AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
240 PM CDT SUN MAY 6 2001

MAIN PROBLEMS ARE THUNDERSTORMS IN THE EAST THIS EVENING, THEN SKY
COVER ASSOCIATED WITH WEAK SYSTEMS MOVING THROUGH IN NORTHWEST FLOW.

CAPES OF 1000 TO 2000 AND RELATIVELY WEAK VERTICAL WIND SHEAR HAS
LEAD TO DEVELOPMENT OF WIDELY SCATTERED STRONG STORMS IN CONFLUENCE
ZONE ALONG THE KANSAS TURNPIKE.  GIVEN WIND SHEAR AND OBSERVED STORM
STRUCTURE, INDICATES ONLY LOOSE ORGANIZATION TO STORMS.  LOW
FREEZING LEVELS PUT VIL OF THE DAY IN THE LOWER 40S.  EXPECT WIDELY
SCATTERED STRONG TO SEVERE STORMS WITH DIME TO NICKEL SIZE HAIL TO
CONTINUE INTO THE EVENING HOURS ACROSS FAR EASTERN KANSAS AS
CONFLUENCE AXIS MOVES SLOWLY EAST.

SKIES SHOULD CLEAR LATER TONIGHT AND COOLER TEMPERATURES WILL BE
EMPHASIZED.  AFTER THAT, WEAK WAVES IN NORTHWEST FLOW BRING
MID-LEVEL MOISTURE WITH THEM BOTH MONDAY AND TUESDAY.  PRECIP
CHANCES LOOK NIL, BUT ENOUGH TO INCREASE CLOUD WORDING, AND TO GO A
LITTLE BELOW NGM GUIDANCE TEMPS FOR HIGHS.
