The episode as NWS OUN wrote it up.
A major winter storm impacted much of Oklahoma beginning on the morning of January 28th and continued through much of the day. While the storm produced a variety of wintry precipitation, its most significant impacts came with an extended period of heavy freezing rain across southern into parts of central Oklahoma. Significant icing on trees and power lines resulted in widespread damage to trees and power lines. The day before the winter storm was unusually warm for a January day in Oklahoma, with the high temperature at Oklahoma City at 65 degrees, which was 17 degrees above normal. However, that same day, a strong cold front was sweeping south down the Plains. By noon, the cold front had pushed into southern Kansas, bringing gusty north winds and a rapid decrease in temperature. Behind the front, temperatures were falling back into the 30s and 40s, and the freezing line at the surface was very near the Kansas-Nebraska border.
Overnight, and into the morning of January 28th, the cold front pushed through most of Oklahoma and all of western North Texas. The cold front had stalled to the south in northern Texas leaving a shallow cold air mass in place across much of the area to the north of the front, with the cold air gradually deepening towards northern Oklahoma. As an upper level low became better organized in the southwestern United States, it helped draw warm, moist air north from the Gulf of Mexico. This warm air was lifted over the dome of cold air and contributed to the development of widespread precipitation during the morning across much of Oklahoma. The shallow cold air mass north of the front placed a broad swath of southwest Oklahoma and central Oklahoma under-the-gun for a major icing event. During the afternoon, the precipitation increased in intensity, particularly over southwest Oklahoma, which then moved into parts of central Oklahoma. A pocket of drier air in the middle of the atmosphere quickly swept in behind the precipitation and started clearing it out of Oklahoma by late afternoon. At the same time, enough cooling was starting to occur in the warm layer of air aloft to change the precipitation over to sleet across parts of the area, including much of the Oklahoma City metropolitan area. Luckily, northern Oklahoma remained cold enough that snow was the dominant type, which accumulated several inches in some areas. During the evening hours, light snow continued over western and northern Oklahoma, while much of the remainder of the area, except for southeast Oklahoma, saw periodic freezing drizzle.
Overnight, and into the morning of the 29th, a surface low pressure developed over southeast Texas and began to move northeast towards western Louisiana. Behind this low, more widespread precipitation began to redevelop over west Texas. The area of precipitation pivoted through much of Oklahoma during the daytime hours in the form of snow. Localized heavier bands of snow produced reduced visibilities and substantial accumulations. One notable band set up from southeast Cleveland County, through northern Pottawatomie County, and into southwest Lincoln County. The large storm system finally moved east of the region by late evening on the 29th.
In total, the large storm system resulted in over 900 slip-and-fall accidents. Almost 90 accidents were reported, with over 200 non-life threatening injuries with the accidents. Almost 180,000 homes and business' were without power at the peak of the storm, several of which (mainly in SW Oklahoma) were without power for almost a week. The monetary value for the damage may not be known for a while, but estimates are well into the millions of dollars.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
1210 AM CST THU JAN 28 2010
.AVIATION...TAFS CONTINUE TO FOLLOW THE TIMING OF THE NAM AND ITS
THERMAL PROFILE FOR DETERMINING PRECIPITATION TYPE. A FEW SHOWERS
HAD BEGUN TO SHOW UP NEAR THE INITIAL FRONTAL ZONE OVER SOUTHERN
OKLAHOMA. AS A STRONGER FRONT CATCHES UP LATER TONIGHT...
FRONTOGENESIS WILL WORK WITH WEAKLY UNSTABLE AIR TO PRODUCE
CONVECTIVE SHOWERS AND POSSIBLY THUNDER FROM NORTH TEXAS UP TO
NEAR CENTRAL OKLAHOMA. A DEEPENING LOW LEVEL CYCLONE WILL INCREASE
THE WINDS SIGNIFICANTLY...AS HAD ALREADY BEGUN TO OCCUR AT 06Z.
MORE SUBSTANTIAL REDUCTION OF VISIBILITY FROM ICE AND SNOW WILL
OCCUR LATER IN THE DAY AND EARLY EVENING. ALTHOUGH NOT YET
REFLECTED IN THE TAFS...SOME BLOWING SNOW IS LIKELY AT WESTERN
OKLAHOMA SITES ONCE ACCUMULATION BECOMES SUFFICIENT.
