THIS TROUGH WILL TRIGGER SCATTERED SHOWERS AND TSTORMS ONCE AGAIN TODAY AS PW/S REMAIN ABOVE 1.00 INCH AND AFTERNOON INSTABILITY REMAINS HIGH. THE MAIN FOCUS WILL BE ERN ZONES WHERE LOCALLY HEAVY RAINS ARE LIKELY IN AREAS. WILL NOT ISSUE A FLOOD WATCH AS HEAVY SHOWERS WILL LIKELY MOVE QUICKER COMPARED TO PAST EVENTS. HOWEVER...
