AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
656 PM CDT SAT JUL 27 2013

...UPDATED FOR AVIATION...

.SYNOPSIS...
ISSUED AT 1110 AM CDT SAT JUL 27 2013

THE 12Z UPPER AIR ANALYSIS CONSISTS OF A MID TO UPPER LEVEL HIGH
SITTING ABOVE NORTHERN MEXICO, SOUTHERN ROCKIES, AND TEXAS. A MID
TO UPPER LEVEL LOW IS SPINNING ACROSS THE GREAT LAKES REGION.
THIS PLACES THE CENTRAL HIGH PLAINS UNDER NORTHWEST FLOW ALOFT. A
70+ KNOT JET EXTENDS FROM WYOMING, THROUGH WESTERN KANSAS, AND
INTO OKLAHOMA. MID LEVEL MOISTURE IS LOCATED ACROSS EASTERN
COLORADO AND WESTERN NEBRASKA. THIS IS EXPECTED TO ADVECT INTO
WESTERN KANSAS THIS EVENING. AS YOU HEAD TO THE SURFACE, AN AREA
OF LOW PRESSURE BECOMES APPARENT ACROSS EASTERN COLORADO WITH A
STATIONARY BOUNDARY EXTENDING ACROSS WESTERN AND SOUTHERN KANSAS.
SKIES ARE MOSTLY CLEAR ACROSS SOUTHWEST KANSAS WITH PARTLY TO
MOSTLY CLOUDY SKIES FOUND ACROSS NORTHERN AND CENTRAL KANSAS.
TEMPERATURES AT 11AM RANGE FROM THE LOWER 60S ACROSS NORTHERN
KANSAS WHERE CLOUDS ARE OBSERVED TO LOWER 80S ACROSS FAR
SOUTHWESTERN KANSAS.

&&

.SHORT TERM...(THIS EVENING THROUGH SUNDAY)
ISSUED AT 234 PM CDT SAT JUL 27 2013

THE SURFACE LOW MENTIONED IN THE SYNOPSIS HAS SHIFTED SLIGHTLY
SOUTHWARD INTO SOUTHEAST COLORADO THIS AFTERNOON WITH THE FRONTAL
BOUNDARY EXTENDING ACROSS SOUTHWEST KANSAS THEN INTO NORTHERN
OKLAHOMA. A FEW THUNDERSTORMS MAY FORM ALONG THIS BOUNDARY LATER
THIS AFTERNOON INTO THIS EVENING. A COUPLE OF THESE STORMS WILL HAVE
THE CAPABILITY TO BECOME SEVERE DUE TO MODERATE INSTABILITY AT THE
SURFACE AND THE 70+ JET ALOFT. THE MAIN THREAT WITH THESE SEVERE
STORMS WILL BE LARGE HAIL AND DAMAGING WINDS. A FEW STORMS MAY
CONTINUE INTO THE OVERNIGHT PERIOD AS A LOW LEVEL JET INCREASES
ACROSS WESTERN KANSAS. MEANWHILE, SCATTERED SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE ACROSS THE I-70 CORRIDOR LATE THIS
AFTERNOON INTO THE OVERNIGHT PERIOD AS LOW TO MID LEVEL MOISTURE
ADVECTS INTO THE AREA. WINDS THIS AFTERNOON WILL GENERALLY BE FROM
THE SOUTHEAST SHIFTING TO MORE OF AN EASTERLY DIRECTION TONIGHT.
LOWS TONIGHT WILL GENERALLY BE IN THE LOWER TO MID 60S.

A BETTER CHANCE OF THUNDERSTORMS IS EXPECTED TOMORROW AS A STRONG
UPPER LEVEL SHORTWAVE MOVES THROUGH WESTERN KANSAS. THE BEST CHANCE
OF PRECIPITATION WILL BE ACROSS NORTHERN KANSAS AND THE I-70
CORRIDOR. A FEW STORMS COULD BECOME STRONG IN THE AFTERNOON AND BE
CAPABLE OF PRODUCING STRONG WINDS AND SMALL HAIL. SKIES WILL
GENERALLY BE MOSTLY CLOUDY WITH WINDS FROM THE EAST SOUTHEAST. A
WIDE RANGE OF TEMPERATURES ARE EXPECTED TOMORROW WITH HIGH RANGING
FROM THE 70S ACROSS CENTRAL KANSAS TO UPPER 80S ACROSS FAR SOUTHWEST
KANSAS.

