AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
616 PM CDT SAT JUL 2 2011

.AVIATION...00Z TAF. SHOWERS AND A FEW THUNDERSTORMS CONTINUE TO
MOVE ACROSS THE REGION LATE THIS AFTERNOON. MOST OF THE ACTIVITY
HAS BEEN GENERALLY ALONG AND NORTH OF I-80...AND IT APPEARS TO BE
TIED TO A H5 VORTICITY CENTER THAT HAS BEEN CAPTURED BY THE LATEST
RUC13. THE H5 VORT MAX WILL CONTINUE TO MOVE EAST OVER THE NEXT
FEW HOURS...AND SHOULD TAKE MOST OF THE CONVECTIVE ACTIVITY WITH
IT. UNTIL IT EXITS...THERE COULD BE A FEW SHOWERS OR EVEN AN
ISOLATED THUNDERSTORM AT KGRI...AND WILL COVER THAT WITH A BRIEF
TEMPO GROUP FOR MAINLY SHOWERS. A MOSAIC OF REGIONAL RADARS SHOWS
ADDITIONAL CONVECTIVE ACTIVITY ACROSS PARTS OF EASTERN WYOMING AND
EASTERN COLORADO. THE 02.18Z NAM AND LATEST HRRR SUGGEST THAT THE
STORMS FROM OUT WEST WILL MOVE EAST TONIGHT...AND COULD EVENTUALLY
APPROACH KGRI OVERNIGHT. THERE ARE ENOUGH SIGNS THAT THIS ACTIVITY
COULD MAKE IT TO KGRI TO PUT IN A PROB30 GROUP FOR THUNDERSTORMS
AROUND 09Z THAT WILL CONTINUE UNTIL 15Z. OUTSIDE OF THE CONCERNS
FOR CONVECTION...ANOTHER POTENTIAL ISSUE IS MVFR CEILINGS MAY TRY
TO DEVELOP LATE TONIGHT AND INTO SUNDAY. THE 02.18Z NAM HINTS AT
THIS POSSIBILITY BY INCREASING H9 MOISTURE EARLY SUNDAY
MORNING...THOUGH BUFR SOUNDINGS SEEM TO SHOW MORE OF A SCATTERED
LOOK TO THE CLOUD COVER. WILL GO WITH SCATTERED CLOUDS AROUND 2KFT
FOR NOW...BUT ITS SOMETHING THAT MAY NEED TO BE ADJUSTED TO A
CEILING. WINDS WILL GENERALLY BE AROUND 10 KTS OR LESS AND FROM
THE EAST TO SOUTHEAST IN DIRECTION MOST OF THE PERIOD.

&&

.PREV DISCUSSION... /ISSUED 431 PM CDT SAT JUL 2 2011/

SHORT TERM...THROUGH SUNDAY NIGHT. PRIMARY CONCERN IS
THUNDERSTORM CHANCES THROUGH SUNDAY...AND WILL ADMIT OFF THE TOP
THAT CONFIDENCE IN THE DETAILS IS RATHER LOW.

STARTING OFF LATE THIS AFTERNOON...THINGS HAVEN/T NECESSARILY
TURNED OUT QUITE AS EXPECTED. A STUBBORN...FAIRLY PERSISTENT AREA
OF ELEVATED CONVECTION/MAINLY SHOWERS WITH EMBEDDED
THUNDER/CONTINUES BUBBLING ACROSS MAINLY THE WESTERN HALF OF THE
NEB CWA...WITH MORE ISOLATED SHOWER ACTIVITY ACROSS THE EAST. THE
WIDESPREAD CLOUD COVER FROM THIS ACTIVITY HAS HELD DOWN
TEMPERATURES TO AT LEAST SOME DEGREE IN MOST NEB COUNTIES WITH 70S
TO LOW 80S...WHILE MOSTLY SUNNY SKIES IN KS HAVE ALLOWED READINGS
TO REACH THE LOWER 90S. 20Z OBJECTIVE SFC ANALYSIS DEPICTS A BROAD
1020MB HIGH CENTERED ACROSS CENTRAL NEB...TO THE NORTHEAST OF A
WEAK 1012MB LOW IN SOUTHEAST COLORADO. ALTHOUGH NOT DEFINED
TREMENDOUSLY WELL...A NEARLY STATIONARY EAST-WEST FRONT EXTENDS
EAST FROM THE COLORADO LOW THROUGH CENTRAL KANSAS. ALOFT...WATER
VAPOR IMAGERY AND SHORT TERM MODEL DATA DEPICTS QUASI-ZONAL FLOW
ACROSS THE REGION...TO THE NORTH OF A BROAD SUBTROPICAL RIDGE
DOMINATING ROUGHLY THE SOUTHERN HALF OF THE CONUS.

