AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
310 PM CDT SAT JUN 30 2012

...UPDATED TO THE LONG TERM DISCUSSION...

.SYNOPSIS...
ISSUED AT 1225 PM CDT SAT JUN 30 2012

WV IMAGERY AND 12Z UPPER AIR ANALYSIS INDICATE AN UPPER LEVEL
SHORTWAVE TROUGH OF LOW PRESSURE TRANSITIONING SLOWLY EAST ACROSS
THE WESTERN HIGH PLAINS OF SOUTHWEST NEBRASKA AND NORTHWEST KANSAS.
THIS FEATURE IS HELPING TO PRODUCE A FEW ISOLATED SHOWERS ACROSS
NORTH CENTRAL KANSAS EARLY THIS AFTERNOON. MEANWHILE, AN UPPER
LEVEL RIDGE OF HIGH PRESSURE IS SET UP ACROSS THE DESERT
SOUTHWEST WHILE A GENERAL WESTERLY FLOW ALOFT PERSISTS ACROSS THE
NORTHERN PLAINS. NEAR THE SURFACE, A SURFACE TROUGH OF LOW
PRESSURE EXTENDS SOUTHWEST FROM SOUTH CENTRAL NEBRASKA DOWN ACROSS
WESTERN KANSAS. SURFACE DEWPOINTS ARE GENERALLY IN THE 50S(F)
ACROSS SOUTH CENTRAL AND SOUTHWEST KANSAS.

&&

.SHORT TERM...(THIS EVENING THROUGH TOMORROW)
ISSUED AT 132 PM CDT SAT JUN 30 2012

SHORT TERM MODELS INDICATE A SECONDARY UPPER LEVEL SHORTWAVE
EJECTING EAST OUT OF THE ROCKIES TONIGHT EVEN AS LARGE SCALE UPPER
LEVEL RIDGING BEGINS TO REBUILD ACROSS THE CENTRAL PLAINS. HOWEVER,
WIDESPREAD SHOWER AND THUNDERSTORM CHANCES ARE NOT THAT GREAT WITH A
FAIRLY WEAK FLOW ALOFT STILL IN PLACE ACROSS THE WESTERN HIGH
PLAINS. REGARDLESS, ENOUGH INSTABILITY EXISTS THAT A FEW ISOLATED
THUNDERSTORMS WILL BE POSSIBLE IN THE VICINITY OF THE SURFACE TROUGH
LATE THIS AFTERNOON AND EVENING ONCE THE CAP WEAKENS. THE BEST
CHANCE FOR ANY STORM DEVELOPMENT WILL BE ACROSS WEST CENTRAL AND
CENTRAL KANSAS WHERE THE PROXIMITY TO A STALLED FRONTAL BOUNDARY
ALONG THE NEBRASKA BORDER WILL BE BEST.

TEMPERATURES TONIGHT WILL BE SIMILAR TO THE LOWS THIS MORNING WITH
THE SAME GENERAL AIR MASS IN PLACE. LOOK FOR LOWS MAINLY DOWN INTO
THE LOWER TO MID 70S(F) WITH A FEW UPPER 60S(F) POSSIBLE. HIGH
TEMPERATURES WILL REMAIN HOT SUNDAY AS UPPER LEVEL RIDGING REBUILDS
ACROSS THE CENTRAL PLAINS. A SURFACE TROUGH ACROSS WESTERN KANSAS
WILL RETREAT BACK TO THE COLORADO BORDER BY EARLY SUNDAY RETURNING
A MODEST LOW LEVEL SOUTHERLY FLOW INTO WESTERN KANSAS. THE NAM AND
GFS SHOW H85 TEMPERATURES NOT CHANGING MUCH WITH MID TO UPPER 20S(C)
ACROSS CENTRAL KANSAS TO THE NEAR 30C ALONG THE COLORADO BORDER.
LOOK FOR HIGHS UP NEAR 100F ACROSS MUCH OF SOUTH CENTRAL AND
SOUTHWEST KANSAS BY SUNDAY AFTERNOON.

.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 250 PM CDT SAT JUN 30 2012

LITTLE CHANGE IN THE OVERALL PATTERN IS EXPECTED. THE LONG RANGE
MODELS ALL INDICATE THAT THE CENTER OF THE UPPER LEVEL RIDGE WILL
GRADUALLY RETROGRADE BACK OVER KANSAS/NEBRASKA. THE QUESTION IS IF
THE RIDGE WILL BE FAR ENOUGH NORTH THAT THE HOTTEST TEMPERATURES
WILL BE ACROSS NORTHERN KANSAS AND NEBRASKA. IRREGARDLESS IT WILL
CONTINUE HOT WITH ABOVE NORMAL TEMPERATURES. WITH WEAK FLOW ALOFT
AND GENERALLY VERY HOT MID LEVEL TEMPERATURES THE PROSPECT FOR
PRECIPITATION ACROSS MY CWA IS VERY LOW, ALTHOUGH NOT ZERO.

BEYOND THIS PERIOD THERE STILL IS SOME INDICATION THAT THE RIDGE
WILL RETROGRADE FAR ENOUGH WEST WITH SOME DEEPENING OF THE UPPER
FLOW ACROSS THE EASTERN U.S. THAT A FROPA CAN BE EXPECTED. BASED
ON MJO COMPOSITES AND FORECASTS, IT WOULD SEEM POSSIBLE THAT THIS
COULD HAPPEN. BUT WITHOUT ANY CONFIDENCE THIS FAR OUT, WILL
CONTINUE WITH ABOVE NORMAL TEMPERATURES AND BELOW NORMAL
PRECIPITATION IN THE 8-14 DAY OUTLOOK PERIOD.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)
ISSUED AT 1210 PM CDT SAT JUN 30 2012

ISOLATED THUNDERSTORMS MAY BE POSSIBLE ALONG A SURFACE TROUGH
ACROSS WESTERN KANSAS LATE THIS AFTERNOON AND EVENING...INCLUDING
IN THE VICINITY OF ALL TAF SITES. OTHERWISE, VFR CONDITIONS WILL
PREVAIL AT ALL TAF SITES THROUGH EARLY SUNDAY MORNING. AS FOR
WINDS, A SURFACE TROUGH ACROSS WESTERN KANSAS WILL RETREAT WEST
NEAR THE COLORADO BORDER TONIGHT. AS A RESULT, LIGHT AND VARIABLE
WINDS THIS AFTERNOON WILL BECOME SOUTHERLY 10 TO 15KT TONIGHT.
