EXACT EVOLUTION OF CONVECTION THIS MORNING WILL HAVE MAJOR IMPACT CONCERNING BOUNDARIES FOR REDEVELOPMENT THIS AFTERNOON AND EVENING. FOR NOW HAVE TRENDED MORE WITH THE NAM WHICH WILL FOCUS STORMS FROM SOUTHWEST/WESTERN NORTH TEXAS THROUGH CENTRAL AND NORTH CENTRAL OKLAHOMA. BY THURSDAY UPPER LOW WILL BECOME NEARLY STATIONARY OVER THE NORTHERN PLAINS BEFORE MOVING SOUTHEAST LATE FRIDAY INTO SATURDAY. THEREFORE THE FRONT WILL LIKELY LIFT NORTHWARD INTO THE CENTRAL PLAINS ON THURSDAY AND FOCUS MORE ORGANIZED CONVECTION ACROSS THIS REGION.
