The episode as NWS JAN wrote it up.
Winter precipitation struck the ArkLaMiss again for the second time in about a week. A continued cold airmass remained in place over the region thanks to several rounds of cold air intrusions over the ArkLaMiss. Moisture increased over the area ahead of an upper level disturbance. Precipitation began moving in from the west during the morning hours of Feb 9th. The Mississippi Delta saw only snow and had a dusting of snow on the ground by the noon hour. The remainder of the ArkLaMiss began as rain and slowly transitioned to a rain/snow/sleet mix as the morning and afternoon progressed. Temperatures slowly began to fall over the region and the rain transitioned to snow across the I-20 corridor by mid afternoon. As the upper level disturbance tracked east across the area, precipitation continued across the region with the Mississippi Delta continuing to see all snow. Portions of northeast Louisiana received from 1-2 inches of snow as a storm total. The wintry weather resulted in hazardous driving conditions and many accidents were reported.

NWS Jackson, MS wrote its last area forecast discussion before the first event at Feb 9, 10:24 AM CST, 3 hours 36 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1024 AM CST WED FEB 9 2011
.UPDATE...GOING FORECAST IS ON TRACK GIVE OR TAKE AN HOUR OR SO ON
TIMING AND PRECIP TYPE...BUT THAT IS GENERALLY IN THE NOISE OF THE
SYSTEMS EVOLUTION. FLURRIES HAVE STARTED ACROSS THE FAR NW COUNTIES
AND I LOOK FOR THIS TRANSITION TO CONTINUE AS THINGS PUSH EAST. THE
PRECIP ACROSS NW/N LA HAS A MORE CONVECTIVE APPEARANCE THAN THE
SNOWY LOOKING ECHOS OVER AR. THIS PRECIP AREA ACROSS NW/N LA WILL
PUSH EASTWARD AND INITIALLY BRING SOME LIGHT RAIN TO THE WESTERN
AREAS BEFORE COOLING ALOFT ALLOWS THE CHANGE OVER TO SNOW LATER
TODAY. YOU CAN BASICALLY TAKE THE SAME EVOLUTION WITH THE INITIAL
PRECIP STARTING AS RAIN WITH A CHANGE OVER TO SNOW FOR CENTRAL
SECTIONS OF THE CWA. THE FAR NORTH...AREA ALONG AND NORTH OF HWY
82...MAY ONLY SEE ALL SNOW WITH THIS AND NOT ANY INITIAL RAIN. THE
EXCEPTION TO THIS WOULD BE ACROSS THE NE PORTION WHERE THE ONSET OF
PRECIP WILL BE LATER AND THERE IS MORE TIME TO WARM...HOWEVER ONCE
THE PRECIP STARTS...THEN IT SHOULD NOT TAKE LONG TO CHANGE OVER TO
SNOW. THE FAR S/SE...IT MAY ONLY OCCUR AS RAIN WITH NO CHANGE OVER
OR A VERY LATE CHANGE OVER. THE OCCURRENCE OF THIS MORE RAIN
SOLUTION IS MORE LIKELY ACROSS THE SE COUNTIES.
AS FOR TIMING AND AMOUNTS...THINKING REMAINS SIMILAR TO PREV
THINKING AND FORECASTS. LATEST GRAPHICASTS PAINT THIS WELL AND I
WILL REFER TO THOSE SO I CAN KEEP THIS SHORT. SAME GOES FOR
AMOUNTS...WE MAY ADJ THESE GRAPHICS AS THINGS EVOLVE AND KEEP UP
WITH THE LATEST TRENDS.
I WILL SAY THAT THIS SYSTEM HAS OVER ACHIEVED TO OUR NW AND MAY DO
SO ACROSS PORTIONS OF OUR CWA. MY GUESS AT THIS POINT WOULD BE OUR
NW/N PORTIONS COULD SEE HIGHER TOTALS. THIS WOULD BE BASED OFF THE
SLIGHTLY FASTER(1-2 HRS) ONSET OF SNOW AND THAT SNOW/LIQUID RATIOS
WILL BE HIGHER ACROSS THE NORTH.
THIS WINTER EVENT WILL NOT BE A LONG DURATION EVENT...THERE WILL BE
A WINDOW OF 3-4 HRS WHERE THE HEAVIEST SNOW WILL FALL AS THE SYSTEM
EVOLVES AND MOVES EASTWARD. IN THIS WINDOW IS WHERE THE MAIN
ACCUMULATIONS WILL OCCUR BEFORE THINGS END AND EXIT TO THE EAST.
LASTLY...CURRENT WINTER STORM WARNING AND ADV ARE LOOKING GOOD AND
NO ADJ ARE NEEDED AT THIS TIME. /CME/
&&
.AVIATION...PRECIPITATION STARTING IN THE DELTA THIS MORNING WITH
LIGHT SNOW BEING REPORTED. STARTED THE WINTER PRECIP IN THE NORTHWEST
TAFS THIS MORNING THEN ACCUMULATING ACROSS THE NORTHWEST HALF OF THE
REGION DURING THE AFTERNOON...THEN SPREADING ACROSS THE REGION
OVERNIGHT. WITH THE WINTER PRECIP AND RAINS EXPECT CONDITIONS TO
WORSEN BY THIS AFTERNOON INTO THE OVERNIGHT HOURS WITH ICING...SNOW
ACCUMULATIONS AND A MIXED BAG OF RAIN AND LIGHT SNOW IN THE
SOUTHEAST. EXPECT MVFR TO IFR CEILINGS OVERNIGHT. THIS WILL CAUSE
SOME ICING ISSUES FOR FLIGHTS. CONDITIONS WILL IMPROVE FROM THE WEST
AS WE GET TO DAWN ON THURSDAY MORNING...BUT SURFACE ICE COVER WILL
CONTINUE FOR AREAS ALONG AND NORTHWEST OF THE NATCHEZ TRACE FOR
THURSDAY. WINDS FOR TODAY WILL BE FROM THE EAST NORTHEAST AT 5 TO 10
KNOTS AND FROM THE NORTH AT AROUND 5 TO 10 KNOTS FOR TONIGHT. /15/
