AREAS GENERALLY NORTH OF A SAINT JOSEPH TO MACON LINE HAVE THE BEST CHANCE OF SEEING STRONG TO SEVERE THUNDERSTORMS. MODERATE INSTABILITY AND SUFFICIENT SHEAR SHOULD SUPPORT A FEW SEVERE THUNDERSTORMS AS A WEAK COLD FRONT ENTERS FAR NORTHWEST MISSOURI AND NORTHEAST KANSAS LATE THIS AFTERNOON. THE PRIMARY SEVERE THREATS WILL BE LARGE HAIL AND DAMAGING WINDS. IN ADDITION...CONSIDERABLE MOISTURE HAS MOVED INTO NORTHERN MISSOURI WITH PRECIPITABLE WATER CLOSE TO DOUBLE NORMAL VALUES. A MODERATELY STRONG SOUTHWESTERLY LOW LEVEL JET WILL FEED INTO THE BACK SIDE OF ANY ORGANIZED CONVECTION WHICH COULD LEAD TO BACK BUILDING OF STORMS AND CONVECTION MOVING REPEATEDLY OVER THE SAME AREAS. SINCE MUCH OF FAR NORTHEAST KANSAS AND NORTHERN MISSOURI RECEIVED VERY HEAVY RAIN SATURDAY NIGHT...THE GROUND IS NEARLY SATURATED SO MOST OF THE RAIN WHICH FALLS WILL QUICKLY RUN OFF AND COULD LEAD TO FLASH FLOODING. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY ANOTHER COLD FRONT AND STRONG UPPER LEVEL SYSTEM WILL MOVE INTO THE AREA THURSDAY AFTERNOON AND NIGHT WITH A BETTER CHANCE FOR THUNDERSTORMS. SEVERE WEATHER AND HEAVY RAINFALL ARE POSSIBLE. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED OVER NORTHERN MISSOURI LATE THIS AFTERNOON AND EVENING. NRR
