AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
125 PM CDT TUE JUN 21 2011
.DISCUSSION...
FOR 18Z TAF ISSUANCE.
&&
.AVIATION...
REGIONAL 88DS SHOW PLENTIFUL CONVECTION ONGOING ACROSS THE AREA
NORTH OF I-10 AND ALONG/WEST OF HIGHWAY 165...WHICH HAS BEEN
ACCOUNTED FOR IN THE TAF INITIALIZATION AT KAEX/KLCH/KBPT THIS
AFTERNOON. FOR THE SERN SITES...EXPECTING SHOWERS/STORMS TO BREAK
OUT WITH HEATING OVER THE NEXT FEW HOURS AND HAVE INSERTED TEMPO
WORDING FOR THESE SITES STARTING AT 20Z. CONVECTION SHOULD
DIMINISH LATE AFTERNOON/EARLY EVENING AS THE SHORTWAVE HELPING
TRIGGER THIS ACTIVITY MOVES EWD...ALONG WITH THE LOSS OF DAYTIME
HEATING LATER. NO RESTRICTIONS TO VISIBILITY HAVE BEEN INCLUDED AS
OF YET ALTHOUGH SITES RECEIVING RAIN TODAY (WHICH WILL LIKELY BE
ALL) COULD WELL SEE FOG LATE TONIGHT IF SKIES CLEAR SUFFICIENTLY.
FOR TOMORROW A REPEAT IS POSSIBLE AS ANOTHER SHORTWAVE CROSSES THE
AREA AND INTERACTS WITH OUR LINGERING DEEP MOISTURE AND LEFTOVER
BOUNDARIES.
25
&&
.PREV DISCUSSION... /ISSUED 903 AM CDT TUE JUN 21 2011/
UPDATE...
LARGE FETCH OF MOISTURE MOVING IN FROM THE GULF WILL PRODUCE
SHOWERS AND THUNDERSTORMS TODAY. SOME THUNDERSTORMS WILL HAVE
NUMEROUS CLOUD TO GROUND LIGHTNING STRIKES AND HEAVY RAINS AT
TIMES. THIS WILL HOLD TEMPS BACK INTO THE MID TO UPPER 80S ON
SOUTH WINDS. HAVE MADE A FEW CHANGES TO THE ZONES FOR TODAY.
THIS PATTERN WILL PERSIST INTO THURSDAY BEFORE DECREASING.
PREV DISCUSSION... /ISSUED 630 AM CDT TUE JUN 21 2011/
DISCUSSION...
CONCERNING THE 21/12Z TAF ISSUANCE.
AVIATION...
TROPICAL-LIKE MOISTURE HAS MOVED INTO THE REGION AND THIS...COMBINED
WITH LOW LEVEL JET AND SURFACE MOISTURE CONVERGENCE...HAS ALLOWED
SCATTERED SHOWERS AND THUNDERSTORMS TO FORM FROM AROUND KAEX TO
KBPT/KLCH. FREQUENT LIGHTNING...WIND GUSTS TO 25 KNOTS...AND MVFR
VISIBILITIES CEILINGS CAN BE EXPECTED WITH THIS ACTIVITY THROUGH
THE MORNING HOURS. SCATTERED SHOWERS AND THUNDERSTORMS WILL THEN
REFORM THIS AFTERNOON AS MAX DAYTIME HEATING WILL COMBINE WITH THE
VERY MOIST ATMOSPHERE.
ACTIVITY WILL BEGIN TO DIMINISH IN AREA COVERAGE DURING THE
EVENING HOURS WITH THE LOSS OF DAYTIME HEATING. HOWEVER...WITH
TROPICAL LIKE MOISTURE HANGING AROUND...AND NOCTURNAL LOW LEVEL
JET EXPECTED...A FEW SHOWERS WILL CONTINUE THROUGH THE NIGHT...AND
THEREFORE WILL KEEP VCSH GOING AFTER 22/01Z THROUGH THE END OF THE
TAF PERIOD.
