Area forecast discussion, Jun 10, 6:38 PM CDT, 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
638 PM CDT WED JUN 10 2015

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 325 PM CDT WED JUN 10 2015

NEBULOUS CONVECTIVE SETUP THIS AFTERNOON AS UPPER LEVEL FORCING IS
BROAD AN UNFOCUSED EARLY THIS AFTERNOON. STATIONARY FRONTAL BOUNDARY
HAS REMAINED FURTHER SOUTH THAN EARLIER MODELS HAD SUGGESTED BUT IS
PROGGED TO DRIFT NORTH AS SOUTHERLY WINDS INCREASE IN RESPONSE TO
LARGE SCALE FORCING. CLOUD COVER AND SHRA HAVE LIMITED REALIZED
INSTABILITY SO FAR...THOUGH LOW LEVEL LAPSE RATES HAVE INCREASED
ACROSS EASTERN AREAS. SPC DEEP MOIST CONVERGENCE HAS ALSO INCREASED
IN VCNTY OF THE WESTERN SANDHILLS SO WOULD EXPECT AN INCREASE IN
COVERAGE AND INTENSITY THROUGH THE NEXT 6 HRS.

WHILE SEVERE STORMS ARE A THREAT...ESPECIALLY WINDS ASSOCIATED WITH
CONVECTIVE OUTFLOW...HEAVY RAIN IS AS BIG OF A CONCERN AS PW VALUES
RANGING IN THE 90TH PERCENTILE OR BETTER AND K INDEX VALUES
EXCEEDING 40 ACROSS THE AREA /SPC MESOANALYSIS SHOWING +45 IN LBF
VCNTY/.

MODELS HAVE TRENDED DRIER FOR MUCH OF THE AREA THURSDAY AND HAVE
ADJUSTED GRIDS IN THAT DIRECTION. MUCH BELOW AVE TEMPS HOWEVER.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 325 PM CDT WED JUN 10 2015

FORECAST CHALLENGE WILL BE RAINFALL CHANCES INTO THE WEEKEND THROUGH
TUESDAY. THE MODELS ARE IN GOOD AGREEMENT THURSDAY THROUGH SUNDAY
THEN LESS CONSENSUS SEEN BEYOND. THE UPPER PATTERN TRANSITIONS WHERE
THE CLOSED UPPER LOW OVER THE SOUTHWEST WILL FILL AND BECOME AN
OPEN WAVE BY SATURDAY WHILE LIFTING NORTHEAST. THE PATTERN SHIFT
BRINGS BROAD TOUGHING TO THE WEST WHILE THE UPPER RIDGE BUILDS FROM
THE MIDWEST TO THE EAST COAST THROUGH NEXT TUESDAY.

A COLD FRONT MOVES SOUTH THURSDAY THAT WILL BRING ABOUT BELOW NORMAL
TEMPERATURES FRIDAY THROUGH SUNDAY. THE WEATHER DRIES OUT THURSDAY
NIGHT AS A SHORTWAVE RIDGE BUILDS EAST OVER THE NORTHERN PLAINS
AND THE SURFACE HIGH RIDGES SOUTHWEST INTO THE NORTHWEST SANDHILLS
THROUGH FRIDAY MORNING. THERE IS SOME QUESTION TO JUST HOW MUCH
CLEARING WILL TAKE PLACE...WHERE CLOUD COVERAGE DECREASES ACROSS
THE NORTH FRIDAY MORNING. THE LESS CLOUDS AND LIGHT WINDS WILL
RESULT IN FRIDAY MORNING LOW TEMPERATURES RANGING FROM THE UPPER
40S NORTH TO 50S SOUTH.

ON FRIDAY CLOUDS WILL LINGER ACROSS THE SOUTH THEN DEVELOP NORTH AS
THE FRONT ACROSS KANSAS RETURNS NORTH. THE EVENTUAL FRONTAL POSITION
WILL DETERMINE AREAL CONVECTION POTENTIAL...WHERE SUNDAY THE FRONT
WILL BE THE FOCUS FOR CONVECTION INTO SUNDAY AS THE SHORTWAVE TROUGH
LIFTS NORTHEAST. FOR NOW...THE NORTHWEST APPEARS DRIER AND THE
CHANCE FOR THUNDERSTORMS CONTINUES FOR THE SOUTHWEST AND NORTH
CENTRAL SATURDAY AND SUNDAY. DAYTIME HIGHS WILL BE BELOW NORMAL
FRIDAY THROUGH SUNDAY AND MAINLY IN THE 70S.

MONDAY THE FRONT SLIPS SOUTH HOWEVER EMBEDDED DISTURBANCES WILL
INTERACT WITH THE FRONT BACKED WEST TO THE FRONT RANGE FOR
THUNDERSTORMS EACH DAY THROUGH WEDNESDAY. TEMPERATURES RETURN TO NORMAL OR
SLIGHTLY ABOVE MONDAY AND TUESDAY.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 636 PM CDT WED JUN 10 2015

FOR THE KLBF TERMINAL THROUGH 05Z THIS EVENING...THUNDERSTORMS
WILL BE POSSIBLE WITH WIND GUSTS TO 40 KTS AND HEAVY RAIN. VISBYS
AND CIGS IN THE VICINITY OF TSRAS WILL BE AT 3SM AND 2500 FT AGL
RESPECTIVELY. CIGS WILL FALL TO AROUND 1800 FT AGL
OVERNIGHT...INCREASING TO 5000 FT AGL BY MIDDAY THURSDAY. FOR THE
KVTN TERMINAL...THERE IS A THREAT FOR THUNDERSTORMS THIS
EVENING...HOWEVER VISBYS WILL BE AOA 6SM AS PRECIPITATION IS
EXPECTED TO BE LIGHT IN INTENSITY. CIGS WILL FALL FROM 3000 TO
5000 FT AGL THIS EVENING...TO AROUND 1500 FT AGL OVERNIGHT AND
INTO THURSDAY MORNING. CIGS WILL CLIMB TO 2500 FT AGL THURSDAY
AFTERNOON.

.HYDROLOGY...
ISSUED AT 325 PM CDT WED JUN 10 2015

HIGH FLOWS WILL CONTINUE ON THE SOUTH PLATTE, NORTH PLATTE AND
PLATTE RIVERS AS THE COMBINATION OF SNOWMELT IN THE UPPER BASINS
AND HEAVY RAINFALL CREATE INCREASED FLOWS.
