The episode as NWS OUN wrote it up.
A large storm system moved well southwest and south of Oklahoma, but a significant wave rotating around the system moved over Oklahoma. Precipitation began on the 3rd, mainly in the form of rain. However, as the storm system neared the state, temperatures dropped to or just below freezing, supporting a change from rain to wet snow over western and northwest Oklahoma late on the 3rd and early on the 4th. The snow accumulated mainly on grassy surfaces, with some snow reported on elevated surfaces. No travel problems were reported with the snowfall.
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 Norman, OK wrote its last area forecast discussion before the first event at Feb 3, 5:46 PM CST, 1 hour 14 minutes earlier.

.PREV DISCUSSION... /ISSUED 303 PM CST WED FEB 3 2010/
DISCUSSION...
RAIN IS SPREADING SLOWLY NORTHEAST THIS AFTERNOON... AHEAD OF A
SUBSTANTIAL STORM SYSTEM. SURFACE TEMPERATURES ARE VERY NEAR
FREEZING OVER APPROXIMATELY THE NORTHWEST HALF OF OUR FORECAST
AREA. AS THE ATMOSPHERE MOISTENS FURTHER TONIGHT... THERE IS A
GOOD CHANCE THAT VERTICAL TEMPERATURE PROFILES WILL BEGIN TO
SUPPORT SNOW ACROSS OUR FAR NORTHWESTERN COUNTIES... AND PERHAPS A
MIX FARTHER SOUTH. SOME ACCUMULATION REMAINS LIKELY IN THE FAR
NORTH... BUT AMOUNTS ARE EXTREMELY UNCERTAIN... DUE TO THE
MARGINAL NATURE OF THE TEMPERATURE PROFILE AND THE RELATIVELY HIGH
QUANTITY OF PRECIPITATION EXPECTED. ASSUMING SNOW DOES OCCUR... IT
IS LIKELY TO BE OF THE VERY WET VARIETY... AND WILL MAINLY
ACCUMULATE ON ABOVE-THE-GROUND SURFACES... INCLUDING GRASS...
BRIDGES... ETC. DUE TO THE POSSIBILITY OF TRAVEL PROBLEMS... WE
HAVE ELECTED TO ISSUE A WINTER WEATHER ADVISORY FROM TONIGHT
THROUGH THURSDAY.
LITTLE CHANGE IS EXPECTED TOMORROW... AS TEMPERATURES REMAIN
NEARLY STEADY... AND PRECIPITATION CONTINUES IN A VERY MOIST
ATMOSPHERE WITH CONTINUING LIFT.
THE PRECIPITATION SHOULD BEGIN TO DIMINISH LATE TOMORROW IN THE
WEST... AND SLOWLY END FROM WEST TO EAST THURSDAY NIGHT INTO
FRIDAY.
COLD HIGH PRESSURE WILL BUILD SOUTH INTO THE SOUTHERN PLAINS THIS
WEEKEND... AND ANOTHER STORM SYSTEM IS EXPECTED TO ARRIVE AROUND
SUNDAY. THIS WILL PROVIDE ANOTHER OPPORTUNITY FOR SNOW... AGAIN
MAINLY ACROSS THE NORTHERN 2/3 OF OUR FORECAST AREA. AN EVEN
COLDER AIRMASS THEN ARRIVES FOR MONDAY... AND WILL REMAIN OVER THE
REGION AT LEAST THROUGH MID-WEEK. THERE ARE MODEL INDICATIONS OF
ADDITIONAL SNOW TOWARD THE END OF THE WEEK... BUT THAT IS BEYOND
THE RANGE OF THIS FORECAST.
