AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
109 PM CDT SUN AUG 9 2015

.SYNOPSIS...
ISSUED AT 328 AM CDT SUN AUG 9 2015

AN AREA OF SHOWERS AND THUNDERSTORMS CONTINUES TO MOVE FROM CENTRAL
INTO EASTERN SOUTH DAKOTA ASSOCIATED NEAR A WEAK FRONTAL BOUNDARY
EXTENDING FROM SRN MINN THROUGH CENTRAL SOUTH DAKOTA INTO THE
WESTERN NEBR PNHDL. ANOTHER AREA OF THUNDERSTORMS REMAINS ANCHORED
ON THE CUSP OF A WARM FRONT FROM ECTRL NEBR INTO SWRN IA.

DEWPOINTS IN WRN NEBR RANGING IN THE MID TO UPPER 60S. PATCHY FOG
EXISTS FROM CENTRAL INTO NERN NEBR.

&&

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 328 AM CDT SUN AUG 9 2015

NEAR TERM CONCERN IS THE DEVELOPMENT OF PATCHY FOG UNTIL MID
MORNING. MODELS ARE IN FAIR AGREEMENT FOR FOG TO CONTINUE EXPANDING
WESTWARD INTO THE SERN PNHDL AND SWRN NEBR. SKIES LOOK TO BE PARTLY
SUNNY TODAY...WITH ANY STRATUS FROM EARLY MORNING FOG TO BURN OFF BY
10AM CDT. FCST HIGHS TODAY TO RANGE MAINLY FROM 86 TO 90 DEGREES
WITH A DOWNSLOPING WESTERLY WINDS HELPING TO MIX DOWN H85 TEMPS OF
23 TO 27C. SHOWERS AND THUNDERSTORMS ARE FORECAST TO DEVELOP THIS
AFTERNOON IN NCTRL NEBR SOUTHWARD ACROSS THE ERN HALF OF THE FA.
WHILE MID LEVEL LAPSE RATES ARE ONLY 6.5 TO 7C/KM...SBCAPES WILL
INCREASE TO 1500 TO 2000 J/KG EAST OF AN ANW THROUGH NORTH PLATTE
LINE. THE STRONGEST DEEP LAYER SHEAR WILL BE IN NERN FA RANGING FROM
40 TO 50 KTS SUPPORTIVE OF A FEW SEVERE STORMS. AREA FOR BEST STORM
DEVELOPMENT WILL BE FROM SCTRL SD INTO THE ERN HALF OF NCTRL NEBR.
ISOLATED DEVELOPMENT POSSIBLE FURTHER SOUTHWEST INTO LINCOLN AND
FRONTIER COUNTY.

STORM INITIATION THIS AFTERNOON WILL KEEP CHCS THIS EVENING ACROSS
THE ERN HALF OF FA EXITING FAR ERN ZONES AFTER 06Z. A FEW SEVERE
STORMS POSSIBLE THIS EVENING EAST OF VALENTINE THROUGH BURWELL WITH
A FEW STRONG STORMS POSSIBLE SOUTHWEST OF THIS LINE TO AROUND THE
NORTH PLATTE AREA.

UPPER RIDGING IS FORECAST ACROSS THE CNTRL AND NRN ROCKIES AS A
CLOSED LOW MOVES OVER THE HUDSON BAY REGION. SURFACE HIGH PRESSURE
WILL BUILD ACROSS THE NRN INTO THE CNTRL PLAINS OVERNIGHT. LOWS IN
WRN NEBR SLIGHTLY COOLER THAN RECENT NIGHTS RANGING FROM THE UPPER
50S TO LOWER 60S MOST AREAS.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 328 AM CDT SUN AUG 9 2015

MODEL GUIDANCE REMAINS IN GOOD AGREEMENT WITH THE AMPLIFICATION OF
A UPPER LEVEL RIDGE ACROSS THE INTERMOUNTAIN WEST EARLY NEXT WEEK.
THIS WILL FAVOR A GENERAL NORTHWEST STEERING FLOW ACROSS THE HIGH
PLAINS AND ADJACENT SANDHILLS THROUGH THE ENTIRE WORK WEEK. WHILE
THE FORECAST AREA REMAINS ON THE EASTERN PERIPHERY OF THE BUILDING
RIDGE AND PLENTIFUL LOWER TROPOSPHERIC MOISTURE WILL BE IN
PLACE...PRECIPITATION CHANCE WILL BE MAINLY TIED TO THE HIGHER
TERRAIN OFF TO OUR WEST. PRECIPITATION CHANCES ARE NOT NIL HOWEVER
AS THE OCCASIONAL PASSAGE OF A WEAK PERTURBATION MAY BE SUFFICIENT
TO GENERATE/MAINTAIN AN ISOLATED THUNDERSTORM. ONE SUCH
OPPORTUNITY ARRIVES LATE MONDAY OR EARLY ON TUESDAY...BUT THE
TREND OF THE MODELS CONTINUES TO CONFINE THE CHANCES ONLY ACROSS
OUR FAR SOUTHWEST. OTHERWISE THE NEXT NOTABLE SHOT A QPF ARRIVES
LATE WEEK WHEN A SHORTWAVE BREAKSDOWN THE UPPER RIDGE AND FORCES A
COLD FRONT ACROSS THE PLAINS.

POST FRONTAL CONDITIONS WILL PROMOTE A SLIGHT COOL DOWN ON
MONDAY...BUT THEREAFTER DAYTIME TEMPERATURES ARE FORECAST TO
GRADUALLY INCREASE AS HIGH PRESSURE BUILDS TO THE SOUTHWEST OF THE
FORECAST AREA AND INCREASING THERMAL ADVECTION SPREADS EAST FROM
THE ROCKIES.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 1250 PM CDT SUN AUG 9 2015

A WARM FRONT ACROSS NORTHERN NEBRASKA WILL BE THE FOCUS FOR
SCATTERED THUNDERSTORMS THIS AFTERNOON INTO THE EVENING
HOURS. OTHER MORE ISOLATED STORMS WILL BE POSSIBLE ACROSS WESTERN
AND SOUTHWEST AND INTO CENTRAL NEBRASKA. WINDS WILL BE LIGHT AND
VARIABLE EXCEPT STRONGER AND GUSTY NEAR ANY THUNDERSTORM. VFR WILL
BE THE RULE OUTSIDE ANY STORM ACTIVITY.
