INCREASED CHANCE OF RAIN FOR AREA NORTHWEST OF BATON ROUGE AND FOR MS COAST. OTHERWISE...LEFT REMAINDER OF ZONES AND GRIDS ALONE FOR TONIGHT. UPPER LEVEL TROUGH APPROACH AREA FROM NORTHWEST WAS THE PRIMARY REASON. LATE BLOOMING THUNDERSTORMS ARE MOVING SOUTH INTO MS COASTAL COUNTIES. .PREVIOUS DISCUSSION... LATE AFTERNOON CONVECTION IS LIKELY TO PERSIST INTO THE EVENING AGAIN. THE MAIN DIFFERENCE TODAY IS HIGH CLOUD DEBRIS HAS KEPT TEMPERATURES AND INSTABILITY DOWN IN SOME AREAS.
