AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
700 PM CDT THU JUN 26 2014

.UPDATE...
ISSUED AT 659 PM CDT THU JUN 26 2014

HAVE UPDATED THE EVENING FORECAST TO ADJUST CHANCES FOR
PRECIP...ESPECIALLY ACROSS SOUTHWEST NE. HRRR SUGGESTING A COMPLEX
DEVELOPING ACROSS THE WEST AND MOVING EAST LATER THIS EVENING.
CURRENT RADAR EVOLVING CLOSE TO HRRR PROGS AND THIS SEEMS
PLAUSIBLE. SOME POTENTIAL FOR HIGH WINDS WITH ANY STORMS THAT
DEVELOP. OTHERWISE TEMPS LEFT PRETTY MUCH AS IS.

&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 337 PM CDT THU JUN 26 2014

VERY UNSTABLE CONDITIONS RESIDE ACROSS THE NEBRASKA PANHANDLE INTO
THE EASTERN PLAINS OF COLORADO. ANALYSIS INDICATES SURFACE BASED
CAPES RUNNING IN THE 3000 TO 4500 J/KG RANGE. THIS SEEMS REASONABLE
GIVEN STEEP MID LEVEL LAPSE RATES AND AND DEW POINT TEMPERATURES IN
THE 60S. LITTLE CAPPING INVERSION LEFT AND EXPECT THAT ISOLATED TO
SCATTERED COVERAGE OF THUNDERSTORMS TO DEVELOP LATE THIS AFTERNOON.
BEST FORCING REMAINS WEST OF THE REGION TODAY...SO NOT EXPECTING
WIDESPREAD DEVELOPMENT. NEVERTHELESS ENOUGH SHEAR AND INSTABILITY
SUGGESTS A FEW OF THE STORMS WILL BECOME SEVERE BY LATE THIS
AFTERNOON.

TONIGHT EXPECT A CLUSTER OR TWO OF STORMS TO MOVE EAST INTO WESTERN
KANSAS AND NEBRASKA...AIDED BY SOUTHERLY LOW LEVEL JET OF 35 KTS.
AGAIN BEST LARGE SCALE FORCING TO REMAIN WEST OF THE REGION...SO
WILL KEEP POPS FAIRLY LOW. OTHERWISE A VERY MILD NIGHT...WITH LOWS
IN THE 60S TO NEAR 70 DEGREES DUE TO HIGH AMOUNTS OF
MOISTURE/HUMIDITY.

THERMODYNAMIC ENVIRONMENT IS QUITE FAVORABLE OF THUNDERSTORM
DEVELOPMENT ON FRIDAY. STEEP MID LEVEL LAPSE RATES AND HIGH MOISTURE
CONTENT /DEW POINTS IN THE MID TO UPPER 60S/ SHOULD YIELD MLCAPE IN
EXCESS OF 2500 J/KG. A CAPPING INVERSION SHOULD BE IN PLACE THROUGH
MUCH OF THE MORNING INTO EARLY AFTERNOON AS AN ELEVATED MIXED LAYER
SPREADS EAST ACROSS THE REGION. LARGE SCALE FORCING INCREASES
DRAMATICALLY FRIDAY AFTERNOON JUST AHEAD OF A POTENT SHORTWAVE
DISTURBANCE APPROACHING FROM THE WEST. COOLING ALOFT ALSO SPREADS
INTO THE AREA AFTER NOON WITH THE ARRIVAL OF THE DISTURBANCE. A
SURFACE COLD FRONT EXTENDING FROM NEAR MERRIMAN TO OGALLALA SHOULD
BE THE FOCUS FOR RAPID THUNDERSTORM DEVELOPMENT AROUND 3 OR 4 PM
CENTRAL TIME. AHEAD OF THE FRONT WINDS WILL BE BACKED TO THE
SOUTHEAST...VEERING TO SOUTHWEST ALOFT. INITIAL STORM MODE WILL
LIKELY BE IN THE FORM OF SUPERCELLS...WITH LARGE HAIL THE MAIN
THREAT. RATHER WEAK UPPER LEVEL FLOW SUGGESTS STORMS WILL BE SLOW
MOVING AT FIRST. STORMS SHOULD BECOME MORE NUMEROUS AND FASTER
MOVING AS COLD POOL ALOFT EVOLVES AND STORMS SPREAD EAST FRIDAY
EVENING.

.LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 337 PM CDT THU JUN 26 2014

THUNDERSTORMS SHOULD BE WELL UNDERWAY EARLY FRIDAY EVENING. A
RATHER STRONG UPPER TROUGH WILL MOVE ONTO THE CENTRAL AND
NORTHERN PLAINS CREATING STEEP MID LEVEL LAPSE RATES OF 8 TO 8.5
C/KM. SCATTERED COVERAGE WEST OF HWY 83 EARLY IN THE EVENING
SHOULD QUICKLY CONGEAL INTO A SMALL MCS. WHILE LARGE HAIL AND
LOCALLY HEAVY RAINFALL IS THE PRIMARY CONCERN EARLY EVENING...THIS
SHOULD TRANSITION TO A DAMAGING WIND/LOCALLY HEAVY RAIN THREAT
LATE EVENING/OVERNIGHT.

SATURDAY MORNING SHOULD BE DRY WITH A POTENTIAL FOR THUNDERSTORM
DEVELOPMENT ALONG A MID LEVEL TROUGH AXIS. ANY DEVELOPMENT SHOULD
PUSH EAST OF THE FA FOR DRY CONDITIONS ONCE AGAIN SATURDAY NIGHT.

