Area forecast discussion, May 6, 3:37 AM CDT, 7 hours 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
337 AM CDT SUN MAY 6 2007

.DISCUSSION...

DAYS 1-2...

MAIN FORECAST CHALLENGES TODAY ARE WHERE SURFACE BOUNDARY ENDS UP
AND THE CHANCES OF MORE SEVERE WEATHER.

MODELS SHOW LOTS OF CLOUDS TODAY THAT MAY KEEP THE INSTABILITY A
BIT WEAKER. THE BEST THREAT FOR SEVERE WILL BE MAINLY EAST OF
DODGE CITY INTO THE ASHLAND TO LARNED AREA WHERE THE SURFACE WINDS
CAN BE MORE BACKED AND CONVERGENT. IF MORE SUNSHINE COMES OUT IN
THAT AREA THE THREAT FOR A FEW TORNADOS WILL BE POSSIBLE. ELSEWHERE
A FEW THUNDERSTORMS MAY BE SEVERE WITH A MORE OF A HAIL THREAT.
ANOTHER CONCERN IS POSSIBLE FLOODING TONIGHT WITH QPF OVER AN INCH
OR TWO JUST EAST OF THE BOUNDARY.

A COLD FRONT HAS PUSHED EASTWARD TO JUST EAST OF DODGE CITY AND
WILL SLOWLY MOVE BACK A BIT TO THE WEST FROM MEADE TO DODGE CITY
AND HAYS. EXPECT CLOUDY SKIES THIS MORNING WITH MOSTLY CLOUDY IN
THE AFTERNOON WITH HIGHS IN THE 70S. ANOTHER SHORTWAVE WILL ROUND
THE BASE OF THE UPPER TROUGH OVER NEW MEXICO AND MOVE
NORTHEASTWARD INTO KANSAS TONIGHT WITH ANOTHER ROUND OF HEAVY
THUNDERSTORMS. THIS WAVE WILL PUSH THE COLD FRONT INTO CENTRAL KANSAS
BY MONDAY MORNING. THE UPPER LOW WILL CONTINUE TO SLOWLY FILL AND
WEAKEN TO OUR WEST BUT CONTINUE TO BRING SOME CHANCE OF RAIN INTO
MONDAY NIGHT.

DAYS 3-7...

THE EXTENDED FORECAST WAS ON TRACK AND NO LARGE CHANGES WERE MADE.
SMALL POPS WERE EXTENDED INTO EARLY THURSDAY PER COLLABORATION.
A VERY SLOW MOVING UPPER TROUGH WILL LINGER OVER THE SOUTHERN
ROCKIES INTO WEDNESDAY.

FRONT OVER SOUTH CENTRAL KS MOVES SLOWLY NW AS A WARM FRONT.
