AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORTH PLATTE NE
913 PM CDT SAT JUL 13 2013

.SYNOPSIS...
ISSUED AT 335 PM CDT SAT JUL 13 2013

A WESTWARD MOVING UPPER LEVEL LOW...CURRENTLY ACROSS THE LOWER
OHIO RIVER VALLEY IS EXPECTED TO MOVE WEST AND PRODUCE HEAVY RAIN
ACROSS PARTS OF THE FORECAST AREA SUNDAY AS IT INTERACTS WITH A
STATIONARY FRONT DRAPED FROM OGALLALA TO ONEILL. ONCE THIS
DISTURBANCE GOES BY DRIER AND COOLER AIR WILL MOVE INTO THE
FORECAST AREA AS LOW PRESSURE DEVELOPS ACROSS THE NRN HIGH PLAINS.
ANOTHER COLD FRONT COULD PRODUCE RAIN LATE NEXT WEEK.

&&

.UPDATE...
ISSUED AT 912 PM CDT SAT JUL 13 2013

UPDATED FORECAST TO DROP HEAT ADVISORY.

&&

.SHORT TERM...(TONIGHT)
ISSUED AT 335 PM CDT SAT JUL 13 2013

A SURFACE TROUGH CURRENTLY RUNS NORTHEAST FROM HAYES COUNTY TO
HOLT COUNTY...WITH MOST AREAS EXPERIENCING LIGHT WINDS. CLOUDS
HAVE BEEN PERSISTENT IN THE NORTH TODAY IN AN AREA OF WEAK MID
LEVEL FGEN AND ELEVATED INSTABILITY. THE AREA OF HIGHEST HEAT
INDICES STILL LOOK TO BE THE AREAS SOUTH OF THE CLOUD COVER. HEAT
ADVISORY CONTINUES THROUGH 9 PM.

THUNDERSTORM ACTIVITY IS EXPECTED IN THE VICINITY OF THE SURFACE
TROUGH THIS EVENING. THE SHEAR IN THIS AREA WILL BE LIMITED...BUT
CAPES WILL RUN 2000-3000 J/KG. THE BEST SHEAR WILL BE IN THE
NORTH...WHERE A FEW SEVERE THUNDERSTORMS WILL BE POSSIBLE.
THUNDERSTORMS ARE ALSO EXPECTED TO FIRE IN THE FAR WESTERN
PANHANDLE AND MOVE NORTHEAST INTO THE FORECAST AREA. AGAIN...THE
BEST CHANCE FOR SEVERE STORMS WILL BE IN THE NORTH WITH THE
PRIMARY THREAT BEING STRONG WINDS. HOWEVER...WITH PRECIPITABLE
WATER VALUES OF 1.5 TO 2 INCHES...HEAVY RAIN MAY BE AN ISSUE WITH
ANY STORMS.

THE LOW LEVEL JET WILL BE STRONG IN THE EAST AROUND 06Z TONIGHT.
GOOD CONVERGENCE AND MU CAPE WILL EXIST IN THE NORTH CENTRAL
FORECAST AREA AND MAY KEEP THUNDERSTORMS ACTIVE AFTER MIDNIGHT IN
THAT AREA.

.LONG TERM...(SUNDAY THROUGH SATURDAY)
ISSUED AT 335 PM CDT SAT JUL 13 2013

IT LOOKS LIKE THE NAM...GEMREG AND GFS MODELS HAVE SLOWED THE
WESTWARD PROGRESSION OF THE WESTWARD MOVING UPPER LEVEL LOW SUNDAY
AFTERNOON AND EVENING A BIT. THIS WOULD PRESENT THE BEST FORCING FOR
LOCALLY HEAVY RAINFALL FARTHER SOUTH AND EAST ACROSS THE FCST AREA.
WORSE...THE NORTHERN PORTION OF THE FRONT ACROSS NCNTL NEB HAS TAKEN
A EASTERLY JOG IN RESPONSE TO DEEP CONVECTION ACROSS THE NRN PLAINS
AND OVERALL THE FRONT IS ALIGNED MORE EAST TO WEST THAN PREVIOUS
MODEL RUNS HAD ADVERTISED. SO THERE IS SOME UNCERTAINTY AS TO THE
FORECAST LOCATION OF THE BEST RAINFALL SUNDAY.

