AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
420 PM CDT WED MAY 11 2005

.DISCUSSION...

MAJOR CONCERNS ARE WEATHER WITH FRONTAL BOUNDARY IN AREA NEXT
SEVERAL DAYS.

FIRST ROUND OF CONVECTION TONIGHT COULD BRING MORE SEVERE WEATHER
WITH INSTABILITY FOCUSED ON OUTFLOW BOUNDARIES THIS EVENING AND
FRONTAL BOUNDARY AFTER MIDNIGHT. SOME BACKBUILDING TO OCCUR AS WELL
WITH REPEAT CELLS GIVING LOCALLY HEAVY RAIN.

MAIN FRONTAL BOUNDARY PUSHING TOWARD AREA AND STALLING TMRW NIGHT
MAY GIVE SOME FLOODING AS WELL. EXTENT AND SEVERITY OF ANY FLOODING
TMRW NIGHT MAY BE DICTATED BY PRECURSOR WEATHER TONIGHT. A FLOOD
WATCH MAY BE IN ORDER BY LATER TONIGHT OR TMRW MRNG.

MODELS FINALLY COMING TOGETHER WITH BEST LIFT AND ATTENDANT
CONVECTION PUSHING THROUGH AREA FRIDAY EVENING. APPEARS TO DRY AFTER
THAT WITH LITTLE OR NO CHANCE FOR PCPN INTO THE EXTENDED PD.

WILL CONTINUE TO FOLLOW THE EURO MODEL WITH TRENDS IN THE MID TERM.
NOT MUCH OF NOTE EXCEPT SOME PSBL CONVECTION ABOUT MIDWEEK NEXT
WEEK.

TEMPERATURES TRENDING DOWN AS FRONT APPROACHES. THEY ARE TRICKY TOO
WITH THESE CONVECTIVE EPISODES LOWERING POTENTIAL FOR MUCH WARMER
READINGS.

HAVE NOT MADE MANY CHANGES TO EARLIER EXTENDED NUMBERS SINCE TRENDS
APPEAR CONSISTENT WITH EURO MODEL TRENDS. HPC LIKES THIS MODEL AND I
WOULD TEND TO AGREE.
