AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
1238 PM CDT FRI JUN 15 2012

.DISCUSSION...
18Z TAF PACKAGE.

&&

.AVIATION...
ISOLD DIURNALLY DRIVEN CONVECTION HAS DEVELOPED ACROSS THE
AREA...WITH INDIVIDUAL CELLS EXHIBITING LITTLE OVERALL MOVEMENT.
INHERITED TAFS ALREADY HAD VCTS...AND THIS WILL BE RETAINED GIVEN
THE NEAR IMPOSSIBLE TASK OF DETERMINING WHEN AND WHERE THESE CELLS
WILL FORM...ESPECIALLY AS OUTFLOW BOUNDARIES BECOME A LARGER PART
OF THE EQUATION. WILL MONITOR RADAR TRENDS AND AMD AS NEEDED...BUT
GENERALLY SPEAKING VFR IS EXPECTED TO PREVAIL TODAY AND TONIGHT.

.PREV DISCUSSION... /ISSUED 1049 AM CDT FRI JUN 15 2012/

UPDATE...A FEW SHOWERS HAVE DEVELOPED OVER ACADIANA WHERE
CONVECTIVE TEMPS ARE RUNNING A FEW DEGREES BELOW AREAS FURTHER
WEST...AND IN ZONE OF LOW LEVEL CONVERGENCE PER LAPS. WILL SEE
DEVELOPMENT OVER THE REMAINDER OF THE REGION OVER THE NEXT FEW
HOURS YIELDING SCATTERED CONVECTION FOR THIS AFTERNOON. PULSE
SEVERE POSSIBLE. ZONES LOOK GOOD AND SEE NO NEED FOR AN UPDATE AT
THIS TIME.

MARCOTTE

PREV DISCUSSION... /ISSUED 627 AM CDT FRI JUN 15 2012/

AVIATION...SCATTERED THUNDERSTORMS ARE EXPECTED TODAY, HOWEVER
TIMING AT ANY TERMINAL FOR A TEMPO GROUP IS PROBLEMATIC AT BEST.
LEFT VCSH OR VCTS IN FOR THE DAY. IFR VIS WILL BE POSSIBLE
IN ANY SHOWER OR STORM WITH RA, HOWEVER CEILINGS WILL LIKELY
REMAIN MVFR TO VFR. STORMS WILL DISSIPATE INTO THE EVENING.

PREV DISCUSSION... /ISSUED 425 AM CDT FRI JUN 15 2012/

DISCUSSION...HIGH PRESSURE IS GRADUALLY BECOMING ESTABLISHED
OVER THE SOUTHEAST STATES THIS MORNING, HOWEVER A MOIST AND FAIRLY
UNSTABLE AIR MASS REMAINS OVER THE CWA. THE LIGHT SOUTH FLOW HAS
LEAD TO A FEW SHOWERS AND STORMS ALONG THE COASTAL CONVERGENCE
ZONE THIS MORNING... AND WITH DAYTIME HEATING SCATTERED STORMS ARE
EXPECTED BY LATE MORNING TO AFTERNOON. A WEAKENING SHORTWAVE ALSO
STILL LINGERS OVER LA THIS MORNING WHICH WILL CONTINUE TO PROVIDE
MODEST SUPPORT FOR STORMS. CONVECTION IS EXPECTED TO BE MORE
CONCENTRATED ACROSS EASTERN SECTIONS OF THE CWA DUE TO MORE
MOISTURE. DRIER MID LVLS ARE EXPECTED OVER TX AND PWATS WILL
GENERALLY RANGE FROM AROUND 1.8" ACROSS THE EAST TO AROUND 1.6"
ACROSS THE WEST SECTIONS OF THE CWA. THROUGH THE WEEKEND HIGH
PRESSURE AT THE SURFACE WILL GRADUALLY BUILD IN FROM THE NORTHEAST
WHICH WILL KEEP THE AREA IN A MOIST SOUTH TO SE FLOW. A MID LVL
RIDGE WILL GRADUALLY BUILD INTO TX AND THEN ACROSS THE REST OF THE
SOUTH THROUGH THE EARLY PARTS OF THE COMING WEEK. THIS WILL SLOWLY
SHOVE THE WEAK SHORT WAVE CURRENTLY OVER LA SOUTH INTO THE EXTREME
NW GULF OR PERHAPS JUST TO THE COAST OF LA BEFORE IT DEEPENS AND
RETRO GRADES INTO S TX. WITH THE SHORT WAVE/UPPER LOW IN VICINITY
OF THE CWA AND WITH CONTINUED MOISTURE BEING PUSHED ACROSS THE
AREA AROUND THE SUBTROPICAL RIDGE, ISOLATED TO SCATTERED SHOWERS
AND THUNDERSTORMS CAN BE EXPECTED THROUGH THE WEEKEND AND THE
EARLY PART OF NEXT WEEK. BY THE MIDDLE OF THE COMING WEEK WINDS
WILL GRADUALLY INCREASE AS THE PRESSURE GRADIENT SLOWLY TIGHTENS
BETWEEN THE RIDGE TO THE NORTH AND LOWERING PRESSURE WELL TO THE
SOUTH. THIS WILL BE MOST NOTED ALONG THE COAST AND OVER THE
COASTAL WATERS.

MARINE...THE PRESSURE GRADIENT WILL GRADUALLY TIGHTEN ACROSS THE
COASTAL WATERS THROUGH THE WEEK AND INTO THE MIDDLE OF THE COMING
WEEK. THIS WILL CAUSE WINDS TO SLOWLY INCREASE TO NEAR OR AROUND
15 KTS OVER THE WEEKEND AND POSSIBLY TO NEAR 20 KTS BY WEDNESDAY
OR THURSDAY. THIS IN TURN WILL GRADUALLY BUILD SEAS AS WELL.
