AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
354 AM CDT SUN JUN 29 2014

.SYNOPSIS...
ISSUED AT 353 AM CDT SUN JUN 29 2014

H5 ANALYSIS FROM EARLIER THIS EVENING...HAD AN UPPER LEVEL LOW
OVER NORTHERN NORTH DAKOTA WITH A POSITIVE TILTED TROUGH
EXTENDING SWD INTO THE OZARKS. LOW AMPLITUDE FLOW EXTENDED WEST
TO THE PACIFIC COAST...WHILE EAST OF THE LOW...A RIDGE EXTENDED
UP THE EASTERN CONUS INTO SRN HUDSON BAY. WV IMAGERY AS OF 230 AM
CDT...HAS THE UPPER LEVEL LOW OVER SWRN MANITOBA WITH A NICE
SHORTWAVE OVER NRN SD...WITH CONVECTION NOTED OVER FAR NRN
NEBRASKA AND THE CENTRAL AND WESTERN SANDHILLS. ADDTL SUPPORT FOR
THESE SHOWERS AND THUNDERSTORMS...LIES WITH A NICE JET
STREAK...VISIBLE ON CURRENT WV IMAGERY. AT THE SURFACE...A TROUGH
OF LOW PRESSURE EXTENDED FROM EASTERN SOUTH DAKOTA...SOUTH INTO
NERN NEBRASKA...THEN SW INTO SWRN NEBRASKA...OR ROUGHLY ALONG A
LINE FROM WATERTOWN SOUTH DAKOTA...TO ONEILL NEBRASKA...TO JUST
WEST OF MCCOOK NEBRASKA. VERY MOIST AIR WAS PRESENT EAST OF THIS
FEATURE...WITH DEW POINTS IN THE 60S. WEST OF THE FEATURE...DEW
POINTS WERE IN THE 50S WITH LIGHT WESTERLY WINDS. TEMPERATURES AS
OF 3 AM CDT...RANGED FROM 61 AT THEDFORD AND VALENTINE...TO 66 AT
BROKEN BOW...OGALLALA AND IMPERIAL.

&&

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 353 AM CDT SUN JUN 29 2014

THUNDERSTORM CHANCES LATER TODAY AND TONIGHT AND THE THREAT FOR
SEVERE STORMS WILL BE THE MAIN FORECAST CHALLENGE OVER THE NEXT
24 HRS. FOR TODAY...WILL CONTINUE TO MONITOR THE LATEST RADAR
TRENDS FOR INCLUSION IN THE FORECAST THROUGH MID MORNING. AS IT
STANDS RIGHT NOW...THE LATEST HRRR MODEL...DOES LINGER SOME
CONVECTION IN EAST CENTRAL PORTIONS OF THE CWA THROUGH LATE
MORNING. BASED ON CURRENT RADAR TRENDS...THOUGHTS ARE THAT THE
HRRR IS TOO SLOW WITH PCPN EXITING THE FORECAST AREA THIS
MORNING. WITH THIS IN MIND...WILL END PCPN IN THE EAST BY MID
MORNING. LATER THIS AFTERNOON WITH SURFACE HEATING AND THE
APPROACH OF A SECONDARY UPPER LEVEL DISTURBANCE...SHOWERS AND
THUNDERSTORMS SHOULD FIRE INVOF OF THE BEFOREMENTIONED SURFACE
TROUGH. ATTM...AM EXPECTING THE SURFACE TROUGH TO MOVE LITTLE
TODAY...SO LOCATIONS ROUGHLY EAST OF A LINE FROM O'NEILL TO EAST
OF NORTH PLATTE...WILL BE UNDER THE GREATEST THREAT FOR
THUNDERSTORMS. SOME OF THESE STORMS MAY REACH SEVERE
LIMITS....ESPECIALLY OVER FAR EASTERN AREAS OF THE FORECAST AREA
WHERE CAPES WILL REACH 3000 TO 4000 J/KG THIS AFTERNOON.
ATTM...LARGE HAIL SEEMS TO BE THE MAIN THREAT IN FAR EASTERN
SECTIONS OF THE CWA PER DECENT CAPES IN THE -10 TO -30C LAYER AND
STRONG DEEP LAYER SHEAR. FURTHER WEST OF THE SURFACE
TROUGH...INSTABILITY AND AVAILABLE CAPE DECREASES QUICKLY...SO
ONLY A GENERAL THREAT FOR STORMS EXISTS. HIGHS TODAY WILL RANGE
FROM THE MIDDLE 80S IN THE NORTH AND EAST...WHERE BL MOISTURE IS
GREATEST...TO AROUND 90 IN THE SOUTHWEST WHERE DRIER BL CONDS
EXIST. FOR TONIGHT...THE THREAT FOR STORMS WILL LINGER INTO THE
OVERNIGHT IN THE EASTERN CWA. THE LATEST NAM SOLN...REGENERATES
CONVECTION OVER EASTERN NEBRASKA OVERNIGHT INVOF THE NOSE OF AN
H85 LLJET AND WILL INCLUDE THIS FOR LOCATIONS MAINLY EAST OF
HIGHWAY 183. OVERNIGHT LOWS WILL RANGE FROM THE MIDDLE 50S IN THE
WEST TO THE MIDDLE 60S IN THE EAST. THESE WERE SLIGHTLY HIGHER
THAN GUIDANCE...TO ACCOUNT FOR EXPECTED CLOUDINESS.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 353 AM CDT SUN JUN 29 2014

