AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
320 AM CST SAT FEB 16 2008

.DISCUSSION...

COMPLEX WX SITUATION OVER THE NEXT 24 HOURS. APPROACHING UPPER
LEVEL LOW WILL HELP INTENSIFY A SFC LOW THROUGH THE DAY. E WINDS
WILL GRADUALLY BECOME SE AND S...INTENSIFYING BY LATE IN THE DAY.
CONVECTIVE BAND IMPACTING AREA PRESENTLY WILL LIFT NE AND N WITH
LOCALLY HEAVY RAIN AND ISOLATED HAIL. AFTER MIDDAY EXPECTING A
MINOR LULL AS MORNING CONVECTIVE BAND MOVES OUT AND WEAKENS...WHILE
THE NEXT ROUND GETS ORGANIZED NEAR I 35. WITH THE FRONTAL
PROGRESSION...CONVECTIVE LINE WILL RACE EASTWARD DURING THE LATE
AFTERNOON AND THROUGH OUT THE EVENING...MAYBE NEAR RUSTON BY
MIDNIGHT AND PUSHING PAST MLU AN HOUR OR SO LATER.

AS WARM GULF AIR STREAMS N FROM THE MID TX COAST TODAY...DISCRETE
CONVECTION AHEAD OF THE CONVECTIVE LINE MAY BE SFC BASED IN THE
WARM SECTOR...THUS MODERATE RISK OF SEVERE IS OUT FOR SE TX
INCLUDING OUR LFK AREA. REST OF THE AREA IS UNDER A SLIGHT RISK OF
SEVERE...PRIMARILY FOR ELEVATED HAIL STORMS THIS MORNING...AND THE
THREAT OF LARGE HAIL AND HIGH WINDS WITH THE EVENING SQUALL LINE.
HOWEVER THE PROGRESS OF THE WARM SECTOR INTO OUR CWA WILL NEED TO
BE MONITORED FOR ISOLATED SFC BASED WARM SECTOR TORNADO THREAT
WITHIN AND DOWNSTREAM OF THE MODERATE RISK AREA. STRENGTH AND
TIMING OF WARM SECTOR INTRUSION WILL MAKE MAX TEMPS TODAY TRICKY
ONCE MORE. GOING NEAR 70 DEGREES SOUTHERN TIER...MID 60S I 20...
NEAR 60 DEG IN S AR. THE PROXIMITY OF TYR TO THE COLD AIR JUST TO
THE WEST...AS WELL AS PROXIMITY TO THE SFC TROUGH...MAKES TYR
CAPABLE OF BUSTING THE MAX TEMP EITHER DIRECTION.

THEN THE STORM EVENT IS OVER BY THIS TIME TOMORROW...AND FRONT
WILL USHER IN COLDER AIR INTO THE REGION. MONDAY LOOKS TO BE THE
COOLEST DAY.

PRECIP RETURNS TO THE AREA WEDNESDAY AS SOUTHERLY FLOW BRINGS GULF
MOISTURE BACK...WITH SW FLOW ALOFT. EXTENDED MODELS AGAIN HAVING
DIFFICULTY DISCERNING THE LONG RANGE FCST...AS IT REMAINS FAIRLY
PROGRESSIVE AND ZONAL WITH HARD-TO-TIME DISTURBANCES. MUCH OF THE
FAR REACHES OF THE FCST WILL CONTAIN LOW POPS AND PARTLY CLOUDY
SKIES. /17/

&&

.AVIATION...

SHOWERS AND THUNDERSTORMS ARE EXPECTED TO PERSIST ACROSS MUCH OF THE
ARKLATEX TODAY...THUS A BUSY DAY IS ON TAP FOR AVIATION INTEREST.
MOISTURE HAS RETURNED AND IS WELL IN PLACE ACROSS THE AREA...THUS
IFR CEILINGS WILL LIKELY LINGER THROUGH THE 12Z TAF PERIOD. SURFACE
OBSERVATIONS SHOW COLD FRONT CURRENTLY POSITIONED JUST NORTH OF
I30...BUT THIS FEATURE WILL LIKELY RETREAT DURING THE DAY AS A
SURFACE LOW STRENGTHENS IN CENTRAL TEXAS LATER TODAY. SEVERE STORMS
WILL LIKELY DEVELOP AHEAD OF THIS DEVELOPING LOW...AS MUCH OF THE
ARKLATEX IS IN A SLIGHT RISK CONVECTIVE OUTLOOK TODAY. SOUTHEASTERLY
TO SOUTHERLY FLOW SHOULD CONTINUE AT THE SURFACE THROUGH MUCH OF THE
UPCOMING TAF PERIOD AT MOST TERMINALS...AS MODELS HOLD OFF FROPA
UNTIL AFTER 12Z SUNDAY MORNING. AMENDMENTS WILL BE COMMON TODAY AS
THUNDERSTORMS DEVELOP. /11/

