-- Changed Discussion --
UPPER LEVEL RIDGE OF HIGH PRESSURE OVER THE SOUTHWESTERN STATES AND AN UPPER LEVEL TROUGH WAS BEGINNING TO DIG SOUTHEAST TOWARDS THE MID ATLANTIC COAST AHEAD OF A SUMMER COLD FRONT MOVING SE TOWARD THE MID MS VALLEY THIS EVENING. A COMPLEX OF THUNDERSTORMS WAS ALSO MOVING SOUTHEAST AROUND THE EDGE OF THE UPPER HIGH INTO THE OHIO VALLEY. THE STORMS ARE NOW CROSSING THE OHIO RIVER WEST OF LOUISVILLE AND SHOULD REACH THE FORECAST AREA AROUND 6Z-9Z SUNDAY. STRONG WINDS ALOFT AND INSTABILITY FROM HOT TEMPERATURES EARLIER TODAY TO OUR NW WILL FUEL THESE STORMS FOR SEVERAL MORE HOURS WITH DAMAGING WINDS AND POSSIBLE HAIL LATER TONIGHT ACROSS THE NORTHERN PARTS OF THE FORECAST AREA. THERE IS SOME QUESTION OF HOW FAR THE STORMS WILL GET BEFORE DECREASING IN INTENSITY. HAVE SLOWED THE TIMING SOME BUT KEPT CHANCE POPS NORTHERN SECTIONS. I WILL ADJUST HAZARDOUS WEATHER OUTLOOK TO REFLECT CHANCE OF STORMS FARTHER WEST IN THE OVERNIGHT PERIOD.
