AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORTH PLATTE NE
621 AM CDT SUN JUN 7 2015

.UPDATE...
ISSUED AT 523 AM CDT SUN JUN 7 2015

A NEW FORECAST IS IN PLACE WHICH USES MORE OF THE RAP AND HRRR
MODELS FOR SCATTERED THUNDERSTORMS TODAY. A NOTE FROM NESDIS
SUGGESTS HEAVY RAINFALL POTENTIAL WITH PWAT AROUND AN INCH ACROSS
THE PANHANDLE THIS MORNING. IF THE HRRR IS CORRECT THE MCS ACROSS
THE PANHANDLE WILL SWEEP EAST THIS MORNING AND BE FOLLOWED BY A
SECOND WEAKER MCS THIS AFTN ACROSS THE SANDHILLS ASSOCIATED WITH A
NRN STREAM DISTURBANCE ACROSS NRN WYOMING THIS MORNING.

&&

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 320 AM CDT SUN JUN 7 2015

THE RAP AND HRRR FORECAST AN ALL-OUT METEOROLOGICAL CONFLAGRATION
OF TSTMS AND HEAVY RAIN TODAY ACROSS SWRN NEB. SATELLITE AND RADAR
INDICATE A MUCH MORE STABLE PATTERN. THE UPPER LOW ACROSS THE WRN
U.S. SHOULD CONTINUE TO FLATTEN OUT TODAY STEERING A DISTURBANCES
OFF THE ROCKIES EAST AND SOUTHEAST THROUGH THE FCST AREA. POPS ARE
LIMITED TO 40 PERCENT WHICH MIGHT BE GENEROUS IN SOME AREAS GIVEN
THE POST FRONTAL ENVIRONMENT IN PLACE.

THE HRRR AND RAP ARE ACTUALLY THE BASIS FOR THE FORECAST BUT WE
SHIFT THE MODEL BLEND SOUTH ABOUT 70 MILES TOWARD THE SFC FRONT
ALONG THE KS-NEB BORDER AND LIMIT POPS TO 40 PERCENT.

SHOULD THE ADVECTIONS ADVERTISED BY THE RAP BEGIN TO MATERIALIZE
THEN POPS CAN BE RAISED. AS IT STANDS NOW THESE MODELS ARE FAR FROM
REALITY AND APPEAR TO BE BLINDLY DEVELOPING OUTFLOW DOMINANT SFC
BASED CONVECTION AT WILL.

HIGHS TODAY RISE INTO THE 70S TO NEAR 80. SOME CLOUDINESS FROM THE
UPPER LEVEL DISTURBANCES WILL HOLD DOWN HIGHS A BIT SOUTH AND
WEST...ESPECIALLY IF IT RAINS. IF THE RAIN DOES NOT MATERIALIZE THEN
HIGHS COULD BE AROUND 80 THROUGHOUT WRN AND NCNTL NEB. LOWS TONIGHT
FALL INTO THE 50S AS HIGH PRESSURE BUILDS THROUGH THE CNTL HIGH
PLAINS.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 320 AM CDT SUN JUN 7 2015

SIGNIFICANT LARGE SCALE RIDGING WILL DEVELOP ACROSS PAC NW AND INTO
THE NRN ROCKIES FOR THE FIRST PART OF THE WORK WEEK. MOST MID RANGE
MODELS SIMILAR IN THEIR HANDLING OF THIS TRANSITORY UPPER PATTERN
WHICH LEADS TO A DRY REGIME AND INCREASING TEMPS ACROSS THE HIGH
PLAINS FOR MONDAY AND TUESDAY. REMAINING ENERGY LEFT ACROSS THE
SOUTHWESTERN STATES EVENTUALLY GETS REORIENTED AND SHOVED
SOUTHEASTWARD ACROSS THE SRN PLAINS THRU TUESDAY. IN THE QUICKER NRN
STREAM ACROSS SRN CANADA AND THE NORTHERN PLAINS...PV ANOMALY
HANDLED SIMILARLY IN THIS REGION DRAGS A COLD FRONT ACROSS THE NRN
PLAINS TUESDAY AFTERNOON. AHEAD OF THIS FRONT A CLASSIC WRLY
DOWNSLOPE FLOW NEAR THE SFC PAIRED WITH COMPRESSIONAL WARMING WITH
NWRLY MID LEVEL FLOW PRECEEDING THE SFC FRONT WILL PUSH TEMPS INTO
THE 90S ESPECIALLY ACROSS NRN NEB WHICH WILL BE IN CLOSER PROXIMITY
TO THE FRONT. MODELS ALSO SIMILAR IN BRINGING THE FRONT THRU TUESDAY
LATE AFTERNOON AND EVE AND KEEPING IT DRY AS FORECAST SOUNDINGS SHOW
WARM MID LEVEL TEMPS LEADING TO LITTLE IN THE WAY OF POSITIVE CAPE
AND HENCE LITTLE POTENTIAL FOR DEEP MOIST CONVECTION WITH THE FRONT.
FRONT DOES STALL AS IT MEETS RESISTENCE FROM THE UPPER RIDGE OVER
THE PLAINS AND THE NRN STREAM PV ANOMALY OUT RUNS THE SRN PORTION OF
THE FRONT.

