS.  THE MOISTURE IS A
COMBINATION OF SOLID RETURN FROM THE GULF AND THE REMNANTS OF ANDRES
OFF BAJA.

SLIGHTLY BELOW AVERAGE TO NEAR NORMAL TEMPERATURES ARE FORECAST
THROUGH THE EXTENDED WITH THIS ACTIVE PATTERN...HOWEVER BY DAY 6
/TUESDAY/...TEMPERATURES MAY RETURN TO SLIGHTLY ABOVE AVERAGE.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z FRIDAY MORNING)
ISSUED AT 619 AM CDT THU JUN 4 2015

VFR/MVFR CIGS SHOULD IMPROVE TO VFR 16Z-18Z THIS MORNING. AN UPPER
LEVEL DISTURBANCE MOVING NORTHEAST THROUGH COLORADO IS EXPECTED TO
TRIGGER SCATTERED TSTM THIS MORNING. THE MCS ACROSS SWRN SD COULD
BRUSH NRN NEB THIS MORNING AFFECTING KVTN. THE MODELS SUGGEST THIS
TSTM ACTIVITY WOULD LIFT INTO SD AND REMAIN NORTH OF NEB.

MEANWHILE THE ACTIVITY ACROSS SRN NEB WILL MOVE MOSTLY EAST-
NORTHEAST. THUS IT IS POSSIBLE MOST OF THE FCST AREA COULD REMAIN
STORM FREE THROUGH 21Z. THEREAFTER...ALTHOUGH THE FORCING IS
WEAK...ISOLATED TO PERHAPS SCATTERED THUNDERSTORMS MAY DEVELOP
FROM 22Z ONWARD ACROSS WRN AND SWRN NEB. ACTIVITY MAY LAST INTO
THE EVENING ACROSS SWRN NEB AND WEAKEN 06Z-09Z. MVFR/IFR CIGS WILL
LIKELY DEVELOP 03Z ONWARD.
