AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
1204 PM CDT THU APR 14 2011

.DISCUSSION...
ADDED SOME SLIGHT CHANCE POPS TO THE EASTERN ZONES FOR THE ONGOING
SHOWER ACTIVITY THAT CONTINUES TO MOVE NORTH FROM N CNTRL LA INTO
SRN AR. ALSO LOWERED MAX TEMPS FOR THIS AFTERNOON BY A DEGREE OR
TWO AREAWIDE DUE TO THE EXTENSIVE CLOUD COVER.

UPDATED PRODUCTS HAVE BEEN SENT.  /09/

&&

.PREV DISCUSSION... /ISSUED 1025 AM CDT THU APR 14 2011/

DISCUSSION...
POTENTIAL STILL EXISTS FOR SIGNIFICANT SEVERE WEATHER ACROSS
PORTIONS OF THE CWA TODAY. DRYLINE IS ALREADY BECOMING WELL
ESTABLISHED WEST OF DFW METROPLEX PER 14Z SFC ANALYSIS AND SHOULD
BE LOCATED ROUGHLY PARALLEL TO AND JUST EAST OF I-35 BY MID
AFTERNOON. THE SEVERE THREAT WILL CONTINUE INTO THE EVENING AND
OVERNIGHT HOURS AND EXTENDS AS FAR SOUTH AS THE I-20 CORRIDOR WITH
THE GREATEST THREAT TO THE NORTH.

SCATTERED SHOWERS CONTINUE THIS MORNING GENERALLY EAST OF A
TEXARKANA TO NATCHITOCHES LINE. NO MAJOR CHANGES ARE PLANNED TO
FORECAST FOR THE REST OF THE MORNING. ANOTHER UPDATE WILL LIKELY
BE SENT SHORTLY BEFORE NOON TO REMOVE MORNING WORDING FROM THE
ZONES.  /09/

AVIATION...
CEILINGS ARE PRETTY MUCH BEHAVING AS EXPECTED ACROSS MOST TERMINAL
LOCATIONS THIS MORNING. EAST TEXAS TERMINALS ARE SEEING MOSTLY VFR
CEILINGS WITH POCKETS OF MVFR ACROSS THE REGION. ELSEWHERE...VFR
CEILINGS AT OR AROUND 4-6KFT WERE PRETTY COMMON WITH THIS MOISTURE
QUICKLY APPROACHING THE MLU AND ELD TERMINAL LOCATIONS. ISENTROPIC
LIFT WAS SUFFICIENT TO PRODUCE ISOLATED SHOWERS ACROSS PORTIONS OF
NORTHWEST AND NORTH CENTRAL LOUISIANA BUT THIS SHOULD CONTINUE TO
TAPER DOWN THROUGH THE MORNING.

A VERY STRONG PRESSURE GRADIENT IS PRESENT ACROSS THE REGION TODAY
AND WITH SUFFICIENT MIXING...EXPECT TO SEE SUSTAINED WINDS NEAR 15KTS
WITH HIGHER GUSTS...ESPECIALLY ACROSS THE NE TX TERMINAL LOCATIONS.

BY LATE THIS AFTERNOON INTO THE OVERNIGHT HOURS...STRONG TO SEVERE
THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG AND AHEAD OF A DRYLINE
ACROSS NORTH CENTRAL TEXAS INTO SOUTH CENTRAL OKLAHOMA. THIS ACTIVITY
WILL PUSH INTO SE OK/SW AR/NE TX AND SW AR THIS EVENING INTO THE
OVERNIGHT HOURS. TEMPO AND VCNTY TSTMS ARE ALREADY IN MOST
TERMINAL LOCATIONS AND WILL CONTINUE THIS THINKING WITH THE 18Z
PACKAGE.

PREV DISCUSSION... /ISSUED 856 AM CDT THU APR 14 2011/

DISCUSSION...
SCATTERED SHOWERS HAVE DEVELOPED IN NW LA SOUTH OF I-20. THESE
SHOWERS WILL LIKELY BE CONFINED TO THE EASTERN HALF OF THE CWA
THROUGH THE REMAINDER OF THE MORNING. UPDATED WX/POP/QPF GRIDS FOR
THIS ACTIVITY. UPDATED PRODUCTS HAVE ALREADY BEEN SENT.  /09/

PREV DISCUSSION... /ISSUED 520 AM CDT THU APR 14 2011/

DISCUSSION...
TEMPERATURES RANGING FROM MID 60S WEST...TO MID 50S EAST. SKIES
ARE MOSTLY CLOUDY WITH SOME LOW CLOUDS OVER DEEP EAST TEXAS...BUT
MOST OF THIS IS CIRRUS A PLENTY. THE WATER VAPOR SHOWS MID AND
UPPER LEVEL DRY AIR OVER OK AND N TX...WHICH WILL CLEAR OUT THE
SKIES BY MID TO LATE MORNING AND ENHANCE THE SEVERE THREAT BY
TONIGHT. UNTIL THEN...WARM SUNSHINE WILL PUSH THE MERCURY INTO THE
LOW TO MID 80S TODAY. IT LOOKS LIKE MAV IS THINKING CLOUDY ALL DAY
WITH MID TO UPPER 70S. HOWEVER...MAV TEMPS DO IMPROVE FOR TONIGHT
AND THE REST OF THE SHORT TERM AND HAVE BEEN BLENDED INTO TOMORROW
AND THE WEEKEND. WE WILL MORE THAN LIKELY HAVE A LAKE WIND
ADVISORY FOR TOMORROW FOR MUCH IF NOT ALL OF THE AREA.

