AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
403 PM CDT TUE MAY 1 2007

.DISCUSSION...

ACTIVE WEATHER THIS AFTERNOON PRECLUDES A DETAILED DISCUSSION. UPPER
LOW MOVING NORTH AND BRINGING ISOLATED INTENSE CONVECTION ALONG WEAK
FRONTAL BOUNDARY. THIS BOUNDARY SHOULD MOVE SLOWLY SOUTH THIS
EVENING WITH GRADUAL WEAKENING OF CONVECTION. BEST LIFT WITH UPPER
SYSTEM SHOULD CONTINUE TO MOVE NORTH OVERNIGHT BUT LOW LEVEL FOCUS
WILL BE LOST SO MORE WIDESPREAD AND STRONGER CONVECTION SHOULD
DIMINISH GREATLY AFTER MIDNIGHT.

AS UPPER LOW LIFTS NORTH ON WEDNESDAY...MORE GENERAL RAIN WILL
SPREAD NORTH AS WELL. HOWEVER THICK CLOUD COVER SHOULD PRECLUDE MUCH
IN THE WAY OF CONVECTION.

WITH CLOUD COVER HANGING TOUGH THROUGH WEDNESDAY...THERE SHOULD NOT
BE MUCH DIURNAL RANGE IN TEMPERATURES.

UPPER LOW WILL CONTINUE TO LIFT NORTH WEDNESDAY NIGHT AS A SECOND
SHORTWAVE DIGS INTO THE SOUTHERN ROCKIES. WILL CONTINUE WITH A
CHANCE FOR MORE SHOWERS AND THUNDERSTORMS AS THE LOW LIFTS NORTH
ACROSS THE AREA...ALTHOUGH THE CHANCES SHOULD DECREASE SOME LATE
THURSDAY INTO THURSDAY NIGHT AS THE EFFECTS OF THE SECOND WAVE PASS
MAINLY OFF TO THE SOUTH AND EAST OF THE CWA. WILL CONTINUE WITH A
DRY FCST FRIDAY NIGHT BEFORE AS YET ANOTHER WAVE WITHIN THE DIGGING
WESTERN TROUGH MOVES OUT INTO THE HIGH PLAINS SATURDAY. THE BETTER
CHANCES FOR THUNDERSTORMS OVER THE WEEKEND WILL BE OVER THE WESTERN
CWA CLOSER TO THE FRONTAL BOUNDARY. THIS WILL BE THE RULE ON INTO
EARLY NEXT WEEK AS THE FRONT GENERALLY REMAINS WEST OF THE CWA AS
UPPER RIDGE IN THE MS VALLEY HOLDS IN PLACE. DO NOT EXPECT THE FRONT
TO MAKE A STRONGER EASTWARD PUSH TOWARDS THE CWA UNTIL TUESDAY.

WITH THE DELAYED EASTWARD MOVEMENT OF THE FRONT...HAVE ALSO EDGED
HIGH TEMPERATURES UPWARD SLIGHTLY IN THE 80S SATURDAY THROUGH
MONDAY...THEN THE MIDDLE 70S AND LOWER 80S FOR TUESDAY.
