AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
340 PM CDT SAT AUG 14 2010

.DISCUSSION...

DAYS 1-2...

CONSIDERABLE UNCERTAINTY EXISTS REGARDING EVOLUTION OF THUNDERSTORMS
AND THE INTERACTION OF MESOSCALE BOUNDARIES THROUGH MONDAY. IN THE
ABSENCE OF WELL DEFINED SYNOPTIC SCALE FEATURES MOVING THROUGH
WESTERN KANSAS AND PERSISTENCE OF A MOIST, LARGELY UNCAPPED
ENVIRONMENT, CONFIDENCE IN THE LOCATION AND INTENSITY OF
THUNDERSTORM DEVELOPMENT IS LOW. THE GREATEST CHALLENGES FOR THE
SUNDAY-MONDAY PERIOD ARE THE FOLLOWING: 1) THUNDERSTORM TIMING AND
COVERAGE; 2) EXTENT OF CLOUD COVER; AND 3) TEMPERATURES.

THE NUMERICAL MODELS ARE SIMILAR IN HANDLING THE SYNOPTIC SCALE
FEATURES, AND THE 12Z ECMWF SOLULTION IS VERY CLOSE TO THE GFS
THROUGH MONDAY, ALTHOUGH THE GFS IS SLIGHTLY FARTHER SOUTH THAN THE
ECMWF WITH THE CONVECTIVE CLUSTER MONDAY NIGHT. THE MODELS HAVE
TENDED TO BE TOO FAR NORTH WITH THUNDERSTORM CLUSTERS THIS SUMMER,
AND THE MORE SOUTHERN TRACK OF THE GFS APPEARS TO BE MORE LIKELY.
THE GFS LARGELY WAS USED FOR GRID MODIFICATIONS.

THE WEAK UPPER LEVEL COLD POOL MOVING THROUGH CENTRAL KANSAS THIS
AFTERNOON HAS SUPPORTED AN AREA OF PERSISTENT HIGH BASED SHOWERS AND
A FEW THUNDERSHOWERS THAT EXTENDED FROM NEAR HAYS TO JUST EAST OF
DODGE CITY EARLY THIS AFTERNOON. THE FRONT THAT MOVED THROUGH
WESTERN KANSAS FRIDAY AFTERNOON HAS RETREATED AS A WARM FRONT
AND...BASED ON RADAR DATA AND SURFACE OBSERVATIONS...EXTENDED NEAR A
LINE FROM FRIEND TO PRATT EARLY THIS AFTERNOON. WITH CONTINUED
SURFACE HEATING AND EROSION OF THE MID LEVEL WARM POOL BY ELEVATED
SHOWERS, SURFACE BASED THUNDERSTORMS PROBABLY WILL DEVELOP BY LATE
AFTERNOON NORTH OF DODGE CITY. SUFFICIENT DEEP LAYER SHEAR EXISTS TO
SUPPORT SOME ORGANIZATION OF THUNDERSTORM ACTIVITY, AND A FEW
THUNDERSTORMS LIKELY WILL PRODUCE HAIL LARGER THAN QUARTERS AND
GUSTY DOWNBURST WINDS. THESE THUNDERSTORMS LIKELY WILL MOVE INTO
CENTRAL KANSAS THIS EVENING.

AN UPPER LEVEL TROUGH WILL MOVE ACROSS THE DAKOTAS TO THE GREAT
LAKES BY SUNDAY MORNING, AND A REINFORCING SURGE OF COLD AIR WILL
MOVE ACROSS KANSAS TONIGHT. ENHANCED UPSLOPE FLOW AND MOISTURE
POOLING BEHIND THE FRONT WILL SUPPORT DEVELOPMENT OF THUNDERSTORMS
IN EASTERN COLORADO THAT SHOULD MOVE INTO WESTERN KANSAS BY MIDNIGHT
AND PROPAGATE INTO CENTRAL KANSAS BY SUNRISE. AS THE UPPER LEVEL
TROUGH RIPPLES ACROSS THE NORTHERN UNITED STATES TONIGHT AND SUNDAY,
KANSAS WILL BE INFLUENCED BY UPPER LEVEL DIVERGENCE IN THE ENTRANCE
REGION OF THE JET STREAK. UPWARD VERTICAL MOTION SHOULD CONTINUE
THROUGH THE DAY SUNDAY, AND WIDESPREAD MID LEVEL CLOUDINESS WITH
SCATTERED SHOWERS AND THUNDERSHOWERS SHOULD PERSIST.

THE SURFACE FRONT WILL EXTEND FROM NORTHERN ARKANSAS ACROSS SOUTHERN
OKLAHOMA INTO SOUTHEAST COLORADO SUNDAY EVENING, AND MOST OF THE
STRONGER THUNDERSTORMS WILL BE WELL TO THE SOUTH OF SOUTHWEST KANSAS
SUNDAY AFTERNOON. UPSLOPE FLOW OF MOIST AIR INTO EASTERN COLORADO
SHOULD SUPPORT DEVELOPMENT OF A THUNDERSTORM CLUSTER LATE SUNDAY,
AND THE THUNDERSTORM CLUSTER LIKELY WILL MOVE ACROSS THE SOUTHWEST
CORNER OF KANSAS SUNDAY NIGHT. CHANCES FOR THUNDERSTORMS WILL BE
LESS ON MONDAY, ALTHOUGH ANOTHER ROUND OF THUNDERSTORMS MAY MOVE OFF
THE ROCKIES INTO WESTERN KANSAS MONDAY EVENING AS THE UPPER LEVEL
CYCLONE EVIDENT ON SATELLITE IMAGERY NEAR 128W APPROACHES THE
CENTRAL PLAINS. THE MOST WIDESPREAD THUNDERSTORMS PROBABLY WILL BE
ACROSS THE NORTHERN HALF OF KANSAS MONDAY NIGHT.

