Area forecast discussion, May 6, 2:40 PM CDT, 2 hours 40 minutes before
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. .TOP...NONE GDP
