AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
308 PM CDT MON MAY 27 2013

.SYNOPSIS...
A DEEP UPPER LEVEL LOW WILL MIGRATE EAST THROUGH THE NRN ROCKIES
AND NRN PLAINS THIS WEEK. THIS WILL SEND A STRONG PACIFIC COLD
FRONT THROUGH THE FCST AREA WEDNESDAY. SEVERE WEATHER IS EXPECTED
ALONG AND AHEAD OF THE FRONT TONIGHT...TUESDAY AND PERHAPS WEDNESDAY.

THIS AFTERNOON AND THIS EVENING...A 60KT 300 MB JET MAX WILL MOVE
THROUGH COLO...KS AND SWRN NEB PRODUCING DEEP LEVEL SHEAR
SUFFICIENT FOR SUPERCELL THUNDERSTORMS WITH LARGE HAIL AND WIND
DAMAGE.

&&

.DISCUSSION...
TONIGHT AND TUESDAY...
STRATUS HAS BEEN SLOW TO ERODE ACROSS SOUTHWEST NEB TODAY...AND HAS
LIMITED SURF HEATING...WHICH MAY PLAY INTO SEVERE WEATHER THIS
EVENING. CURRENT TEMPS IN THE UPPER 60S TO LOWER 70S...HOWEVER WHERE
MOSTLY SUNNY SKIES HAVE BEEN THROUGHOUT THE DAY...UPPER 70S. SEVERAL
BOUNDARIES ACROSS THE AREA AND WILL PLAY INTO CONVECTION TODAY. THE
DRY LINE TO THE WEST IS ALREADY SEEING STORMS FIRE AND A SVR WATCH
WAS ISSUED FOR THESE STORMS. ANOTHER ELEVATED AND NEARLY STATIONARY
BOUNDARY IS LOCATED ACROSS THE SANDHILLS INTO NORTH CENTRAL...AND
SOME RADAR RETURNS HAVE PERSISTED HOWEVER LITTLE IF ANY PRECIP HAS
REACHED THE GROUND. AN OUTFLOW BOUNDARY FROM LAST NIGHTS
CONVECTION IS PUSHING SOUTH TOWARDS THE SOUTHERN PLAINS. AS FOR
STORMS THIS EVENING...MOVEMENT WILL BE TO THE EAST OR NORTHEAST
WITH RIGHT MOVERS TO THE ESE. PLENTY OF INSTABILITY WITH CAPE 2K
PLUS...HOWEVER SHEAR IS NOT AS IMPRESSIVE AND WHILE WILL SEE
SUPERCELLS...MAIN THREAT WILL BE HAIL AND WINDS. BETTER SHEAR IS
SE OF THE CWA...WHERE THERE IS THE MODERATE RISK. OVERNIGHT AS LL
JET KICKS IN /TO THE SOUTH/ EXPECT THE SEVERE THREAT TO DIMINISH.
COULD SEE TSTORMS DIMINISH...HOWEVER MODEL CONSENSUS IS FOR THEM
TO SUSTAIN AS THE MOVE ACROSS THE CWA. SOME CONCERN IF THE
MODERATE RISK AREA GETS REALLY GOING...OUR AREA MAY GET CUT OFF.
WILL NEED TO WATCH.

LATE TONIGHT INTO TOMORROW MORNING CONVECTION WILL PUSH EAST OF THE
CWA...WITH BL MOISTURE REMAINING HIGH. FOG AND STRATUS LOOK LIKELY
AND ALREADY INCLUDED IN FORECAST. AS WAS TODAY...BURN OFF IS
QUESTIONABLE AND COULD DEPEND ON LEFT OVER BOUNDARIES. THIS COULD
LIMIT HEATING...HOWEVER FORECAST WILL BE A BLEND OF CLIMO AND
GUIDANCE WHICH DOES BRING OUT THE SUN AND WARMS TEMPS INTO 80S. NEXT
FRONTAL SYSTEM WILL PUSH INTO THE NW CWA BY AFTERNOON AND WILL BE
FOCUS FOR ANOTHER ROUND OF STORMS.

TUESDAY NIGHT THROUGH THURSDAY...
TSTMS SHOULD DEVELOP IN THE EVENING HOURS TUESDAY AND MODEL
CONSENSUS SUGGESTS NORTHWEST NEBRASKA WOULD BE MOST FAVORED FOR
STORM DEVELOPMENT. IT LOOKS LIKE A STRONG DISTURBANCE WILL EJECT
THRU THE CNTL HIGH PLAINS AND THE ACTIVITY COULD LAST MOST OF THE
NIGHT ACROSS THE NRN ZONES.

