Area forecast discussion, Jun 12, 7:48 AM CDT, 4 hours 12 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
748 AM CDT TUE JUN 12 2012

.DISCUSSION...
UPDATE FOR RECENTLY ISSUED SEVERE THUNDERSTORM WATCH...IN EFFECT
FOR THE ENTIRE CWA UNTIL 2 PM. UPSTREAM MCS OVER NORTHERN
LOUISIANA HAS INDEED MADE MORE OF A SOUTHWARD TURN AS IT HEADS
INTO CENTRAL LOUISIANA. ALTHOUGH SOME WEAKENING DID OCCUR EARLIER...IT
HAS MAINTAINED ITSELF WELL FOR THE PAST COUPLE OF HOURS.
POP...WX...AND QPF GRIDS WERE UPDATED ACCORDINGLY...CLOSER TO THE
HIRES MODEL SOLUTIONS MENTIONED IN THE EARLIER DISCUSSION.

13

&&

.PREV DISCUSSION... /ISSUED 635 AM CDT TUE JUN 12 2012/

AVIATION...A LINE OF STORMS IS DROPPING SE INTO CENTRAL LA AND
WILL LIKELY IMPACT KAEX OVER THE NEXT HR OR TWO WITH GUSTY WINDS
AND LOW VIS AND CEILINGS POTENTIALLY INTO IFR OR LIFR CATS. ELSEWHERE
PERIODIC MVFR CEILINGS AND VIS MAY OCCUR THIS MORNING. LATER AND
TOWARD MID DAY THE LINE AND OUTFLOW BOUNDARY WILL CONTINUE SE AND
POSSIBLY IMPACT THE TERMINALS IN ACADIANA INTO SE TX AS MORE
SHOWERS AND STORMS DEVELOP. A TEMPO GROUP IS IN KAEX THIS MORNING, BUT
DUE TO UNCERTAINTIES ABOUT THE EVOLUTION OF THE LINE, NO TEMPO
GROUP WAS ADDED TO THE OTHER TAFS... JUST VCTS. WINDS WILL BE
SOMEWHAT VRB AT KARA, KLFT, AND KAEX THIS MORNING, BUT WINDS WILL
GRADUALLY BECOME SOUTH TO SOUTHWEST TODAY THROUGH THIS EVENING.

PREV DISCUSSION... /ISSUED 538 AM CDT TUE JUN 12 2012/

DISCUSSION...REGIONAL RADARS CONTINUE TO BE QUITE ACTIVE THIS
MORNING...AND DEPICT AN ARRAY OF MESOSCALE FEATURES. THE MCS THAT
TRACKED THROUGH SOUTHERN MS/SE LA EARLIER TONIGHT HAS RESULTED IN
A N-S ORIENTED OUTFLOW BOUNDARY CURRENTLY NEAR AN ALEXANDRIA TO
LAFAYETTE LINE...CONTINUING TO MOVE OFF TO THE WEST. AHEAD OF THIS
FEATURE...AN APPARENT GRAVITY WAVE WAS NOTED ON RADAR IMAGERY
PROPAGATING SOUTHWESTWARD ACROSS THE AREA...HELPING INITIATE THE
SHOWER AND THUNDERSTORM ACTIVITY CURRENTLY OVER SW LA/SE TX.
FARTHER NORTH...A MORE SIGNIFICANT CONVECTIVE COMPLEX WAS ROLLING
ESEWD THRU NRN LA/SRN AR.

UNUSUALLY LOW CONFIDENCE IN THE VERY SHORT TERM FORECAST...WHICH
WILL BE HEAVILY INFLUENCED BY THE AFOREMENTIONED FEATURES...ALONG
WITH THE APPROACH OF A SLOW MOVING FRONT CURRENTLY INVOF THE RED
RIVER VALLEY/SRN AR.

CONVECTION TO THE NORTH LOOKS TO PERHAPS BE LOSING A BIT OF
INTENSITY AS IT HEADS THROUGH NORTHERN LOUISIANA...WITH OUTFLOW ON
THE WESTERN FLANK STARTING TO OUTRUN THE CONVECTIVE CELLS.
DEPICTIONS BY HIGH RESOLUTION MODELS SHOWING A DECAYING MCS
TRACKING SOUTHWARD THROUGH THE AREA MAY NOT BE TOO FAR OFF THE
MARK...THOUGH DEFINITELY DISPLACED TOO FAR TO THE WEST AND MAYBE A
LITTLE TOO ROBUST WITH THE QPF. NONETHELESS...THESE SOLUTIONS ARE
MORE BELIEVABLE THAN THE GLOBAL MODEL SOLUTIONS...WHICH SHOW
LITTLE TO NOTHING IN THE AREA UNTIL LATER THIS AFTERNOON.
THUS...THE POP FCST FOR TODAY WAS BASICALLY A COMBINATION OF
CURRENT RADAR TRENDS PLUS AN EASTWARD SHIFTED HIRES MODEL
SOLUTION.

BEYOND TODAY...FRONTAL BOUNDARY TO THE NORTH IS EXPECTED TO
CONTINUE A SLOW SOUTHWARD MOVEMENT...REACHING THE I-20 CORRIDOR BY
THIS EVENING...THEN NEAR THE ALEXANDRIA AREA BY WEDNESDAY EVENING.
GIVEN THE PROXIMITY OF THE BOUNDARY...ITS ASSOCIATED MOISTURE
POOL...AND PERTURBATIONS IN THE NW FLOW ALOFT...THE RISK OF
ADDITIONAL TSTM COMPLEXES WILL REMAIN IN PLACE FOR THE NEXT FEW
DAYS IN ADDITION TO MORE TYPICAL DIURNAL DEVELOPMENT.

HEADING INTO THE WEEKEND...AN AMPLIFYING RIDGE OVER THE CENTRAL
CONUS IS EXPECTED TO DROP RAIN CHANCES BACK TO NEAR OR BELOW
NORMAL...WITH MORE TYPICAL SUMMER TIME CHANCES RETURNING EARLY
NEXT WEEK AS THE RIDGE BREAKS DOWN.

13

MARINE...
THE BERMUDA HIGH PRESSURE SYSTEM WILL BUILD WESTWARD INTO THE
CENTRAL GULF OF MEXICO OVER THE NEXT FEW DAYS. A GREAT PLAINS
COLD FRONT WILL TRAVEL SOUTH AND EAST INTO NORTHERN LOUISIANA
TODAY...COMING TO A HALT ACROSS CENTRAL LOUISIANA ON WEDNESDAY.
SCATTERED PREFRONTAL SHOWERS AND THUNDERSTORMS ARE POSSIBLE OVER
THE COASTAL WATERS.