&&
.PREV DISCUSSION... /ISSUED 959 PM CST WED JAN 27 2010/
UPDATE...
AS WE CONTINUE TO EVALUATE THE 00Z NAM RUN... IT APPEARS MORE LIKELY THAT
THE PRECIPITATION PHASE FOR CENTRAL AND SOUTHWEST OKLAHOMA WILL BE
MOSTLY ICE WITH THE SNOW OCCURRING MAINLY NEAR THE LAST PART OF THE
EVENT. WE WILL INCREASE THE RANGE OF POSSIBLE ICE ACCUMULATIONS TO
NEAR 3/4 OF AN INCH... WITH LOCALLY HEAVIER AMOUNTS POSSIBLE UNDER
SOME OF THE STRONGER CONVECTIVE ELEMENTS. HOWEVER... THERE
CONTINUES TO BE UNCERTAINTY REGARDING HOW QUICKLY TEMPS DROP BELOW
FREEZING TOMORROW AND THE LENGTH OF THE FREEZING RAIN VERSUS SLEET
PHASES. MOST ROADWAYS WILL LIKELY BE SLOWER TO ICE UP... EXCEPT
FOR BRIDGES/OVERPASSES... HOWEVER THERE CONTINUES TO BE A GREATER
CONCERN FOR POWER LINES AND TREE LIMBS.
PREV DISCUSSION... /ISSUED 824 PM CST WED JAN 27 2010/
UPDATE...
UPDATED THE FORECAST TO DELAY THE ONSET OF PRECIPITATION UNTIL
LATE TONIGHT WHILE ALSO REDUCING POPS ACROSS THE NORTHERN HALF OF
THE AREA. CURRENTLY RADAR INDICATES NO PRECIP OVER THE AREA AS A
SHORT WAVE RIDGE IS MOVING INTO THE SOUTHERN PLAINS. LOW LEVEL
MOISTURE IS ALSO LIKELY STILL TOO SHALLOW FOR DRIZZLE AT THIS
TIME. LATEST NAM CONFINES RAIN DEVELOPMENT TO SOUTHERN OK AND
WESTERN NORTH TEXAS THROUGH THE NIGHT. ALSO MADE SOME MINOR
ADJUSTMENTS TO PRECIPITATION TYPES TO SLOW THE ONSET OF FREEZING
PCPN ACROSS CENTRAL OK TONIGHT. THE MESONET INDICATES THAT THE
LEAD WIND SHIFT WAS MOVING THROUGH CENTRAL AND SOUTHWEST OK THIS
EVENING. TEMPERATURES DROP OFF STEADILY... BUT NOT DRAMATICALLY...
BEHIND THE FRONT... WITH NO FREEZING WEATHER CURRENTLY IN THE
STATE.
PREV DISCUSSION... /ISSUED 622 PM CST WED JAN 27 2010/
AVIATION...WE TRENDED TOWARD A SOMEWHAT LATER ONSET OF LOW
CEILINGS AND LIGHT PRECIPITATION THAT WILL OCCUR TONIGHT.
GENERALLY FOLLOWED THE TIMING OF THE NAM HUMIDITY AND
PRECIPITATION FIELDS. THE MOST SIGNIFICANT CHANGE IS AT KPNC AND
KGAG...WHERE AN INITIAL INTRUSION OF DRY ARCTIC AIR WILL PROVIDE
SEVERAL HOURS OF VFR CEILINGS. THE ANTICIPATED STORM SYSTEM LOOKS
TO UNDERGO ITS MOST SIGNIFICANT CYCLOGENESIS IN THE SOUTHERN TEXAS
PANHANDLE. THIS WILL KEEP MID LEVELS WARM ACROSS CENTRAL AND
SOUTHWEST OKLAHOMA...AND WESTERN NORTH TEXAS...RESULTING IN FZRA
AND PL ONCE THE ARCTIC AIR DRIVES SURFACE TEMPS BELOW FREEZING. WE
INTRODUCED SOME THUNDER FOR THURSDAY MORNING...GIVEN THE MAGNITUDE
OF THE DEVELOPING WARM NOSE ALOFT PER THE NAM SOUNDINGS. A
CHANGEOVER TOWARD MODERATE SNOW SHOULD OCCUR LATE IN THE PERIOD
OVER FAR WESTERN OKLAHOMA.
