PREV DISCUSSION... /ISSUED 303 AM CDT THU SEP 29 2011/

DISCUSSION...PERSISTENT CLUSTER OF STORMS OVER LOWER ACADIANA HAVE
BEEN SLOWLY DISSIPATING DURING THE OVERNIGHT HOURS.  SCATTERED TO
NUMEROUS STORMS HAD DEVELOPED ON WEDNESDAY EVENING ACROSS MUCH OF
SOUTHWEST LOUISIANA BUT DISSIPATED DURING THE EVENING.  MAIN
FORECAST ISSUE WILL BE DETERMINING THE POSITION OF QUASI-STATIONARY
BOUNDARY ESPECIALLY LATER TODAY.  FOR NOW...WILL FORECAST LOW CHANCE
POPS FOR AREA MOST OF AREA TODAY...SLIGHTLY HIGHER POPS OVER LOWER
ACADIANA.  MODELS ARE IN CONSENSUS BRINGING A SECOND FRONT THROUGH
THE AREA ON FRIDAY.  THIS WILL BRING DRIER AIR TO THE REGION
BEGINNING FRIDAY WITH SEASONABLY MILD DAYS AND COOL NIGHTS EXPECTED
THROUGH THE WEEKEND AND CONTINUING THROUGH EARLY NEXT WEEK. HIGH
PRESSURE OVER THE EASTERN U.S. WILL PERSIST THROUGH MUCH OF NEXT
WEEK. THIS WILL BRING A TRANSITION TO EASTERLY FLOW AND SLOW
MODERATION IN TEMPERATURES. MOISTURE RETURN WITH EASTERLY FLOW MAY
BECOME SIGNIFICANT ENOUGH FOR SOME SHOWERS BY THE MIDDLE OR LATER
PART OF NEXT WEEK. FOR NOW...WILL KEEP POPS OUT OF FORECAST FOR
NEXT WEEK.

OFFSHORE.  THINK SCEC CONDITIONS ARE LIKELY FROM FRIDAY INTO
SATURDAY WITH LOW END SCA CONDITIONS POSSIBLE. MODERATE EASTERLY
FLOW IS EXPECTED EARLY NEXT WEEK.
