AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
330 PM CDT FRI JUN 18 2010

.DISCUSSION...

DAYS 1-2...

THE MAIN FORECAST CHALLENGES ARE CHANCES FOR THUNDERSTORMS TONIGHT
AS A WARM FRONT MOVES NORTH, THEN THUNDERSTORM CHANCES INTO SATURDAY
IN THE HAYS AREA WITH THE WARM FRONT.

AN UPPER LEVEL TROUGH WILL CONTINUE TO MOVE ACROSS THE NORTHERN
PLAINS AND INTO THE UPPER MIDWEST TONIGHT WHILE UPPER LEVEL RIDGING
MOVES BACK INTO THE PLAINS OVERNIGHT. AS MID LEVEL HEIGHTS RISE OVER
WESTERN KANSAS, A WEAK COLD FRONT OVER THE OKLAHOMA PANHANDLE, WILL
MOVE SLOWLY NORTH AS A WARM FRONT. THE RUC MODEL SHOWS A FEW
THUNDERSTORMS POSSIBLE ALONG THE WARM FRONT ALONG THE OKLAHOMA
BORDER WHILE THE HIGH RESOLUTION WRF SHOWS SOME MORE STORMS MOVING
EAST ACROSS OUR NORTHERN FA FROM WAKEENEY TO ELLIS. THE MAIN
NORTHERN BRANCH JET IS WELL NORTH OF THE REGION WHILE THE
SUBTROPICAL JET IS NOW SOUTH OF KANSAS. FORECAST SOUNDINGS SHOW
ABOUT 55 KTS STILL AT 200MB WHICH COULD SUPPORT A FEW ISOLATED
THUNDERSTORMS WITH HAIL UP TO NICKELS BUT NOT EXPECTING SEVERE. WILL
ADD A SMALL POP ACROSS THE SOUTH FA AND MAINTAIN SMALL POPS NORTH
TONIGHT TO COVER.

FOR SATURDAY LOOK FOR UPPER LEVEL RIDGING TO CONTINUE WITH THE WARM
FRONT MOVING INTO THE NORTH FA AROUND HAYS. A DRYLINE WILL ALSO PUSH
EASTWARD TOWARD DODGE CITY AND WAKEENEY TO MEADE WITH A TRIPLE POINT
UP AROUND HAYS. 50 TO 70KTS AT 200MB ALONG WITH AROUND 2000 J/KG
CAPE COULD SUPPORT SOME SEVERE IN THE HAYS AREA BY LATE AFTERNOON IF
A STORM CAN BREAK THROUGH THE WARM MID LEVEL CAP. SURFACE WINDS WILL
BE GUSTY FROM THE SOUTH AT 20 TO 35 MPH WITH LESS WINDS IN THE WEST
CLOSER TO THE SURFACE TROUGH.

A MILD NIGHT IS IN STORE FOR SATURDAY NIGHT AS SOUTH WINDS CONTINUE
AT 15 TO 25 MPH AS A LOW LEVEL JET CRANKS UP. EXPECT CLEAR SKIES. ON
SUNDAY THE WARM FRONT WILL BE UP INTO NEBRASKA WITH SOUTH WINDS AT
20 TO 35 MPH. THE DRYLINE AGAIN IS FORECAST TO PUSH EAST TOWARDS
WAKEENEY TO DODGE CITY AND MEADE. MODELS SHOW SOME WARM AIR AT MID
LEVELS AND A LACK OF ANY SIGNIFICANT BOUNDARIES AND LIMITED MOISTURE
CONVERGENCE WHICH SHOULD PRECLUDE THUNDERSTORM CHANCES. THE NAM IS
SHOWING SOME THUNDERSTORMS IN THE FAR WEST FA IN THE AFTERNOON WHERE
AN UPPER LEVEL JET IS MOVING INTO EASTERN COLORADO. WILL KEEP A 10
PERCENT POP OUT THERE.

FOR LOWS TONIGHT LOOK FOR UPPER 60S WEST TO MID 70S SOUTHEAST FA.
HIGHS ON SATURDAY SHOULD BE AROUND 100 WEST OF THE DRYLINE FROM
GARDEN CITY TO LIBERAL AND WEST WITH MID TO UPPER 90S ELSEWHERE.
LOWS WILL BE A BIT WARMER ON SATURDAY NIGHT WITH 70 FAR WEST TO THE
MID 70S EAST. AND FOR HIGHS ON SUNDAY LOOK FOR AROUND 102 WEST OF
THE DRYLINE FROM NEAR WAKEENEY TO JUST WEST OF DODGE CITY TO MEADE
WITH UPPER 90S EAST.

DAYS 3-7...

I DID NOT MAKE ANY MAJOR CHANGES TO THE EXTENDED AS IT APPEARS THAT A
SUMMER PATTERN MAY HAVE SET IN.  MODELS GRADUALLY BUILD HEIGHTS AND
WEAKEN WINDS ALOFT OVER MY CWA.  HOWEVER WE WILL STILL BE ON THE
SOUTHERN EDGE OF THE STRONGER WESTERLIES SO A SURPRISE OR TWO COULD
OCCUR.  THE BIGGEST THREAT WOULD BE A BOUNDARY SLIPPING DOWN INTO
THE AREA FROM THE NEARLY NIGHTLY OCCURRENCE OF MCS'S ROLLING ACROSS
THE NORTHERN PLAINS.  ANOTHER SOURCE OF A SURPRISE EVEN MAY BE THAT
IF TROUGH IN THE WEST BECOMES DEEP ENOUGH AND THE CENTER OF THE
UPPER RIDGE IS EAST OF 100W, THEN THERE COULD BE A MINOR DISTURBANCE
MOVING NORTH OUT OF THE TROPICS.  THIS IS A FAR FETCHED POSSIBILITY
BUT I WOULD NOT BE TOTALLY SHOCKED IF IT HAPPENED.  TEMPERATURES
WILL BE SEASONAL TO ABOVE WITH READINGS IN THE 95 TO 100 DEGREE
RANGE, AGAIN BARRING ANY SURPRISE BOUNDARY DROPPING INTO THE AREA.
IF IT WERE'NT SO GREEN AND WET TEMPERATURES WOULD LIKELY BE 3 TO 5
DEGREES WARMER BUT WILL HOLD DOWN FOR NOW.

&&

.AVIATION...

SURFACE LOW PRESSURE WILL BE DEEPENING IN EASTERN COLORADO AND WILL
HELP SOUTHERLY SURFACE WINDS TO DEVELOP.