COOLER AIR FILLS IN BEHIND THE COLD FRONT FOR MONDAY. LINGERING
POST FRONTAL GENERAL THUNDERSTORMS POSSIBLE EARLY MONDAY OVER
EASTERN ZONES. BY AFTERNOON ACTIVITY SHOULD BE WELL TO THE EAST
WITH HIGHS IN THE MID 70S TO THE LOWER 80S...POSSIBLY MID 80S IN
FAR SW NEB. MOSTLY CLEAR SKIES OVERNIGHT WILL HELP TO RADIATE
TEMPS INTO THE LOWER TO MID 50S.

SECONDARY UPPER LEVEL TROUGH AXIS ROTATES AROUND AN ONTARIO LOW
FOR TUESDAY. EXPECT MORE IN THE WAY OF CLOUD COVER AND EVEN SOME
SHOWERS. THE ADDED CLOUDS WILL HELP TO HOLD TEMPS IN THE 70S.
MODELS HAVE CONTINUED A DOWNWARD TREND FOR TEMPS THE LAST 3
RUNS...ALTHOUGH DID NOT DROP AS FAR AS LATEST GUIDANCE CAME IN
WITH. IF SKIES BECOME CLOUDY TO MOSTLY CLOUDY THROUGH MUCH OF THE
DAY...EVEN WITH AN EARLY JULY HIGH SUN ANGLE...TEMPS WILL
STRUGGLE TO WARM TO CURRENT FORECAST.

UPPER LEVEL TROUGH WILL PUSH EAST OF THE AREA FOR THURSDAY.
RETURN SOUTHERLY FLOW WILL BRING WARMER TEMPS AND AN INCREASE IN
MOISTURE. HIGHS BACK INTO THE 80S WITH DEW PTS AROUND 60.
MOISTURE IS LIMITED TO THE LOWER LEVELS. FORECAST IS DRY FOR NOW
WITH MID LEVEL MOISTURE SLOWER TO RETURN.

LL JET THURSDAY WILL HELP TO INCREASE MID TO LOWER LEVEL MOISTURE
AND WILL NEED TO BE MONITORED FOR POSSIBLE ISOLATED THUNDER
INCLUSION ON THE NOSE OF THE JET. BETTER SHOWERS ARRIVES FRIDAY
AND INTO THE WEEKEND. RIDGING OVER THE SOUTHERN AND CENTRAL
ROCKIES WILL CAUSE NORTHWEST FLOW TO DEVELOP. NORTHWEST FLOW WILL
RESULT IN A FEW DISTURBANCES RIDING SE ACROSS THE HIGH PLAINS. AS
THE TREND FROM JUNE CONTINUES INTO JULY...WILL NOT TAKE MUCH TO
PRODUCE AT LEAST SOME ISOLATED ACTIVITY. TEMPS WILL ALSO BE ON THE
RISE...WITH UPPER 80S TO LOWER 90S POSSIBLE...ALONG WITH SEASONAL
LOWS IN THE 60S.
