The episode as NWS TSA wrote it up.
The combination of a slow moving upper level system moving east out of the rockies and a shallow cold air mass moving south into Oklahoma resulted in a widespread rain event across eastern Oklahoma from the evening of the 29th into the next night. Temperatures remained above freezing across much of eastern Oklahoma. However, across a large part of Nowata, Washington, Osage and Pawnee counties, the temperature did fall a few degrees below freezing. While the air temperature was below freezing in those counties, soil temperatures remained above freezing. Thus, roads did not become icy. Exposed objects such as power lines and trees did receive a thick coating of ice, however, as two to three inches of rain fell. Many tree limbs and power lines fell down due to this ice. As many as 18,000 homes and businesses had power outages.

ALL INDICATIONS STILL POINT TO FRONT BECOMING STATIONARY ACROSS WEST CENTRAL ARKANSAS INTO FAR SOUTHEAST OKLAHOMA TONIGHT AS SHALLOW COLD AIRMASS ENCOUNTERS HIGHER TERRAIN. RAINS WERE INCREASING IN COVERAGE AND INTENSITY IN AREAS NORTH OF THE FRONT AS STRONG ISENTROPIC LIFTING CONTINUED. OUN AND SGF SOUNDINGS SUPPORT THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS OVERNIGHT. RADAR STARTING TO SHOW SIGNS OF CONVECTION WITH SOME HIGHER REFLECTIVITIES DEVELOPING VICINITY OF TULSA AT THIS TIME. WILL KEEP A MENTION OF THUNDERSTORMS IN ALL ZONES FOR TONIGHT. MESONET TEMPERATURES ARE CURRENTLY NEAR AND SLIGHTLY ABOVE 32F IN THE WINTER WEATHER ADVISORY ZONES. AS RAIN INTENSITIES INCREASE THERE THE NEXT FEW HOURS AND WEAK LOW LEVEL COLD ADVECTION CONTINUES...EXPECT FREEZING RAINS TO DEVELOP. BEST CHANCE FOR ICING TONIGHT WILL BE ACROSS NORTHERN PARTS OF OSAGE AND WASHINGTON COUNTIES WHERE COLDEST AIR AND LOWEST DEWPOINTS WERE OBSERVED. WILL SEND UPDATED ZONES BY 8 PM TO MAKE SOME FIRST PERIOD ADJUSTMENTS. NO CHANGES WILL BE MADE TO WINTER WEATHER ADVISORY OR WINTER STORM WATCH. SOME OF THE TEMPERATURES CHANGES FOR THE TONIGHT PERIOD WILL NECESSITATE SOME CHANGES TO THE SECOND PERIOD...MAINLY ACROSS THE SOUTHERN AND EASTERN ZONES.

A SHALLOW LAYER OF COLD AIR WILL CONTINUE TO INVADE THE AREA IN THE WAKE OF A COLD FRONT THAT IS SLOWLY MOVING ACROSS SOUTHEASTERN OKLAHOMA AND WEST-CENTRAL ARKANSAS. WARM AIR OVERRUNNING THE COLDER AIR AT THE SURFACE WILL PRODUCE OCCASIONAL FREEZING RAIN OR RAIN THROUGH WEDNESDAY NIGHT. WITH THE TEMPERATURES RIGHT AROUND THE FREEZING MARK ACROSS EXTREME NORTHERN OKLAHOMA...MUCH OF THE PRECIPITATION WILL FALL AS FREEZING RAIN. THERE WILL BE THREAT FOR ELEVATED THUNDERSTORMS TONIGHT INTO WEDNESDAY NIGHT. A STRONG UPPER LEVEL PRESSURE SYSTEM WILL APPROACH WEDNESDAY EVENING...AND THIS MAY INCREASE THE THREAT FOR HAIL AS TEMPERATURES ALOFT COOL. ISOLATED SEVERE THUNDERSTORMS MAY BE POSSIBLE ON WEDNESDAY INTO WEDNESDAY NIGHT. LARGE HAIL WILL BE THE MAIN THREAT. .DISCUSSION... A SURFACE COLD FRONT CURRENTLY ACROSS SOUTHEASTERN OKLAHOMA AND WEST-CENTRAL ARKANSAS WILL CONTINUE TO SLOWLY MOVE TO THE SOUTH TONIGHT. WARM AIR ALOFT WILL CONTINUE TO OVERRUN THE SHALLOW COLD AIRMASS PRODUCING WIDESPREAD PRECIPITATION. MOST OF THE PRECIPITATION WILL FALL IN THE FORM OF RAIN. HOWEVER...THE SURFACE TEMPERATURE MAY BE COLD ENOUGH IN PORTIONS OF NORTHERN OKLAHOMA FOR THE PRECIPITATION TO FREEZE ON CONTACT WITH THE GROUND AND ELEVATED OBJECTS. WIDELY SCATTERED EMBEDDED THUNDERSTORMS WILL ALSO BE POSSIBLE NORTH OF THE COLD FRONT IN AN AREA OF MARGINAL INSTABILITIES AS THE LOW LEVEL JET INCREASES.
