Episode Narrative Fresh on the heels of the record-setting blizzard that occurred a few days before, another significant winter storm affected the southern Plains. Snowfall totals reached a foot over parts of northern Oklahoma, with widespread totals of 4 to 8 inches over the northern 2/3 of Oklahoma.
A strong surface high pressure developed south out of Canada into Kansas early on the 8th behind a cold front, that finally moved into northern Oklahoma during the late morning and early afternoon hours. Behind the arctic front were very cold temperatures, with temperatures falling into the single digits, and even sub-zero readings across many areas of the northern and central Plains (sub-zero temperatures would soon overspread much of Oklahoma). Precipitation, some of it heavy, developed behind the front as a strong low-level jet transported relatively warm and more moist air north over-top of the front. Snowfall totals north of the Oklahoma/Kansas border totaled 6 to 10 inches, with northerly surface winds gusting over 30 mph.
During the day, the cold front made substantially more southward progress over the Texas panhandle into western Oklahoma, with additional heavy snow accumulations developing behind the boundary by late afternoon. Additional support for precipitation development had developed ahead of a potent mid-level disturbance that moved southeast toward Oklahoma. Normally, progressive storm systems such as this one would not big snow-producers over the southern Plains, but with strong warm advection and very cold temperatures at the surface and aloft (and getting colder through the event), snow growth was maximized, which in turn caused moderate to heavy snowfall to occur.
By mid evening, the main snow band had developed over northern Oklahoma, with moderate to heavy snowfall occurring over the northern two or three tiers of counties for several hours. Here, widespread totals of 8 to 12 inches of snow was reported, with even higher totals toward northeast Oklahoma. Further to the south, an area of moderate to heavy snowfall progressed east, but started a little later and did not last near as long. This included the Oklahoma City metro, although Will Rogers World Airport still managed to pick up almost 6 inches of snow. Even further south toward the Red River, lighter totals of 2 to 4 inches occurred due to the even later onset and quicker progression of the precipitation.
In addition to the snowfall, a strong pressure gradient created very gusty winds behind the front. The strongest winds were reported over western Oklahoma, as pressure rises were maximized behind the quickly moving cold front. Gusts to almost 50 mph created wind chill values well below zero as temperatures fell into the lower teens, which also caused considerable blowing and drifting snow. Farther north and east, blowing and drifting snow also became a significant issue, even with slightly lower wind speeds. Wind gusts over 30 mph were reported at times, with visibilities falling to an 1/8 of a mile at times in the heavier snow bands.
Around 240 injuries statewide were reported by the Oklahoma State Department of Health, with 33 injuries associated with around 84 automobile accidents. And, like last storm, there were fatalities (2) with this storm.
Event Narrative Four inches of snow was measured in Cordell. Wind gusts of over 35 mph were reported for several hours greatly reducing visibilities and causing considerable blowing and drifting of the snowfall.
