AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
1107 AM CST TUE FEB 23 2016

.DISCUSSION...
UPDATED AS LACK OF INSTABILITY TRENDS HAVE RESULTED IN THE
EXPECTED WIDESPREAD RAIN...BUT LACK OF HARDLY ANY THUNDER...EVEN
ACROSS SOUTHERN PORTIONS OF THE REGION. IN ADDITION TO LESS
INSTABILITY...LOW LVL WIND PROFILES INDICATING LESS SPEED SHEAR
WITH A WEAKER LOW LVL JET THAN PREVIOUSLY THOUGHT. THUS HAVE
REMOVED SVR MENTION FOR SOUTHERN CWA...AND DECREASED MENTION OF
THUNDER AREAWIDE. ON A RELATED NOTE...AS LACK OF WARM AIR
ADVECTION HAS ALSO PLAYED A ROLE IN THESE TRENDS...HAVE ALSO
LOWERED AFTN HIGH TEMPS...ONLY EXPECTED A VERY FEW DEGREE RISE IN
AFTN HIGHS...AND NO INCREASE AT ALL FROM 10 AM READINGS NEAR THE
RED RIVER VALLEY...WHICH IS BEGINNING TO BE AFFECTED BY THE STG
COLD FRONT BEGINNING TO MOVE INTO THE AREA./VII/.

&&

.PREV DISCUSSION... /ISSUED 601 AM CST TUE FEB 23 2016/

AVIATION...
FOR THE 23/12Z TAFS...A MIX BAG OF FLIGHT CONDITIONS CAN BE
EXPECTED ACROSS THE TAF SITES THROUGH THE PERIOD AS A LOW PRESSURE
SYSTEM MOVES ACROSS THE REGION. EXPECT CEILINGS TO BE BELOW 1000
FT ACROSS ALL OF THE SITES UNTIL ABOUT 24/09Z AND VSBYS BELOW 5SM
THROUGH AT LEAST 24/00Z AS HEAVY SHWRS/THUNDERSTORMS MOVE ACROSS
THE REGION. ALSO...STRONG GUSTY WINDS CAN BE EXPECTED AROUND THE
LOW AS SFC WIND GUSTS COULD APPROACH 30 KTS AT THE TAF SITES.

PREV DISCUSSION... /ISSUED 510 AM CST TUE FEB 23 2016/

DISCUSSION...
WATER VAPOR IMAGERY INDICATES RICH MOISTURE PLUME ENTERING OUR WRN
CWA WITH A DEEPENING UPPER TROF OVER N CNTRL TX...BECOMING NEARLY
CLOSED OFF AS IT CONTINUES TO INTENSIFY. AT THE SFC...A STATIONARY
BNDRY REMAINS PARKED NEAR THE I-10 CORRIDOR WITH A LOW DEVELOPING
ALONG THE BNDRY IN S TX. THIS LOW IS PROGGED TO RAPIDLY INTENSIFY
AS IT EJECTS NEWD LATER THIS MORNING WITH THE BNDRY LIFTING NORTH
INTO OUR DEEP E TX COUNTIES AND MOST OF OUR LA PARISHES...PLACING
THESE AREAS IN THE WARM SECTOR THIS AFTERNOON. COMBINED WITH THE
INCREASING SHEAR PRESENT TODAY...LOCATIONS IN THE WARM SECTOR WILL
BE ON THE HOOK FOR SOME SEVERE STORMS THIS AFTERNOON WITH THE SFC
LOW TRACKING RIGHT ALONG THE SRN AND ERN SIDE OF OUR CWA. THREATS
WILL INCLUDE DAMAGING WINDS...LARGE HAIL...AND ISOLATED TORNADOES.
HEAVY RAINFALL RESULTING IN FLASH FLOODING IS A LESSER CONCERN AS
THE RAIN WILL BE BENEFICIAL TO THE REGION AFTER A DRY START TO THE
YEAR...BUT STILL CANNOT RULE OUT SOME ISOLD FLOODING WITH RAINFALL
RATES INCREASING THROUGHOUT THE DAY. TOTAL RAINFALL AMOUNTS STILL
LOOK TO RANGE FROM 1-3 INCHES WITH THE HIGHER AMOUNTS GENERALLY
NORTH OF THE I-20 CORRIDOR...AND LESSER AMOUNTS SOUTH WHERE DRY
SLOTTING WILL FIRST OCCUR...EFFECTIVELY CHOKING OFF THE RAINFALL.

THE OTHER BIG STORY WILL BE THE INCREASINGLY STRONG AND VERY GUSTY
WINDS...WHICH WILL RESULT AS THE AFOREMENTIONED SFC LOW BEGINS TO
RAPIDLY INTENSIFY AND EJECT NEWD ACROSS THE SERN HALF OF THE AREA.
THUS...HAVE MAINTAINED A WIND ADVISORY FROM LATE THIS AFTERNOON ON
THROUGH THE OVERNIGHT HOURS AND EARLY WEDNESDAY WITH SUSTAINED
WINDS FROM 20-30 MPH AND HIGHER GUSTS OF 40 MPH OR MORE EXPECTED.
ADDITIONAL LAKE WIND ADVISORY WILL MOST LIKELY BE NECESSARY FOR
THE REMAINDER OF WEDNESDAY BUT HAVE HELD OFF ISSUING FOR NOW WITH
THE IMMEDIATE FOCUS ON TODAY'S THREATS.

AS THE SFC LOW PULLS OUT OF THE REGION LATER ON WEDNESDAY...RAIN
WILL QUICKLY DIMINISH FROM WEST TO EAST BUT GUSTY NW WINDS WILL
PREVAIL BEHIND THE COLD FRONT THROUGHOUT THE DAY AS MENTIONED.
SKIES WILL GRADUALLY CLEAR WITH THE UPPER LOW QUICKLY EJECTING
JUST BEHIND THE SFC LOW AND TEMPERATURES WILL BE NOTICEABLY MORE
SEASONAL AND COOLER THAN WHAT WE HAVE SEEN FOR MUCH OF FEBRUARY.
DRY WEATHER WILL CARRY THROUGH THE REMAINDER OF THE WORK WEEK AND
INTO MUCH OF THE WEEKEND WITH THE NEXT CHANCE FOR RAIN RETURNING
LATE SUNDAY THROUGH EARLY NEXT WEEK AS THE NEXT COLD FRONT ARRIVES
IN THE REGION. /19/
