AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
412 AM CDT TUE AUG 20 2002

MAIN FORECAST PROBLEMS ARE PRECIP CHANCES THROUGH TONIGHT AND AGAIN
THE END OF THE WEEK. CONVECTION CONTINUES ALONG AREA OF GOOD
ISENTROPIC LIFT NEAR THE WARM FRONT AT 850MB. EXPECT SCATTERED
PRECIP TO DIMINISH ACROSS MY AREA THIS MORNING...AS THE WARM FRONT
CONTINUES TO MOVE NORTH AND ISENTROPIC LIFT WEAKENS. PRECIP WILL
LINGER THE LONGEST IN THE NORTHWEST CORNER. SERIES OF SHORT WAVES
MOVING ACROSS THE NORTHERN STATES WILL PUSH THE COLD FRONT BACK
TOWARD THE REGION THE LATTER HALF OF THE WEEK. THE FIRST ONE WILL
PUSH IT INTO IOWA BY THURSDAY. HAVE INCLUDED PRECIP CHANCES NEAR THE
IOWA-MISSOURI BORDER THURSDAY NIGHT INTO FRIDAY. THE SECOND IS
PROGGED TO PUSH THE FRONT ACROSS THE ENTIRE FORECAST AREA FRIDAY
NIGHT INTO SATURDAY. HAVE THEREFORE LEFT LOW POPS IN FRIDAY NIGHT
AND THE SOUTHERN SECTIONS ON SATURDAY.

AS WARM FRONT PUSHES NORTH TODAY AND RIDGE BUILDS IN...850MB TEMPS
INCREASE TO AROUND 20 TO 22C TODAY IN THE WESTERN SECTIONS OF THE
FORECAST AREA. 850MB TEMPS CONTINUE TO INCREASE ON WEDNESDAY...AHEAD
OF THE APPROACHING COLD FRONT. THAT WILL SEND AFTERNOON TEMPERATURES
GENERALLY INTO THE UPPER 80S TO AROUND 90 TODAY AND WELL INTO THE
90S ON WEDNESDAY. READINGS WILL BE COOLER IN THE NORTHEAST SECTIONS
OF THE FORECAST AREA THROUGH THE WEEK.

NONE EXPECTED THROUGH MONDAY.

NOT ANTICIPATED.

DISCUSSION: AN AREA OF SHOWERS AND THUNDERSTORMS WILL CONTINUE TO
MOVE SOUTH AND GRADUALLY END THIS MORNING. THIS AREA OF
PRECIPITATION WILL LEAVE A BOUNDARY THAT MAY BE THE FOCUS FOR
ADDITIONAL SHOWERS AND THUNDERSTORMS ACROSS NORTHERN MISSOURI LATER
TODAY. HOWEVER THE CHANCE OF ADDITIONAL RAIN LATER TODAY IS FAIRLY
SMALL. THERE IS A BETTER CHANCE OF RAIN LATE TONIGHT ACROSS THE
NORTHWEST CORNER OF MISSOURI...AS ANOTHER AROUND OF OVERNIGHT
SHOWERS AND THUNDERSTORMS APPROACHES THE AREA. OTHERWISE A SERIES OF
SHORTWAVES WILL MOVE ACROSS THE NORTHERN STATES...BRINGING ANOTHER
CHANCE OF PRECIPITATION LATER THIS WEEK. AT THIS TIME SEVERE WEATHER
IS NOT ANTICIPATED.