AS STATED OFF THE TOP...CONFIDENCE IN THE CONVECTIVE DETAILS
DURING THE NEXT 24 HOURS IS LESS THAN IDEAL WITH VARIABLE
SOLUTIONS IN THE MODEL WORLD. AS A RESULT...HAVE RELIED MORE
HEAVILY ON ENSEMBLE DATA SUCH AS THE SREF...ALONG WITH EXPLICIT
HIGHER RESOLUTION MODELS SUCH AS THE 12Z 4KM WRF-NMM AND THE
LATEST HRRR. THROUGH MIDNIGHT OR SO...EXPECT THE ONGOING ELEVATED
CONVECTION ACROSS THE WEST TO CONTINUE DEVELOPING...AND GRADUALLY
SHIFTING A BIT NORTH AND EAST WITH TIME AS IT SEEMS TIED PRETTY
WELL TO THETA-E ADVECTION AROUND H7. ALTHOUGH A FEW STORM CORES ON
THE WESTERN FRINGES OF THIS ACTIVITY HAVE SHOWN SOME SIGNS OF
RECENT STRENGTHENING ACROSS THE LBF CWA...NOT EXPECTING A BIG
SEVERE WEATHER THREAT WITH ANYTHING ACROSS THE LOCAL AREA...GIVEN
DEEP LAYER SHEAR ONLY AROUND 30KT...AND FAIRLY UNIMPRESSIVE MID
LEVEL LAPSE RATES AROUND 7C/KM. CERTAINLY CANNOT RULE OUT A NICKEL
HAILER THROUGH DARK HOWEVER MAINLY IN THE WEST. ALTHOUGH NOT AS
LIKELY...SOME ISOLATED CONVECTION COULD SNEAK NORTH INTO KS ZONES
THIS EVENING AS WELL AS THE EAST-WEST FRONT AND ASSOCIATED
INSTABILITY NOSES NORTHWARD...WITH CONSIDERABLY LESS LOW LEVEL
INHIBITION NOTED IN KS VERSUS NEBRASKA.

AFTER DARK TONIGHT...THERE ARE REALLY TWO MECHANISMS FOR POSSIBLE
CONVECTION. FOR ONE THING...THE NEXT IN A PARADE OF LOW AMPLITUDE
SHORTWAVES IS ALREADY KICKING OFF CONVECTION ACROSS EASTERN
WYOMING...AND THIS COULD EVENTUALLY EVOLVE INTO AT LEAST A SEMI-
ORGANIZED MCS...AND ROLL INTO THE CWA FROM THE WEST MAINLY AFTER
MIDNIGHT. SECONDLY...ACROSS THE LOCAL REA THERE IS A STRONG SIGNAL
FOR A STRENGTHENING LOW LEVEL JET AFTER DARK...ALONG WITH
ASSOCIATED THETA-E ADVECTION EVIDENT AT H85. GIVEN WEAK CAPPING
FOR ELEVATED PARCELS...THUS ANTICIPATE AN INCREASE IN EVENING AND
OVERNIGHT CONVECTION WITH THE LOW LEVEL JET AS WELL. ONE WAY OR
ANOTHER...A GOOD CHUNK OF THE CWA SHOULD SEE RAIN TONIGHT...BUT
DUE TO LACK OF CONFIDENCE IN EXACTLY WHERE AM ONLY PLAYING 60 POPS
ACROSS THE NORTHERN HALF AND 40S-50S IN THE SOUTH FOR NOW. STAY
TUNED FOR UPDATES LATER THIS EVENING AS THE PICTURE HOPEFULLY
BECOMES A BIT CLEARER. AGAIN...NOT EXPECTING WIDESPREAD SEVERE
WEATHER OVERNIGHT...BUT WITH 1000-2000 J/KG MUCAPE AND UP TO 35KT
OF DEEP LAYER SHEAR...ISOLATED LOWER END SEVERE CERTAINLY
POSSIBLE...ESPECIALLY ACROSS THE WESTERN HALF OF NEB ZONES.

HEADING INTO THE DAYTIME HOURS SUNDAY...THE MAIN QUESTION IS HOW
MUCH CONVECTION WILL BE ONGOING. PER THE ORIENTATION OF THE LOW
LEVEL JET...THE BEST MOISTURE TRANSPORT SHOULD BE INTO THE EASTERN
HALF OF THE CWA IN THE MORNING...AND HAVE FOCUSED HIGHEST POPS
HERE BUT ONLY UP TO 50S FOR NOW. MID SHIFT MAY VERY WELL HAVE TO
BOOST THESE MORNING POPS INTO LIKELY TERRITORY...WITH POTENTIAL
FOR AT LEAST A FEW STRONG STORMS WITH NICKEL SIZED HAIL
CONTINUING. FOR SUNDAY AFTERNOON...RIDGING BUILDS NORTHWARD A
BIT...WITH NO OBVIOUS MID LEVEL WAVES IN SIGHT. HOWEVER CAPPING IS
NOT OVERLY STRONG AND IT WON/T TAKE MUCH TO SET OFF ISOLATED
CONVECTION ESPECIALLY ACROSS THE SOUTHEAST HALF OF THE CWA...SO
WILL CONTINUE CARRYING LOW END POPS. AGAIN...A FEW STRONG STORMS
CANNOT BE RULED OUT...BUT NOT WIDESPREAD SEVERE.