...SEVERE WEATHER WILL BE POSSIBLE THROUGH TONIGHT...

A POWERFUL UPPER LEVEL STORM SYSTEM IS POISED TO AFFECT THE FOUR
STATE REGION TODAY AND TONIGHT. THIS STORM SYSTEM APPEARS TO HAVE ALL
THE NECESSARY INGREDIENTS TO AID IN THE DEVELOPMENT OF LARGE HAIL AND
DAMAGING WINDS OVER THE FOUR STATE REGION.

FIRST...SURFACE LOW PRESSURE WILL INTENSIFY OVER EAST TEXAS TODAY...
PRODUCING SOUTHERLY WINDS THAT WILL ADVECT WARM SURFACE TEMPERATURES
AND HUMID GULF AIR INTO EAST TEXAS AND CENTRAL LOUISIANA BY THIS
AFTERNOON. SECOND...POWERFUL JET STREAM DYNAMICS WILL COMBINE WITH
VERY STRONG WINDS ALMOST A MILE OFF THE EARTHS SURFACE THIS AFTERNOON
TO PROVIDE A POWERFUL LIFTING MECHANISM FOR THE WARM...MOIST AIR IN
PLACE.

THIRD...COLD TEMPERATURES ALOFT ASSOCIATED WITH THE UPPER LEVEL
STORM MAY ENHANCE THE AMOUNT OF INSTABILITY IN PLACE. FINALLY...
AMPLE WIND SHEAR...OR THE CHANGE IN WIND DIRECTION OR SPEED WITH
HEIGHT...SHOULD ALSO BE IN PLACE SATURDAY AFTERNOON AND EVENING.

MOST OF THE SEVERE HAIL AND DAMAGING STRAIGHT LINE WINDS WILL BE
ASSOCIATED WITH A LINE OF STRONG THUNDERSTORMS...EXPECTED TO DEVELOP
ALONG A COLD FRONT THAT WILL MOVE THROUGH THE FOUR STATE AREA
BEGINNING LATE THIS AFTERNOON AND ON THROUGH AROUND MIDNIGHT. AND
WHILE ISOLATED TORNADOES MAY ALSO OCCUR WITHIN THE SQUALL LINE...ANY
DISCRETE THUNDERSTORMS THAT FORM IN THE WARM SECTOR AHEAD OF THE
SQUALL LINE...ESPECIALLY OVER DEEP EAST TEXAS AND TOLEDO BEND
COUNTRY...WOULD BE ESPECIALLY PRONE TO ROTATE...POSING A THREAT FOR
TORNADO DEVELOPMENT.

FURTHERMORE...LOCALLY HEAVY RAINFALL APPEARS TO BE A GOOD BET.
STRONGER THUNDERSTORMS MAY PRODUCE A QUICK 2 INCHES OF RAIN OR MORE
IN SPOTS...WHICH COULD RESULT IN THE PONDING OF WATER IN LOW LYING
AREAS. TOTAL RAINFALL AMOUNTS...BEFORE THE RAIN ENDS EARLY SUNDAY
MORNING...COULD REACH UPWARDS OF 4 INCHES.

STAY TUNED TO YOUR NOAA WEATHER RADIO...OR LOCAL BROADCAST MEDIA
OUTLETS...FOR THE LATEST INFORMATION CONCERNING THIS POTENTIAL SEVERE
WEATHER AND HEAVY RAINFALL EVENT. UP TO DATE WEATHER INFORMATION
MAY ALSO BE FOUND AT OUR WEBSITE BY GOING TO WEATHER DOT G O V...
THEN CLICKING ON SHREVEPORT.
