DISCUSSION...  
SCATTERED SHOWERS ARE SEEN ACROSS THE FORECAST AREA THIS  
AFTERNOON. NO SEVERE STORMS, IN FACT SO FAR NO LIGHTNING.  
TEMPERATURES ARE MAINLY IN THE 60S, SO INSTABILITY MAY BE LACKING  
FOR THE LIGHTNING ASPECT.  
 
WILL CONTINUE THE FLASH FLOOD WATCH FOR THE LA PARISHES THROUGH  
TOMORROW AFTERNOON. THERE WILL BE ONE ROUND OF RAIN WITH EMBEDDED  
THUNDERSTORMS STARTING NOW THROUGH THE EVENING, TAPERING OFF AS WE  
GET CLOSE TO DAYBREAK ON SATURDAY.  
 
ANOTHER ROUND OF RAIN WITH EMBEDDED THUNDERSTORMS IS EXPECTED TO  
DEVELOP DURING THE DAY ON SATURDAY AS ANOTHER MID LEVEL SHORTWAVE  
MOVES WEST TO EAST ACROSS THE COAST. THIS ACTIVITY WILL TAPER OFF  
SATURDAY NIGHT.  
 
THE POPS STAY LOW MONDAY THROUGH THURSDAY. ANOTHER SHORTWAVE DOES  
MOVE ACROSS OUR AREA ON TUESDAY, BUT SO FAR MODELS HAVE BEEN  
HESITANT TO ADD PRECIP. IT COULD BE AN OVERRUNNING PRECIP EVENT,  
SO WILL MONITOR AS WE GET CLOSER TO THAT TIME FRAME.  
 
OTHERWISE, THE NEXT RAIN MAKER STARTS THURSDAY NIGHT INTO FRIDAY  
NEXT WEEK. THAT FAR OUT RELIABILITY IS ON THE LOW SIDE FOR  
SPECIFICS. STAY TUNED AS WE GET CLOSER TO SEE HOW IT PANS OUT.  
 
TEMPERATURES-WISE WE WILL STAY ON THE COOL SIDE FOR MUCH OF THE  
PERIOD.  
 
MARINE...  
WINDS AND SEAS WILL INCREASE BEHIND THE FRONT, STARTING AROUND  
DAYBREAK ON SATURDAY. A SMALL CRAFT ADVISORY IS IN PLACE. CONDITIONS  
SHOULD IMPROVE BY SUNDAY MORNING.