RUA
PREV DISCUSSION... /ISSUED 513 AM CDT TUE JUN 21 2011/
WELCOME AND BENEFICIAL RAINS TO CONTINUE THROUGH LATE WEDNESDAY...
SYNOPSIS...DEEP LOW PRESSURE OVER THE UPPER MIDWEST WITH AN
ASSOCIATED BROAD AND DEEP UPPER LEVEL TROF EXTENDING OVER THE
SOUTHERN PLAINS WILL CONTINUE COMBINING WITH A HIGH PRESSURE RIDGE
OVER THE SOUTHEASTERN STATES. THIS WILL CONTINUE A DEEP AND MOIST
FETCH OF TROPICAL MOISTURE OUT OF THE CARRIBEAN AND INTO OUR
REGION. MUCH NEEDED AND WELCOME PERIODS OF SHOWERS WILL CONTINUE
THIS WEEK FROM THIS SET UP. WHILE THIS RAIN OBVIOUSLY WILL NOT BE
SUFFICIENT TO END A DROUGHT GOING ON TWO YEARS, PRECIPITABLE WATER
VALUES OF AROUND 2 INCHES SHOULD BE ENOUGH TO GIVE US AN
ADDITIONAL 1 TO 2 INCHES OF RAIN THIS WEEK...GREATLY HELPING THE
PARCHED TOPSOIL AND DRY GRASSES.
SHORT TERM...AN MCS OVER NORTH TEXAS IS NOT EXPECTED TO BE A
PLAYER TODAY AS IT IS TOO FAR UPSTREAM. QUICKLY MOVING SHOWERS
SHOULD BE COVERING ABOUT HALF THE AREA TODAY WITH NO MORE THAN
ABOUT 30 PERCENT COVERAGE AT ANY GIVEN TIME. GUIDANCE HAS BEEN
DISCOUNTING THE LINGERING EFFECTS OF MID LEVEL RIDGING WHICH HAS
INHIBITED CONVECTION DESPITE HIGH MOISTURE CONTENT AND INSTABILITIES.
FOR THAT REASON AND A LACK OF A FOCUSING MECHANISM, I UNDERCUT
GUIDANCE AND WENT AGAIN WITH A 50 PERCENT POP. THIS PANNED OUT
WELL YESTERDAY. LATENT HEAT RELEASE EFFECTS AT NIGHT SHOULD AGAIN PERSIST
AND SO WENT ABOVE GUIDANCE ON POPS TUESDAY NIGHT. LOOKS LIKE WITH
THE GRADIENT LOOSENING, WE HAVE SEEN THE LAST OF THE RECORD HIGH
MINIMUMS THIS MORNING. SHOULD JUST SEE A FEW DEGREES ABOVE
SEASONAL NORMS TUESDAY NIGHT.
LONG TERM...WENT BELOW GUIDANCE ON POPS FOR WEDNESDAY. SURFACE
RIDGING FROM THE EAST SHOULD BE SUFFICIENT TO MITIGATE OUR PRECIP
CHANCES TO THE LOW END CHANCE CATEGORY. AGAIN WENT HIGHER THAN
GUIDANCE WEDNESDAY NIGHT IN THE SOUPY TROPICAL AIRMASS WHERE
LATENT HEAT WILL AGAIN BE RELEASED...NOT SURPRISING THAT MODELS
MISS ON THIS. BY FRIDAY AFTERNOON...WHAT REMAINS OF THE H5 TROF
AXIS WILL PASS TO THE EAST. UPPER LEVEL RIDGING BUILDING IN FROM
THE WEST WILL HELP SUPRESS RAIN CHANCES TO BELOW CLIMO. DID
MAINTAIN LOW END CHANCES ON SATURDAY WITH THE AREA BACK IN THE DRY
DOLDRUMS BY SUNDAY AS HIGH PRESSURE BUILDS IN FROM TEXAS.
MARINE...SEAS WILL BE SLOW TO SUBSIDE DESPITE THE WINDS SLIPPING
BELOW THE ADVISORY THRESHOLD. MODERATE SOUTHERLY TONIGHT,
DIMINISHING ON WEDNESDAY AS THE GRADIENT RELAXES.
