AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
305 PM CDT THU AUG 13 2015

.SYNOPSIS...
ISSUED AT 305 PM CDT THU AUG 13 2015

HAND ANALYSIS OF THE 500MB LEVEL REVEALS A TYPICAL AUGUST PATTERN
ACROSS THE CENTRAL HIGH PLAINS.  HIGH PRESSURE REMAINS ANCHORED
ACROSS THE DESERT SOUTHWEST...WITH RIDGING EXTENDING NORTH ACROSS
THE SPINE OF THE ROCKIES TOWARD THE PACIFIC NORTHWEST.  A LONGWAVE
TROUGH IS ANALYZED OVER THE EASTERN THIRD OF THE CONUS WITH ANOTHER
TROUGH OFF THE WESTERN COAST.  THE LARGEST HEIGHT RISES OVER NORTH
AMERICA WERE LOCATED NEAR THE TANANA BASIN...EXTENDING EAST TO
YUKON.  HEIGHT FALLS OF 50DM WERE ANALYZED OVER EASTERN HUDSON BAY.
A BELT OF ENHANCED MID-LEVEL FLOW IS NOTED JUST TO THE LEE OF THE
CALIFORNIA LOW...WHICH NOSES NORTH ALONG THE PAC NW COAST.
SUBJECTIVE ANALYSIS OF THE SURFACE INDICATES A WEAK TROUGH EXTENDING
SOUTH FROM A LOW OVER CENTRAL SOUTH DAKOTA ACROSS THE CENTRAL
SANDHILLS AND SOUTHWEST NEBRASKA WITH HIGH PRESSURE WELL OFF TO THE
WEST.  AS OF 16Z...WEAK CONVECTION CONTINUES ACROSS THE INTERIOR OF
SOUTH DAKOTA...BUT A FEW SHOWERS HAVE DEVELOPED SOUTH NEAR
MERRIMAN.

&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 305 PM CDT THU AUG 13 2015

FORECAST CHALLENGE IS POPS TONIGHT. SURFACE BOUNDARY EXTENDS FROM
NEAR VALENTINE SOUTHWEST TO THE HYANNIS AREA...THEN SOUTH TO THE
WEST OF HIGHWAY 61. THE SOUTHERLY WINDS HAVE ADVECTED MOISTURE NORTH
WHERE DEWPOINTS ARE INTO THE UPPER 60S TO LOWER 70S INTO NORTH
CENTRAL NEBRASKA AHEAD OF THE SURFACE TROUGH. CURRENT LAPS SHOW CAPE
VALUES AROUND 4000 J/KG NEAR THE THEDFORD AREA. SATELLITE SHOWS CU
FIELD INCREASING ACROSS THE NORTH WITH FINE LINE EXTENDING SOUTH TO
NEAR THE IMPERIAL AREA. THUNDERSTORM INITIATION EXPECTED BY 4 PM CDT
WITH THUNDERSTORMS ONGOING ALONG AND EAST OF THE SURFACE BOUNDARIES
THEN MOVE SOUTHEAST THIS EVENING BY 14/00Z. SEVERE THUNDERSTORMS ARE
POSSIBLE OVER PARTS OF THE NORTH CENTRAL AND SOUTHWEST...WITH THE
SEVERE IMPACTS OF LARGE HAIL AND DAMAGING WINDS. THE SHORT TERM
MODELS CREATES SOME UNCERTAINTY IN AREAL EXTENT OF CONVECTION...WITH
THE UPPER SUPPORT MOVING EAST THIS EVENING SO THE NAM SOLUTION
GENERALLY FOLLOWED.

OVERNIGHT INTO FRIDAY THE UPPER RIDGE AXIS BUILDS EAST FOR QUIET
DAY. TONIGHT LOW TEMPERATURES IN THE 60S AND HIGH TEMPERATURES
FRIDAY MAINLY IN THE 90S.

.LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 305 PM CDT THU AUG 13 2015

UPPER LEVEL TROUGH WILL TRANSLATE EAST ACROSS THE PAC NW TOWARD THE
THE CENTRAL CANADIAN PRAIRIES THIS WEEKEND.  THE WAVE WILL BREAKDOWN
THE UPPER RIDGE TO THE SOUTHWEST AND EVENTUALLY FORCE A COLD FRONT
ACROSS THE HIGH PLAINS.  THE MODELS REMAIN FIXED ON A SOLUTION WHERE
AFTERNOON AND EVENING CONVECTION DEVELOPS SATURDAY...WITH ADDITIONAL
STORMS POSSIBLE INTO EARLY MONDAY AS THE FRONT STALLS OVER THE
REGION.  DESTABILIZATION OF THE LOWER TROPOSPHERE WILL OCCUR
YIELDING UPWARDS TO 2000 J/KG OF SBCAPE.  SHEAR IS NOT OVERLY
IMPRESSIVE...BUT WOULD MARGINALLY SUPPORT A FEW ORGANIZED STORMS
SATURDAY AFTERNOON AND EVENING. AN INCREASING LLJ MAY ALLOW STORMS
TO CONTINUE INTO THE OVERNIGHT.  SUNDAY SHEAR LOOKS A BIT MORE
FAVORABLE...BUT INSTABILITY WILL BE LESS OWING TO COOLER
TEMPERATURES AND CLOUDS.

EARLY NEXT WEEK THE RIDGE AMPLIFIES NORTH ONCE AGAIN ACROSS THE HIGH
PLAINS IN RESPONSE TO A STRONG TROUGH DEEPENING OVER THE PAC NW.
THE TROUGH WILL EVENTUALLY PROCEED TO THE EAST...KEEPING THE PATTERN
UNSETTLED FOR THE PLAINS THROUGH LATE NEXT WEEK.  THERE IS
CONSIDERABLE UNCERTAINTY ON HOW THE TROUGH WILL PLAY OUT.  THE
ENSEMBLES ARE ALL OVER THE PLACE...THUS THE CR_BLENDED POP FORECAST
FOR NEXT WEEK WAS LEFT LARGELY AS IS.
