AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
335 PM CDT MON JUN 22 1998

...FLASH FLOODING POTENTIAL MAIN CONCERN THIS FORECAST...

WITH LAST NIGHTS CONVECTIVE RAINS...MAIN CONCERN IS CENTERED ON
POTENTIAL FOR FLASH FLOODING TONIGHT AND TUESDAY FORENOON. FFG
VALUES MAINLY IN THE ONE TO TWO INCH RANGE. THESE AMOUNTS COULD
EASILY BE MET TONIGHT WITH FORECAST SCENARIO.

WARMFRONT LIKELY ALONG SRN KS BORDER ATTM. STG THETA-E ADVECTION
INTO THE NORTHEAST COUNTIES TO OCCUR THIS EVENING WITH GENERATION OF
CONVECTION AGAIN LIKELY. SLOW MOVEMENT OF THIS ACTIVITY WILL PRODUCE
FIRST THREAT OF FLASH FLOODING.

SECOND THREAT OF SGFNT CONVECTION WILL COME WITH CONVECTIVE COMPLEX
OVER THE HIGH PLAINS. HAVE HAD TELCON WITH HPC AND FEEL MAX
PRECIPITATION WILL INDEED BE CLOSER TO WARM FRONTAL ZONE...BUT I
BELIEVE THE WARM FRONT WILL BE FURTHER SOUTH IN KANSAS. MCS MOTION
MACRO FROM GRIDDS SUGGESTS MCS IN NE WILL MOVE SOUTHEAST INSTEAD OF
EAST AS IMPLIED BY SUBJECTIVE QPF/HEAVY PRECIPITATION FORECAST.
STRONG LOW LEVEL JET INTO THE FRONT AS DEPICTED BY MODEL OF
CHOICE...THE ETA...WOULD SUPPORT CONTINUATION OF MCS EVEN THOUGH
UPPER WAVE MOVING THROUGH TONIGHT IS NOT NEARLY AS STRONG AS
LAST NIGHTS.

WILL ISSUE FLASH FLOOD WATCH ALL CWA INTO TUESDAY FORENOON DUE TO
EXPECTED ARRIVAL OF MCS A LITTLE LATER THAN LAST NIGHT...PROBABLY
TOWARD ERN COUNTIES BY 12Z.

BEYOND 18Z TOMORROW...EXPECT LITTLE IN THE WAY OF PCPN AS CAPPING
TAKES OVER AND WAVES REMAIN NORTHWEST OF CWA. ONLY FLY IN THE
OINTMENT IS CONVECTIVE FORECAST MOVEMENT IS NEARLY DUE SOUTH BY 12Z
WEDNESDAY...THUS ANY STRONG CONVECTION TO OUR NORTH COULD BE
APPROACHING IN SPITE OF STRONG CAP WEDNESDAY FORENOON.

.TOP...FLASH FLOOD WATCH TONIGHT AND TUESDAY FORENOON ALL OF CWA OR
NORTHEAST OF A LINE FROM CONCORDIA THROUGH ABILENE AND EMPORIA TO
GARNETT.
