EXCEPT FOR ONE SOLID BAND OF PRECIP MOVING ACROSS THE TOLEDO BEND REGION INTO NORTH CENTRAL LOUISIANA...RAINFALL HAS BEEN ISOLATED. WITH THE DEPRESSION WEAKENING AND CLOSING AROUND CENTER AFTER SUNSET...DO NOT THINK FLASH FLOOD WATCH IS NECESSARY.

AVN/ETA SUGGEST TUESDAY (DAY 3) FOR BEFORE FRONT REACHES NORTHWEST ZONES...AND LATE WEDNESDAY BEFORE IT REACHES SOUTHERN ZONES. SO WILL KEEP FAIRLY HIGH POPS AND QPF UNTIL THIS OLD FRONT FINALLY CREEPS ACROSS THE REGION. BY END OF WEEK...MAY FINALLY GET SOME DRIER AIR AND SLIGHTLY COOLER NIGHTTIME TEMPS. BUT AT THIS POINT...WOULD NOT BE SURPRISED IF FRONT WASHES OUT BEFORE BRINGING ANY SIGNIFICANT CHANGES. .PRELIMS...
