AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
300 PM CDT SAT AUG 6 2011

.SYNOPSIS...
A WEAK COLD FRONT/WIND SHIFT AT 20Z EXTEND FROM NEAR NEWPORT THROUGH
NORTH PLATTE AND HAYES CENTER. STILL CONSIDERABLE STRATOCU REMAINS
ACROSS EASTERN HALF OF FORECAST AREA. NO STRONG UPDRAFTS OBSERVED BY
SATELLITE ATTM. TEMPS FROM THE LOWER 90S FRONTIER COUNTY TO NEAR 82
IN PARTS OF THE NORTHWEST. THE SURFACE BASED CAPES OF 2500-3500 J/KG
LOOK TO BE WASTED DUE TO STRONG CAPPING INVERSION AND LACK OF
FORCING ALOFT MAY INHIBIT ANY STORM DEVELOPMENT THROUGH LATE
AFTERNOON.

&&

.SHORT TERM (TONIGHT THROUGH TUESDAY)...
SURFACE FRONT BY EARLY THIS EVENING IS QUITE WEAK AND WILL BE A HILL
CITY THROUGH ORD AND ONEILL LINE. THE FRONT ITSELF IS NOT EXPECTED
TO BE MUCH OF A FOCUS. RATHER...THE UPPER TROUGH FROM NRN MINN AND
EASTERN DAKOTAS WILL SERVE AS MAIN FOCUS. ISOLATED STORMS MAY
BACKBUILD INTO EASTERN AND SCTRL NEBR AND POSSIBLY INTO FAR
SOUTHEASTERN ZONES. ALSO A FEW SHOWERS/STORMS FIRING IN THE HIGHER
TERRAIN OF SERN WY/NERN CO MAY SURVIVE INTO ERN PNHDLE/SWRN NEBR
THIS EVENING. THEN AFTER MIDNIGHT...ELEVATED CONVECTION POSSIBLE AS
A MID LEVEL DISTURBANCE TRACKS INTO WRN NEBR WITH A SLIGHT CHC FOR
WRN HALF OF ZONES. THIS WILL KEEP CHANCES IN SUNDAY MORNING. THERE
MAY BE AN END/LULL FROM EARLY TO MID AFTERNOON AS NEXT DISTURBANCE
ALOFT TO EFFECTIVELY TRIGGER STORMS IN THE PANHANDLE LATE AFTERNOON
WHICH WILL TRACK EAST INTO SUNDAY NIGHT. HAVE RAISED POPS TO 30-40
PERCENT RANGE ALL AREAS. HIGH TEMPS WILL BE HIGHLY DEPENDENT ON
ULTIMATE CONVECTIVE DEVELOPMENT...AS WELL AS REMNANT CLOUD REMAINS
ON SUNDAY AND MONDAY...WITH HIGHS RANGING IN THE 80S EACH DAY.

MORE POTENT COLD FRONT ARRIVES ON MONDAY WITH 30 POPS CENTRAL AND
EAST THROUGH THE DAY...CHANCES TO DIMINISH TO MAINLY SLIGHT CHANCE
MONDAY NIGHT AS WEAK UPSLOPE FLOW DEVELOP INTO TUESDAY. THIS
COMBINED WITH FAST WESTERLIES ALOFT SHOULD BRING A SLIGHTLY BETTER
CHANCE AND COVERAGE FOR TUESDAY AFTERNOON/TUESDAY NIGHT. HIGHS
TUESDAY ALSO TO BE SLIGHTLY COOLER IN THE UPPER 70S TO LOWER 80S.

.LONG TERM (WEDNESDAY THROUGH SATURDAY)...
THOUGH MODELS HAVE THEIR DIFFERENCES THEY CONTINUE TO INDICATE THE
SRN PLAINS UPPER RIDGE WILL WEAKEN AND RETROGRADE WESTWARD TO A
POSITION IN THE FOUR CORNERS REGION BY SATURDAY. THE WEATHER PATTERN
WILL BE LESS ACTIVE...WITH MAINLY SLIGHT CHANCES THROUGH THE LONGER
TERM. TEMPERATURES WILL ALSO REMAIN BELOW NORMAL WITH UPPER 70S
WEDNESDAY...MODERATING TO THE LOWER/MID 80S BY FRIDAY AND SATURDAY.

&&

.AVIATION...
AVIATION CONCERNS RATHER QUIET THROUGH MID-DAY SUNDAY. A FRONT
MOVING ACROSS CENTRAL NEBRASKA WILL LIKELY SPARK CONVECTION LATER
THIS AFTERNOON...BUT THIS IS EXPECTED TO BE ACROSS EASTERN NEBRASKA
AND SHOULD NOT AFFECT THE KLBF OR KVTN TERMINALS. WINDS WILL
EVENTUALLY  SWITCH FROM THE NORTHWEST BACK TO AN EASTERLY DIRECTION
BY SUNDAY MORNING. FORECAST MODELS ARE INDICATING THAT PRECIPITATION
WILL DEVELOP OVER SOUTHWEST SOUTH DAKOTA AND THE NEBRASKA PANHANDLE
OVERNIGHT TONIGHT THEN SHIFT EAST SUNDAY MORNING. HAVE NOT ADDED
THIS TO THE FORECAST BUT WILL MONITOR AND IF TREND CONTINUES MAY
NEED ADD THIS POTENTIAL INTO THE FORECAST FOR THE MORNING HOURS.

.LBF WATCHES/WARNINGS/ADVISORIES...NONE.
