What happened

The episode as NWS SHV wrote it up.

A cold dome of arctic air spilled southward out of the Central and Southern Plains, into the Lower Mississippi Valley ahead of the Winter Storm event. The flow aloft was from the west southwest with embedded disturbances moving towards the region from West Texas. These disturbances provided the necessary lift to generate widespread winter precipitation across the region in the form of freezing rain and sleet. Temperatures during the predawn hours of February 23rd were mostly just above freezing but once the precipitation moved in from the west, the precipitation quickly changed over to freezing rain mixed with sleet as the temperatures fell during the day. Freezing rain and sleet accumulations were mainly less than one tenth of an inch across the region.

What forecasters said that day

The local office's own words before the first event, 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 the first event at Feb 23, 5:23 AM CST, 4 hours 37 minutes earlier.

.PREV DISCUSSION... /ISSUED 447 AM CST MON FEB 23 2015/

DISCUSSION...
FIRST ROUND OF PRECIPITATION MOVED OUT OF THE FOUR STATE REGION
SHORTLY AFTER MIDNIGHT BUT SINCE THAT TIME...THE SECOND ROUND OF
PRECIPITATION HAS BEEN RAPIDLY EXPANDING IN COVERAGE AND INTENSITY
TO OUR WEST ACROSS CENTRAL AND NORTH CENTRAL TEXAS. THIS IS IN
RESPONSE TO AN EMBEDDED DISTURBANCE CURRENTLY ACROSS THE TX HILL
COUNTRY MOVING RAPIDLY OUR WAY IN STRONG WEST SOUTHWEST FLOW
ALOFT. SFC TEMPERATURES AS OF 10Z THIS MORNING WERE NEAR TO BELOW
FREEZING ALONG AND NORTH OF THE I-20 CORRIDOR OF NORTHERN
LOUISIANA AS WELL AS SOUTHEAST OKLAHOMA AND SOUTHWEST ARKANSAS.
ACROSS NORTHEAST TEXAS...AREAS NEAR AND TO THE NORTH OF THE I-30
CORRIDOR WERE NEAR FREEZING AS WELL WITH THE I-20 CORRIDOR OF
NORTHEAST TEXAS AND POINTS SOUTH IN THE MIDDLE TO UPPER 30S. BEEN
WATCHING TEMPERATURES SINCE MIDNIGHT AND WHERE THE STRONGEST COLD
AIR ADVECTION RESIDES CURRENTLY ACROSS OUR EASTERN HALF...
TEMPERATURES HAVE BEEN FALLING ABOUT A DEGREE AN HOUR WITH ABOUT
A DEGREE EVERY TWO HOURS ACROSS OUR WESTERN HALF.

00Z RUN OF MODELS HAVE NOT CHANGED MUCH AS FAR AS PRECIP TYPE IS
CONCERNED AFTER EXAMINING MODEL THICKNESS AND SOUNDING DATA. WHAT
HAS CHANGED IS AMOUNTS AND FOR THAT REASON...HAVE SCALED BACK THE
WINTER STORM WARNING TO JUST INCLUDE EXTREME NORTHWEST LOUISIANA AND
THE NORTHERN HALF OF NORTHEAST TEXAS ALONG AND NORTH OF THE I-20
CORRIDOR. THOUGHT ABOUT REMOVING THE SHREVEPORT/BOSSIER METRO AREA
FROM THE WARNING AND JUST GOING WITH AN ADVISORY BUT TWO REASONS
HAVE LED ME AGAINST THAT THINKING. 1). THE OPERATIONAL HRRR/WRF/
GFS/ECMWF AND CMC ALL ALL HINTING AT AN AREA OF HIGHER ACCUMULATION
TOTALS ACROSS OUR NW ZONES LATER THIS MORNING THROUGH THE AFTERNOON
HOURS. SOME OF THESE MODELS ARE A LITTLE FURTHER NORTH WITH THIS
AXIS OF HEAVIER PRECIP WHILE OTHERS ARE SLIGHTLY FURTHER SOUTH...
WHICH COULD ENCOMPASS THE NORTHERN PORTIONS OF CADDO/BOSSIER AND
WEBSTER PARISHES. 2). THE LONG DURATION OF SUBFREEZING TEMPERATURES
TODAY INTO THIS EVENING...EVEN IF THE PRECIPITATION INTENSITY IS
LIGHT...COULD MAKE TRAVEL VERY HAZARDOUS. I MIGHT ADD THAT NONE
OF THE MODELS BRING THIS HEAVIER AXIS OF PRECIPITATION INTO THE
SHREVEPORT/BOSSIER METRO AREA AND SINCE I CANNOT SEGMENT THE
PARISHES LIKE I COULD A CONVECTIVE WARNING...EXTREME NORTHWEST
LOUISIANA REMAINS IN THE WINTER STORM WARNING. THERE DOES APPEAR
TO BE A VERY NARROW AXIS OF HEAVIER PRECIPITATION THAT COULD
DEVELOP ACROSS DEEP EAST TEXAS AS WELL AS WEST CENTRAL AND EAST
CENTRAL LOUISIANA SOUTH OF THE I-20 CORRIDOR AND GIVEN THE FACT
THAT TEMPERATURES ARE EXPECTED TO EITHER BE AT FREEZING OR QUICKLY
FALL TO BELOW FREEZING ONCE THE PRECIPITATION BEGINS...THIS AREA
COULD POSSIBLY SEE FREEZING RAIN ACCUMULATIONS NEAR ONE QUARTER OF
AN INCH AS WELL.

