AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
649 PM CDT FRI JUN 5 2015

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 335 PM CDT FRI JUN 5 2015

UPPER LEVEL PATTERN AS OF 20Z DEFINED BY A SLOW MOVING LOW OVER
SOUTHERN CALI AND A RIDGE AMPLIFYING IN THE CENTRAL/SOUTHERN
PLAINS. SOUTHWEST FLOW WAS ESTABLISHED BETWEEN THESE TWO FEATURES
WITH SEVERAL SHORTWAVE TROUGHS ROUNDING THE BASE OF THE UPPER
LEVEL LOW AND EJECTING NORTHEASTWARD TOWARD THE CENTRAL PLAINS.
THE SOUTHWEST FLOW HAS ALSO BEEN ABLE TO THE REMNANTS OF
HURRICANE ANDRES IN THE EASTERN PACIFIC...CREATING A MOISTURE
TAP NORTHWARD INTO THE CENTRAL AND EASTERN ROCKIES. AT THE
SURFACE AND CLOSER TO THE CWA AN AREA OF LOW PRESSURE WAS
CENTERED IN EASTERN CO...WITH A WARM FRONT EASTWARD INTO WESTERN
KS. EASTERLY UPSLOPE FLOW WAS IN PLACE OVER THE CWA TO THE NORTH
OF THE WARM FRONT.

SCATTERED AREAS OF LIGHT SHOWERS AND A FEW THUNDERSTORMS HAVE
DEVELOPED AND DISSIPATED THROUGH THE LATE MORNING AND EARLY
AFTERNOON HOURS ALONG OLD OUTFLOW BOUNDARIES...WITH UPPER LEVEL
SUPPORT FROM A PASSING SHORTWAVE. HOWEVER MOST OF THE CONVECTION
SO FAR TODAY HAS BEEN FOCUSED ALONG FRONT RANGE WHERE MOISTURE
CONVERGENCE HAS BEEN ENHANCED. NEXT SHORTWAVE MOVING OUT OF THE
FOUR CORNERS REGION WILL BEGIN TO IMPACT THE CWA BY THIS EVENING
AS THUNDERSTORMS REDEVELOP IN MULTIPLE AREAS. THE FIRST AREA OF
CONCERN IS ALONG THE FRONT RANGE AND EASTERN WYOMING...WHERE
STEERING FLOW ALOFT SHOULD BE STRONG ENOUGH TO MOVE THE
CONVECTION NORTH AND EAST TOWARD THE PANHANDLE TONIGHT. ANOTHER
AREA OF EXPECTED THUNDERSTORM DEVELOPMENT IS EASTERN CO/WESTERN
KS. LIGHTNING STRIKES ARE ALREADY BEING DETECTED IN NORTHEAST NEW
MEXICO/SOUTHEAST COLORADO...AND THIS TREND SHOULD CONTINUE AS THE
SHORTWAVE LIFTS NORTHWARD. EXPECTING THUNDERSTORMS EVENTUALLY
MAKING INTO SOUTHWEST NEBRASKA BY THIS EVENING WITH THE HELP OF A
STRENGTHENING LOW LEVEL JET...CONTINUING NORTHWARD THROUGH THE
OVERNIGHT HOURS. A FEW SEVERE STORMS WILL BE POSSIBLE GIVEN
EXPECTED DEEP LAYER SHEAR VALUES OF 30-35 KTS...HOWEVER PRIMARY
THREAT WITH ANY THUNDERSTORM ACTIVITY THREAT WILL BE LOCALIZED
HEAVY RAINFALL. DEEP PACIFIC MOISTURE STREAMING NORTHWARD INTO
THE CENTRAL ROCKIES WILL BEGIN TO ROUND THE TOP OF THE SOUTHERN
PLAINS RIDGE TONIGHT...OVER THE TOP OF ALREADY MOIST AIRMASS.
THIS WILL PUSH LOCAL PWATS TO NEAR CLIMATOLOGICAL RECORD VALUES
IN THE 1.25 TO 1.50 INCH RANGE...MORE TYPICAL FOR MID TO LATE
SUMMER. LATEST BUFKIT SOUNDINGS INDICATE THE POTENTIAL FOR
THUNDERSTORMS CAPABLE OF BEING EFFICIENT RAINFALL PRODUCERS WITH
SKINNY CAPE PROFILES AND A DEEP WARM LAYER.

FORECAST CONFIDENCE LOWERS BY SATURDAY AS MODELS ARE STRUGGLING
WITH THEIR RECOVERY FROM THE CONVECTIVE EPISODE OF FRIDAY NIGHT.
MOST LIKELY SCENARIO IS A COLD FRONT SLOWLY TRACK SOUTHEAST
ACROSS THE CWA DURING THE DAY. THUNDERSTORMS...POSSIBLY
SEVERE...DEVELOP IN THE VICINITY OF THE COLD FRONT FROM SOUTHWEST
INTO CENTRAL NEBRASKA BY LATE AFTERNOON AND EVENING AS ANOTHER
SHORTWAVE TROUGH PROVIDES LIFT OVER AN INCREASINGLY UNSTABLE
AIRMASS. SHOWERS AND THUNDERSTORMS WILL ALSO BE POSSIBLE IN THE
POST-FRONTAL ENVIRONMENT AS PLENTIFUL MOISTURE WILL STILL BE IN
PLACE.

