AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
1229 PM CDT WED MAY 26 2010

.DISCUSSION...
FOR THE 26/18Z TAF ISSUANCE.

&&

.AVIATION...
CURRENTLY VFR CONDITIONS ARE OCCURRING ACROSS THE AREA WITH CU
JUST BEGINNING TO BUILD UP. FOR THE REMAINDER OF THE
AFTERNOON...MOIST AND VERY UNSTABLE AIR MASS IN PLACE...SO WITH
DAYTIME HEATING CU SHOULD CONTINUE TO BUILD WITH ISOLATED SHOWERS
AND THUNDERSTORMS DEVELOPING. DUE TO THE ISOLATED NATURE OF THE
ACTIVITY WILL JUST MENTION VCSH OR VCTS FOR TAF SITES.

ACTIVITY THAT DOES DEVELOP WILL DISSIPATE IN THE EVENING WITH THE
LOSS OF DAYTIME HEATING. SOME PATCHY FOG WILL DEVELOP WITH MVFR
VISIBILITIES POSSIBLE DURING THE LATE OVERNIGHT UNTIL SHORTLY
AFTER SUNRISE THURSDAY.

.PREV DISCUSSION... /ISSUED 1036 AM CDT WED MAY 26 2010/

DISCUSSION...
WEAK RIDGING OVER THE REGION IS PRODUCING LIGHT WINDS WITH A WEAK
NORTHERLY COMPONENT. WITH THE EXCEPTION OF SOME MIDLEVEL
CLOUDS...SKIES ARE MOSTLY SUNNY ACRS THE AREA...AND THIS HAS
ALLOWED TEMPERATURES TO CLIMB INTO THE LOW TO MID 80S AS OF 10
AM. ANOTHER WARMER THAN NORMAL AFTN ON TAP WITH FCST HIGHS NEAR 90
STILL LOOKING GOOD. WITH SUFFICIENT SUNSHINE...A FEW LOCATIONS
COULD APPROACH THE MID 90S. HOWEVER...ANY CONVECTION THAT DEVELOPS
WILL LIMIT HEATING...AND AT THIS TIME...STILL EXPECT TO SEE SOME
SCATTERED SHOWERS OR THUNDERSTORMS DEVELOP BY MID AFTN. CURRENT
POPS LOOK FINE FOR NOW WITH BETTER CHANCES OVER ERN PORTIONS OF
THE AREA. NO UPDATE PLANNED FOR THIS MORNING. 24

PREV DISCUSSION... /ISSUED 546 AM CDT WED MAY 26 2010/

DISCUSSION...
WATER VAPOR SATELLITE IMAGERY/UPPER AIR ANALYSIS SHOWED A MID/UPPER
LOW OFF THE COAST OF THE CAROLINAS...A BROAD MEAN TROF OVER THE
WESTERN CONUS...AND A MEAN RIDGE STRETCHING FROM THE GREAT LAKES
TO THE NORTHWEST GULF COAST REGION.

AT THE SFC...HIGH PRESSURE EXTENDS FROM THE OHIO RIVER VALLEY TO
THE NORTHWEST GULF COAST REGION.

ASCERTAINING CONVECTIVE POTENTIAL AND INITIATION TODAY IS THE
PRIMARY NEAR TERM CHALLENGE...AND IT IS A DIFFICULT ONE. ACTIVITY
YESTERDAY AFTERNOON AND EVENING APPEARS TO HAVE BEEN INITIATED/SUSTAINED
VIA A COMBINATION OF OUTFLOW BOUNDARIES AND A SUBTLE VORT MAX THAT
TRANSLATED INTO THE AREA FROM SOUTHERN TEXAS. THIS FEATURE IS STILL
EVIDENT ON WATER VAPOR IMAGERY OVER SOUTH CENTRAL AND SE
LOUISIANA...BUT SHOULD BE EAST OF US AND A NON-FACTOR BY THIS
AFTERNOON. THERE IS ANOTHER APPARENT FEATURE JUST CROSSING THE RIO
GRANDE INTO SOUTH CENTRAL TEXAS...WHICH MAY SERVE AS ONE TRIGGER
WHILE PERTURBATIONS RIDING AROUND THE MID/UPPER LOW TO THE EAST
AND/OR OUTFLOW BOUNDARIES SERVE AS OTHERS. AREA FORECAST SOUNDINGS
INDICATE MODEST INSTABILITY...LITTLE INHIBITION...AND DEEP
MOISTURE WILL BE IN PLACE BY THIS AFTERNOON...SO ANY OF THE ABOVE
MENTIONED LIFTING MECHANISMS WOULD BE SUFFICIENT TO GET CONVECTION
GOING.

IN TERMS OF CONVECTIVE CHARACTERISTICS...RELATIVELY SLOW MOVING...SHORT
LIVED...AND OUTFLOW DOMINANT CELLS ARE EXPECTED.

BEYOND TODAY...THE MEAN RIDGE IS FORECAST TO RETROGRADE WESTWARD
AND AMPLIFY...WHILE A DEEP MEAN TROF DEVELOPS OVER THE EASTERN
CONUS. FELT FAIRLY GOOD ABOUT LEAVING SMALL POPS IN THE FORECAST
THURSDAY AND FRIDAY...AS MODELS LEAVE DECENT MOISTURE IN PLACE AND
CONTINUE TO SHOW SUBTLE PIECES OF ENERGY TRANSLATING THROUGH THE
NORTHERLY FLOW ALOFT.

ON SATURDAY...A MORE SIGNIFICANT SHORTWAVE...ACCOMPANIED BY A
40-50KT JET MAX...IS FORECAST TO DROP INTO THE NORTH CENTRAL GULF
COAST REGION. ON THE PLUS SIDE...IN COMBINATION WITH A JET MAX
TRANSLATING THROUGH THE SUBTROPICAL JET TO THE SOUTH...THIS WILL
RESULT IN GENERALLY FAVORABLE JET SUPPORT FOR CONVECTION. ON THE
NEGATIVE SIDE...THE NAM AND THE GLOBAL MODELS SHOW MUCH DRIER AIR
WRAPPING INTO THE AREA. THE ECMWF IS LESS AGGRESSIVE WITH THE DRY
AIR...BUT EVEN IT IS FAIRLY PALTRY WITH THE QPF IT GENERATES. FOR
THE TIME BEING...HAVE LEFT A SLIGHT CHANCE IN THE FORECAST...THOUGH
THIS COULD PROVE GENEROUS.

NO SIGNIFICANT MODIFICATIONS TO THE SUNDAY THROUGH TUESDAY FORECAST
WERE MADE...THOUGH THAT MAY CHANGE SHOULD THE ECMWF JUMP ON BOARD
WITH THE DRIER SOLUTION IMPLIED BY THE NAM AND SHOWN BY THE GFS.

MARINE...
LIGHT AND VARIABLE WINDS...AND RELATIVELY CALM SEAS...ARE EXPECTED
OVER THE COASTAL WATERS THROUGH THE WEEKEND.
