What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Shreveport, LA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jan 25, 4:36 AM CST, 5 hours 5 minutes earlier.

Area forecast discussion, Jan 25, 4:36 AM CST, 5 hours 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
436 AM CST WED JAN 25 2012

.DISCUSSION...
THE MUCH ANTICIPATED RAIN EVENT IS ABOUT TO GET UNDER WAY. STRONG
UPPER TROUGH JUST WEST OF THE BIG BEND WILL SLOWLY WORK ITS WAY
EAST OVER THE NEXT 24 TO 48 HOURS. SW FLOW ALOFT IS PROVIDING A
CONTINUOUS STREAM OF RICH MID AND UPPER LEVEL MOISTURE. AT THE
SFC...A LOW WAS CENTERED NEAR SAN ANTONIO TX AND A WARM FRONT
EXTENDED FROM THE LOW NEWD TO BETWEEN KJSO AND KOCH AND EWD TO
NEAR KAEX. FOR MUCH OF THE NIGHT...WIDESPREAD SHWRS AND TSTMS HAVE
BEEN ONGOING ACROSS TX AND ERN OK IN AN AREA OF STRONG ISENTROPIC
ASCENT. PRECIP HAS REMAINED MORE SCATTERED IN NATURE ACROSS THE
FOUR STATE REGION...SO FAR.

AS THE LOW AND WARM FRONT MOVE NE TOWARDS THE CWA...THIS PRECIP
WILL SPREAD EAST AFFECTING MOST OF THE AREA. PW VALUES WELL ABOVE
CLIMO AND THE SLOW MOVING NATURE OF THE SYSTEM LEAD HIGH
CONFIDENCE TOWARDS THIS BEING A HEAVY RAIN EVENT. RAINFALL
AMOUNTS BETWEEN 1 AND 2 INCHES SHOULD BE WIDESPREAD BEFORE THE
RAIN ENDS EARLY FRIDAY. SOME LOCATIONS MAY SEE TOTALS BETWEEN 3
AND 4 INCHES.

ANOTHER CONCERN IS THE POSSIBILITY FOR SVR WEATHER TODAY. AS THE
SFC LOW MOVES NORTH...MOST OF THE CWA ALONG AND SOUTH OF I-20 WILL
BE IN THE WARM SECTOR. BULK SHEAR WILL BE SUPPORTIVE OF ORGANIZED
SVR WEATHER AND THE TSTMS ACROSS CNTRL TX ARE EXPECTED TO ORGANIZE
INTO A LINEAR MCS. THE PRIMARY THREAT WILL BE DAMAGING WINDS ALONG
ANY BOWING SEGMENTS OF THE MAIN LINE...WHICH WILL ALSO LIKELY BE
THE MAIN AXIS OF HEAVY RAIN. LOW LEVEL DIRECTIONAL SHEAR IS ALSO
QUITE IMPRESSIVE...ESPECIALLY JUST TO THE EAST OF THE SFC LOW.
THEREFORE...ISOLATED TORNADOES WILL ALSO BE A THREAT...MAINLY
ACROSS DEEP E TX AND W CNTRL LA CLOSER TO THE SFC LOW WHERE THE
0-1 KM WIND SHEAR WILL BE GREATEST AND WHERE THE HIGHEST INSTABILITY
WILL BE FOUND. THIS THREAT WILL GRADUALLY SHIFT EWD AS THE SFC LOW
TRACKS EAST.

RAIN CHANCES WILL LINGER THROUGH EARLY FRIDAY. MODEL GUIDANCE IS
IN GOOD AGREEMENT WITH THE POSSIBILITY OF SOME WRAP AROUND SHWRS
LATE THURSDAY AND INTO FRIDAY AS THE UPPER TROUGH FINALLY MOVES
ACROSS THE CWA. COLDEST OVERNIGHT LOWS ARE EXPECTED THIS WEEKEND
AFTER SKIES CLEAR AND WINDS BECOME RELATIVELY LIGHT IN COMBINATION
WITH A WEAK COLD FRONT PASSAGE SATURDAY. SLY FLOW EXPECTED TO
RETURN AT THE BEGINNING OF NEXT WEEK ALLOWING MOISTURE TO RETURN
AND TEMPS TO WARM. NEXT CHANCE FOR RAIN IS NOT EXPECTED UNTIL
TUESDAY OR LATER AS A COUPLE OF SHORTWAVE TROUGHS AND AN
ASSOCIATED COLD FRONT MOVE ACROSS THE REGION. /09/