HAVING SAID THAT HAVE EXPANDED SPACIAL TIMING OF THE WARNING/ADVISORY
PACKAGE TO 03Z GIVEN THE FACT THAT THE SOME OF THE ABOVE MENTIONED
MODELS WANT TO HOLD ONTO THE PRECIPITATION INTO THE EARLY EVENING
HOURS...ESPECIALLY ALONG AND SOUTH OF THE I-20 CORRIDOR. OUR
NORTHERN MOST ZONES COULD BE DONE WITH THE PRECIP BY 00Z THIS
EVENING BUT WILL LET THE ONCOMING SHIFT MAKE THE DETERMINATION ON
WHEN TO CANCEL EARLY IF NECESSARY.

THE OTHER SIGNIFICANT CHANGE TO THE FORECAST WHICH DOES NOT
NECESSARILY INVOLVE WINTER WEATHER (BUT IT COULD) WAS TO RAISE
POPS SIGNIFICANTLY TUESDAY NIGHT INTO WEDNESDAY. UPPER TROUGH AXIS
ACROSS THE FOUR CORNERS REGION OF THE COUNTRY ACCELERATES QUICKLY
INTO THE SOUTHERN PLAINS TUESDAY NIGHT WITH PRECIPITATION LIKELY
BECOMING WIDESPREAD ACROSS ALL BUT OUR VERY NORTHERN MOST ZONES
DURING THE DAY WEDNESDAY. AT THIS TIME...KEPT JUST LIQUID MENTION
ACROSS NORTH LA INTO THE SOUTHERN HALF OF NE TX LATE TUESDAY NIGHT
BUT FURTHER NORTH...HAD TO MENTION A RAIN/FREEZING RAIN POSSIBILITY
GIVEN FORECAST LOWS TUESDAY NIGHT. THE NAM IS EVEN SUGGESTING A
RAIN/SNOW MIX UNDERNEATH THE TROUGH FOR WEDNESDAY BUT KEPT THE
FORECAST JUST LIQUID FOR NOW GIVEN THAT THICKNESS WERE QUITE A BIT
COLDER WITH THE TROUGH COMPARED TO OTHER OPERATIONAL PROGS.

OTHERWISE...WE SHOULD BEGIN TO SEE A NOTICEABLE WARMUP BY THE
WEEKEND INTO EARLY NEXT WEEK AND GIVEN THE WARM TEMPERATURES...
HAVE INTRODUCED THE MENTION OF THUNDERSTORMS (A WELCOME CHANGE)
FOR SUNDAY INTO MONDAY OF NEXT WEEK.

ONCE AGAIN...THANKS TO ALL MY SURROUNDING OFFICES FOR THEIR
COORDINATION EFFORTS THIS MORNING...13.
