Severe Thunderstorm Warning 174, NWS Kansas City, MO

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
255 PM CDT THU JUL 04 2002

MAIN PROBLEMS FOR TODAY INVOLVE RAIN CHANCES FOR TOMORROW AND IN THE
EXTENDED.

THUNDERSTORMS POPPED UP ACROSS THE SOUTHERN AND WESTERN HALF OF THE
CWA TODAY.  THE TOPEKA 12Z SOUNDING WAS SHOWING A DEEP LAYER OF
MOISTURE UP THROUGH 300 MB WITH LITTLE TO NO CAPPING ACROSS EAST
KANSAS AND WEST MISSOURI. THE DEEP LAYER MOISTURE AXIS LOOKS TO
SLIDE TO THE WEST JUST ENOUGH TO REMOVE THE CHANCE OF RAIN FROM
CENTRAL MISSOURI FOR FRIDAY...THEREFOR I HAVE ONLY INTRODUCED THE
CHANCE OF THUNDERSTORMS INTO THE WEST HALF OF THE CWA. FOR THE
REMAINDER OF THE SHORT TERM I HAVE MADE FEW CHANGES TO THE GOING
FORECAST THROUGH THE FIRST HALF OF THE WEEKEND.

FOR SUNDAY...WITH THE LACK OF FIRM FOCUS FOR PRECIPITATION...I HAVE
SPREAD THE CHANCES OF THUNDERSTORMS ACROSS THE CWA THROUGH THE EARLY
EVENING HOURS.  MONDAY LOOKS LIKE WE COULD ESCAPE ANY RAIN AS THE
MODELS ARE NOW SLOWING DOWN THE PROGRESSION OF THE SHORT WAVE MOVING
OVER THE TOP OF THE RIDGE.  THEREFOR...I HAVE REMOVED THE CHANCE OF
THUNDER FROM THE FORECAST FOR MONDAY BUT KEPT IT FOR TUESDAY AND A
LITTLE INTO TUESDAY NIGHT AS THE WAVE MOVES THROUGH THE AREA.  THE
REMAINDER OF THE FORECAST LOOKED GOOD.

CUTTER

414 AM...
MAIN FORECAST DILEMMAS CONTINUE TO BE WITH PRECIPITATION CHANCES
TODAY AND THEN AGAIN IN THE EXTENDED RANGE.

FORECAST AREA REMAINS UNDER UPPER LEVEL HIGH PRESSURE
TODAY...WITH SHEAR AXIS STRETCHING FROM CENTRAL TEXAS NORTHEASTWARD
THROUGH CENTRAL OKLAHOMA AND KANSAS. THE UPPER LOW WILL CONTINUE
RETROGRADING TODAY. DEEP MOISTURE WILL STILL BE IN PLACE...SO
ANTICIPATE SCATTERED DIURNALLY INDUCED CONVECTION SIMILAR TO
YESTERDAYS ACTIVITY AGAIN TODAY. PRECIPITATION TOTALS WILL VARY
GREATLY ACROSS THE AREA...WITH LOCALLY HEAVY AMOUNTS POSSIBLE.
EXPECT THE BULK OF THE RANDOM ACTIVITY TO OCCUR DURING THE AFTERNOON
HOURS...DIMINISHING AFTER SUNSET. HIGH TEMPERATURES TODAY SHOULD BE
IN LINE WITH WEDNESDAY HIGHS...AS NO BIG CHANGES IN LOW LEVEL
TEMPERATURE FIELDS WILL OCCUR. THINK CLOUD COVER WILL CONSIST
PRIMARILY OF A BROKEN MID LEVEL DECK WITH SOME SCATTERED LOW CLOUDS
DURING TIME OF PEAK HEATING...SO UPPER 80S TO NEAR 90 DEGREE
READINGS SEEM ATTAINABLE AGAIN TODAY. UPPER LOW SHOULD BE FAR ENOUGH
WEST TO NOT WARRANT MENTION OF SCATTERED THUNDERSTORMS ON FRIDAY.
TEMPERATURES WILL BE SLIGHTLY WARMER FOR THE WEEKEND...WITH
AFTERNOON HEAT INDICES POTENTIALLY NEARING 100 DEGREES ON SATURDAY
AND SUNDAY.

IN THE EXTENDED...A SERIES OF UPPER LEVEL DISTURBANCES ARE PROGGED
TO AFFECT THE FORECAST AREA AT THE BEGINNING OF NEXT WEEK. MODELS
CONTINUE TO ACCELERATE A SHORTWAVE MOVING THROUGH KANSAS ON SUNDAY
NIGHT. HAVE INTRODUCE THUNDERSTORMS TO FORECAST FOR WESTERN COUNTY
WARNING AREA BEGINNING SUNDAY AFTERNOON. ANOTHER FEATURE OF INTEREST
IS A NORTHERN PLAINS SURFACE FRONT...FORECAST TO MOVE THROUGH THE
AREA ON SUNDAY AND MONDAY. CONVERGENCE ALONG THE FRONT APPEARS
WEAK...BUT ABSENCE OF A CAP SHOULD ALLOW ADDITIONAL THUNDERSTORMS TO
DEVELOP IN ASSOCIATION WITH THE FRONTAL PASSAGE. DUE TO THE MODEL
ACCELERATION OF THESE FEATURES...EXPECT THE SHORTWAVES AND THE FRONT
TO BE NON-INFLUENTIAL FACTORS BY LATE MONDAY...SO HAVE REMOVED
PRECIPITATION CHANCES FOR TUESDAY. TEMPERATURES ON TUESDAY AND
WEDNESDAY SHOULD BE SLIGHTLY COOLER.