BACK TO THE WATER VAPOR...THE NEXT SYSTEM IS FAST ON APPROACH...NOW
OVER THE FOUR CORNERS AND IS STILL FORECAST TO WHIP EAST BECOMING
NEGATIVELY TILTED OVER THE PLAINS. WE WILL BE QUITE WARM AND
CAPPED MUCH OF THE DAY...BUT MID TO LATE AFTERNOON WILL SEE THAT
BEGIN TO CHANGE OVER THE NW CORNER OF THE CWA. NAM IS THE WORSE
CASE SCENARIO WITH A DOUBLE BARREL SURFACE LOW BY 03Z AND HAS I-30
CORRIDOR WITH HELICITY OF 350 TO 450 00-03Z INCREASING TO 500 BY
06Z. 0 TO 1 KM WINDS INCREASING FROM 30 TO 45 KTS. THE 850 TO 700
MB LAYER HAS 8 C/KM LAPSE RATES AND WET BULB ZERO HEIGHTS AROUND
9KFT. IN ADDITION...A PRETTY GOOD AXIS OF CAPE WILL DO BETTER THAN
2000 J/KG. WE HAVE INCLUDED NOT ONLY SOME MAY BE SEVERE WORDING
WHICH HAS BEEN EXPANDED SOUTH TO ALONG I-20...BUT THE I-30 CORRIDOR
TEXT WORDING INCLUDES VARIOUS POSSIBLE THREATS...ISOLATED TORNADOES
ALONG THE WARM FRONT BEOFRE SUNSET AND FOR HAIL AND DAMAGING
WINDS AHEAD OF THE DRY LINE/COLD FRONT DURING MUCH OF THE EVENING
HOURS. THE SYSTEM SHOULD WEAKEN A BIT BEYOND MIDNIGHT.

THE SPC HAS EXPANDED THE SLIGHT RISK FOR THEIR DAY ONE AND
INTRODUCED A MODERATE RISK FROM EXTREME NE TX...TO E OK/W AR AND
SE KN. THE MODELS ARE A BIT FARTHER SOUTH WITH THE WHOLE LOW
PRESSURE STACK AND THIS COULD BE A LONG EVENING AND OVERNIGHT
WITH ONGOING WEATHER. PERHAPS THE WORSE YET THIS SPRING ESPECIALLY
OVER NORTHERN AREAS.

LITTLE CHANGE TO EXTENDED AS MODELS ARE BACK AND FORTH A BIT WITH
THE RAIN...EURO IS THE MOST CONSISTENT OVER THE LAST FEW DAY AND
STILL LIKES BARELY CLEARING ONE SYSTEM AS THE NEXT BRINGS IN MORE
RAIN FOR LATE WEEK...HOPE SO. MEX BLENDED INTO NEXT WEEK. /24/

AVIATION...
MVFR CIGS CONTINUE TO SPREAD N ACROSS E TX THIS MORNING...BENEATH AN
EXTENSIVE CIRRUS CANOPY IN PLACE ACROSS THE REGION. THESE MVFR CIGS
SHOULD REACH THE RED RIVER OF SRN OK/NE TX BETWEEN 12-15Z...AND
COULD AFFECT THE SHV/TXK TERMINALS BRIEFLY DURING THIS TIME AS WELL
BEFORE THEY BEGIN TO MIX OUT BY MID/LATE MORNING. AS THE CIRRUS
CANOPY EXITS THE REGION FROM THE W BY LATE MORNING/MIDDAY...DIURNAL
HEATING WILL LEAD TO THE DEVELOPMENT OF A SCT CU FIELD AREAWIDE AS
LOW LEVEL MOISTURE ADVECTION CONTINUES...AND LOW CIGS THIS MORNING
LIFT. A STRONG UPPER LEVEL LOW PRESSURE SYSTEM WILL EMERGE OUT OVER
THE PLAINS LATE THIS AFTERNOON...WITH INITIAL SHORTWAVE ENERGY
EJECTING NE AHEAD OF THE LOW ACROSS NE TX/SE OK/SW AR HELPING TO
TRIGGER SCT STRONG/SVR CONVECTION BETWEEN 22-00Z...IN VC OF AN NW TO
SE ORIENTED INVERTED SFC TROUGH THAT WILL LIFT NWD THIS EVENING. THE
TXK TERMINAL WILL BE THE MORE PRIME LOCATION FOR SEEING CONVECTION
THIS EVENING...WITH ADDITIONAL REDEVELOPMENT LIKELY THIS EVENING AS
THEY PROGRESS NE ACROSS SE OK/SW AR/EXTREME NE TX. ADDITIONAL
CONVECTION WILL FIRE FARTHER W ACROSS SE OK AFTER 06Z...AND RAPIDLY
PROGRESS ESE ACROSS NE TX/SW AR AND NW LA THROUGH 12Z...ALONG A
STRONG COLD FRONT. THUS...WILL LIKELY MENTION VCTS FOR ALL TERMINALS
EXCEPT LFK WITH THE FROPA IN THE UPCOMING 12Z TAFS. BUT PRIOR TO THE
FROPA...MVFR CIGS WILL AGAIN REDEVELOP/SPREAD NNE ACROSS THE
REGION...BEFORE CIGS QUICKLY LIFT AFTER THE FROPA. SSE WINDS WILL
INCREASE TO 10-15KTS AFTER 15Z...WITH GUSTS TO 18-23KTS ESPECIALLY
DURING THE AFTERNOON AND EVENING. WINDS WILL VEER TO THE SW AND
DIMINISH SLIGHTLY LATE OVER E TX/SE OK/SW AR...WITH THE APPROACH OF
THE FRONT. /15/
