AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
115 PM CDT FRI JUN 20 2014

.UPDATE...
ISSUED AT 114 PM CDT FRI JUN 20 2014

SHOWERS AND THUNDERSTORMS HAVE DIMINISHED TO A FEW
SPRINKLES...HOWEVER THIS IS EXPECTED TO ONLY BE A SHORT TERM.
STALL BOUNDARY CONTINUED TO RESIDE ACROSS THE STATE. EARLY THIS
AFTERNOON EXPECT THE SUN TO COME ON WITH TEMPS TO RISE INTO THE
MID AND UPPER 80S. THIS WILL CAUSE THE CAP TO WEAKEN AND SCT
THUNDERSTORMS ARE EXPECTED TO DEVELOP. DEVELOPMENT IS EXPECT EAST
OF A VTN TO OGA LINE. INSTABILITY INCREASES WITH CAPE VALUES OF A
2K TO 3K J/KG...AND A WEAK WAVE CROSSING THE ROCKIES THIS
AFTERNOON WILL PROVIDE THE NEEDED KICK START TO GET THINGS GOING
AGAIN. EXPECT STORMS TO REDEVELOP AROUND 4 PM CDT.

&&

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 325 AM CDT FRI JUN 20 2014

THE NAM AND RAP SHOW AN AREA OF MIDLEVEL CLOUDS ACROSS ERN COLO THIS
MORNING BECOMING CONVECTIVELY ACTIVE 09Z-12Z THIS MORNING. THE
DISTURBANCE SHOULD MOVE EAST THRU SRN NEB THIS AM PRODUCING A
CLUSTER OF ELEVATED TSTMS. THE RAP INDICATES 750MB CAPE OF AROUND
1000 J/KG SUGGESTING THE POTENTIAL FOR SOME HAIL. THIS ACTIVITY
DISSIPATES LATE THIS MORNING TO BE FOLLOWED BY A SECOND AREA OF TSTM
DEVELOPMENT FROM ROUGHLY KIML NORTHEAST THROUGH KONL THIS AFTN WITH
THE BETTER RAIN CHANCES FROM HAYES CENTER NORTHEAST THROUGH KONL.

BUFKIT SUGGESTS A WEAK MULTICELL ENVIRONMENT GIVEN THE WEAK SHEAR
AROUND 25 KT. MLCAPE THOUGH AROUND 3000 J/KG IN THE RAP MODEL
SUGGESTS SOME STRONG UPDRAFTS DEVELOPING THIS AFTN NEAR OR SOUTH OF
KOGA AND KLBF. SO SEVERE WEATHER CHANCES CONTINUE ALTHOUGH THE
POTENTIAL FOR LONGER LIVED STORMS WOULD APPEAR LOW.

STORMS WILL LIKELY FIRE FROM SOUTHWEST NEB TO NCNTL NEB THIS
AFTERNOON AND THIS EVENING AND COALESCE INTO CLUSTERS WHICH MOVE OFF
EAST OF THE FCST AREA AROUND 06Z. POPS ARE LIMITED TO 40 PERCENT
GIVEN THE WEAKNESS IN THE WINDS ALOFT AND LOW QPF GENERATED BY THE
MODELS.

HIGHS TODAY RISE INTO THE 80S AND LOWS TONIGHT FALL INTO THE 50S TO
LOWER 60S.

.LONG TERM...(SATURDAY THROUGH THURSDAY)
ISSUED AT 325 AM CDT FRI JUN 20 2014

MOIST...WARM AND UNSTABLE CONDITIONS WILL CONTINUE ACROSS ALL OF
WESTERN AND NORTH CENTRAL NEBRASKA SATURDAY. MODELS ALL AGREE THAT
A WARM FRONT WILL BE LOCATED IN AN EAST TO WEST FASHION...BUT
DISAGREE ON THE LOCATION. REGARDLESS...IT APPEARS THAT SCATTERED
TSTMS WILL INITIATE ACROSS THE HIGH PLAINS IN MOIST UPSLOPE
REGIME. THESE WILL LIKELY BEGIN AS SUPERCELLS WITH BULK SHEAR NEAR
40 KTS. BUFKIT DATA FROM VARIOUS LOCATIONS ACROSS THE PLAINS
SUGGESTS RIGHT TURNING SUPERCELLS THE DOMINATE STORM MODE AT
FIRST...THEN CONGEAL INTO ONE OR MORE CLUSTERS SATURDAY NIGHT AS
SOUTHERLY LOW LEVEL JET INCREASES. THE WARM FRONT LOCATION WILL
HAVE TO BE MONITORED...AS WINDS WILL BE BACKED MORE TO THE EAST ON
THE NORTH SIDE OF THE BOUNDARY...WHICH WILL ENHANCE LOW LEVEL SHEAR
AND POSSIBLE TORNADO DEVELOPMENT.

SUNDAY A SHORTWAVE DISTURBANCE WILL TRACK ACROSS THE NORTHERN
ROCKIES AND TOWARD THE NORTHERN PLAINS. A SURFACE LOW WILL DEEPEN
ACROSS EASTERN COLORADO IN RESPONSE...WITH MOIST EAST TO NORTHEAST
WINDS ACROSS MOST OF WESTERN AND NORTH CENTRAL NEBRASKA TO THE
NORTH OF THE LOW. STORM DEVELOPMENT WILL BE AIDED BY THE SHORTWAVE
DISTURBANCE ACROSS THE PANHANDLE SUNDAY AFTERNOON...WITH STORMS
LIKELY MERGING INTO AN MCS AS THEY TRACK EAST SOUTHEAST ACROSS
NEBRASKA SUNDAY EVENING. LOCALLY HEAVY RAIN COULD MATERIALIZE AND
POTENTIAL WILL HAVE TO BE MONITORED.

MONDAY INTO TUESDAY...SOMEWHAT COOLER AND DRIER BEHIND THE
SHORTWAVE DISTURBANCE. BY MIDWEEK...RICH GULF MOISTURE RETURNS.
MODELS INDICATING DEW POINTS IN THE UPPER 60S TO NEAR 70 FOR MUCH
OF THE FORECAST AREA BY WEEKS END. THATS WHEN TSTM CHANCES MAY
INCREASE ONCE AGAIN...AS UPPER LEVEL TROUGHING DEVELOPS INTO THE
PACIFIC NORTHWEST.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON)
ISSUED AT 114 PM CDT FRI JUN 20 2014

SHOWERS WILL EXIT THE KLBF AREA OVER THE NEXT HOUR...WITH THE SUN
COMING OUT. AFTER A BRIEF BREAK IN ACTIVITY...STORMS ARE EXPECTED
TO REDEVELOP LATER THIS AFTERNOON INTO THE EVENING HOURS ACROSS
SOUTHWEST INTO N CENTRAL NEB. ACTIVITY HAS THE CHANCE TO IMPACT
KLBF...ALTHOUGH LESS CONFIDENCE IN ACTIVITY TO IMPACT KVTN. DID
INCLUDE A SOME TS IN THE KLBF TAF...HOWEVER WATCH FOR AMENDMENTS
