AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
3 PM CDT MON SEP 4 2000

PRECIPITATION CHANCES AND TEMPERATURES CONTINUE TO BE THE MAIN
FORECAST CONCERNS...

EASTERLY FLOW CONTINUES IN THE LOW LEVELS ACROSS THE CWA AS GREAT
LAKES SURFACE HIGH BUILDS SOUTHWARD. WAA AND SHEAR IN CONVERGENCE
ZONE KEEPING PRECIP GOING IN CENTRAL KANSAS. TEMPS HAVE AGAIN RISEN
WELL INTO THE 90S ACROSS THE CWA WHERE THE SUN HAS BEEN OUT THIS
AFTERNOON. MOS AND FAN GUIDANCE CONTINUE TO BE TOO COOL IN
FORECASTING HIGHS AND LOWS AND WILL TREND THIS FORECAST ABOVE
MOS/FAN GUIDANCE AGAIN...A LITTLE MORE IN LINE WITH MESOETA.

NEXT SHORTWAVE WILL MOVE INTO CENTRAL KANSAS TONIGHT WITH BEST LIFT
AND CONVERGENCE CONTINUING IN BAROCLINIC ZONE OVER CENTRAL NEB/KS
THROUGH 12Z. WILL TREND HIGHEST POPS TONIGHT OVER THE WESTERN
CWA...BUT KEEP POP GOING ALL AREAS. EXPECT CONVECTION WEST TO
GRADUALLY SHIFT/DEVELOP EASTWARD SLIGHTLY THROUGH THE NIGHT. ANY
PRECIP GOING EARLY TUESDAY SHOULD GRADUALLY DIMINISH FROM NORTHWEST
TO SOUTHEAST ACROSS THE CWA THROUGH THE DAY. CONCERN ON TEMPS FOR
TUESDAY IS THE FACT THAT AFTERNOON SUNSHINE WILL HELP TO PUSH TEMPS
TO AROUND 90 SOUTHWEST AND THE LOWER 80S FAR NORTHEAST...WELL ABOVE
FAN TEMPS IN THE 70S.

YET ANOTHER WEAKER WAVE TO MOVE ACROSS THE NORTHERN EDGE OF UPPER
HIGH TUESDAY NIGHT AND COULD BRING SOME PRECIP AS FAR EAST AS
NORTHCENTRAL PORTIONS LATE IN THE NIGHT...ALTHOUGH CHANCES ARE
SMALL...AND EVEN LESS FURTHER EAST. WILL GO 20 PERCENT NORTHCENTRAL
AND LEAVE EAST DRY TUESDAY NIGHT. UPPER HIGH CENTER DOMINATES
WEDNESDAY WITH A RETURN TO MORE SOUTHERLY...AND SLIGHTLY WARMER
TEMPS. WILL GENERALLY GO 85 TO 90 NORTHEAST TO 90 TO 95 WEST.

.TOP...NONE.
