AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
310 PM CDT WED AUG 17 2005

.DISCUSSION...

DAYS 1-2...
FORECAST CHALLENGE WILL BE THE POSSIBILITY FOR ISOLATED THUNDERSTORMS
THIS EVENING AND THURSDAY EVENING AND THEN THE ARRIVAL OF THE FRONT
ON FRIDAY AFTERNOON.

AFTERNOON CU HAS BEE DEVELOPING ALONG A WARM FRONTAL BOUNDARY THAT
IS LINGERING OVER THE EASTERN PORTIONS OF THE CWA THIS AFTERNOON.
A WEAK CONVERGENCE LINE WAS ALSO EVIDENT IN THE VIS SAT IMAGERY
AND SFC PLOTS FROM KP28 TO NEAR KTCC.  SOME STORMS WERE ALREADY
STARTING TO FIRE IN THE WEST TEXAS PANHANDLE.

THE WATER VAPOR IMAGERY IS SHOWING A COUPLE OF WAVES APPROACHING
THE CENTRAL PLAINS.  ONE WAS MOVING TOWARD NEBRASKA WHILE THE
OTHER WAVE WAS MOVING FROM NEW MEXICO INTO THE TEXAS PANHANDLE
REGION.  THESE IMPULSES WILL HELP FOCUS THUNDERSTORM DEVELOPMENT TO
THE NORTH AND SOUTH OF SOUTHWEST KANSAS BUT WITH THE ATMOSPHERE
OVER SOUTHWEST KANSAS FAIRLY UNSTABLE AND NEARLY UNCAPPED, THINK
THERE WILL STILL BE SOME WIDELY SCATTERED TO ISOLATED THUNDERSTORMS
DEVELOPING.  BASED ON AFTERNOON TRENDS, THINK THAT THE BEST CHANCE
WILL BE IN THE EASTERN CWA WITH DIMINISHING POSSIBILITIES FARTHER
TO THE NORTHWEST.

ON THURSDAY, THE SURFACE TROUGH MOVES THROUGH ALL BUT THE SOUTHEAST
CORNER OF THE CWA.  PREVIOUS FORECASTS HAD A SLIGHT CHANCE FOR
THUNDERSTORMS IN THAT AREA BY LATE AFTERNOON AND WILL LEAVE INTACT.

THE LONG ANTICIPATED FRONT THAT WILL COOL THE WEATHER DOWN A BIT
THIS WEEKEND WILL BE ROLLING INTO SOUTHWEST KANSAS LATE FRIDAY
AFTERNOON AND EVENING. WILL INTRODUCE A SLIGHT CHANCE FOR
THUNDERSTORMS TO THE NORTHERN PART OF THE CWA BY MID AFTERNOON AND
SPREAD THESE SOUTH INTO THE EVENING HOURS.

A VERY WARM AIRMASS WILL PUSH DAYTIME HIGHS WELL ABOVE NORMAL
BEHIND THE TROUGH ON THURSDAY AND CONTINUE AHEAD OF THE FRONT ON
FRIDAY. TEMPERATURES ON THURSDAY AND FRIDAY SHOULD BE IN THE UPPER
90S TO AROUND 100 AND HAVE ADJUSTED THE MAX TEMPS IN THE GRIDS UP
ACCORDINGLY.

DAYS 3-7...
MODELS ARE IN GOOD AGREEMENT THAT COLD FRONT WILL MOVE THRU FRIDAY
NIGHT. THINK THE BEST CHANCE OF RAIN WILL BE ALONG OR JUST BEHIND
THE FRONT SO WILL GO 30-40 PERCENT FOR THIS PERIOD. WILL GRADUALLY
TAPER POPS OFF SATURDAY-SATURDAY NIGHT WITH SOME LINGERING POST
FRONTAL SHOWERS POSSIBLE. MODELS SHOW HIGH 850MB RH (AKA LOW CLOUD)
HANGING AROUND WESTERN KS ON SATURDAY, AND TEMPS SHOULD REMAIN
RATHER COOL DURING THE DAY. WILL LOWER GOING HIGHS A COUPLE DEGREES
OR SO BUT FOR THE MOST PART THE GOING FORECAST HAD THE RIGHT IDEA.
CLEARING SKIES SATURDAY NIGHT AND SURFACE RIDGE BUILDING IN WILL
MAKE FOR A COOL NIGHT SO HAVE LOWERED GOING LOWS A FEW DEGREES BACK
INTO THE 50S MOST AREAS. SUNNY SKIES RETURN FOR SUNDAY AND MONDAY SO
TEMPS WILL MODERATE BACK INTO THE 80S. GFS/ECMWF BOTH HINT AT
BRINGING SHORTWAVE ENERGY INTO THE PLAINS AROUND TUESDAY WITH OF
COURSE TIMING BEING AN ISSUE. WILL THROW IN SOME LOW POPS AND WILL
ADJUST TIMING IF NEED BE IN THE COMING DAYS. ANOTHER FRONT MAY BE
APPROACHING BY THURSDAY OF NEXT WEEK, BUT MAY NOT MAKE AS MUCH
PROGRESS TO THE SOUTH AS THE PREVIOUS FRONTS HAVE.
