AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
858 PM CDT TUE MAY 27 2014

.SYNOPSIS...
ISSUED AT 319 PM CDT TUE MAY 27 2014

UPPER CLOSED LOW OVER ARKALATEX THIS AFTERNOON. BROAD RIDGING INTO
CENTRAL CANADA WITH CLOSED LOW OVER PACIFIC NORTHWEST. AT 19Z WATER
VAPOR IMAGERY SHOWED A DEEP UPPER LEVEL LOW OVER SOUTH CENTRAL
OKLAHOMA AND NORTH CENTRAL TEXAS...WITH A TIGHT CIRCULATION
INDICATED IN THE VISIBLE SATELLITE AS WELL. RIDGING BUILT OVER THE
NORTHERN AND CENTRAL PLAINS...AS THE RIDGE AXIS WAS ORIENTED FROM
THE DESERT SOUTHWEST INTO WESTERN NEBRASKA AND SOUTH DAKOTA. THE
EAST HALF OF THE COUNTRY WAS LITTERED WITH SHOWER AND THUNDERSTORM
ACTIVITY WHILE THE WESTERN HALF OF THE COUNTRY WAS GENERALLY DRY.
AT THE SURFACE...TEMPERATURES HAD RISEN INTO THE 80S IN MOST
LOCATIONS...WITH SCATTERED CUMULUS SEEN OVER MUCH OF THE AREA.
THERE WAS A COLD FRONT LOCATED FROM NORTHEAST SOUTH DAKOTA INTO
THE NORTHWEST NEBRASKA PANHANDLE...WITH SLIGHTLY COOLER
TEMPERATURES BEHIND THE FRONT IN THE 70S.

&&

.UPDATE...
ISSUED AT 859 PM CDT TUE MAY 27 2014

CONTINUING TO ADJUST PRECIP CHANCES ACROSS THE AREA AS WEAK PV
ANOMALY MOVES EWD ACROSS SD WHICH IS THE MAIN DRIVER FOR THE
CONVECTIVE DEVELOPMENT INITIALLY...HOWEVER OUTFLOW CONTINUES TO
DEVELOP NEW CONVECTION AS IT MOVES SWD. HRRR SEEMS TO HAVE A GOOD
HANDLE ON THIS AND BRINGS THE ISOLATED TSRA INTO THE NORTH CENTRAL
ZONES THROUGH 08Z OR SO. NEW DEVELOPMENT CONTINUES TO BE MAINLY
MULTICELL WITH BRIEF UPDRAFT ENHANCEMENTS TO NEAR SVR LEVELS
BEFORE COLLAPSING. HAVE INCREASED CHCS ACROSS THE NC ZONES INTO
THE EARLY MORNING HOURS. REST OF FCST REMAINS UNCHANGED.

UPDATE ISSUED AT 652 PM CDT TUE MAY 27 2014

ADJUSTED GRIDDED FORECAST POPS SLIGHTLY TO MORE CLOSELY MATCH
CURRENT TRENDS...BUT WORDING REMAINED THE SAME. ISOLATED TSRA
DRIFTING SLOWLY SOUTH AND TYPICAL OF PULSE TYPE STORMS. STORMS
IN SD HAVE EXPANDED SOUTHWARD ALONG OUTFLOW BOUNDRY AND MOVING
SEWD. WRN FRINGE OF THIS COLLIDED WITH ANOTHER BOUNDRY JUST EAST
OF BLACK HILLS RECENTLY TO PRODUCE ADDITIONAL STORMS. WILL BE
MONITORING THESE TRENDS AS CURRENT FORECAST DOES NOT BRING THESE
INTO THE FCST AREA TONIGHT DUE TO LACK OF LLJ TO PRODUCE LIFTING
ALONG OUTFLOW. HOWEVER WILL HAVE TO WATCH FOR ADDITIONAL
DEVELOPMENT. OTHERWISE REMAINDER OF FCST REMAINS THE SAME.

&&

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 319 PM CDT TUE MAY 27 2014

ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE INTO
THE EARLY EVENING HOURS. SURFACE CAPE AS OF 19Z RANGED FROM 500J/KG
TO 2500J/KG ACROSS THE FORECAST AREA WITH THE HIGHER VALUES UP NEAR
AND BEHIND THE COLD FRONT. MOISTURE IN THE MID LEVELS IS LIMITED AND
ALTHOUGH HAVE THE INSTABILITY NOT EXPECTING WIDESPREAD COVERAGE OF
ACTIVITY THROUGH EARLY EVENING OVER MUCH OF THE AREA. MAY GET A FEW
STORMS TO DEVELOP BEHIND THE FRONT...BUT WITH NO LOW LEVEL JET
TONIGHT TO HELP FUEL ANY STORMS EXPECT ACTIVITY TO DIMINISH QUICKLY
AFTER SUNSET. IF THERE ARE ANY STORMS AROUND...THE FLOW IN THE
STEERING LAYER IS LIGHT SO SLOW MOVEMENT IS EXPECTED. AND IN TERMS
OF SEVERE POTENTIAL...WIND SHEAR IS LOW SO DON/T THINK ANY STORMS
LOCALLY WILL BE ABLE TO GET ORGANIZED TO THE POINT OF BEING
SEVERE...AT LEAST NOT IN A SUSTAINED MANNER.

