Hail in Kansas, April 30, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
323 PM CDT SUN APR 30 2006

.DISCUSSION...
FORECAST CONCERNS WILL DEAL WITH PRECIP CHANCES AND POSSIBLE
STRONG/SEVERE STORMS FOR THE NEXT FEW DAYS...FOLLOWED BY A COOL DOWN
FOR LATE IN THE WEEK.

TONIGHT
ANY PRECIP ACTIVITY FROM THIS AFTERNOON/EVENING SHOULD GRADUALLY END
ACROSS SOUTHERN AND SOUTHEAST KANSAS ONCE DAYTIME HEATING IS
LOST...AND UPPER LEVEL IMPULSE SHIFTS EAST OF KANSAS. A FEW STRONG
TO POSSIBLY SEVERE STORMS WITH HAIL AND GUSTY WINDS WILL BE POSSIBLE
OVER SOUTHERN/SOUTHEAST KANSAS THROUGH THE EVENING HRS.

MON-TUES
DAYTIME TEMPS SHOULD CONTINUE TO WARM UP THIS 48HR PERIOD WITH 70S
ON MONDAY AND LOWER 80S FOR TUESDAY. WATER VAPOR IMAGERY SHOWS A
COUPLE SHORT WAVES OFF TO OUR NORTHWEST. THE FIRST WAVE NOW MOVING
ACROSS THE ROCKIES WILL AFFECT KANSAS DURING THE DAY ON MONDAY.
VERTICAL MOTION IN THE MID-LEVELS WILL INCREASE AHEAD OF THIS WAVE
WHICH SHOULD SPARK OFF SOME AFTERNOON ACTIVITY OVER SOUTHERN AND
SOUTHEAST KANSAS. ONCE AGAIN A FEW STRONG TO POSSIBLY SEVERE STORMS
COULD MATERIALIZE...ESPECIALLY OVER SOUTHEAST KANSAS WHERE BETTER
INSTABILITY WILL RESIDE. MEANWHILE...NEXT DISTURBANCE VIA WATER
VAPOR IMAGERY IS CURRENTLY OVER THE EASTERN PACIFIC AND IS PROGGED
BY THE MODELS TO RACE EAST ACROSS THE NORTHERN PLAINS ON TUESDAY.
THIS WILL SEND A COLD FRONT SOUTHWARD INTO KANSAS SOMETIME TUESDAY
NIGHT WHICH IS FASTER THAN THE PREVIOUS 24HR MODEL RUN. WE WILL
MAINTAIN SLIGHT POPS FOR SOUTHERN KANSAS TUESDAY AFTERNOON IF A WEAK
BOUNDARY CAN AVOID BECOMING DIFFUSE. OTHERWISE...THE BETTER PRECIP
CHANCES SHOULD BE ALONG THE SYNOPTIC FRONT IN NEBRASKA WHICH WILL
THEN SLIDE INTO KANSAS LATER ON. MODELS SHOW A SIGNAL FOR POSSIBLE
MCS DEVELOPMENT TUESDAY NIGHT WITH MCS PROPAGATION TO THE
SOUTH/SOUTHEAST ACCORDING TO MID-LEVEL THICKNESS PATTERN AND
POSITION OF INSTABILITY AXIS. SEVERE WEATHER COULD BE A POSSIBILITY
ACROSS THE AREA TUESDAY NIGHT WITH THIS MCS...AND LATER SHIFTS WILL
CONTINUE TO MONITOR TRENDS.

WED
THE KEY FACTOR TO WATCH WILL BE THE POSITIONING OF THE FRONTAL
BOUNDARY FOR THIS PERIOD INTO THURSDAY AS MID-LEVEL FLOW BECOMES
MORE ZONAL AND PARALLELS THE LOW LEVEL BOUNDARY...THUS CAUSING THE
FRONT TO HANG UP SOMEWHERE ACROSS THE REGION. LATEST MODEL PROGS
HAVE THIS BOUNDARY PUSHING SOUTH OF THE AREA BUT CONFLUENT FLOW OVER
THE GREAT LAKES COULD ENHANCE JET DYNAMICS OVER KANSAS...AND WITH
THE LOW LEVEL BOUNDARY SOUTH OF THE KS/OK BORDER THIS COULD LEAD TO
A UNSETTLED WEATHER PATTERN. WITH THAT SAID WE WILL KEEP POPS GOING
THROUGHOUT THE PERIOD...BUT NOT EXPECTING IT TO RAIN THE ENTIRE
DAY/NIGHT TIME FRAME.

EXTENDED: THUR-SUN
STILL LOOKS LIKE COOLER TEMPS WILL HIT THE AREA FOR LATE NEXT WEEK
WITH CHANCES OF PRECIP STILL POSSIBLE ACROSS SOUTHERN KANSAS ON
THURSDAY.

THE FRONTAL BOUNDARY SHOULD BE SOUTH OF THE AREA ON THURSDAY WITH
TEMPS AROUND NORMAL. WE WILL STILL HOLD ON TO SOME PRECIP CHANCES AS
NEXT UPPER WAVE DROPS SOUTH ACROSS THE NORTHERN PLAINS...THUS
INCREASING MID-LEVEL WARM AIR ADVECTION AND UPWARD VERTICAL MOTION
FROM UPPER JET IN CLOSE PROXIMITY. OTHERWISE...DRY AND SLIGHTLY
COOLER CONDITIONS LOOK TO BE ON TAP FOR FRI/SAT WITH SURFACE HIGH
PRESSURE SETTLING OVER THE REGION. HEADING INTO DAY 7 MODELS SHOW
ANOTHER SYSTEM POSSIBLY TAKING SHAPE OVER THE WESTERN STATES. THIS
SYSTEM COULD AFFECT THE AREA LATE SUNDAY NIGHT OR EARLY NEXT WEEK.