ON SUNDAY...A CLOSED UPPER LOW WILL TRACK FROM SRN SASKATCHEWAN
INTO SRN MANITOBA AS AN UPPER TROUGH MOVES ACROSS THE NRN AND
CNTRL PLAINS. MID LEVEL LAPSE RATES WILL AGAIN BE STEEP AND AS CAP
WEAKENS...THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG A WEAK COLD
FRONT FROM MINNESOTA INTO NERN AND CENTRAL NEBR. THE ECMWF MODEL
IS THE MOST ROBUST WITH CONVECTIVE DEVELOPMENT AND HAVE INCREASED
POPS SUN AFTN/EVENING TO AS HIGH AS 30 TO 50 PERCENT ACROSS THE
ERN HALF OF FA.

DRY AND PLEASANT MONDAY AND TUESDAY IN THE LOWER 80S UNDER
INFLUENCE OF CANADIAN AIRMASS. A SLIGHT CHANCE FOR SHOWERS AND
THUNDERSTORMS BY WEDNESDAY NIGHT/THURSDAY AS BETTER MOISTURE AND
INSTABILITY RETURN TO THE REGION.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING)
ISSUED AT 659 PM CDT THU JUN 26 2014

DIFFICULT FORECAST ESPECIALLY FOR KLBF SITE THROUGH 09Z OR SO. TSRA
IS DEVELOPING AS PER SHORT RANGE GUIDANCE SUGGESTS AND BASED ON
CURRENT MESOANALYSIS PARAMETERS PROGRESSION EWD THIS EVENING SEEMS
REASONABLE. LLJ IS EXPECTED TO DEVELOP LATE AS WELL WHICH SHOULD
CONTINUE ANY ORGANIZED COMPLEX AS IT MOVES EWD...BUT SHOULD BE
SOUTH OF KVTN. DIFFICULTY LIES IN CIG FORECAST POST TSRA. SHORT RANGE
MODELS AND NAM INDICATING GOOD POTENTIAL FOR IFR CONDITIONS WITH
STRATUS BEHIND THE CONVECTION AND HAVE PUT THIS IN THE FORECAST
THOUGH CONFIDENCE IS LOW BASED ON EVENTUAL EVOLUTION OF TSRA.
BEYOND 12Z...AGAIN LOW CONFIDENCE IN POSSIBILITY OF STRATUS BUT
TSRA DEVELOPMENT IS LIKELY AGAIN BY AFTERNOON AT BOTH KLBF AND
KVTN.

914 PM CDT THU JUN 26 2014 /814 PM MDT THU JUN 26 2014/

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF WESTERN AND
NORTH CENTRAL NEBRASKA.

.DAY ONE...TONIGHT.

A COUPLE AREAS OF THUNDERSTORMS WILL MOVE ACROSS WESTERN AND
NORTH CENTRAL NEBRASKA TONIGHT. THE FIRST IS EXPECTED TO MOVE
ACROSS THE NORTHERN SANDHILLS AND NORTHWEST NEBRASKA. WIDESPREAD
SEVERE WEATHER IS NOT EXPECTED AT THIS TIME WITH THIS COMPLEX...BUT BRIEF
HEAVY RAIN AND GUSTY WINDS WILL STILL BE POSSIBLE.

ANOTHER THUNDERSTORM COMPLEX IS EXPECTED TO TRACK EAST ACROSS
PORTIONS OF SOUTHWEST NEBRASKA TONIGHT. THIS AREA OF THUNDERSTORMS
WILL BE CAPABLE OF PRODUCING HEAVY RAIN ALONG WITH HAIL AND STRONG
WINDS. AN ISOLATED STORM OR TWO MAY BE CAPABLE OF PRODUCING SEVERE
WEATHER...SUCH AS LARGE HAIL AND DAMAGING WINDS.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS MOST OF
WESTERN AND NORTH CENTRAL NEBRASKA FRIDAY. AN UNUSUALLY STRONG LOW
PRESSURE SYSTEM WILL MOVE INTO THE PLAINS DURING THE DAY. AHEAD OF
THIS FEATURE...AN INCREASE OF LOW LEVEL MOISTURE WILL PRODUCE AN
UNSTABLE ATMOSPHERE. AS THE THE SYSTEM AND ASSOCIATED COLD FRONT
MOVE INTO THE AREA BY AFTERNOON...THUNDERSTORMS ARE EXPECTED TO
DEVELOP. SOME OF THE STORMS WILL HAVE THE POTENTIAL TO PRODUCE
LARGE HAIL AND DAMAGING WINDS BY LATE AFTERNOON AND EVENING.
ISOLATED TORNADOES WILL ALSO BE POSSIBLE.

ANOTHER STRONG COLD FRONT IS EXPECTED TO MOVE ACROSS THE AREA
SUNDAY AFTERNOON AND EVENING. THERE IS A POSSIBILITY FOR STRONG TO
SEVERE THUNDERSTORMS WITH THIS FRONT AS WELL...THOUGH IT IS
DIFFICULT AT THIS TIME TO DETERMINE EXACTLY WHERE THE BEST CHANCES
FOR SEVERE WEATHER WILL BE. LATER FORECASTS WILL BETTER DETERMINE
THE RISK FOR ANY SEVERE THUNDERSTORM ACTIVITY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL LIKELY BE NEEDED ACROSS ALL OF WESTERN AND
NORTH CENTRAL NEBRASKA FRIDAY AFTERNOON AND EVENING.