PRECIPITABLE WATER INCREASES TO BETWEEN 1.60 AND 2.00 INCHES SUNDAY
WHICH IS NEAR OR ABOVE THE 99TH PERCENTILE STRONGLY SUGGESTING
LOCALLY HEAVY RAINFALL WILL OCCUR 25 MILES EAST AND WEST OF A LINE
FROM ROUGHLY KOGA TO KVTN. GIVEN THE CURRENT LOCATION OF THE FRONT
AND THE POTENTIAL FOR ADDITIONAL MODEL ERRORS WITH THE LOCATION OF
THE FRONT...THIS AREA OF HEAVY RAINFALL COULD STRETCH FARTHER EAST
TOWARD OR INTO...KLBF...KBBW AND KONL. 12 HOUR RAINFALL TOTALS OF 1
TO 2 INCHES COULD OCCUR BUT THE POTENTIAL EXISTS FOR HIGHER AMOUNTS
IF ANY STORMS TRAIN OR BECOME ANCHORED. THE ECM...GFS AND NAM SHOW
STORM MOTIONS OF LESS THAN 10 KTS SUNDAY. THE MID AND UPPER LEVEL
WINDS BECOME LIGHT AND VARIABLE AS THE 500 MB TO 300 MB SHEAR AXIS
NORTH OF THE UPPER LOW MOVES ACROSS THE FCST AREA.

GIVEN THE QUASI BAROTROPIC NATURE OF THE ATMOSPHERE...WEAK WINDS
ALOFT...500 MB TEMPS AROUND -5C AND WARM CLOUD RAIN PROCESSES TO 10
KFT OR HIGHER AS INDICATED IN BUFKIT...LOCALLY HEAVY RAINFALL SHOULD
DEVELOP. THE PROGRESSIVE NATURE OF THE WESTWARD MOVING UPPER
LOW PRECLUDES FLOODING CONCERNS AT THIS TIME BUT THE POTENTIAL FOR
FLASH FLOODING WILL CONTINUE TO BE EVALUATED IN LATER FORECASTS.

THE UPPER LEVEL DISTURBANCE SHOULD MOVE OFF TO THE WEST AFTER
MIDNIGHT SUNDAY EVENING WITH SUBSIDENCE AND DRIER AIR MOVING INTO
THE FORECAST AREA FROM THE SOUTH AND EAST. THIS SETS THE STAGE FOR
SUNNY SKIES...COOLER AND DRIER CONDITIONS MONDAY AND TUESDAY. HIGHS
BOTH DAYS SHOULD REACH INTO THE MID 80S WITH SOUTH WINDS. LOW
PRESSURE WILL DEVELOP ACROSS THE NORTHERN HIGH PLAINS AND MUCH OF
THIS RETURN FLOW IS RAIN COOLED OUTFLOW ORIGINATING FROM AREAS EAST
OF THE MISSOURI.

TUESDAY NIGHT THROUGH SATURDAY NIGHT...
THE FORECAST AREA WILL REMAIN UNDER THE NORTHERN PERIPHERY OF A
SUBTROPICAL HIGH STRETCHING ACROSS THE U.S.. 500 MB WINDS ARE LESS
THAN 20 KT AND H500 MB TEMPERATURES OF -5C TO -7C ACROSS THE FCST
AREA. A SLIGHT COOLING IS INDICATED FRIDAY AND SATURDAY AND
PRECIPITABLE WATER INCREASES TO ABOVE 1.5 INCHES AT TIMES FRIDAY AND
SATURDAY. THIS COMBINED WITH A WEAK UPPER LEVEL DISTURBANCE AND A
STALLED FRONT SHOULD PRODUCE ISOLATED TO SCATTERED TSTMS DURING THIS
TIME. THE ECM AND GFS HAVE SPED UP THE COLD FRONT AND NOW PROG IT TO
DROP THROUGH THE FCST AREA THURSDAY NIGHT AND BECOME STATIONARY
ACROSS KS SATURDAY. SO IT WOULD APPEAR CONDITIONS COULD BECOME
FAVORABLE FOR THUNDERSTORM ACTIVITY LATE NEXT WEEK.

AHEAD OF THE COLD FRONT...H10-5 THICKNESSES RISE TO 585-590 DM
THURSDAY AND H850 TEMPS TO NEAR 30C. THIS WOULD SUPPORT 90S FOR
HIGHS THURSDAY ASSUMING RAIN FALLS SUNDAY...OTHERWISE HIGHS NEAR 100
THURSDAY COULD DEVELOP. 580-585 DM THICKNESSES ARE EXPECTED
WEDNESDAY FOR HIGHS IN THE LOWER 90S.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING)
ISSUED AT 642 PM CDT SAT JUL 13 2013

THUNDERSTORMS WILL CONTINUE TO DEVELOP ACROSS THE NEBRASKA
PANHANDLE AND WESTERN NEBRASKA TONIGHT. STRONG AND VARIABLE WINDS
VRB25G40KTS IN THE VICINITY OF THUNDERSTORMS. SURFACE LOW PRESSURE
IS DEEPENING IN THE VICINITY OF KMCK. VFR CONDITIONS EXPECTED
THROUGH THE NIGHT EXCEPT IN THE VICINITY OF THUNDERSTORMS.
WIDESPREAD SHOWERS AND THUNDERSTORMS ARE EXPECTED OVER NORTHERN
NEBRASKA ON SUNDAY WITH CEILINGS LOWERING INTO MVFR THROUGH THE
AFTERNOON.