SKIES SHOULD BE MOSTLY CLEAR TONIGHT AND WEDNESDAY AS THE RIDGE
CONTINUES TO BUILD INTO THE PLAINS BRINGING PLENTIFUL DRY AIR WITH
IT. DEWPOINTS IN THE 50S TONIGHT WILL KEEP LOWS MILD...BUT EVEN WITH
LIGHT WINDS...NOT EXPECTING TEMPERATURES TO FALL ENOUGH TO REACH
SATURATION AND DEVELOP FOG. THEN FOR WEDNESDAY...700MB TEMPERATURES
RISE 2-4 DEGREES COMPARED TO THIS AFTERNOON. WITH THE DRY AIR IN
PLACE...LOOKING FOR MIXING TO 700-750MB WHICH WOULD WARM
TEMPERATURES INTO THE UPPER 80S AND POSSIBLY REACH THE 90 DEGREE
MARK IN SOME LOCATIONS. ALTHOUGH LAPSE RATES WILL BE STEEP...WINDS
THROUGH THE MIXED LAYER WILL BE FAIRLY LIGHT SO EVEN WITH INCREASING
WINDS IN THE AFTERNOON FROM THE SOUTH AS HIGH PRESSURE MOVES
EAST...WON/T GET GUSTS TO MUCH OVER 15-20MPH IN THE AFTERNOON.

ALSO...THE FORECAST STAYS DRY FOR WEDNESDAY AS THERE WILL NOT BE
ENOUGH MOISTURE TO CAUSE THE DEVELOPMENT OF SHOWERS OR STORMS.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 319 PM CDT TUE MAY 27 2014

MODELS IN FAIR AGREEMENT IN MID TERM AND THEN DIFFER DRAMATICALLY
THROUGH THE EXTENDED WITH ECMWF DRAWING MUCH COLDER AIR SOUTH INTO
THE NORTHERN PLAINS AFTER FRIDAY WHILE GFS CONTINUES UPWARD TREND
WITH TEMPERATURES RISING INTO THE 90S THROUGH NEXT WEEK. ANOTHER
MAJOR DIFFERENCE BETWEEN THE TWO MODELS IS GFS SENDS REMNANTS OF
AMANDA INTO THE PACIFIC WHILE ECMWF DRAGS REMNANTS THROUGH DESERT
SOUTHWEST. CURRENT FORECAST IS HOLDING TEMPERATURES UP AND WILL
GENERALLY TREND TOWARDS THE GFS FORECAST. STRONG SOUTHERLY FLOW
WEDNESDAY NIGHT OVER WESTERN NEBR SKA UNDER THE UPPER RIDGE WITH
CLEAR SKIES. TEMPERATURES TO BOTTOM OUT AROUND 60. SURFACE TROUGH
ALONG THE FRONT RANGE THURSDAY WITH UPPER TROUGH PUSHING EAST
THUNDERSTORMS EXPECTED OVER THE WESTERN PANHANDLE. HAVE LEFT
NORTHWEST DRY FOR NOW WITH BETTER DYNAMICS TO THE WEST. SIMILAR
CONDITIONS FRIDAY WITH THUNDERSTORMS EXPECTED TO PUSH EAST INTO
THE WESTERN NEBRASKA SANDHILLS LATE AFTERNOON AND THROUGH THE
NIGHT FRIDAY AS A STRONG WAVE MOVES OUT OF THE TROUGH TO THE WEST.
DEW POINTS INTO THE 60S ON SATURDAY...STRONG WARM AIR ADVECTION
AHEAD OF DEEPENING SURFACE LOW AND GOOD SHEER SETUP FOR SEVERE
WEATHER. INCREASED POPS AND SPREAD THEM ACROSS THE FORECAST AREA
THROUGH THE DAY AND INTO SUNDAY WITH SIMILAR PATTERN TO SATURDAY.
TEMPERATURES SOMEWHAT COOLER WITH CLOUDINESS AND PRECIPITATION
WITH NUMEROUS WAVES MOVING OUT OF TROUGH TO THE WEST HAVE CHANCES
OF TRW IN FORECAST THROUGH TUESDAY. HIGH TEMPERATURES IN THE 80S
AND LOWS IN THE 50S AND 60S.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING)
ISSUED AT 652 PM CDT TUE MAY 27 2014

VFR CONDITIONS WILL PREVAIL THROUGH THE FCST PERIOD. ISOLATED TSRA
WILL DRIFT SOUTH THROUGH SUNSET BUT SHOULD DISSIPATE AFTER THAT
WITH A LACK OF SIGNIFICANT FORCING BEYOND DIURNAL TRENDS.
HOWEVER...WILL BE WATCHING CURRENT CONVECTION MOVING SEWD IN
CENTRAL SD AS NEW DEVELOPMENT IS OCCURRING ALONG OUTFLOW GENERATED
EARLIER. IF NEW DEVELOPMENT CONTINUES KVTN MAY NEED SOME ISOLATED
MENTION BEFORE 05Z...BUT HAVE LEFT OUT OF THE FCST AT THIS TIME WITH
LOW CONFIDENCE IN TSRA HOLDING TOGETHER TO THE NEB BORDER. WEAK
TSRA IN NORTHEAST LINCOLN COUNTY SHOULD DISSIPATE AS WELL AFTER SUNSET.
