AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OK 818 PM CDT WED JUL 4 2007 .UPDATE... SHOWERS AND THUNDERSTORMS DEVELOPED ALONG A NEARLY STATIONARY COLD FRONT ACROSS KANSAS THIS EVENING. THE ACTIVITY HAS SLOWLY BEEN PUSHING SOUTH...AND LOOKS TO MOVE INTO NORTHEAST OKLAHOMA BY 9 PM. MCV ACROSS SOUTH CENTRAL KANSAS...AS SEEN IN RADAR IMAGERY...HAS AIDED IN THE FASTER MOVING CONVECTION ACROSS NORTHWEST/NORTH CENTRAL OKLAHOMA. WHILE SHOWERS AND THUNDERSTORMS WILL LIKELY AFFECT THE FAR NORTHERN PORTION OF THE FORECAST AREA...EXPECT THE BULK TO REMAIN JUST WEST...CLOSER TO THE MCV. WITH THE LOSS OF DAYTIME HEATING...THE STORMS MOVING OUT OF KANSAS SHOULD DIMINISH IN INTENSITY AND COVERAGE THIS EVENING. HOWEVER...DUE TO THE SLOW MOVEMENT...WILL HAVE TO KEEP AN EYE ON LOCALLY HEAVY RAINFALL. HAVE ADJUSTED POPS FOR TONIGHT TO REFLECT THIS LATEST THINKING. ISOLATED SHOWERS AND THUNDERSTORMS DEVELOPED DURING THE HEAT OF THE AFTERNOON ACROSS EASTERN OKLAHOMA AND NORTHWEST ARKANSAS...WITH A FEW STORMS STILL REMAINING AT 8 PM.

MORE POTENT TSRA ALONG FRONTAL BOUNDARY IN KANSAS...AIDED BY WESTERN KANSAS MCV LESS BENIGN. CURRENT THINKING IS KANSAS ACTION WILL STAY WEST OR NORTH OF MOST OF EASTERN OKLAHOMA. RAISED POPS ALONG IMMEDIATE KANSAS BORDER. IF HEAVY RAIN DOES MATERIALIZE IN FAR NORTHEAST OKLAHOMA..A FLOOD WATCH MAY BECOME NECESSARY. WEST-EAST SURFACE BOUNDARY DRIFTS SOUTH INTO CWA THURSDAY. HIGHER MAV POPS JUSTIFIED OVER LOWER MET GIVEN LOW 70 DEWPOINTS. ATMOSPHERE EXTREMELY WELL PRIMED AND ALMOST ANY AREA CONVERGENCE WILL PRODUCE THUNDERSTORMS.
