.SHORT TERM...TONIGHT AND TUESDAY.  ATTENTION IS
THUNDERSTORMS...ONGOING AND LATER DEVELOPING.  MORNING MCS PRODUCED
RAINFALL AMOUNTS ON AVERAGE OF ONE TENTH TO NEAR ONE HALF INCH
ACROSS MUCH OF THE CWA.  CONVECTION REMAINS ONGOING IN NORTH CENTRAL
KANSAS AND ADDITIONAL ACTIVITY HAS DEVELOPED ALONG OUTFLOW
BOUNDARIES IN OUR EASTERN CWA...AIDED BY INCREASING INSOLATION.

MAIN FOCUS THOUGH IS ON THE NEXT ROUND OF THUNDERSTORMS LATER THIS
AFTERNOON AND EVENING.  SURFACE TROUGH OR WEAK COLD FRONT WAS
ORIENTED FROM KANW TO KAIA AND KSNY AS OF 18Z.  MOISTURE AXIS WAS
LOCATED ACROSS CENTRAL AND EASTERN NEBRASKA AND KANSAS.  LAPS DATA

J/KG ALONG THE BOUNDARY IN WESTERN NEBRASKA...WITH LITTLE CIN.
VISIBLE SATELLITE IMAGERY ALSO SHOWS A LINE OF CUMULUS DEVELOPING
AS WELL...KUEX HAS SHOWN DEVELOPMENT NEAR BROWNLEE IN CHERRY
COUNTY.  ALL INDICATIONS SHOW THAT THIS WILL LIKELY BE THE AREA OF
CONTINUED INITIATION IN THE NEXT FEW HOURS...WITH THUNDERSTORMS
EXPECTED TO ORGANIZE AND MOVE SOUTHEAST THROUGH OUR CWA THIS
EVENING.  THE FRONTAL BOUNDARY SHOULD MAKE A BETTER PUSH SOUTHEAST
SHORTLY AS ENERGY ASSOCIATED WITH UPPER LOW IN SASKATCHEWAN PUSHES
FURTHER SOUTHEAST INTO SOUTH DAKOTA.  SHEAR IS DECENT FOR STORM
ORGANIZATION...WITH ENHANCEMENT BOTH ALONG APPROACHING AND RESIDUAL
BOUNDARIES.  EXPECT PRIMARY HAZARDS WILL BE DAMAGING WIND AND LARGE
HAIL.  LOWER LCL HEIGHTS...TEMP DEWPOINT SPREADS...AND MOISTURE
CONVERGENT AREA IS IN OUR SOUTHERN ZONES WILL ALSO BE FAVORABLE FOR
STORMS AS ANOTHER BOUNDARY STRETCHES ACROSS CENTRAL KANSAS.  THIS
AREA IS IN SPC MODERATE RISK OUTLOOK. CANNOT COMPLETE RULE OUT
TORNADIC DEVELOP...HOWEVER WIND...HAIL AND LOCALLY HEAVY RAINFALL
EXPECTED TO BE THE MAIN HAZARDS.

THE COOL FRONTAL BOUNDARY PUSHES THROUGH TONIGHT AND PRECIPITATION
WILL WIND DOWN AFTER MIDNIGHT.  SURFACE HIGH PRESSURE BUILDS IN ON
TUESDAY AND HEIGHTS RISE AND TEMPERATURES MODERATE AGAIN.  IN THE
DRIER AIRMASS...AFTERNOON READINGS SHOULD STILL REACH INTO THE 80S.

.LONG TERM...00Z WEDNESDAY THROUGH MONDAY. MAIN FORECAST CONCERNS

AN UPPER RIDGE AND SURFACE HIGH PRESSURE SYSTEM BUILD INTO THE REGION
TUESDAY NIGHT THROUGH THURSDAY. TEMPERATURES WILL BE QUITE WARM AS
850MB TEMPERATURES ARE EXPECTED TO BE AROUND 22 TO 26 DEG C.

BY THURSDAY A SHORT WAVE SLIDES ACROSS THE RIDGE AND WITH A
SURFACE LOW DEVELOPING TO THE WEST THERE IS A SLIGHT CHANCE FOR
SOME THUNDERSTORMS THURSDAY NIGHT. CONVECTION WILL LIKELY INITIATE
TO THE WEST ALONG THE FRONT...BUT WILL MOVE INTO FORECAST AREA
BEFORE THEY DISSIPATE.

THE RIDGE CONTINUES TO BREAK DOWN AS MORE SHORT WAVES MOVE INTO
THE AREA DURING THE WEEKEND. WITH EACH OF THE SHORT WAVES THERE IS
A SLIGHT CHANCE THAT THERE WOULD BE SOME SHOWERS OR THUNDERSTORMS.
THE BEST CHANCE WOULD BE SATURDAY NIGHT AS A COLD FRONT MOVES
THROUGH THE FORECAST AREA. AFTER THE COLD FRONT MOVES
THROUGH...COOLER TEMPERATURES ARE EXPECTED FOR THE AREA.