&&

.AVIATION...
FOR THE 25/12 UTC ISSUANCE OF THE TERMINAL FORECAST FOR THE FOUR
STATE REGION...WILL PREVAIL THE FORECAST SITES...KLFK...
KTYR...KGGG...KTXK...AND KSHV...WITH MOSTLY IFR CEILINGS AND
VISIBILITIES FOR EAST AND NORTHEAST TEXAS...NORTHWEST
LOUISIANA...AND SOUTHWEST ARKANSAS...WHICH WOULD ALSO OCCUR FOR
OTHER AIRPORTS IN SOUTHEAST OKLAHOMA AND IMMEDIATE SURROUNDING
AREAS THROUGH THE 24 HOUR PERIOD. FOR NORTH CENTRAL LOUISIANA AND
SOUTH CENTRAL ARKANSAS TERMINAL SITES...KMLU AND KELD...WILL
PREVAIL MVFR FOR THE SITES...WITH TEMPO GROUPS OF IFR CEILINGS AND
VISIBILITIES. AFTER 25/15 TO 25/17 UTC WILL PREVAIL THE NORTH
CENTRAL LOUISIANA AND SOUTH CENTRAL ARKANSAS TERMINALS...KMLU AND
KELD WITH IFR CEILINGS AND VISIBILITIES. WILL ALSO INCLUDE VICINITY
OR PREVAIL PRECIPITATION OF LIGHT RAIN OR SHOWERS AND WILL HAVE TO
ALSO INCLUDE THE OCCURRENCE OF THUNDERSTORMS. THIS DUE TO THE
MOVEMENT OF A SURFACE LOW...OVER SOUTH TEXAS...WITH A WARM FRONT
REACHING EAST ACROSS SOUTH TEXAS AND ALONG AND NEAR THE LOUISIANA
GULF COAST. THIS LOW WILL MOVE NORTHEAST INTO EAST TEXAS DURING THE
DAY WITH THE WARM FRONT MOVING NORTH ACROSS EAST TEXAS AND INTO
NORTHWEST AND NORTH CENTRAL LOUISIANA BY 26/00 UTC. THE LOW WILL
HAVE SEVERAL INVERTED TROUGHS REACHING TO THE NORTH FROM ITS CENTER
AND A COLD FRONT TRAILING SOUTH FROM ITS CENTER AS IT DRIFTS
NORTHEAST. AN UPPER CLOSED LOW MOVING FROM WEST TEXAS EAST ACROSS
CENTRAL AND SOUTH TEXAS WILL BE CONTRIBUTING DISTURBANCES
ACROSS THE SURFACE SYSTEM TO HELP PROVIDE A WET AND UNSTABLE
ATMOSPHERE FOR RAIN AND THUNDERSTORMS. THE SURFACE LOW WILL BE
CENTERED OVER THE ARKLATEX EARLY THURSDAY MORNING AROUND 26/12 UTC
WITH A DRY SLOT STRETCHING SOUTHWEST FROM SOUTHWEST ARKANSAS ACROSS
EAST TEXAS AND NORTHWEST LOUISIANA WHICH MAY PROVIDE A PERIOD OF
VFR TO MVFR FLIGHT CATEGORIES WITH NO PRECIPITATION...BUT AS THE
SURFACE AND UPPER SYSTEMS CONTINUE TO MOVE OFF TO THE EAST AND
NORTHEAST...WRAP AROUND MOISTURE WILL RETURN PRECIPITATION AND
IFR TO  MVFR FLIGHT CATEGORIES INTO THE DAY THURSDAY THAT WILL
MOVE EAST IN TIME. MVFR TO VFR FLIGHT CATEGORIES WILL RETURN TO THE
NORTHWEST SECTIONS OF THE FOUR STATE REGION...SOUTHEAST
OKLAHOMA...NORTHWEST PARTS OF EAST AND NORTHEAST TEXAS...AND
NORTHWEST ARKANSAS AFTER 27/00 UTC AND OTHER AREAS OF SOUTH CENTRAL
ARKANSAS...NORTHEAST TEXAS...AND NORTHWEST AND NORTH CENTRAL
LOUISIANA NEAR 27/12 UTC FRIDAY. WINDS WILL SOUTHEAST TO EAST 8 TO
15 KNOTS AHEAD OF THE SURFACE LOW FOR MUCH OF THE AREA...AND
NORTHEAST OVER THE NORTHERN SIDE OF THE SYSTEM...NEAR THE INTERSTATE
30 CORRIDOR FOR MUCH OF THE DAY TODAY. WITH THE LOW CENTERED OVER
THE ARKLATEX AROUND 26/06 UTC THURSDAY...WINDS EAST OF THE CENTER
WILL BE SOUTH TO SOUTHEAST...AND NORTH OF THE CENTER NORTHEAST TO
NORTH...AND TO THE WEST OF ITS CENTER NORTHWEST TO WEST WINDS WITH
SPEEDS OF 7 TO 14 KNOTS. BY MID DAY THURSDAY AND DURING THE
AFTERNOON WINDS WILL BECOMING NORTH TO NORTHWEST. /06/
