AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
232 AM CDT TUE APR 3 2007

.DISCUSSION...

OUTFLOW FROM CONVECTION IN NEBRASKA PUSHING SOUTHWARD ACROSS THE
CWA. SFC ANALYSIS SHOWS MAIN FRONT OUT WEST FROM HILL CITY
SOUTHWARD...WITH WV IMAGERY BRINGING MAIN SHORTWAVE PUNCH INTO
WESTERN NEBRASKA ATTM.

MUCH INSTABILITY EXISTS ALOFT...HOWEVER CAP IS STRONG AND HOLDING
AT THIS TIME. SOUTHWESTERLY LLJ OF 60 KTS OVER THE AREA NOSING INTO
IOWA...WHILE 60 DEGREE DEWPOINTS STREAM NORTHWARD. COLD POOL ALOFT WITH
UPPER LOW STILL BACK WEST CLOSER TO MAIN FRONT. THINKING AT THIS
TIME THAT WHILE OUTFLOW MAY NOT TRIGGER STORMS FARTHER
SOUTHWEST...MAY GET SOME ELEVATED CONVECTION ALONG THE MAIN FRONT
AS IT MOVES THROUGH. WITH INSTABILITY IN PLACE...SOME OF THE
STORMS COULD BE STRONG IF THE MAIN FRONT CAN PROVIDE ENOUGH LIFT
TO REALIZE AVAILABLE INSTABILITY. FRONT SHOULD BE INTO THE FAR SE
CWA AROUND THE NOON HOUR...AND HAVE LINGERED POPS INTO THE MORNING
HOURS ACROSS NORTHEAST AND EAST CENTRAL KANSAS. PRECIPITATION ENDS
THIS AFTERNOON ACROSS THE AREA AND COLD AIR MARCHES IN BEHIND.

REINFORCING SHORTWAVE MOVES THROUGH THE NORTHWESTERLY FLOW ON
THURSDAY...THEN ANOTHER FROM AROUND THE BACK OF THE GREAT LAKES
TROF ON FRIDAY. THESE FEATURES WILL KEEP OUR AREA COOLER THAN
NORMAL. HAVE EVEN ADDED A RAIN/SNOW MIX FOR SHORTWAVE EARLY THURSDAY
AND THURSDAY NIGHT. TEMPERATURES ARE VERY CLOSE TO FREEZING AS
EARLY AS TONIGHT...AND COOL SLIGHTLY MORE FOR WEDNESDAY NIGHT AND
THURSDAY NIGHT. CLOUDS MAY HELP MODERATE TEMPERATURES A FEW
DEGREES...BUT AGRICULTURAL INTERESTS SHOULD TAKE NOTE OF THE
ANTICIPATED COLD OVERNIGHT TEMPERATURES. MADE NO CHANGES BEYOND
FRIDAY. 67