FOR SUNDAY NIGHT...WILL SOMEWHAT HESITANTLY CONTINUE A DRY
FORECAST...AS LARGE SCALE FORCING IS WEAKER WITH THE RIDGE
BUILDING IN FROM THE SOUTHWEST...WHICH SHOULD ALSO SHUNT THE MAIN
CORRIDOR OF LOW-MID LEVEL THETA-E ADVECTION OFF TO THE EAST. WOULD
NOT BE SHOCKED THOUGH IF AT LEAST ISOLATED STORMS AFFECT THE CWA
AT LEAST SUNDAY EVENING THOUGH...AND WILL DEFER TO FUTURE SHIFTS
TO SEE IF SLIGHT POPS ARE WARRANTED. ALSO LATE SUNDAY
NIGHT...LIGHT...MOIST SOUTHEASTERLY BREEZES COULD RESULT IN AT
LEAST LIGHT FOG FORMATION...AND HAVE INTRODUCED PATCHY FOG WORDING
AFTER MIDNIGHT.

TEMPERATURE WISE...LOWERED HIGHS A FEW DEGREES FOR SUNDAY MOST
AREAS MAINLY DUE TO QUESTIONS ABOUT THE DEGREE OF CLOUD COVER AND
POSSIBLE DAYTIME CONVECTION. IN GENERAL...EXPECTING MID TO UPPER
80S ACROSS THE NORTHEAST 1/2 OF THE CWA...AND UPPER 80S TO MID 90S
SOUTHWEST. NO BIG CHANGES TO LOWS TONIGHT AND SUNDAY
NIGHT...RANGING FROM MID 60S TO AROUND 70 EACH NIGHT.

LONG TERM...MONDAY THROUGH SATURDAY. DRY AND WARM WEATHER IS
EXPECTED FOR THE START OF THE EXTENDED AS AN UPPER LEVEL RIDGE OF
HIGH PRESSURE WILL BE CENTERED OVER THE CENTRAL PLAINS MONDAY
AFTERNOON...RESULTING IN A DRY AND SEASONABLY WARM FOURTH OF JULY
ACROSS THE REGION. THIS WARM AND DRY WEATHER IS EXPECTED TO BE
FAIRLY SHORT LIVED...AS A COLD FRONT IS EXPECTED TO TRACK ACROSS
SOUTH CENTRAL NEBRASKA ON TUESDAY...HELPING TO ERODE THE RIDGE OF
HIGH PRESSURE ALONG WITH BRINGING A CHANCE OF THUNDERSTORMS AND
COOLER TEMPERATURES BY THE AFTERNOON HOURS. WHILE THE ACTUAL
TIMING AND INTENSITY OF THIS FRONT WILL STRONGLY AFFECT
TEMPERATURES TUESDAY AFTERNOON...WITH NEARLY A 10 DEGREE IN
TEMPERATURE GUIDANCE FOR THE AFTERNOON HOURS...SIDED WITH MORE
PROGRESSIVE TIMING OF THIS FRONT AS TRENDED BY LATEST MODELS...AND
HENCE COOLER TEMPERATURES FOR THE ENTIRE FORECAST AREA BY THE
AFTERNOON HOURS.

EXPECT THIS AFOREMENTIONED FRONTAL BOUNDARY TO STALL OVER CENTRAL
KANSAS BY WEDNESDAY MORNING...WITH SEVERAL WEAK UPPER LEVEL
DISTURBANCES EXPECTED TO HELP MAINTAIN PERIODIC CHANCES OF SOME
SHOWERS AND THUNDERSTORMS THROUGH THE END OF THE WORK WEEK. THESE
CHANCES COULD BE PARTICULARLY ENHANCED WITH NOSE OF LOW LEVEL JET
POINTING TOWARDS THE REGION BOTH WEDNESDAY AND FRIDAY
MORNINGS...WITH LITTLE EVIDENCE OF THE UPPER LEVEL RIDGE
STRENGTHENING AND REBUILDING IN CURRENT TIME FRAME OF EXTENDED
FORECAST. THEREFORE...SOME SMALL TO CHANCE POPS INCLUDED ACROSS
PORTIONS OF THE ENTIRE FORECAST AREA THROUGH SATURDAY OF NEXT WEEK.
