AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
3 PM CDT FRI APR 20 2001

THUNDERSTORM CHANCES ARE MAIN FORECAST CONCERN THROUGH THE WEEKEND.

LATEST SATELLITE SHOWING EXTENSIVE MID AND HIGH CLOUDS CONTINUING
ACROSS THE REGION...WHICH MAY THIN OUT LATER...BUT SHOULD PERSIST
THROUGH MUCH OF THE NIGHT. WARM FRONT HAS LIFTED NORTH INTO SOUTHERN
NEBRASKA WITH DRYLINE EXTENDING SOUTHWESTWARD THROUGH WESTCENTRAL
KANSAS.

INITIAL SHORTWAVE MOVING ACROSS THE AREA WILL BE REPLACED BY
STRONGER SHORTWAVE NOW MOVING THROUGH THE CENTRAL ROCKIES. VERY
STRONG CAP IN PLACE ALTHOUGH BETTER POTENTIAL FOR CAP BEING BROKE
LATER IN THE NIGHT AS WAVE LIFTS OUT AND TEMPORARY BACKING FLOW
ALLOWS DEEPER LOW LEVEL MOISTURE TO RETURN. SOME POTENTIAL FOR
CONVECTION TO DEVELOP EARLIER AHEAD OF DRYLINE. WILL KEEP POPS GOING
ALL AREAS WITH HIGHER POPS AND BETTER SEVERE POTENTIAL ACROSS THE
NORTH AND NORTHCENTRAL.

AS SFC LOW MOVES OFF TO THE NORTHEAST EXPECT FRONT TO MOVE INTO THE
CWA FROM WEST OVERNIGHT BUT NOT MAKE IT MUCH FURTHER SOUTHEAST THAN
THE EASTCENTRAL AREAS. WOULD EXPECT THE POSSIBILITY OF MORE
CONVECTION TO REDEVELOP ALONG AND NORTH OF BOUNDARY IN THE AFTERNOON
OVER SOUTHERN 2/3 OF THE CWA WITH A BETTER CHANCE INTO THE NIGHT AS
NEXT SHORTWAVE EMERGES FROM THE HIGH PLAINS. WILL INCREASE POPS
ACROSS THE CWA SATURDAY NIGHT TO AROUND 50 PERCENT.

MAIN UPPER LOW WILL BEGIN TO APPROACH THE AREA SUNDAY INTO SUNDAY
NIGHT. EXTENSIVE CLOUDS AND SOME PRECIP WILL LIKELY HELP TO LIMIT
HIGHS TEMPS. WILL GO WITH COMPROMISE OF COOLER FWC SATURDAY AND
WARMER MAV/FAN FOR SUNDAY. WILL ALSO GO WITH LIKELY POPS SUNDAY
NIGHT AS MAING UPPER LEVEL PUSH ENTERS THE CWA FROM WEST TO EAST.

.TOP...NONE.