.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 216 PM CDT SAT JUL 27 2013

SUNDAY NIGHT LOOKS WET DUE TO A WARM FRONT BEING FROM NORTHWEST TO
SOUTHEAST ACROSS SOUTHWESTERN KANSAS.  AN UPPER LEVEL CYCLONE WILL
BE SLOWLY MOVING OVER WESTERN KANSAS.  LIKELY POPS WILL COVER OUR
SOUTHEAST PORTION OF OUR FORECAST AREA, AND SOME SUBSTANTIAL RAIN
WILL BE POSSIBLE SOUTHEAST OF A LINE FROM HAYS TO MEADE.  THE HIGHER
LEVEL MOISTURE WILL BE THERE AND THE WARM FRONT WILL LIFT NORTHEAST
DURING SUNDAY NIGHT.  THE LIKELY CHANCES FOR PRECIP WILL EXIST
THROUGH SUNDAY NIGHT, THEN GRADUALLY SLIDE DOWNWARD INTO THE CHANCE
CATEGORY MONDAY AS THEY ALSO WILL TREND TO THE EAST.  TUESDAY WILL
BE DRY MUCH OF THE DAY WITHOUT ANY PRECIPITATION, BUT AS A FRONT
LIFTS NORTH AND THAT SHORT WAVE ADVANCES EAST, THE CHANCES FOR
PRECIP WILL DIMINISH TUESDAY.  HOWEVER, BY LATE IN THE AFTERNOON, A
SURFACE TROUGH WILL SLIDE INTO WESTERN KANSAS FROM COLORADO,
BRINGING A SLIGHT CHANCE FOR A FEW THUNDERSTORMS NEAR THE COLORADO
BORDER.  BOTH MONDAY AND TUESDAY SHOULD SEE HIGH TEMPERATURES IN THE
MID TO UPPER 80S, WITH MINIMUM TEMPERATURES BOTH SUNDAY NIGHT AND
MONDAY NIGHT IN THE MID 60S RANGE.

UPPER HIGH PRESSURE WILL CONTINUE TO DOMINATE OVER THE SOUTHWESTERN
UNITED STATES, FROM TUESDAY INTO FRIDAY.  MINOR SHORT WAVES WILL
CROSS SOUTHEAST THROUGH THE CENTRAL PLAINS WEDNESDAY AND THURSDAY,
BRINGING A SLIGHT CHANCE TO A CHANCE FOR THUNDERSTORMS BOTH
AFTERNOONS.  JUST WHEN IT LOOKED LIKE WE WOULD BE OUT OF THE
NORTHWEST FLOW, YET ANOTHER SHORT WAVE WILL CROSS WESTERN KANSAS
FRIDAY NIGHT AND SATURDAY, PER THE ECMWF MODEL.  ALSO A WARM FRONT
SHOULD MOVE INTO WESTERN KANSAS, BRINGING ANOTHER CHANCE FOR
THUNDERSTORMS INTO SOUTHWESTERN KANSAS AND SURROUNDING AREAS.  THE
FOLKS AROUND WESTERN KANSAS SHOULD BE DELIGHTED AT THE NUMEROUS
CHANCES FOR RAIN.

HIGH TEMPERATURES WILL GO THROUGH A SLOW WARMING TREND FROM
WEDNESDAY INTO FRIDAY.  WEDNESDAY'S HIGH TEMPERATURES WILL AVERAGE
AROUND 90F, THURSDAY'S IN THE LOWER TO MID 90S, AND FRIDAY'S PEAKING
IN THE LOWER 90S NEAR HAYS AND WAKEENEY, AND APPROACHING THE 100F
DEGREE MARK DOWN SOUTH ALONG THE OKLAHOMA BORDER.  A FRONT WILL DIVE
BACK SOUTH INTO OKLAHOMA SATURDAY, WITH MAX TEMPERATURES TOPPING OUT
FROM THE MID 80S NORTH OF I-70 TO NEAR 90 ALONG THE OKLAHOMA
BORDER.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING)
ISSUED AT 655 PM CDT SAT JUL 27 2013

A SURFACE STATIONARY/WEAK COLD FRONT FROM WEST CENTRAL KANSAS,
EXTENDING SOUTHEAST INTO SOUTH CENTRAL KANSAS IS THE FOCUS FOR A
COUPLE OF DISTINCT AREAS OF CONVECTION THIS EVENING. BOTH CONVECTIVE
CLUSTERS WILL HAVE IMPACTS FOR THE TERMINALS AT HYS, GCK AND DDC AT
LEAST THROUGH THE MID TO LATE EVENING HOURS. BASED ON HRRR MODEL
TRENDS SHOWERS AND THUNDERSTORMS COULD REMAIN IN THE VICINITY OF
KHYS FOR SEVERAL HOURS THIS EVENING. THE BEST CHANCE FOR STRONG
OUTFLOW THUNDERSTORM WINDS WILL BE AT GCK AND KDDC AS THE
THERMODYNAMIC PROFILES ARE FAR MORE DRY ADIABATIC IN THE LOW LAYERS
AT THESE SITES THAN FAR BEHIND THE FRONT AT HYS.