DAYS 3-7...

A WET REGIME WILL REMAIN IN PLACE FOR SOUTHWEST KANSAS MONDAY NIGHT
INTO EARLY ON TUESDAY AS THE MODELS ARE CONSISTENT IN DISPLAYING A
FRONT STALLED ALONG THE SOUTHERN EDGE OF THE WESTERLIES FROM
NORTHERN OKLAHOMA INTO CENTRAL COLORADO.  THIS WILL ALLOW A VERY
MOIST EAST/SOUTHEAST WIND NORTH OF THE FRONT WITH DEWPOINTS IN THE
MID 60S TO NEAR 70 ABLE TO PENETRATE THE FRONT RANGE REGION OF
COLORADO.  SYNOPTICALLY, THIS IS A CLASSIC SETUP FOR CONVECTIVE
DEVELOPMENT ACROSS EASTERN COLORADO DURING THE EARLY TO MID
AFTERNOON AND SUBSEQUENT TRACKING OF AN MCS ACROSS WESTERN KANSAS
DURING THE EVENING TO OVERNIGHT HOURS.  MUCAPE VALUES ARE PROGGED TO
REMAIN AROUND A 1000 J/KG INTO THE EARLY OVERNIGHT HOURS AND WITH
DEEP LAYER SHEAR OVER 40 KNOTS, I SUSPECT A FEW STRONG TO SEVERE
STORMS WILL BE POSSIBLE.

TUESDAY IS THEN SHAPING UP TO BE A TRANSITION PERIOD AS ANY
LINGERING MORNING CONVECTION FROM THE AFOREMENTIONED MCS, WILL SLIDE
EAST OF THE FORECAST AREA BY LATE MORNING WHILE THE UPPER RIDGE
BEGINS TO AMPLIFY OVER THE SOUTHERN TO CENTRAL ROCKIES.  THIS WILL
ALLOW SUBSIDENCE TO DOMINATE THE CENTRAL HIGH PLAINS BY AFTERNOON
WITH DRY CONDITIONS PREVAILING INTO THE EVENING HOURS.  HIGH
TEMPERATURES WILL BE A TAD TRICKY ON TUESDAY AS SOILS ARE EXPECTED
TO BE WET AND WITH THE AIRMASS HAVING BEEN WORKED OVER BY OVERNIGHT
CONVECTION, WILL AIM FOR HIGHS IN THE MID 80S TO AROUND 90.

HEAT WILL THEN RETURN TO THE CENTRAL HIGH PLAINS FOR WEDNESDAY AND
THURSDAY AS THE UPPER RIDGE BEGINS TO SLIDE EAST INTO THE PLAINS
WHILE THE LEE TROUGH DEEPENS ALONG THE FRONT RANGE REGION OF
COLORADO. THIS WILL KEEP VERY WARM SOUTH TO SOUTHWEST SURFACE WINDS
ACROSS THE FORECAST AREA WITH HOT CONDITIONS EXPECTED. 700MB
TEMPERATURES OF +14 TO +17C SHOULD BE OVER THE PLAINS AND WITH
STRONG INSOLATION ALLOWING FOR MIXING POSSIBLY UP TO THIS HEIGHT,
HIGHS IN THE MID TO UPPER 90S LOOK VERY LIKELY ALTHOUGH A FEW SITES
MAY CRACK 100.

THURSDAY NIGHT INTO FRIDAY NIGHT WILL TURN SLIGHTLY MORE ACTIVE AS
THE MODELS DO HINT AT MODEST SHORT WAVE PLOWING INTO THE RIDGE AXIS
WHILE ALSO PUSHING A WEAK COLD FRONT INTO THE CENTRAL HIGH PLAINS.
ANTICIPATE AT LEAST A SLIGHT CHANCE FOR THUNDERSTORMS COMING FROM
THESE CONDITIONS THURSDAY NIGHT AND POSSIBLY FRIDAY NIGHT IF THE
BOUNDARY STALLS SOMEWHERE NEAR THE FORECAST AREA.  OTHERWISE,
TEMPERATURES SHOULD STAY ON THE WARM SIDE WITH READINGS IN THE 90S
EXPECTED.

&&

.AVIATION...

RATHER CHALLENGING AVIATION FORECAST FOR THE DDC, GCK AND HYS
TERMINALS OVER THE NEXT 24 HOURS AS MANY QUESTIONS EXIST INVOLVING
CONVECTION. INITIALLY FOR THIS AFTERNOON TO EVENING, A WARM FRONT
LIFTING NORTHWARD ACROSS FAR SOUTHERN KANSAS LOOKS TO BE SETTING THE
STAGE FOR CONVECTIVE INITIATION NORTH OF THE DDC AND GCK TERMINALS
WHILE LIKELY STAYING JUST SOUTH OF HYS.  NONETHELESS, THIS WILL HAVE
TO BE WATCHED VERY CLOSELY FOR THE HYS TERMINAL AS IT REMAINS
POSSIBLE CONVECTION COULD TRIGGER FURTHER NORTH THAN EXPECTED.
OTHERWISE, EXPECT CEILING AND VISIBILITY VALUES TO REMAIN VFR
THROUGH THE OVERNIGHT HOURS.  ATTENTION THEN SHIFTS TOWARD SUNDAY
MORNING AS FAVORABLE LIFT WILL BRING A CHANCE FOR SHOWERS TO MOST OF
THE TERMINALS. NOT EXPECTING ANY IFR CEILINGS BUT WOULD NOT BE
SHOCKED TO SEE SOME MVFR CEILINGS BY SUNRISE.