MODELS BEGIN TO DIFFER ON THEIR HANDLING OF UPPER FEATURES AND
ASSOCIATED FRONTAL POSITION BY WED AS THE PROGRESSIVE FLOW BEGINS TO
TRANSITION BACK TO UPPER TROUGHING ACROSS THE WEST. HEMISPHERICALLY
THERE ARE SOME INTERESTING TRANSITIONS TAKING PLACE AS THE POLAR LOW
BIFURCATES AND A MORE SIGNIFICANT AND ANOMALOUS UPPER LOW MOVES
THROUGH AK AND WRN CANADA BY THE END OF THE WEEK. MEANWHILE THE
REMNANTS OF HURRICANE BLANCA DOES GET PULLED INTO THE SWRN U.S. AND
CENTRAL ROCKIES. MOISTURE TRANSPORT VECTORS AT 320K PAIRED WITH
LAYER RH SUGGESTS MID LEVEL MOISTURE FROM BLANCA WILL GET DRAWN UP
INTO THE CENTRAL HIGH PLAINS THOUGH WILL BE ACCOMPANYING A SHEARING
WRN STATES TROUGH BY THURSDAY. THIS ADDED MOISTURE WILL BE AN
IMPORTANT PLAYER WED NIGHT INTO THURS AND ARRIVES IN TANDEM WITH A
STRENGTHENING LLJ ACROSS THE HIGH PLAINS. THE PREVIOUSLY MENTIONED
STALLED FRONT WILL BE RETURNING NWD AS A WARM FRONT BY THEN ALLOWING
A NARROW AREA OF HIGHER CAPE...BUT ALSO K INDEX VALUES APPROACHING
40 WHICH IS A KEY NUMBER WHEN CONSIDERING THE POTENTIAL FOR HEAVY
RAIN. AS EXPECTED PW VALUES INCREASE TO NEAR OR ABOVE THE 90TH
PERCENTILE ONCE AGAIN BY WED NIGHT AND THURSDAY FURTHER LEADING TO
CONFIDENCE IN THE POTENTIAL FOR HEAVY RAIN WITH WHATEVER
THUDERSTORM COMPLEXES CAN DEVELOP. TEMPS WILL BE TRICKY DUE TO
PRECIP CHANCES THROUGH THIS PERIOD...THOUGH OVERNIGHT LOWS THRU WED
NIGHT SHOULD REMAIN WARM.

MODEL DIFFS INCREASE TWD THE END OF NEXT WEEK AS THE AFOREMENTIONED
UPPER PATTERN UNDERGOES THE CHANGES. THE NEWD MOVING UPPER LOW DOES
DRAG A POTENT COLD FRONT SWD AS IT EXITS THE HIGH PLAINS...THEREFORE
A RETURN TO COOLER TEMPS LOOK MORE LIKELY BY FRIDAY. CONFIDENCE
DECREASES BY SATURDAY DUE TO SIGNIFICANT LARGE SCALE TIMING
DIFFERENCES.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z MONDAY MORNING)
ISSUED AT 620 AM CDT SUN JUN 7 2015

TWO COMPLEXES OF TSTMS ARE EXPECTED TODAY. THE STORMS SHOULD CLEAR
THE FCST AREA BY 00Z THIS EVENING. THE ONGOING COMPLEX ACROSS THE
SRN PANHANDLE SHOULD MOVE EAST AND CLEAR THE FCST AREA 19Z-21Z. A
SECOND AREA OF TSTMS MAY DEVELOP PER HRRR...ACROSS SWRN SD THIS
AFTERNOON AND MOVE SOUTHEAST FAIRLY QUICKLY.

VFR IS EXPECTED TONIGHT.