.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 335 PM CDT FRI JUN 5 2015

LIKELY WILL HAVE A LINE OR A DEVELOPING LINE EARLY SATURDAY NIGHT
ALONG A SOUTHEASTWARD PROGRESSING COLD FRONT. MOISTURE STILL
PLENTIFUL ACROSS THE AREA SO ANY OUTFLOW BOUNDARY WILL HAVE THE
CAPABLE OF THUNDERSTORMS ELSEWHERE...BUT THE PRIMARY FOCUS WILL
BE THE COLD FRONT. ONCE AGAIN HAIL WILL BE A THREAT AND
WINDS...BUT WITH PWATS CONTINUING TO BE NEAR CLIMO
MAXIMUMS...HEAVY RAIN WILL BE POSSIBLE.

THE LINE SHOULD BE EAST OF THE CWA BY MIDNIGHT WITH SOME RESIDUAL
MOISTURE AND OUTFLOW BOUNDARIES TO BE THE MAIN CONCERN AND WILL
CONTINUE POPS POST FRONTAL. LOWS WILL CONTINUE TO BE MILD AS DEW
POINTS AND CLOUDS KEEP THEM FROM FALLING FAR.

SUNDAY MODELS ARE STRUGGLING ON POTENTIAL FOR LINGERING SHOWERS.
MODELS SOMEWHAT AGREE THERE SHOULD BE A BREAK FROM THE OVERNIGHT
MCS WITH REDEVELOPMENT OUT WEST LATE MORNING. THIS WILL SHIFT
EAST INTO THE AREA THROUGHOUT THE DAY...AND WILL INCREASE POPS
WEST TO EAST. SOME DRY AIR GETS DRAWN SOUTH FROM DEPARTING
LOW/COLD FRONT AND SHOULD KEEP PARTS OF N CENTRAL DRY.

MONDAY THE FRONT STALLS ACROSS KANSAS AND THE FRONT RANGE. THIS
WILL BE THE MAIN FOCUS OF THUNDERSTORMS...HOWEVER FLOW IS
WESTERLY/SOUTHWESTERLY WITH ANY HIGHER TERRAIN STORMS POSSIBLY
MOVING ACROSS SW NEB. LOW CONFIDENCE AND WILL KEEP POPS LOW.
TEMPS VARY DEPENDING ON CLOUDS AND HAVE GONE WITH A GUIDANCE
BLEND.

REST OF THE WEEK WILL SEE THE UPPER LEVEL SOUTHWEST FLOW
REDEVELOP AS THE RIDGE AMPLIFIES TO THE EAST. ALSO GOING TO
LIKELY SEE REMNANTS OF ANOTHER EAST PACIFIC HURRICANE GET DRAWN
NORTH ACROSS THE ROCKIES WITH A RETURN TO MORE OF AN ACTIVITY
WITH HEAVY RAIN POTENTIAL. AFTER A COUPLE OF DRY OR MOSTLY DRY
DAYS...POPS INCREASE FOR THURSDAY INTO FRIDAY. TEMPS SEASONALLY
WARM FOR MID WEEK WITH MORE SUN EXPECTED...THEN A COOL DOWN AS
CLOUDS/STORMS RETURN.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SATURDAY EVENING)

AGL. FOR THE KVTN TERMINAL...THUNDERSTORMS ARE POSSIBLE AFTER 04Z
THIS EVENING WITH THE THREAT PERSISTING THROUGH 09Z OVERNIGHT.
CIGS DOWN TO 2000 FT AGL AND VISBYS DOWN TO 4SM ARE POSSIBLE WITH

.HYDROLOGY...
ISSUED AT 335 PM CDT FRI JUN 5 2015

FLOOD CONTINUES ACROSS THE NORTH PLATTE...SOUTH PLATTE...AND
PLATTE RIVERS. SOME RESERVOIR RELEASES IN WYOMING WILL CAUSE THE
NORTH PLATTE TO RISE LATER NEXT WEEK...HOWEVER THEY WILL CONTINUE
TO DROP THE WEEKEND SO THE RISE MAY NOT EVEN REACH THE CURRENT
STAGE. HEAVY RAINFALL HAS FALLEN ACROSS THE SOUTH PLATTE BASIN IN
COLORADO AND ADDITIONAL RAINFALL...SOME AREAS TO SEE HEAVY
RAINFALL...THE NEXT COUPLE OF DAYS. THIS WILL ADD TO THE ALREADY
HIGH WATERS FROM SNOW MELT AND PREVIOUS RAINFALL. THUS ANOTHER
RISE ALONG THE SOUTH PLATTE AND PLATTE RIVERS IS EXPECTED NEXT
WEEK.
