AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
301 PM CDT TUE APR 24 2007

.DISCUSSION...

PRECIPITATION CHANCES TONIGHT AND WEDNESDAY ARE THE MAIN FORECAST
CHALLENGES THROUGH WEDNESDAY AFTERNOON.

UPPER LOW AND SURFACE MAKING SLOW EASTWARD PROGRESS ACROSS
SOUTHERN COLORADO EARLY THIS AFTERNOON. DRY PUNCH HAS PUSHED A
DRYLINE/PACIFIC BOUNDARY INTO SOUTH CENTRAL KANSAS AND WEST CENTRAL
OKLAHOMA WITH A WARM/STATIONARY FRONT FROM WEST CENTRAL KANSAS
NORTHEAST TO NEAR CNK AND STJ...ENHANCED BY PERSISTENT ELEVATED
CONVECTION FROM LAST NIGHT THROUGH EARLY AFTERNOON. BOUNDARY HAS
MADE ITS WAY SOUTH ACROSS HIGHWAY 36 FROM THIS RAIN COOLED AIR.
CONVECTION THAT FIRED IN THE MOIST PLUME AHEAD OF THE DRYLINE HAS
REACHED NORTH CENTRAL KANSAS...WITH LESS IMPRESSIVE DEVELOPMENT TO
THE SOUTH.

SEVERE WEATHER CONCERNS CONTINUE FOR THE AFTERNOON AND AT LEAST
EVENING HOURS WITH UPPER LEVELS CONTINUING TO DESTABILIZE WITH A
WEAKER WAVE APPEARING TO WRAP ACROSS THE SOUTHWEST QUADRANT OF THE
UPPER LOW AT MID DAY. ALTHOUGH THE DRYLINE/PACIFIC FRONT MAY LOSE
ITS IDENTITY FOR A LOW LEVEL FOCUSING MECHANISM THIS
EVENING...STORMS SHOULD BE ONGOING IN AND NEAR THE AREA AT ISSUANCE
TIME...AND PERSIST BY AID OF DEEP MOISTURE AND DIFFLUENCE ALOFT.
INSTABILITY WILL SLOWLY DIMINISH WITH LOSS OF DAYTIME HEATING...BUT
SOME WILL PERSIST ALOFT. LOW LEVEL WINDS SHOULD BACK SOMEWHAT THIS
EVENING AS THE SURFACE LOW MOVES ACROSS NORTHERN OKLAHOMA AND KEEP
SOME THREAT OF TORNADOES IN PLACE FOR AT LEAST SEVERAL HOURS.
PRECIPITATION CONCERNS SLOWLY TRANSITION TO A LESS SEVERE NATURE ON
THROUGH WEDNESDAY AFTERNOON. MODELS DIFFER ON PLACEMENT OF BEST RAIN
CHANCES...SOMEWHAT TIED TO THE HANDLING OF THE CURRENT SOUTHWEST
QUADRANT FEATURE AND ITS AFFECT ON THE UPPER LOW. STILL...DEEP
MOISTURE WILL REMAIN WITH SOME Q-G FORCING ALOFT LOW LEVEL MOISTURE
CONVERGENCE AND FRONTOGENESIS FOR MOST PLACES TO SEE SOME MORE RAIN.
LOW LEVEL TEMPS MAY BE WARM ENOUGH FOR A FEW SEVERE STORMS IN EAST
CENTRAL KANSAS...BUT THREAT LOOKS MUCH LOWER THAN THAT OF THIS
EVENING. DID NOT CHANGE TEMPERATURES MUCH FOR TONIGHT OR WEDNESDAY
WITH PRECIPITATION AND CLOUD COVER KEEPING THINGS COOL FOR THE
AFTERNOON.

UPPER TROUGH WILL CONTINUE TO PROGRESS EAST WEDNESDAY NIGHT ACROSS
EASTERN KANSAS. EXPECT SHOWERS IN THE DEFORMATION AXIS TO THE
NORTHWEST OF THE UPPER LOW THROUGH THE NIGHT. SOME ISOLATED
THUNDERSTORMS WILL ALSO BE POSSIBLE THROUGH THE NIGHT SOUTHEAST OF
THE TURNPIKE.

THURSDAY DEPENDING ON THE FORWARD SPEED OF THE UPPER LOW INTO
MISSOURI THE 850-500 MB TROUGH AXIS MOVES EAST OF THE CWA BY 18Z
THURSDAY AND HAVE EXPANDED POPS SLIGHTLY WEST FROM PRIOR FORECAST
AND DROP PRECIPITATION FOR THE AFTERNOON HOURS IN THE EASTERN CWA.

THE NEXT WAVE TO MOVE THROUGH ON FRIDAY MOVES A TROUGH QUICKLY
THROUGH THE MORNING AND AFTERNOON HOURS. BEST FORCING LOOKS TO BE
ACROSS SOUTHERN KANSAS AND INTO PARTS OF EAST CENTRAL DURING THE DAY
ON FRIDAY. WILL HOLD OFF FOR NOW ON INTRODUCING SMALL CHANCE OF
SHOWERS FRIDAY AFTERNOON. ECMWF AND CANADIAN GEM KEEP QPF TO THE
SOUTH OF THE CWA AS DOES THE GFS.

FORECAST BEYOND FRIDAY INTO NEXT TUESDAY BEARS SOME WATCHING FOR
EARLY NEXT WEEK AS MODELS DIFFER WITH THE PLACEMENT OF THE UPPER LOW
THAT MOVES EAST OUT OF THE ROCKIES. CONSENSUS WAS TO LEAN TOWARD THE
24/00Z RUN OF THE ECMWF WHICH PUTS A CLOSED LOW OVER NORTH TEXAS
WHILE THE GFS MOVES OUT A OPEN TROUGH ACROSS KANSAS ON TUESDAY. WITH
ENOUGH UNCERTAINTY WILL NOT INTRODUCE POPS AT THIS TIME.
TEMPERATURES WILL RECOVER FROM THE 60S ON FRIDAY TO THE LOWER 80S
FOR SUNDAY THROUGH TUESDAY.
