FORECAST: THUNDERSTORMS WILL CONTINUE DEVELOP ACROSS WESTERN MISSOURI EARLY THIS AFTERNOON WITH THE ENTIRE AREA SHIFTING TO THE EAST AS THE AFTERNOON PROGRESSES. THUNDERSTORMS MAY GROW STRONG ENOUGH TO PRODUCE SEVERE WEATHER...MAINLY IN AREAS NORTH AND EAST OF A LINE FROM ST. JOSEPH TO RICHMOND AND CLINTON MISSOURI. THESE STORMS MAY PRODUCE DAMAGING WINDS...WITH ISOLATED TORNADOES POSSIBLE. THE THUNDERSTORMS SHOULD BE ENDING IN WESTERN MISSOURI BY LATE AFTERNOON...AND IN CENTRAL MISSOURI BY THIS EVENING. SPOTTER ACTIVATION MAY BE NECESSARY. HEAVY RAIN WILL ALSO ACCOMPANY THESE THUNDERSTORMS...AND WITH THEIR NORTH NORTHEAST MOVEMENT...SOME AREAS MAY SEE A TRAINING AFFECT WHERE SEVERAL STORMS MOVE OVER THE SAME AREA. THIS MAY CAUSE SOME WATER PROBLEMS. DISCUSSION: LOW PRESSURE OVER NORTH CENTRAL KANSAS WILL BE LIFTING NORTHEAST INTO SOUTHEAST NEBRASKA THIS EVENING. A WARM FRONT LOCATED OVER NORTHERN MISSOURI WILL PROVIDE ONE FOCUS FOR THUNDERSTORMS THIS AFTERNOON...WHILE STRONG SOUTHERLY WINDS ACROSS WESTERN AND CENTRAL MISSOURI...TO THE SOUTH OF THE FRONT...WILL ALSO SUPPORT THUNDERSTORM DEVELOPMENT. DRIER AIR SHOULD BE PUSHING IN FROM THE WEST THIS AFTERNOON...WHICH WILL BRING AN END TO THE THUNDERSTORMS IN EASTERN KANSAS AND EXTREME WESTERN MISSOURI BY LATE AFTERNOON. PC
