AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
824 PM CDT SUN JUN 5 2011

.UPDATE...WE'VE BEEN TRACKING THE MCS MOVING OUT OF THE ARKLATEX.
AS EXPECTED, IT HAS SLOWED IT'S SOUTHWARD MOVEMENT...HOWEVER
SURFACE REPORTS SHOW THAT IT CONTINUES TO SEND OUTFLOWS AHEAD OF
THE COMPLEX. WILL UP THE POPS FOR THE LAKES AREA OF SOUTHEAST
TEXAS AFTER MIDNIGHT TNITE TO 30 PERCENT. ALSO NOTED THE SEABREEZE
BOUNDARY LYING THROUGH SW LA ON OUR RADAR. COMBINED WITH A RAPIDLY
MOVING SHORTWAVE HEADING OUT SW OUT OF THE NATCHEZ AREA, WILL
MAINTAIN A SLT CHANCE OR 20 POPS FOR SW AND SCEN LA THROUGH THE
REMAINDER OF TNITE. TEMPS LOOKING ON TRACK...ANOTHER MUGGY NIGHT.

AVIATION...
SKIES TO REMAIN MOSTLY CLEAR THROUGH THE OVERNIGHT HOURS...VFR.

PREV DISCUSSION... /ISSUED 324 PM CDT SUN JUN 5 2011/

.RECORD BREAKING HEAT ACROSS THE FORECAST AREA...

DISCUSSION...
ALL OFFICIAL CLIMATE SITES WILL BREAK RECORD HIGHS FOR TODAY WHEN
THE CLIMATE DATA IS RUN LATER THIS AFTERNOON. SO FAR HERE AT LAKE
CHARLES WE HAVE BEEN UP TO 102F...WITH REMAINDER OF INLAND
OBSERVATIONS NEAR OR ABOVE THE CENTURY MARK. RADAR JUST NOW
BEGINNING TO SHOW A FEW SHOWERS BREAKING THROUGH THE CAP.

FORECAST AREA IS BETWEEN SURFACE AND UPPER LEVEL RIDGE TO THE
NORTH CENTERED OVER ARKANSAS...AND A TUTT LOW OVER THE WESTERN
GULF OF MEXICO. THIS HAS ALLOWED FOR CONTINENTAL FLOW OVER THE
FORECAST AREA...ALLOWING TEMPERATURES TO SOAR THIS AFTERNOON.
HOWEVER...ENOUGH MIXING TAKING PLACE TO DRAW DOWN SOME DRY AIR
ALOFT AND LOWER DEW POINTS IN THE 50S AND 60S...THAT APPARENT
TEMPERATURES ARE NEAR THE AIR TEMPERATURES AND BELOW HEAT ADVISORY
CRITERIA.

A WEAK SURFACE WAVE WAS ALSO NOTED ALONG THE SOUTHEAST LOUISIANA
COAST AND HAS NOT MADE MUCH PROGRESS TO THE WEST TODAY AS
EXPECTED...THEREFORE MAIN AREA OF CONVECTION HAS STAYED EAST OF
THE FORECAST AREA. STILL...WITH TEMPERATURES AS WARM AS THEY
AREA...COULD STILL SEE SOME POP UP SHOWERS FOR THE REMAINDER OF
THE AFTERNOON INTO THIS EVENING...THEN DIMINISH A FEW HOURS AFTER
SUNSET...SO WILL KEEP A 20 POP GOING THROUGH 06Z. AGAIN...ANY
THUNDERSTORM THAT CAN GET GOING WILL HAVE THE CHANCE TO PRODUCE
STRONG TO SEVERE DOWN BURST WINDS.

OVER THE NEXT COUPLE OF DAYS...TUTT LOW WILL MOVE NORTHWEST AS
SURFACE/UPPER LEVEL RIDGE BEGINS TO SLIDE AND BUILD BACK TO THE
EAST. THIS SHOULD ALLOW THE WEAK SURFACE WAVE OVER SOUTHEAST
LOUISIANA TO SLIDE OFF TO THE WEST AND ACROSS THE FORECAST AREA ON
MONDAY. THEREFORE...WILL GO WITH SCATTERED POPS FOR MAINLY MONDAY
AFTERNOON. WITH THE EXPECTED MORE CLOUD COVER AND SHOWERS...HIGH
TEMPERATURES WILL NOT BE QUITE AS WARM AS TODAY.

AS THE WEEK PROGRESSES...RIDGE WILL SET UP OVER THE SOUTHEAST U.S.
PROVIDING A MORE TYPICAL DEEPER SOUTHEAST FLOW...WHICH WILL HELP
BRING AFTERNOON TEMPERATURES DOWN TO MORE NORMAL LEVELS. STILL DO
NOT SEE ANY REAL FOCUS FOR SHOWER AND THUNDERSTORM ACTIVITY EXCEPT
FOR DIURNAL HEATING AND SEA BREEZE...THEREFORE...WILL KEEP POPS AT
THE SLIGHT CHANCE CATEGORY FROM TUESDAY ON WARD INTO NEXT WEEKEND.
OTHERWISE...IF WIDESPREAD SIGNIFICANT RAINFALL DOES NOT OCCUR ON
MONDAY...IT WILL NOT LIKELY OCCUR FOR THE REMAINDER OF THE
WEEK...ALLOWING EXCEPTIONAL DROUGHT CONDITIONS TO PERSIST.

OF NOTE...OZONE LEVELS ARE FORECAST BY TNRCC TO BE HIGH ENOUGH
THAT ANOTHER OZONE ACTION DAY WILL BE IN EFFECT FOR MONDAY FOR THE
GOLDEN TRIANGLE OF SOUTHEAST TEXAS.

RUA

MARINE...
MAINLY LIGHT AND VARIABLE WINDS FOR TONIGHT INTO MONDAY WILL
BECOME MORE OF A SOUTHERLY DIRECTION DURING THE WEEK AS HIGH
PRESSURE SETS UP EAST OF THE COASTAL WATERS. LIGHT WINDS AND LOW
SEAS SHOULD PREVAIL AWAY FROM ANY STRAY SHOWER ACTIVITY.

RUA

FIRE WEATHER...
HIGH FIRE DANGER WILL CONTINUE THROUGH THE REMAINDER OF SUNDAY.
VERY HOT AIR TEMPERATURES COMBINED WITH LOW DEW POINTS...WILL MAKE
FOR RELATIVE HUMIDITY VALUES BELOW 30 PERCENT. ON TOP OF
THAT...MOST GROUND FUELS REMAIN VERY DRY...WITH TODAYS HEAT AND
SUNSHINE CONTINUING TO DRY THEM OUT. A FEW SHOWERS AND
THUNDERSTORMS WILL DEVELOP THROUGH THE EVENING HOURS. THIS
ACTIVITY WILL PRODUCE GUSTY AND ERRATIC WINDS WITH STRAY LIGHTNING
STRIKES...HOWEVER NO WIDESPREAD SIGNIFICANT RAINFALL.

SOMEWHAT BETTER CONDITIONS ARE EXPECTED ON MONDAY AS A LITTLE MORE
IN THE WAY OF CLOUD COVER AND SHOWER ACTIVITY IS EXPECTED. THIS
WILL HELP LOWER AFTERNOON TEMPERATURES AND RAISE MIN RH VALUES TO
AROUND 35 TO 40 PERCENT.

A REMINDER...BURN BANS REMAIN IN PLACE FOR ALL OF SOUTHEAST TEXAS
AND LOUISIANA.