A STRONG PACIFIC COLD FRONT IS EXPECTED TO ACT AS A TRIGGER FOR TSTM
DEVELOPMENT WEDNESDAY AS UPPER LEVEL SUPPORT INCREASES AND FORCES
THE FRONT PART WAY THROUGH THE FCST AREA. STRONG HEIGHT FALLS OCCUR
AS THE FRONT MOVES THROUGH AND MOISTURE WILL CONTINUE IN PLACE AHEAD
OF THE FRONT. HIGHEST POPS ARE NORTH AND EAST WHERE EITHER THE CAP
IS WEAKEST OR MOISTURE THE DEEPEST. THE COLD FRONT SHOULD MAKE
SUFFICIENT PROGRESS TO KEEP HIGHS NEAR 70 IN THE NORTHWEST WITH 70S
TO LOWER 80S SOUTH AND EAST.

THE FRONT AND ADDITIONAL DYNAMICS OPERATE WEDNESDAY NIGHT WHICH
SHOULD DRIVE THE FRONT COMPLETELY THROUGH THE FCST AREA WITH MUCH
DRIER AND COOLER AIR MOVING IN BEHIND THE FRONT THURSDAY. ALL OF THE MODELS
ARE CLOSING OFF A 700 MB LOW ACROSS THE NRN PLAINS EXCEPT FOR THE
GFS WHICH CLOSES OFF ACROSS NRN NEB. GIVEN THE HISTORY OF THIS
PATTERN PRODUCING LOCALLY HEAVY RAINFALL AND K INDICES NEAR OR ABOVE
40C...LOCALLY HEAVY RAINFALL IS EXPECTED IN ADDITION TO THE SEVERE
WEATHER THREAT OUTLINED BY THE SPC.

ALTHOUGH DRY IS MOVING IN THURSDAY...THE 500 MB COLD POOL...NEAR
-15C SHOULD BE SUFFICIENT FOR A CHANCE OF SHOWERS AND
THUNDERSTORMS...MAINLY NORTH AND EAST.

THURSDAY NIGHT THROUGH TUESDAY MORNING...
COLD AIR ALOFT WILL CONTINUE TO SUPPORT DIURNALLY DRIVEN SHOWERS AND
THUNDERSTORMS THROUGH SATURDAY...MAINLY ACROSS NRN NEB. BY SATURDAY
NIGHT AND BEYOND...THE COLD POOL WILL BE EAST OF THE FCST AREA WITH
DRY AND STABLE CONDITIONS. THUS THE FCST IS DRY SATURDAY THROUGH
TUESDAY MORNING.

SOME VERY COOL AIR WILL BE MOVING IN ALOFT AND HIGHS SATURDAY...THE
COOLEST DAY... MOSTLY IN THE 60S WITH LOWS SUNDAY MORNING IN THE
40S. H700 MB TEMPS ARE -2C TO 0C AND H850 MB TEMPS ARE IN THE SINGLE
DIGITS DURING THIS TIME.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON)
ISSUED AT 105 PM CDT MON MAY 27 2013

LOW STRATUS IS SLOWLY ERODING ACROSS SW NEB...AND WILL CONTINUE
TO LIFT THROUGH THE AFTERNOON HOURS. MEANWHILE A SHORTWAVE WILL BE
THE FOCUS FOR THUNDERSTORMS TO MOVE ACROSS THE AREA LATER THIS
AFTERNOON INTO THE OVERNIGHT HOURS. BETTER MOISTURE/LIFT ACROSS
SOUTHERN NEBRASKA AND HAVE INCLUDED STRONGER WORDING FOR
THUNDERSTORMS IN KLBF TAF. LESS CONFIDENCE OF IMPACT AT KVTN AND
CONTINUED THE VICINITY WORDING. LATE TONIGHT THE RICH BOUNDARY
LAYER MOISTURE SHOULD RESULT IN REDEVELOPMENT OF THE LOW
FOG/STRATUS...WHICH IS IN AGREEMENT BY MOST MODELS/GUIDANCE. ONLY
HICCUP COULD BE EFFECTS FROM CONVECTION...HOWEVER HAVE FOLLOWED
GUIDANCE AND INCLUDED IFR CONDITIONS AT BOTH KLBF AND KVTN FOR THE
EARLY TUESDAY MORNING HOURS.

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