Area forecast discussion, Sep 4, 3:00 PM CDT, 12 hours 5 minutes before
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. 63
