AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
301 PM CDT THU JUN 3 2010

.SYNOPSIS...
A BROAD UPPER LOW OVER EAST TEXAS WILL CONTINUE TO GENERATE
SHOWERS AND THUNDERSTORMS ACROSS THE AREA THIS EVENING. A TROUGH
APPROACHING AND CROSSING THE AREA FRI AND SAT WILL BRING A RENEWED
THREAT OF THUNDERSTORMS. BEHIND THE TROUGH ON SUNDAY WEAK RIDGING
WILL BEGIN TO BUILD IN ALLOWING FOR LIMITED CLEARING AND WARMING
TEMPERATURES.

&&

.SHORT TERM...
CONVECTION WILL SLOWLY TAPER THIS EVENING AS THE BAND THAT MOVED
THROUGH THE AREA TODAY EJECTS OUT TO THE NORTH. LINGERING CLOUDS
FROM THIS BAND WILL LIKELY REMAIN THROUGH THE NIGHT. THE UPPER LOW
OVER E TX THIS EVENING WILL PUSH INTO THE AREA SAT AS A TROF ALONG
THE JET PULLS THE LOW TO THE EAST. MODELS AGREE THAT THE APPROACH
AND PASSAGE OF THE TROF WILL BRING MORE INSTABILITY ACROSS THE
REGION...YIELDING CONTINUED CONVECTION DURING THE DAYTIME FRI THEN
DIMINISHING SOMEWHAT ON SAT. THE LATTER HALF OF THE WEEKEND WILL
BRING A WEAK RIDGE BUILDING OVER THE AREA YIELDING INCREASING
TEMPS. OVERALL LITTLE CHANGE WAS MADE TO THE ONGOING FORECAST. BFG

.LONG TERM...
FOR NEXT WEEK A WARMER DRIER PATTERN WILL PREVAIL AS A WEAK RIDGE
SETS UP OVER THE AREA. MODELS DIFFER ON THE LONG RANGE SOLN WITH
THE GFS BRINGING A TOUGH/FRONT INTO THE AREA AROUND THU. THE ECMWF
ON THE OTHER HAND CONTINUES TO BE THE FAVORED SOLN WITH A MORE
ZONAL PATTERN ACROSS THE NORTHERN PORTIONS OF THE US. THIS PATTERN
WILL MAINTAIN A WARMER DRIER PATTERN FOR THE WEEK. THOUGH A ECWMF
IN THE PREFERRED MODEL FOR THE LONG RANGE...WILL STILL LEAVE SOME
KIND OF POPS IN AS CONFDC IS LOW DUE TO MODEL RUN DIFFERENCES. BFG

&&

.AVIATION...
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO AFFECT THE
TERMINALS THIS EVENING...WITH VFR CONDITIONS OUTSIDE OF THESE STORMS
AND MVFR OR EVEN IFR CONDITIONS WITHIN THEM. LATEST GFS AND NAM
CONTINUE TO INDICATE A SURFACE LOW VERY SLOWLY TREKKING EASTWARD
FROM THE SABINE RIVER FRIDAY MORNING...WHICH WILL RESULT IN ANOTHER
ROUND OF SHRA AND TSRA ACROSS THE AREA FRIDAY. 95/DM

&&

.MARINE...
SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE OVER
THE COASTAL WATERS THIS EVENING...BUT SHOULD TAPER OFF A BIT AFTER
SUNSET. LATEST MODEL GUIDANCE CONTINUES TO INDICATE THAT A SLOW
MOVING LOW WILL TREK EASTWARD ACROSS LOUISIANA OVER THE NEXT DAY OR
TWO. THIS WILL CONTINUE TO RESULT IN ONSHORE FLOW AND A CHANCE OF
SHOWERS AND THUNDERSTORMS OVER THE WATERS. BASED ON CURRENT
CONDITIONS...HAVE INCREASED WIND SPEEDS FOR THE FIRST FEW PERIODS.
HAVE ALSO ADJUSTED WIND DIRECTION BASED ON THE FORECAST TRACK OF THE
LOW...NEARLY ALL COASTAL WATERS WILL MAINTAIN A SOUTHERLY COMPONENT
TO THE WIND THROUGH THE FORECAST PERIOD. 95/DM
