FPUS3 KOKC 092026 AFDOKC AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 325 PM CDT TUE JUN 9 1998 SEVERE STORMS ARE DEVELOPING RAPIDLY IN THE SOUTHWEST CORNER OF THE FORECAST AREA. WE EXPECT CONTINUED DEVELOPMENT THROUGH THE EVENING...ESPECIALLY ALONG AND NEAR THE WEAKENING FRONTAL SYSTEM STRETCHED FROM NEAR STILLWATER TO ALTUS. UPPER FLOW IS ROUGHLY PARALLEL TO THE FRONTAL BOUNDARY WHICH SUGGESTS THE POSSIBILITY OF TRAINING STORMS. HAVE CONSIDERED THE POSSIBILITY OF A FLASH FLOOD WATCH...BUT AM NOT QUITE SATISFIED THAT WE CAN REACH GUIDANCE LEVELS OVER A WIDESPREAD AREA TONIGHT. FLOOD POTENTIAL APPEARS HIGHER TOMORROW EVENING...ONCE THE GROUND IS MORE SATURATED AFTER THE STORMS TONIGHT. ALTHOUGH THE MODELS DEVELOP AN UPPER RIDGE OVER US TONIGHT...IT APPEARS THAT SHORT WAVES WILL CONTINUE TO RIDE OVER THE RIDGE AND WILL LIKELY ADD SOME SUPPORT FOR CONVECTION FROM TIME TO TIME. MORE IMPORTANTLY...LEFTOVER BOUNDARIES FROM DAILY CONVECTION WILL PROVIDE SEEMINGLY RANDOM FAVORED AREAS FOR MORE CONVECTION. AM GUESSING THAT THE MAIN BOUNDARY TOMORROW WILL BE THE SOUTHERN OUTFLOW FROM THE STORMS TONIGHT. SO HAVE PLACED HIGHEST POPS IN SOUTH FOR TOMORROW. AFTER THAT...POPS ARE MORE UNIFORM. MOS TEMPERATURES ARE MOSTLY QUITE REASONABLE AND HAVE STRAYED LITTLE FROM THEM. INCREASING MOISTURE ASSOCIATED WITH RETURN TO SOUTHERLY LOW LEVEL FLOW SHOULD KEEP MINIMUM TEMPERATURES FAIRLY WARM FOR QUITE A WHILE. HAVE MADE A MINOR CHANGE TO THE EXTENDED PERIODS. MRF SUGGESTS ELEVATED CHANCES FOR PRECIPITATION ON SATURDAY...SO UPPED THE POPS FOR THAT DAY SLIGHTLY. COORD TUL.
