AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OKLAHOMA 900 PM CDT FRI APR 23 2004 GOING FORECAST LOOKS GOOD WITH VERY HIGH POTENTIAL FOR WIDESPREAD FLASH FLOODING OVER THE NEXT 24 HOURS. SHOWERS AND THUNDERSTORMS WILL CONTINUE TO INCREASE IN AREAL COVERAGE TONIGHT AS LIFT INCREASES AHEAD OF THE APPROACHING UPPER SYSTEM. WIDESPREAD 1-3 INCH RAINFALL AMOUNTS WILL OCCUR BY THIS TIME TOMORROW WITH LOCAL AMOUNTS OVER 5 INCHES. ELEVATED INSTABILITY IS MARGINAL SO ONLY EXPECT A FEW ISOLATED SEVERE STORMS TONIGHT WITH MAINLY LARGE HAIL. WHAT LITTLE ELEVATED INSTABILITY THERE IS BECOMES EVEN LESS BY MORNING SO STORM INTENSITIES SHOULD TREND DOWNWARD AFTER THE CURRENT WATCH EXPIRATION TIME BUT FLASH FLOOD POTENTIAL WILL BE INCREASING GREATLY BY THAT TIME.