PREV DISCUSSION... /ISSUED 250 PM CST WED JAN 27 2010/
DISCUSSION...
MAIN ADJUSTMENTS TO FORECAST WERE TO DECREASE ICE POTENTIAL
ACROSS PARTS OF SOUTHERN OKLAHOMA AND NARROW THE POTENTIAL FOR
HEAVY SNOW TO WEST CENTRAL/NORTHWEST OKLAHOMA. THIS ALSO PLACES
AREAS ALONG AND NEAR I-44 IN HIGHER CHANCE FOR 1/4 TO 1/2 INCH
OF ICE ACCUMULATIONS. WILL LEAVE CURRENT WARNINGS AND WATCHES THE
SAME. STILL SOME POTENTIAL FOR FREEZING RAIN/ICE WITHIN THE WATCH
AREA.
RATHER WARM CONDITIONS HAVE DEVELOP AHEAD OF FRONTAL BOUNDARY THIS
AFTERNOON. QUICK COMPARISON OF SURFACE TEMPERATURES AND MODEL OUTPUT
INDICATES TEMPERATURES ARE NOT COLD ENOUGH NORTH OF THE FRONT AND
TOO WARM NEAR/WITHIN FRONTAL ZONE. THEREFORE...FREEZING RAIN MAY
ADVANCE QUICKER TO THE SOUTH DURING THE DAY THURSDAY. TRANSITION
BETWEEN SNOW/SLEET AND SLEET/FREEZING RAIN STILL UNCERTAIN BUT
EXPECT FREEZING RAIN ZONE TO BE FAIRLY NARROW THAT ADVANCES SLOWLY SOUTH
DURING THE DAY. WARM CONDITIONS OVER THE PAST TWO WEEKS AND PRECIP RATES
WILL LIMIT THE AMOUNT OF ICE ACCUMULATIONS ON EXPOSED SURFACES.
ACCUMULATING PRECIP WILL SHIFT EAST BY LATE FRIDAY MORNING AS 7-5H
TROUGH MOVES EAST OF THE FA. COLD SURFACE HIGH AND CLEAR SKIES
WILL PRODUCE OVERNIGHT LOWS IN THE TEENS AND SINGLE DIGITS BY
EARLY SATURDAY MORNING.
(DAYS 4 TO 7) MODEL GUIDANCE FOR DAYS 4 THROUGH 7 HAS CHANGED
VERY LITTLE WITH THE LATEST RUN... AND SEEMS QUITE REASONABLE.
THERE WILL BE SOME COMPLICATIONS WITH TEMPERATURES EARLY IN THE
EXTENDED PERIOD... WHICH WILL PARTLY DEPEND ON EXACTLY WHAT
HAPPENS WITH THE WINTER STORM TOMORROW AND FRIDAY. FOR NOW... THE
GS MOS LOOKS LIKE IT IS ON THE RIGHT TRACK.
ANOTHER STORM SYSTEM WILL ARRIVE MONDAY... BRINGING A CHANCE OF RAIN
DURING THE DAY ON MONDAY. ALTHOUGH THERE IS A SLIGHT POSSIBILITY OF
FREEZING RAIN IN THE NORTH WITH THIS NEXT STORM SYSTEM... THE MAIN
CHANCE FOR RAIN SHOULD OCCUR AFTER TEMPERATURES RISE ABOVE
FREEZING. A BRIEF CHANGEOVER TO SNOW MAY OCCUR IN THE EVENING
BEFORE THE PRECIPITATION ENDS.
A THIRD WEATHER SYSTEM WILL BRING ANOTHER CHANCE FOR RAIN ON
WEDNESDAY.
GENERALLY ZONAL FLOW NEXT WEEK WILL BRING TEMPERATURES BACK CLOSER
TO SEASONAL AVERAGES.
